I've watched casting videos for 5-6 years now. The fact that you showed (and explained) what didn't work, in addition to what did work, makes this one of the best casting videos I've seen. When I have a specific shape I want to cast, it really helps to see what other people have done for venting and pouring locations in their mold design. Learning what doesn't work is just as important as learning what does work, and you covered it wonderfully.
the cool thing about needing brass is, when you are done at the range i go to, there is usually tons of other peoples brass as well! freeebeeee! always leave with more than you came with ;)
You know what. We see all these "Its so easy to cast aluminium, Brass e.t.c" videos and they do make it look SO easy. Its GREAT to see you fail (I dont mean that in a negative way) and your processes into making it successful. A WHOLE lot more realistic and helpful...IMHO.
Well done lad. Thompson is a wealth of GOOD type info. The only changes I made were to add a bunch of stainless wool to the sand,plaster mix for extra toughness. Thanks friend ! ! !
Peter!! I've watched you on flite test for forever but I never thought to look for your channel. It seems like you have a slight gun addiction just as I do. Love it, man love it. Keep up the good work!
oh definite luck with the basic sand/foam evap casting! still good a very good lesson. next up, go for wax and investment plaster. fairly soupy with vibration will get bubbles out, for really complete bubble elimination you'll want to whip up a vacuum bell (can be done with a coffee can for smaller projects!). you can get BOTH actions (vibration and vacuum) out of a decent size strong aquarium air pump by sealing its seams and giving it an air intake tube, to pull a little vacuum in the can while vibrating everything in it.. mount air pump solid to your board with seal (for the upside down big coffee can), board's feet are thick foam rubber stuff so whole thing vibrates same time as it's pulling air out of the investment plaster inside the smaller soup or coffee can, with the BIG coffee can as vacuum bell. hope you get the image of what I'm typing here, this is a very low budget low tech good working vibe table vacuum bell, you can get nearer jewelry castings out of it. it'll typically take 20-30 minutes vibe-vacuum time for the bubbles to rise up out of the plaster in first part of it's way to drying. if you get the picture do it, it'll really surprise you!
I once worked in a foundry as a sand molder. Outlet holes are important to let the air out and to also gauge when its full. You can also poke small holes evenly throughout the sand mold and spray C02 into those holes to harden the sand to a solid mold, this would help with detail. I really enjoyed that work, casting is amazing.
I love it. 3:57 (how fitting right?) "But before that, let's go to the range and get some brass". I subscribed to your channel immediately following that.
Really like this video, fun to watch the process you went with the trial and error, much more interesting than just seeing you get it right the first time.
I tried something like this with a smaller forge and turned random old tools I had laying around but I had the same problem with heat. The forge just wouldn't get hot enough. Thanks for the idea buddy
I'm surprised that you don't have More subscribers than you got right now. You are very skilled and I love watching your videos! 500k subs in 2017? Keep it going :)
Liked the video, you covered a lot of detail with minimal words or time. There's something about working molten metals that reminds me of sitting around a camp fire. Almost feels natural. Try using wax instead of foam, might be surprised.
Next time, have the sprue stick out of the sand and put a tin can around it. This causes the metal to form head pressure (and keeps it from flowing out on to your bucket) which forms the part better . It also gives a large mass of metal to allow shrinkage without causing voids in the mold when the metal cools.
Hey Peter you'll get better but here's a few tips and I'll be sure to upload some videos of me casting when I get better. When you put your foam in, don't make the sand so damp (judging by the color of the sand) and it always helps me to put it through a kitchen strainer to kind of make it less coarse. Lastly, foam coolers make the best forms and melts away the best in my experience
I used my 3d printer to make a replica of the final object that needed to be cast for someone, and they were able to make some sort of resin mold from that, which you could pour the brass into. The result needed some cleaning but it was still a pretty efficient way of doing it.
Peter, I have been wondering why you weren't in any new flighttest videos. Glad to see you are doing your own thing! I'm excited to catch up on your channel and looking forward to the future of your channel. Thanks for sharing your creativity with the world. - Stanford
Tip for lost PLA casting. Use plaster paris instead of sand. You'll get a finer detail. bake the plaster mold in an oven at 350*+ F upside down with a tray at the bottom for at least 6 hours, 24 hours at 300* is more ideal. This it to bake out all the water so the mold won't crack or explode when you pour a cast. Upside down, to drain the PLA (good habit stemming from lost wax casting). Once poured and ready to break it out, dunk the whole plaster block in a lot of cold water. This will shock the plaster and shatter in the water, making it easier to get at the piece.
I've done the hole metal casting thing with this kind of forge but I haven't done the gas conversion yet but when I do it if it gets better results I'll make sure to do another comment as an explanation of what I did but basically when you go to remake the donut put metal wires in it to increase the durability of it and when you do the forge again put a steel almost outer crucible with a welded bottom going into the floor of the bucket which will also increase the longevity of it
Where did you get the crucible, how long does the furnace last? Can you scale the the furnace up? What temperatures can you reach in the furnace? I think I would like to duplicate this process. Great channel, I think I see where you are going with this. This looks like fun!
good job on the little glory-hole. another tidbit investment casting, after plaster good and dry, bake them up couple hundred degrees helps flow into small stuff. the molten not cooling and clogging before a fill.
I'm a reloader and I have a bunch of brass that has approached its life span and I was wondering what the possibilities are for melting that brass and turning it back into new production shell cases.
I'm seriously impressed. I didn't think your furnace could get hot enough for brass; how did you regulate the temperature so you didn't cook off the zinc? Myself, I was lucky enough to find a bag of refractory cement in a local home improvement place, so when I put mine together it'll last quite a while. EDIT: Also, use a steel bucket instead of a plastic one.
I'm sure someone else has probably said this already but it's not a forge, it's a foundry or furnace. Other than that awesome job. that gives me hope for making my own.

Honestly, your channel is one of the best channels I've found.
Agreed i subbed for all the random quality videos glad he shows the fails too, in a way he reminds me of peter brown with more tech
SkyAviationHD Agree
I second that!
This IS the best channel on TH-cam I was with u at 8k Peter. Keep up the good work man.
SkyAviationHD I
You NEED more viewers man.
Stupid TH-cam algorithm.
#burnthealgarithm
Lol
the cool thing about needing brass is, when you are done at the range i go to, there is usually tons of other peoples brass as well! freeebeeee! always leave with more than you came with ;)
haha, funnything is that the last shooters left 100+ rounds of spent 556, I didn't even shoot more than 50 rounds!
i love u even more peter. after the range scene!
Best way to get your own brass. So happy I subbed.
RIP Grant
You will always be remembered
Yes
Ganesh Neelagandan ummm what now?
Mr Hernandez what do you mean
Ganesh Neelagandan did he pass?
@@dutchman55 unfortunately yes
Best. way. to. get. brass. ever!!!!
funnything is that the last people left 100+ rounds of spent 556! I didn't need to shoot much at all!
PeterSripol
Brass for days!!!
Did you press the spent primers out first?
Love it when I go to the range and there are hundreds of brass casings lying around. Love it.
Erik Jensen a lot of primers are brass so he might not have had to
You know what. We see all these "Its so easy to cast aluminium, Brass e.t.c" videos and they do make it look SO easy.
Its GREAT to see you fail (I dont mean that in a negative way) and your processes into making it successful. A WHOLE lot more realistic and helpful...IMHO.
Love the style at the beginning of the video! Really lightens the mood
Well done lad. Thompson is a wealth of GOOD type info. The only changes I made were to add a bunch of stainless wool to the sand,plaster mix for extra toughness. Thanks friend ! ! !
Another great video. It's gratifying to see that young people still do the kind of crazy stuff that I did when I was young.
hes such an amazing engineer .. i love to see his every vid
I LOVED that short clip of emptying the revolver brass onto the camera
belt buckle... just saying...
Peter!! I've watched you on flite test for forever but I never thought to look for your channel. It seems like you have a slight gun addiction just as I do. Love it, man love it. Keep up the good work!
Great music as always! Love your videos
Peter you deserve at a million subscribers! Keep up the good work!😉
yes he does a good job
I like that you showed the failures. Let us avoid those issues!
dang! I never realized Peter was packin so much heat!
Enjoying the Videos and the pretty chill community , keep up the entertaining inventions and what ever else is in your future
Back from the range...awesome sauce!
Ur very courageous, creative n a Riot! Getting free spent brass, urs or others
at the range is also great. Thx!
The best Art Deco themed build channel!
I absolutely love the editing style and your sense of humor. Great work. Keep it up!
This isnt forging it's casting or founding, forging is when you stamp hot metal into a shape, the thing you melted it in is a furnace
title updated! I'm an idiot haha, it shows what I know! :D

Try to make a spaceship

You can also poke small holes evenly throughout the sand mold and spray C02 into those holes to harden the sand to a solid mold, this would help with detail.

I thought forging was the process of moving heated metal around/shaping it
I love it. 3:57 (how fitting right?) "But before that, let's go to the range and get some brass". I subscribed to your channel immediately following that.
Really like this video, fun to watch the process you went with the trial and error, much more interesting than just seeing you get it right the first time.
You are brilliant. I am hopelessly wasting my life. I want to create and innovate as you do.
Nice video, I like that you showed what you tried and what ended up working
YESS, the one channel I actually check for uploads everyday. New video is like Christmas.
thanks man! :D you guys all watching keeps me making more vids! I just need to get back on schedule.
PeterSripol a schedule? that's even better. keep it up man! :)
Nice Beretta I have a 90-two and I love it!!
I'm really looking forward to that thing you said near the end of the video! (about casting 3d printed parts!)
This is THE best outro on TH-cam!
thanks mate! awesome to see someone that actually posts up the stuff-ups so we can learn.
It's really cool that you showed all the failure modes
You should do a workshop tour. or show us what your favorite tools are.
I enjoyed your stuff on Test Flight. Love you went out on your own to try some other projects. keep up the great work!
Great edit, and well paced! Liked the music and funny bits too!
This has to be one of my favorite videos you have done!
I tried something like this with a smaller forge and turned random old tools I had laying around but I had the same problem with heat. The forge just wouldn't get hot enough. Thanks for the idea buddy
I always find his editing very clean and smooth as well as amusing it is
I love your channel Peter. I watched you on flight test and it's great to see you doing your own thing.
this channel deserves more subs
the effort you put into your end sequence is what separates your from other youtubers
This guy teach us that we must never give up and keep try...
Good effort Peter. Good luck with the parts you trying to make. Looks like a fun project.
I'm surprised that you don't have More subscribers than you got right now. You are very skilled and I love watching your videos! 500k subs in 2017? Keep it going :)
*HI* this is the best channel I have ever found
fantastic video Peter. looking forward to more. you really did a good job.
it feels nice that one of my favourite youtuber watches one of my favourite youtubers videos
Need to watch more of your stuff Peter, specifically the followup video to this one. I do like your collabs with William Osman too.
Dudes... hilariously entertaining video.😆 Nice shop, and nice music.
looks like grant imahara when at the shooting range
Nothing more to say than, AWESOME!
Very nice.... keep up the good work. tech stuff is good and the editing is awesome.
I love the way you "get brass"
xD
Also appreciate you posting where you hit pitfalls.
Out-friggin-standing stuff Peter.
Please make a store! The only planes I like on the ft store are your design. I would love to support you directly. Thanks so much!
thanks for posting your failed attemps so i don't have to make the same misstakes

will do! I've even seen some 3D printable waxes!

This causes the metal to form head pressure (and keeps it from flowing out on to your bucket) which forms the part better . It also gives a large mass of metal to allow shrinkage without causing voids in the mold when the metal cools.
That is excellent work, Peter. Nice job!
best youtube channel definately
Really darn interesting video. Great job Peter!
I hate that you left flite test but I'm super happy to see you are doing good and have your own channel that is also doing very well
The slightly moist sand made me nervous when you were pouring the brass in, but I'm glad it worked well. Can't wait to see what else you do!
weird huh! :D spill a bit of it on concrete and it explodes all over the place... damp sand and not so much!
Glad to see a real American channel
Nice work. Thanks for also explaining your failed attempts.
Awesome yet again Peter!!
This actually turned out realrly good
Hey Peter you'll get better but here's a few tips and I'll be sure to upload some videos of me casting when I get better.

infinitely better than that king of random guy could ever hope to achieve since you know what you're doing

PeterSripol you genius ...!
Kinda amazing you got it this well on your first attempt
Loved seeing the king of randoms forge design being made by someone else. Ive made a few things from his channel and wondered if anyone else had
Loctite 565 is what you want for plumbing Peter. BTW Nice choice of "brass separator" tool.
Peter, I have been wondering why you weren't in any new flighttest videos. Glad to see you are doing your own thing! I'm excited to catch up on your channel and looking forward to the future of your channel. Thanks for sharing your creativity with the world. - Stanford

my lids kept braking too. we made 2 before giving up on it and just used pavers which would get brittle after a few uses but they were ok
Love your AR-15 Pete!
I really like your creations! Keep it up.
Where did you get the crucible, how long does the furnace last? Can you scale the the furnace up? What temperatures can you reach in the furnace? I think I would like to duplicate this process. Great channel, I think I see where you are going with this. This looks like fun!
This is how you can make scratch built steam engines. Nice vid, packing will help with limiting flow distortion.
Great video Peter. Def something different. Hope you had a great New Year.....peace
Damn good for your first try peter
To make the plaster of Paris last longer when it was still wet you could of reinforced it with steel wool
yes, or stacking small grid steel wire mesh through it.
Going to try this for the next one!
good job on the little glory-hole. another tidbit investment casting, after plaster good and dry, bake them up couple hundred degrees helps flow into small stuff. the molten not cooling and clogging before a fill.
Should check out markforged 3d printers. They print with multiple different metals. One of them even have a forge inside of it.
I'm a reloader and I have a bunch of brass that has approached its life span and I was wondering what the possibilities are for melting that brass and turning it back into new production shell cases.
I really like the way you shoot your videos.
Hey peter I've been subed for a long time you have inspired me now i have started building models 🙂
I'm seriously impressed. I didn't think your furnace could get hot enough for brass; how did you regulate the temperature so you didn't cook off the zinc? Myself, I was lucky enough to find a bag of refractory cement in a local home improvement place, so when I put mine together it'll last quite a while. EDIT: Also, use a steel bucket instead of a plastic one.
Clickspring did a good video on sand casting for a grip device. If you are thinking about casting a screw, you'll want reliefs for each blade.
Dude, you're crazy! I found your channel by accident and I love it. :D
FLYING CAR PART 2 I SM DYING PETER!
its coming its coming! :D need more time for engine experimentation!
That turned out awesome:)
I'm sure someone else has probably said this already but it's not a forge, it's a foundry or furnace. Other than that awesome job. that gives me hope for making my own.
