Beautiful steak and knives. I like the look of both knives. The wood pattern in the knife gives it character that others don’t. The mirror finish on the other is lovely and brings out the color nicely.
lots of valuable information, thanks! Tried recreating this myself with some variations. Cut the template out of styrofoam, no real sprue, just made the handle a bit longer. Loosely buried the styrofoam part in some (coarse) bird sand. Surface finish was meh + few small imperfections that went a bit deeper, but I just made the part thicker to compensate/grind away later. still have to sharpen + make a handle for it. maybe it was just luck, but seeing that my cheap and dirty no-effort lost foam cast worked at all made me forget about getting a proper sandcasting setup in the foreseeable future, lol captured all details in the styrofoam, even those I hoped it wouldn’t capture
Hey brother just a tip: you can epoxy your pins before installing them as well, it may help your knife hold together. Also sand the pins a little with 220 grit to rough them up. It gives more surface area for the epoxy to bind to :) Love and peace, beautiful work! Thanks for sharing!
Love your work! looking forward to try my hand at casting bronze myself. You're an inspiration for me. You should post on other social media to connect with like-minded artists. Your work is worth millions of views! :) have a great year. Appreciation from India!
All in here - wishing you good luck and gods speed. Years ago I tried three metal pours using 3 different bronze alloys to make a 1 pound figurine. Silicon bronze, phosher copper and I can't remember the 3rd alloy. My results were an orange peel gold colored as cast finish wtih the silicon bornze, and a super smooth almost requiring no finish bronze color with the phosper bronze. A lower than ideal poor temperature may have partially contributed to the orange peel finish on the SB. What really amazed me though was the nearly perfectly smooth as cast finish of the phosper bronze. Apparently a small almout of phosherous makes melt more fluid thereby giving a smooth as cast finish.
@@lundgrenbronzestudios Not sure of exact formula but i think a good diy substitute may be 85/15 copper/tin plus phoshper/copper shot thrown in at the end. I do remember an old time foundry guy gave me a small ziplock bag of the shot. Word of caution though -use a seperate crucible for silicon and phosper bronzes. Found out that the hard way as my next batch was contaminated badly -pretty ugly metal (lead and silcone dont mix, i think). If you ever do contaminate a batch, not to worry though as bad batch "cleans" your crucible for the next melt. In hindsight, on the good smooth pour, I may have used too much shot and unknowinly compromised strength for looks -never did test for strength. This PB alloy may work best with simple patterns with no parting lines -just cast and done!
That alloy may be able to harden due to stress or machining. Bending and similar operations may also harden it. I doubt that any het treatment will harden it but heating to a high temprature for a while probably makes it softer. I may be wrong here and this is a special alloy and metal manuals should be consulted. According to an old ASME HBK your alloy will become very hard and very strong after two different heat treatments and ended with quenching in water. The properties are comparable to some steel.
I think both knives look great, but the one with the oak pattern is awesome. I made a cast Iron bonze a good while back, a little different formula than what you used, but I have never made anything with it, it probably needs to be remelted and mixed again as it wasn't perfect on the mix, a friend gave me the percentages and I said I wanted to try it, I believe he made a couple different mixes. Maybe I'll try again soon.
@@lundgrenbronzestudios I tried 70-25-10, which was one formula(CU-FE-AL), seen the guy that gave my friend the formula use 80-8-12(CU-FE-AL) I want to try formula #2 as he cast a axe head and it looked pretty good.
@@lundgrenbronzestudios honestly I cannot remember, been a while when I did it, think I melted the copper then added the aluminum, mixed and then added the iron. I would have to go watch my video again to verify.
Nice work. I'm very interested in the cast iron bronze alloy. Have you measured how much HRC this bronze has? How hard it is compared to, let's say, steel hammers, pickaxes etc.? Or compared to other bronzes and copper-based alloys? I know beryllium bronze is used to make sparkless tools, slightly exceeding 40HRC. Speaking about hardening, bronzes are prone to work-hardening, and bronze khopesh or bronze-age sword edges were hammered to make them harder, leaving the rest of the blade unhardened and tough. Next time maybe you should try work-hardening. Or, if you have the propper equipment, it could be nice to try to forge it.
Hey man im 19 and just starting to get into metal work I built my own forge and want to make some bronze knives for my family for gifts. Any help or tips would be much appreciated

The as-cast surface finish is fantastic. Al-bronze can be difficult to cast so your gating, temp, pouring, etc. was spot on --congrats.
That’s good to know!
I learn something new every time I watch your videos. Nice work!
Now you need to make a bronze fork for the set!
😆 that’s a great idea!
I greatly enjoy watching you’re content, please continue to share your projects. 😊✨
Thank you for watching!

Good job! I have never tried lost foam casting.
Excellent work! I'd like to see more stuff made from aluminum bronze!

The wood grain gives it a pattern-welded look. Great video. Edit: and the steak looks very tasty!
not really
beautiful work! interesting experiment. i think you made the right choice

Thank you! I didn’t realize I had viewers all the way in India!
Wow! They turned out amazing!
Thank you!
That wood grain one looks awesome bro! Almost as good as that steak
It was a good steak.

Interesting. I have a piece of scrap phosphorous bronze, I’ll have to keep that in mind for when I use it for a melt.

I like the wood grain knife better. Has a bit of rustic appeal to it.

What was the formula you tried?

Was there a specific order of melt you used? I added the aluminum last but I also had a lot of dross form when I did.

They both look awesome, my favourite is the blank one, how are they doing now 8 months later??
They have not tarnished and still look great. I only use them on special occasions though. So not too often.
Sure would like to see your alloy as the center of a katana.
It’s a wonderful steak knife.

Dip in oil instead that should help with the warping
How about casting a scale model Vought F4U Corsair
Looks like test temper was. Over aged cause of brittleness non ferrous metals get hard on temper and not as much on quenched depending on metals
Good job brother, but the "handles" are called "SCALES", on a knife. just sayin:) Keep up the good work.
👍
@lundgrenbronzestudios how has your steak knife held up? Have you been regularly using it for food? Has it gone through the dish washer, etc?
I haven’t used it regularly. It’s more of just a show piece.
That's just a knife.
It’s a bronze steak knife!
