Adopt the one hour rule for your shop. No welding, burning, heating anything for one hour before you leave. Check all plugged in devices, soldering irons etc., gas valves and sniff for smoke, and store those propane cylinders outside before you walk out. Fire is a very real thing and easily started. In my 44 years of shop work I've encountered several unintended fire situations. Great video.
Great project! I liked seeing the multiple attempts and techniques to make it happen. I’ve recently tried making some of my own bronze castings, largely due to this TH-cam channel. I just made a small silicone bronze knife and was pretty happy with how it turned out.
Man that turned out great! Crazy how much that steel tube expanded! I would be really interested to see how well that wax resin works with ceramic shell. I printed a whole bunch of stuff to invest with Suspendaslurry, but then I read that it cracks ceramic shell during the burn out, so I got discouraged.. I'll probably still try though. I was thinking of just drilling a bunch of tiny drainage holes in the shell before burnout and patch them afterwards. Keep em comin! I hope this video does really well for you.
It does seem to expand a lot. I find a lot of cracks even in the investment. However the last few pieces I had issues like that were solid and I’m thinking a hollow print might allow for expansion without cracking the investment. This resin doesn’t seem to melt out as much as it just burns away, so I’m not sure drainage holes would work but I’d be curious to see how it would work.
We have had a ton of problems with that resin and suspendaslury! We went through about a dozen castings. I'm currently 2 days into a hollow print to see how that works.
@@HawkWorley100% of the time, print hollow when possible. There's no need to have it filled, you can add wax in if you want after, but for the print, hollow is better. Just remember to plug the holes after curing and drying lol
Nicely done ❤❤❤ I've a friend wanting me to make them a ritual dagger, thinking to use the mill to engrave the blade and shape it, then use investment casting to make the handle, and just pern over some bar rods to join it all together, not fully decided yet, lot depends on the friends final design choice, which I'm still waiting on.
Wow the knife looks very cool that's a lot of work to make it metal when the Freeman supposedly made theirs out of a tooth of a worm which I suppose would involve carving rather than casting
My first cast knife came out great ( purely by accident) but about 2 inches short. I ground and polished it into an acceptable knife. Cast a next attempt to gain the 2 inches maybe 4 times. Only gained an inch ( plus a thicker bolster and butt cap.) was able to braze a few inclusions. Sort of worked. Your casting experience gives me some ideas to try next round working up to a sword. Makes me marvel about the Bronze Age talents. To make a fine knife requires some fine tools as well.
The metal should be a bit hotter and the mold can be preheated with torch. When you make testing and vary settings, modify only one parameter at a time to find out the true response.
Like use a 1/4" width strip of some kind of hard alloy plate steel to act as the cutting edge of the knife and just incorporate the plate into the mold and pour molten silicon bronze around it to create a decorative and functional blade?
Since this is just a show piece I didn’t want to deal with the blade warping or hitting the wrong spot so I decided to skip the peening but if I want to make a battle ready blade I will be sure to add the peen.
print without supports. printers have a native setting to detect beams and speedup and stretch the ooze. the hole in the handle is so small it could have printed without support

Nice piece you cast there. Thanks for showing the other attempts that didn't quite work, I learn a ton from your channel.
Crysknife. That prop is on the top of my list of props! Yours turned out great!
Thats right attitude, failure is even learning. Its a process like life itself. Really cool Dune knife!
Congratulations on this new project! 👍I hope you were able to sell it at a fair price considering the price of the alloy and the resin.
That turned out looking really good!
Good Job! Lots of detail in this one too!
I know right
I hope your channel gets more popular. You deserve much more thab you got.

Oh I’ve made a number of blades and every time I am even more amazed amazed by the examples history has to show us.
Great video
Nice work! Blades are tricky and pretty much every casting video where they make a blade has a million failures.
tree supports, trust me. best choice/change ever
That really is an interesting sword. You worked hard and kept at it. Good for you! I really learn a lot from all of your videos!
I prefer the Dune from the early 00's, but this was fun to watch.
Tanning booth! Thats great, ha ha.
Gotta think outside the box.
The metal should be a bit hotter and the mold can be preheated with torch. When you make testing and vary settings, modify only one parameter at a time to find out the true response.
I think you are right the metal was too cold.
I think the main issue was that you chose a really hard shape. Real bronze blades usually have a "thick part" which I guess helps with the flow.
Yeah it was a thin blade.
The taning booth caught be off guard
😂 gotta have fun with it.
Very nice!
Great video. How much casting sand did this project take? Thank you.
Oh no! Thy knife chipped and shattered at the tip ;-) Just kidding of course, really nice piece!!!
You put so much work in it, it must cost 2000 bucks 😂
Very cool! Would casting it in two different parts, handle and blade then weld them together work better?
You could do that but it would take a lot of work to blend the weld into the piece so it didn’t look like a weld.
Very cool! Who's or where did the 3d file come from? Might want to try something like this myself.
I don’t remember where I found this file. I know it wasn’t thingaverse.
Would you be able to cast a knife like this but out of silicon bronze but cast most of the blade around a sheet of tool steel for the edge?
Like use a 1/4" width strip of some kind of hard alloy plate steel to act as the cutting edge of the knife and just incorporate the plate into the mold and pour molten silicon bronze around it to create a decorative and functional blade?
You could do that but it’s not going to weld together so there would be a seem between the bronze and the steel.
You got me on that one!!!
+1Like & Sub & share....
Good work, keep melting, you're good!!!
Cheers from France, Beard on, Bro !!!!
Ok…take my money, seriously. how much to make me one and ship it to the uk?
Dang
Can i buy a few dozen?
Haha. No I make it for fun I’m not set up for profit.
Remember to peen or work harden the cutting edges. Looks good!
Since this is just a show piece I didn’t want to deal with the blade warping or hitting the wrong spot so I decided to skip the peening but if I want to make a battle ready blade I will be sure to add the peen.
heyooooo
Hey! 👋

I am watching with pleasure. Please tell me what material of the crucible you use. The graphite crucible burns out quickly. I am very grateful to you
