You've made what's called "Overflow" which you refer to as risers.

You'll have a much more solid casting. Awesome work though! I want to get into casting at home, I just haven't because of other stuff haha. You're doing some cool stuff here man

It's my favorite texture lol, I've probably spent hundreds of hours with a ball peen hammer texturing just about everything I make. Looks great on everything from knives to jewelry.
aluminum alloyed metals can change color with annealing. the spot is because your weld cooled at a quicker rate than the casting. If you anneal after repairing at 600-900 it should go away.
Just a note - for axe hafts (handles) the grain should be aligned with the direction of the axe blade for maximum strength and to minimise damage. Hickory is the best wood for handles but when I saw the grain at around 6:20ish it’s basically the opposite of what I look for in an axe handle. It might not make much of a difference in the short term and on axes of this length, but for longevity and to avoid issues on any longer axes in the future I’d always try and get that grain in line with the axe blade.
It's much more important that the grain doesn't run out than which orientation the rings are in. Those handles will be fine. I'd be more worried about the loose fit at the bottom of the eye. You should have to tap an axe handle home firmly with a baton or mallet, it shouldn't just drop onto a shoulder like that.
As far as the Tin Bronze staying sharp, I have made a straight razor out of Tin Bronze and, after 3 years of use, all the owner does is an occasional edge touch up. He uses it daily LOVE this video
I'm kicking myself for not remembering the book, but there was a knifemaker who did probably hundreds of test trying to figure out what the best method for quenching blades was to maximize edge retention his testing method was to cut short segments off of a rope with the knives, counting how many cuts he made, once he could feel the knives struggling, he called that his stopping point, it would be cool to see you try this with the bronzes, more controlled than chopping wood at the very least for those interested, his best method was to quench a blade 3 separate times, waiting 24 hours after each quench (waiting apparently made a huge difference, it started when he got interrupted before the 2nd quench, and he struggled for some time to figure out why that knife preformed so much better, until he remembered the interruption )
Bronze is a wonderful metal for marine use, it's tough, resilient and very corrosion resistant providing you take care of electrolysis. It makes a beautiful looking axe. Good job.
In the book The Odyssey, bronze was the material used for weapons. The phrase "the cruel bronze" is often used. That has stuck with me after reading it many years ago.
bronze wont bind up as much in a metal vs metal strike. meaning it wouldnt catch in an enemies shield (the iron band on the edge), a blade, or armour the same way other metals would. i imagine it would make it much better at puncturing chain mail or sliding in between armour joints.
@@NogrimStoneson What in the "Bronze Age" would you have been making "chain" mail from? When trying to make archaeological comparisons, it would be important to compare like with like - which would mean making some arsenic-bronze, rather than tin-bronze. Yes, the Wikipedia level of chemistry describes bronze as a tin-copper alloy, but since tin is a quite uncommon metal, a *lot* of archaeological bronze is arsenical. The reason is simple - they (Mediterranean metal workers) had to import tin from either Kazakhstan or Cornwall to make tin-bronze (once the small S.Turkey tin deposits became too expensive), while copper minerals often form together with arsenic minerals (indeed, copper-arsenic sulphide and relatives are still significant copper ores to this day) so smelting of poorly-sorted ore would naturally produce an arsenic bronze. You need to be *more* careful working with this stuff. But it's often the correct material to compare with for experimental archaeology. But you're already quite careful.
I understand that bronze swords were used as stabbing weapons but if I had a sword and saw a stab coming I would try to deflect it with my sword. I wonder how many bronze on bronze sword duels a sword would survive before having to be melted and reforged.
Except for the original users, 5000-odd years ago, the comparison would have been with a "proper flint axe" because there was no such thing as "steel" to cast and forge.
@@a.karley4672 And I get that. On the question: "Why didn't people in the past just use steel?" It's because they had to figure out the technology to manufacture it in the first place, so mostly furnace and forge construction. And even then comparing modern high-grade steel to anything historical isn't quite fair, since even medieval steel was far different in quality. So I guess in conclusion, modern steel is quite the miracle and it's performance is really a marvel, we shouldn't take it for granted, and in the past people were wonderfully creative to make due with the things they had available.
@@rhonin255 ISTR a comment a while back that "traditional" wrought iron work (principally decorative, that-century) effectively died in the mid-1970s because modern steels were too tough to work, compared to crucible steel, alloy steels etc. 98% the same composition ; vastly different properties.
Just like to say a thank you as I've been a viewer for some time and I really appreciate the time you spend explaining things that may be obvious to other metal workers and done without patronizing us viewers who may not be as knolagable.
You should mold in the "welding bars" into the top surface, so when you pour it, it won't just run off...but pool into a nice formed rod Either way...such an incredible design and build! Keep em coming!!!!
Thank you for your video. For those who are unfamiliar with sand casting, the top half of the mold flask frame is called the "Cope", the bottom half of the mold flask frame is called the "Drag", and the sand packing tool is called the "Rammer".

@@Shadrach666 Because I have seen a lot of casting videos that featured failed castings because they refused to do the basics despite being foundrymen, smartass.
Did you know that the most common version of aluminum bronze is called Nordic Gold? Nordic Gold is what the .10€, .20€ & the .50€ coins are made of. They choose that metal because it does not contain any metals that people would have a contact reaction with.
I actually really like how these look! The more orangey color looks really good with the tan of the wood! And that hammered edge is just an awesome finishing touch

I read a graph somewhere that tin bronze, after work hardening exeeds the hardness of mild steel so honestly it would make for an excellent hatchet edge. If you have any interest in history tou might find a ton of inspiration in how strong bronze appears in historical writing... they made cannons out of the stuff for example.
Yup high grade Tin/Bronze has higher hardness than low grade steel, however it has a lower melting point (and a much lower point that it loses strength and fails)
Great video thru and thru! What a wonderful blend of woodworking and metallurgy. The casting process was great, reminded me of freshman mfg processes class in college. I think the additional heft from the higher-density tin bronze help the hatchet function slightly better by removing bigger chips per chop. Maybe not as sharp and strong as steel, but much better corrosion resistance.
The difference in colour is a restult of the krystalline lattice forming differently, since it cooled faster, causing their atoms to allign differently. The colour would become uniform, if you heated it up, and then cool it down again (Tempering). Depending on how hot you make it, and how fast you cool it you alter the properties of the metal quite drastically. It will make it softer or harder, depending on how much you heat it, and how quickly you cool it down again. Quick cooling will make it Hard and Brittle, slow cooling will result in it becming Soft and Ductile. If you are proficient in tempering, you can make the edge hard, while keeping the core and body soft, which will cause your axe to hold an edge for longer, and prevent it from chipping easily. I know how to do this with pretty much any Steel, but that one i am not familiar with. You can test it by casting or forging rods, then heat them and cool them differently and see the results by seeing how much the bend before breaking, and how much force it takes. This however requires specialised equipmen, but there is shops who wil gladly test these for you for a fee. also you can look it up, there have been tests on this very material, and the results should be publically available.
Thats for iron alloys, not copper alloys, iirc it also dont work with most other alloys ether Copper and copper alloys will just go soft if you heat them regardless of how fast or slow you cool i down. That's why you have to work harden copper and bronze if you want it hard.
@@just_that_crazy5179 bronze of the bismuth variety, if i remember correctly it's an alloy of bismuth (obviously), zinc and copper and it looks neat, but i don't know how durable it is.
@@Minty1337its mostly a self lubrecating alloy Their are basically infinite versions of bronze some work as expected some do something compleatly unexpected Black bronze looks neet but is 8% silver and 8% gold so get expensive quickly
@@aggese only 8% silver doesn't seem too bad, but the gold is a bit ouch. yea its weird how easily copper seems to 'bond' with other metals and produce funky alloys, and they all got such unique colors and properties too, far more fun than steel alloys in my opinion.
There is another ancient bronze that was used that you want to stay away from even though it is actually pretty good, Arsenical Bronze. Arsenical Bronze contains between 1% and 12% Arsenic (yes a Toxic Heavy Metal), with the rest Copper (and sometimes Tin), making this stuff can cause serious health problems and even death. A number of Copper Ores contain significant amounts of Arsenic (Enargite, Olivenite and Tennantite), likely the first accidentally discovered alloy and type of bronze, but due to the improved characteristics it was likely deliberately manufactured fairly quickly. Highly levels of Copper and Arsenic were discovered in Ötzi's hair (Ötzi, The Iceman, is a 3000+ year old (Chalcolithic, Copper Age) natural mummy found in ice along the Austria-Italy border), suggesting he was involved copper smelting and that they were using some of these copper/arsenic ores.
I set up and operated a non ferrous foundry in the 1990s. Though I did not work with aluminum bronze, I seem to remember reading the strength of this alloy is approaching the strength of mild steel. I most worked with brass, german silver and silicon bronze. BTW, it was a lovely job in winter, LP gas fired furnace kept us so warm!
In early bronze age you would have more likely found arsenical bronze. It's mechanical charateristics are comparable to tin bronze, but it's not industrially made, and a DIY would be pretty dangerous, for obvious reasons.
I recall that arsenic bronze kind of happens by itself. The arsenic is present when the copper ore is mined. You have to purify the copper to avoid getting bronze.
You should do a razor next. Romans were clean shaven with large round bronze razors with work hardened edges. Since then we switched to carbon steel and sharpening, but I’ve always wondered how bronze would perform!
Bronze is also anti-microbial, which explains how Roman surgeons were able to perform complicated surgeries without antibiotics - their scalpels and other instruments were all made of bronze !
Probably comparable as far as use goes. Even though steel is harder, that comes into play only in edge retention properties, meaning steel holds its edge longer before resharpening is required. That said a bronze shaving knife would be badass and I would totally buy one if available. Bronze is so beautiful.
True! Something that people don't think so much about is how we actually had "shaving sharp" blades in antiquity. Not everybody was walking around with grizzled beards and crudely-cut hair, and it's not like the Romans had genetic factors giving them boyish faces. The middle and upper classes had access to some properly razor-sharp blades for a baby's-butt-smooth shave.
I had cast a few bronze swords (just for fun) and they do not like chopping. I lack the set-up to cast them very thin, but the thick swords end up bending and twisting while chopping. This makes me want to cast a tin bronze axe now. I even have a spare axe handle... hmm.
I remember hearing about how Greek soldiers used to have to pound their swords back into shape during a skirmish, so maybe your not too far off with this..
@@edgeldine3499i think that may be a reference to Gaulish warriors using iron swords, which would have been what we call “wrought iron,” but it’s plausible that similar issues might be had with varying qualities of bronze available before modern scientific metallurgical knowledge. Often bronze swords were not made with full tangs, to save cost, and the blade would be riveted to the handle. These rivets were subject to breakage especially with slashing attacks, so bronze was often limited to short thrusting swords, arrowheads, and spearheads. Many of these short swords would only be sharpened at the point, the sides were left dull. The ancient Greeks also used a bronze sword with an incurving blade, called a _kopis_ , likely derived from the earlier Egyptian scythe-like _kopesh_ .Hammering the edge of the blade causes the metal to expand along the length of the blade as it is made thinner; this pushes against the C-shaped blade, which keeps the metal under compression and increases its hardness without becoming brittle. There was also a double edged pattern described as a “leaf shape”, which had incurving sides, taking advantage of this compression principle to allow sharp edges for slashing. When iron started to replace bronze, they would be made in the same patterns, until smiths learned how to take advantage of the different properties it afforded . This can be observed in the early versions of the Roman _gladius_ with its “narrow-waisted” appearance.
One note, you've made metal axe that looks like a metal axe, but in Ancient times for quite a long time they made metal axes that look like stone axes, with huge bulbous convex edges that were basically indestructible. It took a long time for the form to adapt to the material properties.
Not so - the earliest Bronze Age axes were diminutive and gracile. During the Chalcolithic they quickly evolved into gracile types - and the sheer cost and difficulty of extracting and melting enough metal to make an axe means they were small. If you held original early axes in hand, you would see they are much smaller than you imagine - often smaller than a man's hand, narrow butt and thin. That's why they used relatively large wooden handles, to add weight for cutting.
Bronze is a fantastic material for tools and weapons. The reason it was ditched for iron when humanity moved to the Iron Age, wasn’t primarily because iron was superior in. performance, but because it was everywhere, and it was cheap. The only reason it wasn’t used prior to that was that no one had figured out how to work it.
@@davidpowers9178 That’s part of it, but most of it is because of logistics. Most of warfare comes down to logistics frankly. Bronze was a good material but relied upon massive trade networks and cooperation between empires. The moment iron working became readily accessible, it destabilized the entire political ecosystem. For the first time, even small nations could afford to equip armies with high quality arms and armor. The massive advantage that rich nations had enjoyed for millennia evaporated over the course of a century or two, and only a couple of them survived into the new era, and them, significantly diminished.
@@davidpowers9178steel wasn’t really in use until the Middle Ages - smiths in India developed a technique of hammering carbon (from the charcoal fuel in the forge) into iron, producing small pucks of steel called “wootz.” Somehow this knowledge reached Sweden, presumably through the far-ranging trade contacts of the Varangians, who also served as Imperial guards at Constantinople, and there smiths learned to pattern weld these pucks into swords made with steel, superior to anything else in Europe at the time, giving the Vikings an edge over the competition thus enabling them to conquer much of Europe, Russia, and the lands around the Mediterranean .
Im surprised youre surprised bronze axes work. You know in my langauge the word for bronze is vara meaning force/power cos in the bronze age those who had bronze and not stone had the stuff.
I'd be interested to see how they compare to the non sparking tools of today. Beryllium Copper is what is used now and it's dust is toxic from what I understand. I cast my own aluminum bronze axe head about 10 years ago, but never got this far because I made the eye way undersized. It was clunky
Oh hey a Vegas TH-camr? And of something that i enjoy too. This video was pretty neat. And yeah 8:12 haha we don't really have anything to test an axe on any trees that don't exist going outside the city limits. Got to travel far north in Nevada to find any real woodlands. Born and raised here in Vegas myself so it's cool to see content creators from my city.
The design looks identical to my Helko Rheinland hatchet. Loved this video, I wish more things were made in bronze, even if it is more expensive, it just looks so cool and premium
Great video! I handled a bronze sword blade I believe 3000 years old from the Middle East. It was in amazing condition and the edge was still sharp. I have never underestimated bronze tools and weapons ever since. I was living near UNGH (university of North Carolina) a few years ago and there was a book in their library that showed details of hundreds of bronze weapons.
This would be the ultimate material for making acoustic drums. Aluminum rings like a bell and bronze has a lower register but is super cutting and excites the room.
On another channel (Metatron) a medieval and ancient warfare/history enthusiast was discussing how bronze was a lot tougher than most modern people give it credit for, stating that bronze weapons were still serviceable options for ancient warriors and people thousands of years ago, even with the introduction of iron weapons. They would not have had access to machines and pure ores but you just proved to me at least that our ancestors, using tin bronze, would have had wicked edged tools and weapons of bronze. Really enjoyed this. Thank you.
These are awesome. And they’re probably even better than they seem here because the other end of the wood wasn’t supported, so the movement likely took a lot of energy out of your hits
Copper and aluminum both conduct heat extremely well. Copper also changes color on its surface with heat, due to oxidation, depending on how hot it got. When you TIG welded, you made a hot spot. The heat spreads outward, very quickly. Once the copper gets hot enough to oxidize, it will. Just around the TIG weld, the IG controls oxidation, but once the heat gets outside of the inert gas, it oxidizes.
@aggese it really is a art. Ratios, temperature, cooling rate, cooling time, reheating and tempering among others can all cause vastly different outcomes.
the airpods in while narrating gives the same vibes as someone who comes into my cafe and asks for a latte and throws a 10 dollar bill on the counter ngl
A lovely job you've done with these. A couple of small points about the hafting of your heads. Hickory is a good choice, however when you choose your wood for the handle, the grain should run in line with the length (about 90 deg from what you have). this will lessen the likelihood of you splitting the length of your handle on impact. Additionally, there is no reason to use the metal wedges, they will add nothing to the holding. Some would argue that by splitting your (wood) wedge, that you have now actually weakened the hold of your wedge. These are just "fine points". I don't want to detract from your very fine work here.

aluminum alloyed metals can change color with annealing. the spot is because your weld cooled at a quicker rate than the casting. If you anneal after repairing at 600-900 it should go away.
That’s interesting! Thanks for letting us know
Just a note - for axe hafts (handles) the grain should be aligned with the direction of the axe blade for maximum strength and to minimise damage. Hickory is the best wood for handles but when I saw the grain at around 6:20ish it’s basically the opposite of what I look for in an axe handle. It might not make much of a difference in the short term and on axes of this length, but for longevity and to avoid issues on any longer axes in the future I’d always try and get that grain in line with the axe blade.
that does make sense. i suppose the wood is less likely to delaminate or fracture that way. thanks for the info.
I knew something looked off about them. Good eye.
It's much more important that the grain doesn't run out than which orientation the rings are in. Those handles will be fine. I'd be more worried about the loose fit at the bottom of the eye. You should have to tap an axe handle home firmly with a baton or mallet, it shouldn't just drop onto a shoulder like that.
also important is not to get half heartwood and half sapwood, to avoid warping problems.
Hickory? Baaah. There’s an Irishman who’s quite adamant about Ash.
As far as the Tin Bronze staying sharp, I have made a straight razor out of Tin Bronze and, after 3 years of use, all the owner does is an occasional edge touch up. He uses it daily LOVE this video
Impressive!
I'm kicking myself for not remembering the book, but there was a knifemaker who did probably hundreds of test trying to figure out what the best method for quenching blades was to maximize edge retention
his testing method was to cut short segments off of a rope with the knives, counting how many cuts he made, once he could feel the knives struggling, he called that his stopping point, it would be cool to see you try this with the bronzes, more controlled than chopping wood at the very least
for those interested, his best method was to quench a blade 3 separate times, waiting 24 hours after each quench (waiting apparently made a huge difference, it started when he got interrupted before the 2nd quench, and he struggled for some time to figure out why that knife preformed so much better, until he remembered the interruption )
Underrated comment, should be pinned, what liquid did he use?
Sounds like an older Pete of Cedric and Ada yt fame.
The grandpa of CATRA tests 🙂.
I have no idea who it was, but I could see Larrin Thomas take on a project like that.
3 quenched with a day between was best huh? I've never heard of that - or anything like it. VERY interesting.
Bronze is a wonderful metal for marine use, it's tough, resilient and very corrosion resistant providing you take care of electrolysis. It makes a beautiful looking axe. Good job.
The pour was so on point the lines from the 3D molds was even cast. Impressive.
In the book The Odyssey, bronze was the material used for weapons. The phrase "the cruel bronze" is often used. That has stuck with me after reading it many years ago.
I hear ya! I was wondering the whole time when we'd see the test of trying to hack through a Trojan's armor...
bronze wont bind up as much in a metal vs metal strike. meaning it wouldnt catch in an enemies shield (the iron band on the edge), a blade, or armour the same way other metals would.
i imagine it would make it much better at puncturing chain mail or sliding in between armour joints.
I remember the description of arrows and speartips going through the diferent tlayers of the shields...
@@NogrimStoneson What in the "Bronze Age" would you have been making "chain" mail from?
When trying to make archaeological comparisons, it would be important to compare like with like - which would mean making some arsenic-bronze, rather than tin-bronze. Yes, the Wikipedia level of chemistry describes bronze as a tin-copper alloy, but since tin is a quite uncommon metal, a *lot* of archaeological bronze is arsenical. The reason is simple - they (Mediterranean metal workers) had to import tin from either Kazakhstan or Cornwall to make tin-bronze (once the small S.Turkey tin deposits became too expensive), while copper minerals often form together with arsenic minerals (indeed, copper-arsenic sulphide and relatives are still significant copper ores to this day) so smelting of poorly-sorted ore would naturally produce an arsenic bronze.
You need to be *more* careful working with this stuff. But it's often the correct material to compare with for experimental archaeology. But you're already quite careful.
I understand that bronze swords were used as stabbing weapons but if I had a sword and saw a stab coming I would try to deflect it with my sword. I wonder how many bronze on bronze sword duels a sword would survive before having to be melted and reforged.
As an Aerospace machinist, I really loved watching this 👍
As a hotel receptionist, I also loved watching this.
I think having a proper steel axe as a baseline comparision would have really helped putting these results into perspective.
Except for the original users, 5000-odd years ago, the comparison would have been with a "proper flint axe" because there was no such thing as "steel" to cast and forge.
@@a.karley4672 And I get that. On the question: "Why didn't people in the past just use steel?" It's because they had to figure out the technology to manufacture it in the first place, so mostly furnace and forge construction. And even then comparing modern high-grade steel to anything historical isn't quite fair, since even medieval steel was far different in quality. So I guess in conclusion, modern steel is quite the miracle and it's performance is really a marvel, we shouldn't take it for granted, and in the past people were wonderfully creative to make due with the things they had available.
@@rhonin255 ISTR a comment a while back that "traditional" wrought iron work (principally decorative, that-century) effectively died in the mid-1970s because modern steels were too tough to work, compared to crucible steel, alloy steels etc. 98% the same composition ; vastly different properties.
You satisfied a curiosity that I have always had about Bronze tools and their resilience and strength. Great job.
An appleseed edge is another term for a convex edge, where there's no discernible edge bevel as the edge is blended cleanly to its apex.
… So he didn’t give it an “appleseed” edge?

Just like to say a thank you as I've been a viewer for some time and I really appreciate the time you spend explaining things that may be obvious to other metal workers and done without patronizing us viewers who may not be as knolagable.
You should mold in the "welding bars" into the top surface, so when you pour it, it won't just run off...but pool into a nice formed rod
Either way...such an incredible design and build!

Thank you for your video. For those who are unfamiliar with sand casting, the top half of the mold flask frame is called the "Cope", the bottom half of the mold flask frame is called the "Drag", and the sand packing tool is called the "Rammer".

I had to smile at your comment that "I am sort of a perfectionist" That is certainly obvious by just watching you work, and also looking at your foundry. I salute you!! Dr. George Whitehead
Blown away with how awesome your skills are. I was expecting you to make fairly basic axes for testing or whatever. Wish I had your skill.

@@Shadrach666 Because I have seen a lot of casting videos that featured failed castings because they refused to do the basics despite being foundrymen, smartass.
I am a physician and know nothing about metallurgy, but your work looks absolutely beautiful.
Did you know that the most common version of aluminum bronze is called Nordic Gold? Nordic Gold is what the .10€, .20€ & the .50€ coins are made of. They choose that metal because it does not contain any metals that people would have a contact reaction with.
So, non-poisoned money. For the opposite approach see the Larry Niven short story "The Roentgen Standard" for money that discourages hoarding.
I'm glad you made a follow up video! I absolutely love these axes. Such beauties.
I like your organized and clean style of manufacturing !
I am impressed. Your craftsmanship is high level.
I actually really like how these look! The more orangey color looks really good with the tan of the wood! And that hammered edge is just an awesome finishing touch
5:04 You can observe a similar effect by dropping a broomstick vertically on the ground repeatedly. The wood grain at the end of the broomstick compacts and the broomstick starts to bounce higher and higher with each drop.
As a casual observer, those casting molds and the results were incredibly impressive.

Your attention to detail stands out. Your skills are self evident. Your voice overs are appreciated. You tell us what you're doing and why? Well done Sir 👏
I read a graph somewhere that tin bronze, after work hardening exeeds the hardness of mild steel so honestly it would make for an excellent hatchet edge. If you have any interest in history tou might find a ton of inspiration in how strong bronze appears in historical writing... they made cannons out of the stuff for example.
Yup high grade Tin/Bronze has higher hardness than low grade steel, however it has a lower melting point (and a much lower point that it loses strength and fails)
👍
tool steel still cheaper
Great video thru and thru! What a wonderful blend of woodworking and metallurgy. The casting process was great, reminded me of freshman mfg processes class in college. I think the additional heft from the higher-density tin bronze help the hatchet function slightly better by removing bigger chips per chop. Maybe not as sharp and strong as steel, but much better corrosion resistance.
The difference in colour is a restult of the krystalline lattice forming differently, since it cooled faster, causing their atoms to allign differently.
The colour would become uniform, if you heated it up, and then cool it down again (Tempering).
Depending on how hot you make it, and how fast you cool it you alter the properties of the metal quite drastically.
It will make it softer or harder, depending on how much you heat it, and how quickly you cool it down again.
Quick cooling will make it Hard and Brittle, slow cooling will result in it becming Soft and Ductile.
If you are proficient in tempering, you can make the edge hard, while keeping the core and body soft, which will cause your axe to hold an edge for longer, and prevent it from chipping easily.
I know how to do this with pretty much any Steel, but that one i am not familiar with.
You can test it by casting or forging rods, then heat them and cool them differently and see the results by seeing how much the bend before breaking, and how much force it takes.
This however requires specialised equipmen, but there is shops who wil gladly test these for you for a fee.
also you can look it up, there have been tests on this very material, and the results should be publically available.
Thats for iron alloys, not copper alloys, iirc it also dont work with most other alloys ether
Copper and copper alloys will just go soft if you heat them regardless of how fast or slow you cool i down.
That's why you have to work harden copper and bronze if you want it hard.
When working copper you get it to red heat & quench in water to soften- the opposite of how iron works.
@@simonmorris-p7m It's called Annealing
Thank you for your video and it was so beautiful to watch you casting , forging ,, making the handles and your narration

how about bismuth bronze or black bronze? im always interested to see how different alloys perform
Bismuth bronze?
@@just_that_crazy5179 bronze of the bismuth variety, if i remember correctly it's an alloy of bismuth (obviously), zinc and copper and it looks neat, but i don't know how durable it is.
@@Minty1337its mostly a self lubrecating alloy
Their are basically infinite versions of bronze some work as expected some do something compleatly unexpected
Black bronze looks neet but is 8% silver and 8% gold so get expensive quickly
@@aggese only 8% silver doesn't seem too bad, but the gold is a bit ouch.
yea its weird how easily copper seems to 'bond' with other metals and produce funky alloys, and they all got such unique colors and properties too, far more fun than steel alloys in my opinion.
There is another ancient bronze that was used that you want to stay away from even though it is actually pretty good, Arsenical Bronze. Arsenical Bronze contains between 1% and 12% Arsenic (yes a Toxic Heavy Metal), with the rest Copper (and sometimes Tin), making this stuff can cause serious health problems and even death. A number of Copper Ores contain significant amounts of Arsenic (Enargite, Olivenite and Tennantite), likely the first accidentally discovered alloy and type of bronze, but due to the improved characteristics it was likely deliberately manufactured fairly quickly. Highly levels of Copper and Arsenic were discovered in Ötzi's hair (Ötzi, The Iceman, is a 3000+ year old (Chalcolithic, Copper Age) natural mummy found in ice along the Austria-Italy border), suggesting he was involved copper smelting and that they were using some of these copper/arsenic ores.
I set up and operated a non ferrous foundry in the 1990s. Though I did not work with aluminum bronze, I seem to remember reading the strength of this alloy is approaching the strength of mild steel. I most worked with brass, german silver and silicon bronze. BTW, it was a lovely job in winter, LP gas fired furnace kept us so warm!
In early bronze age you would have more likely found arsenical bronze.
It's mechanical charateristics are comparable to tin bronze, but it's not industrially made, and a DIY would be pretty dangerous, for obvious reasons.
I recall that arsenic bronze kind of happens by itself. The arsenic is present when the copper ore is mined. You have to purify the copper to avoid getting bronze.
Guess I’m not going to sleep now
Same
The handles you made are gorgeous, and the colour of bronze is so lovely
You should do a razor next. Romans were clean shaven with large round bronze razors with work hardened edges. Since then we switched to carbon steel and sharpening, but I’ve always wondered how bronze would perform!
Bronze is also anti-microbial, which explains how Roman surgeons were able to perform complicated surgeries without antibiotics - their scalpels and other instruments were all made of bronze !
Probably comparable as far as use goes. Even though steel is harder, that comes into play only in edge retention properties, meaning steel holds its edge longer before resharpening is required.
That said a bronze shaving knife would be badass and I would totally buy one if available. Bronze is so beautiful.
True! Something that people don't think so much about is how we actually had "shaving sharp" blades in antiquity. Not everybody was walking around with grizzled beards and crudely-cut hair, and it's not like the Romans had genetic factors giving them boyish faces. The middle and upper classes had access to some properly razor-sharp blades for a baby's-butt-smooth shave.
@@zimzoboh yeah copper is toxic to bacteria
I wondered some time ago, how Romans achieved being beard free.
Your moulding skills are impressive. Thanks for the video.
FWIW, I own a Phosphor Bronze hatchet cast by a local gunsmith twenty years or so ago. It's amazingly tough.
Well done. Adequate camerawork. Suitable audio. Well narrated. Thumbs up.
I had cast a few bronze swords (just for fun) and they do not like chopping. I lack the set-up to cast them very thin, but the thick swords end up bending and twisting while chopping. This makes me want to cast a tin bronze axe now. I even have a spare axe handle... hmm.
I remember hearing about how Greek soldiers used to have to pound their swords back into shape during a skirmish, so maybe your not too far off with this..
@@edgeldine3499i think that may be a reference to Gaulish warriors using iron swords, which would have been what we call “wrought iron,” but it’s plausible that similar issues might be had with varying qualities of bronze available before modern scientific metallurgical knowledge. Often bronze swords were not made with full tangs, to save cost, and the blade would be riveted to the handle. These rivets were subject to breakage especially with slashing attacks, so bronze was often limited to short thrusting swords, arrowheads, and spearheads. Many of these short swords would only be sharpened at the point, the sides were left dull.
The ancient Greeks also used a bronze sword with an incurving blade, called a _kopis_ , likely derived from the earlier Egyptian scythe-like _kopesh_ .Hammering the edge of the blade causes the metal to expand along the length of the blade as it is made thinner; this pushes against the C-shaped blade, which keeps the metal under compression and increases its hardness without becoming brittle. There was also a double edged pattern described as a “leaf shape”, which had incurving sides, taking advantage of this compression principle to allow sharp edges for slashing. When iron started to replace bronze, they would be made in the same patterns, until smiths learned how to take advantage of the different properties it afforded . This can be observed in the early versions of the Roman _gladius_ with its “narrow-waisted” appearance.
@@edgeldine3499 After twenty minutes both commanders step forward and shout "Stop! Hammer Time!"
Absolutely beautiful work, pure art. Excellent video as well. Truly a gem!
The weld wasn't contaminated, the filler wire was when you poured it onto the casting sand
The sand contains oil, so that makes sense.
@@misterhat5823 if you have a tig brush or even brake cleaner you should be able to avoid future contamination
Really nice hatchets . Keep up the great videos and comparing metal contents versus strength . Great video .
One note, you've made metal axe that looks like a metal axe, but in Ancient times for quite a long time they made metal axes that look like stone axes, with huge bulbous convex edges that were basically indestructible. It took a long time for the form to adapt to the material properties.
Not so - the earliest Bronze Age axes were diminutive and gracile. During the Chalcolithic they quickly evolved into gracile types - and the sheer cost and difficulty of extracting and melting enough metal to make an axe means they were small. If you held original early axes in hand, you would see they are much smaller than you imagine - often smaller than a man's hand, narrow butt and thin. That's why they used relatively large wooden handles, to add weight for cutting.
Wicked awesome axes. The contrast between the handle and the axe heads is very nice. Especially with the hammered edge look. 😎👍
Bronze is a fantastic material for tools and weapons. The reason it was ditched for iron when humanity moved to the Iron Age, wasn’t primarily because iron was superior in. performance, but because it was everywhere, and it was cheap. The only reason it wasn’t used prior to that was that no one had figured out how to work it.
No its because they figured out steel. Which is harder stronger and can hold an edge far better than bronze.
@@davidpowers9178
That’s part of it, but most of it is because of logistics. Most of warfare comes down to logistics frankly.
Bronze was a good material but relied upon massive trade networks and cooperation between empires. The moment iron working became readily accessible, it destabilized the entire political ecosystem. For the first time, even small nations could afford to equip armies with high quality arms and armor. The massive advantage that rich nations had enjoyed for millennia evaporated over the course of a century or two, and only a couple of them survived into the new era, and them, significantly diminished.
@@davidpowers9178steel wasn’t really in use until the Middle Ages - smiths in India developed a technique of hammering carbon (from the charcoal fuel in the forge) into iron, producing small pucks of steel called “wootz.” Somehow this knowledge reached Sweden, presumably through the far-ranging trade contacts of the Varangians, who also served as Imperial guards at Constantinople, and there smiths learned to pattern weld these pucks into swords made with steel, superior to anything else in Europe at the time, giving the Vikings an edge over the competition thus enabling them to conquer much of Europe, Russia, and the lands around the Mediterranean .
Sir, those are things of beauty! You are a talented fellow and no mistake!
Im surprised youre surprised bronze axes work. You know in my langauge the word for bronze is vara meaning force/power cos in the bronze age those who had bronze and not stone had the stuff.
There really was no such thing as a bronze or stone age. Some people had more advanced things. And people with stone tools continued until this day.
@@joshportie We define the ages based on what the most advanced thing is.
Man ...the hammered edges look AMAZING !
you shouldnt compare them to iron or steel,you compare them to rock axes...that are horrible to work with,a giant leap for humanity
Bronze is still quite good compared to iron and steel. In fact it’s better than a lot of iron and steel, just not as good as specific types of steel
I'd be interested to see how they compare to the non sparking tools of today. Beryllium Copper is what is used now and it's dust is toxic from what I understand. I cast my own aluminum bronze axe head about 10 years ago, but never got this far because I made the eye way undersized. It was clunky
That's some of the cleanest casting i've ever seen!
Very attractive looking axes! I love all the technology information, but can we just marvel at your craftsmanship for a minute!
I absolutely love the slight rose red color on the tin axe, it looks absolutely stunning.
Oh hey a Vegas TH-camr? And of something that i enjoy too. This video was pretty neat. And yeah 8:12 haha we don't really have anything to test an axe on any trees that don't exist going outside the city limits. Got to travel far north in Nevada to find any real woodlands.

I still have my Norland ax. My mom bought me for backpacking when I was 13. Same design great for packing and wearing on your belt.
Great video! I handled a bronze sword blade I believe 3000 years old from the Middle East. It was in amazing condition and the edge was still sharp. I have never underestimated bronze tools and weapons ever since. I was living near UNGH (university of North Carolina) a few years ago and there was a book in their library that showed details of hundreds of bronze weapons.
This would be the ultimate material for making acoustic drums. Aluminum rings like a bell and bronze has a lower register but is super cutting and excites the room.
On another channel (Metatron) a medieval and ancient warfare/history enthusiast was discussing how bronze was a lot tougher than most modern people give it credit for, stating that bronze weapons were still serviceable options for ancient warriors and people thousands of years ago, even with the introduction of iron weapons. They would not have had access to machines and pure ores but you just proved to me at least that our ancestors, using tin bronze, would have had wicked edged tools and weapons of bronze. Really enjoyed this. Thank you.
These are awesome. And they’re probably even better than they seem here because the other end of the wood wasn’t supported, so the movement likely took a lot of energy out of your hits
Wow those are gorgeous. Bronze is such a nice looking metal.
Copper and aluminum both conduct heat extremely well. Copper also changes color on its surface with heat, due to oxidation, depending on how hot it got. When you TIG welded, you made a hot spot. The heat spreads outward, very quickly. Once the copper gets hot enough to oxidize, it will. Just around the TIG weld, the IG controls oxidation, but once the heat gets outside of the inert gas, it oxidizes.
Lovely workmanship indeed!
Those hatchets are gorgeous 🤩
Love how you blend three d printing with old techniques
You are an artist. Great work.
Its amazing how much a few % difference can change the final outcome.
Its even worse than that some alloys are none inuative in hiw they behave and even hard to predict with modern science
@aggese it really is a art. Ratios, temperature, cooling rate, cooling time, reheating and tempering among others can all cause vastly different outcomes.
Excellent workmanship they are perfect good job

Beautiful work! I would have been intrigued to see how tough they were against steel, but that would have been destructive.
A lovely job you've done with these. A couple of small points about the hafting of your heads. Hickory is a good choice, however when you choose your wood for the handle, the grain should run in line with the length (about 90 deg from what you have). this will lessen the likelihood of you splitting the length of your handle on impact. Additionally, there is no reason to use the metal wedges, they will add nothing to the holding. Some would argue that by splitting your (wood) wedge, that you have now actually weakened the hold of your wedge. These are just "fine points". I don't want to detract from your very fine work here.
Good work, man. Having a steeper angle for the edge makes it a bit "duller" in cutting wood but it will hold better.
Beautiful. Very nice work. You have a talent.
Neat 📸 I'm a sucker for bronze age tools and weapons. Tin bronze can be a lot stronger than you'd expect.
