Aluminum FGC 9 Project - Part 1

[@jackknifesociety7154]

I saw a guy use rebar for his barrel material and use the "bathtub" rifling technique and it worked perfectly for him

[@amphoravideo]

definitely worth considering. Thanks!

[@zVoiddd]

@@amphoravideo you can bore a barrel out of an old steel bolt or rebar or something with a drill and a vise , and you can make a rifling button with a Dremel and a piece of old drill bit that you harden in your kiln. Refer to theIdahoanshow for more in depth detail it was his idea.

[@Arch-e2v]

@@zVoiddd you can also just bore to around 5mm or so and use ECM, reduces the need for expensive equipement like rifling buttons and dies

[@DanielMendoza-vz6ss]

If it ends up working out I hope you will post the revised files somewhere.

[@amphoravideo]

I'd love to but Uncle Sam gets grumpy about that. My understanding is that you can have it....you just can't share it. I might be able to post everything other than the lower receiver. I'm looking into it.

[@DanielMendoza-vz6ss]

@@amphoravideo do you not live in the USA? If you dk publishing files is legal here. It's covered by the first amendment. Cody Wilson made sure of that in court. The files themselves are not illegal. It's the having or giving out/selling physical copies of the parts without being a gun dealer.

[@amphoravideo]

I 100% agree but the the current resident of the white house has a different view of that. It's possible but I'm looking into it a bit more before inviting too much trouble.

@@amphoravideo In the book "That Every Man Be Armed", it explains under your constitutional rights that you are allowed to make your own weapons AND you can share the information on how to. What you can't do is sell the home crafted weapon. Just think of it as how all those gunsmithing books have been sold (Even on Amazon), which would be no different to what you are doing. Just as long as you're not selling a built version of the weapon to someone.

[@tritech]

"post apocalyptic" hydraulic tubing would still be available. Don't skimp on your health.

[@taitruong4018]

I'm actually doing this right now, but for the upper. Also did this for the bolt drilling jig and welding jig because the pla ones just weren't cutting it

[@sweetgumnyc7794]

any update on this? i was thinking it would be fun to try something similar but instead of metal, i was thinking of making a silicone mold of the 3d prints, and casting in a much higher quality resin material. smooth on sells some really high performance resins that have much higher strength and heat tolerance compared to 3d filiment. btw, were you planning on releasing your edited files? check out a metal called zamac. its basically an alumunim / zinc ally thats pretty strong, low shrinkage and lower melting point compared to aluminum. i was able to melt it on my stove with the help of a torch.

[@amphoravideo]

Unfortunately, KZbin deleted my updates. Too frightening for their tender eyes. Lol. Yes, I managed to cast an upper, lower, front & rear. Definitely usable but not as aesthetically pleasing as I’d like. I’m starting over using a Saturn S resin printer which produces MUCH better prints. It’s amazing. I recently upgraded my kiln by adding a programmable controller which has improved my quality. I plan to try casting it with ceramic shell casting soon. I’m pretty excited 😊 Using a Silicon mold is an interesting idea. They do tolerate high temperature’s pretty well. Seems like it might work. Good luck!!

[@ISpillSprite]

@@amphoravideoglad to hear the project was a success! Is it possible to upload the. Videos that were removed to another platform like Odysee? I’d love to see an in depth video about your processes and the finished results, including your next attempt!

[@DireAvenger001]

@@amphoravideohey what the other guy said. Could you please upload the videos to the Odd Sea or another gun friendly platform? Been following this and the ABS FGC for awhile

[@royyaboyy]

Any where we can find updates on this since KZbin is full of sissy's

[@SkilzGamerz]

Can you maybe share the process somewhere else with us or a guide. So we can make this

[@catverpasha]

please make it possible to download

[@darkshock42mlg05]

For the barrel donor the same as yhe. Last one or buy a m barrel blank.

[@LukeVorstenbosch]

Do you please share the new 3d drawings ?

[@ЮрийАблицов]

Hi, how much were the parts reduced (how were the thicknesses for the castings calculated)?

[@doctordapp]

Have you tried natriumsilicat (Na2SiO3) in plaster instead of water?

[@catverpasha]

can you give me the files of the aluminium one?

[@ndpredator4726]

I was wondering if people have done something like this and make the fgc out of metal

[@vidaemp]

I'm doing it this way, I made a base piece on the 3D printer, I made a mold of this person and I'm making wax copies, and then these copies go to another mood and I put it to dry in the oven at home, to melt the wax, and with the mold dry and with the wax melted, this mold goes into the oven that I made with an air conditioning gas cylinder and refractory bricks that I made watching a video here on KZbin, if you want to learn how to make this low-cost oven, just browse here by "FORNO DE FUNDIÇÃO CASEIRO"the video is in Portuguese, but watching it is not difficult to do the same

[@vidaemp]

where can i get the files to make this weapon? I already have the oven and now I want to modify this designer and make one for myself

[@amphoravideo]

I’m honestly not sure where to currently find the files.

[@DireAvenger001]

Lost PLA method?

[@amphoravideo]

Yes, but this filament is specifically designed for casting. It burns out flawlessly.

[@kirilandreev7145]

@@amphoravideo You can use concentrated NaOH or KOH solution at 50-70 degree celsius to dissolve the PLA without need to burn it out. Plain transparrent PLA works best, or use red color to easily identify ane undissolved remnants. At 60C a piece of 1.75mm PLA filament dissolves in less than 3 hours in NaOH solution. Need to 3D print hollow or with minimal infill, and provide flow through the part using some pump. 5W aquarium water pump would do. Can coat the part with heat resistant silicone, which might allow for casting multiple parts. This will do for ZAMAK 2 or other Zinc alloys, but might not work for aluminum since temperature is too hight for most silicone. However, there is one that can withstand 1200 degree C and should work, but is brittle and will not allow repetitive use. In my opinion casting in Zinc alloy is better, since it flows way better than aluminum, has roughly same strength, and casts in much lower temperature. Didn't tested this yet to make any part, but I did dissolved PLA this way and cast Zing in silicone years ago, so it will work. Remember to dry the mould in kitchen oven 2-3 hours at max temp before casting and wear glasses.

[@kylejahnke9095]

Any updates on this?

[@amphoravideo]

Well....there WAS an update until KZbin decided that it was just completely unacceptable and pulled it down. I don't think it actually violated anything but I suppose aluminum frightens them. Basically, I successfully cast an upper, lower, front, and back but they weren't as aesthetically pleasing as I'd like. I've now upgraded to a resin printer and have added programmable controllers to my kiln and furnace. So, my technology and understanding of the process are greatly improved and I'm planning to re-cast them soon. I'll try to post a new video...being careful not to terrify the fragile ones who monitor this stuff. lol

[@brucehirsch5437]

Update?

[@michaelkocher7103]

What did you scale it by?

[@amphoravideo]

I scaled it up by 1.5%

[@marcgeronimo2997]

Why on earth did you make an ABS FGC-9?

[@amphoravideo]

Because it’s more durable than pla and has a higher glass transition point. It’s a superior material but it’s much harder to work with.

[@joselinares4899]

Ive been wanting to do that for some time, just missing the burn out oven (expensive). How are you going to bypass this process?

[@amphoravideo]

Short answer is that I use a kiln. Longer version is... I bought a very old electric kiln dirt cheap from Craigslist. I removed the top half and used it to make a small melting furnace. The bottom half is now a half-height kiln...which is PERFECT for burning out.

[@amphoravideo]

@@GriefGrumbleTheMauler Interesting. I'm going to have to investigate the wax model scenario.

[@amphoravideo]

@@GriefGrumbleTheMauler wow.... that's a lot of good info. thanks. much appreciated

[@pinhead1304]

dont cast a barrel unless you want to die. go and read about pressures. a gun is very close to being a bomb. you couldn't shoot through a barrel made of mild steel safely with smokeless powder. let alone anything else.,

[@amphoravideo]

Your warning has great merit. Oddly, I once had a rifle (7.62 x 39) explode when I took it to the range for the first time. It was dramatic. Aim. Breathe. Squeeze. Bang. I stood frozen looking down range through the sites for several seconds thinking "something's wrong" before I slowly looked over and saw blood flowing from my arm. I did not enjoy the hospital visit. 20 years later, I still have small pieces of steel in my arm so, yep...the risks are serious. I'm more cautious in practice than I probably seem. There's a lot more science to casting than it seems on the surface. If I do eventually go down that road, it would involve much research and care...and remote testing.
