Punished Props Academy is there any way that in a two part mold you could cold cast? And if you have multiple peices of the gun how would you recommend molding it?

[@level52studios61]

Thank you guys so much for the help on that project! It was for a gift for Bungie and they loved, even had it out on display at GuardianCon, SO COOL!!!

Great video guys, thanks for posting this!

Thanks so much, gang! =D

[@admiraloom]

This is so nice to watch, thank you. Btw we are developing an online makerspace solution over at youblob.com, perhaps you wanna repost this video with a step by step guide and include the products that you use? That would be very helpful. PS we are still in beta release, plus it is built on top of an open marketplace, so you can sell your own stuff :) And if Smooth-on decides to join as well, they get traceability on each recipe that is made around their products :D

[@brunonogueira9353]

Punished Props Academy Please a fully cured resin will bonded to another layer of PUR resin? If i wait to much time to close the molding and put more resin the parts can not welding well? Thanks

[@dfcprops3849]

Sweet! Appreciate all the time and effort Punished Props Academy puts into each video. Molding and casting is something I'd really love to do sometime, but it's rather time consuming and I want to do it right. Your videos have definitely made the process less intimidating!

[@IconicProps]

Love your stuff. One way for you to make a little better barrel mold/cleaner barrel hole is to put a metal pin into the gun. Sticking out half an inch at least. Leave the pin in the gun for both sides of the silicone pour as if its part of the gun. Once you are done with the mold, you can place the pin back into the mold. Put mold release on it. Once the prop is done pull out the pin, and you will have a perfect barrel, and you dont have to worry about any bubbles in the barrel. (which is the main reason you would use pins, the second being for places where your hole would bond both sides of the mold or tear easily during replication. For anyone watching, not only does the baby powder allow for the resin to flow into the tighter areas, it more importantly allows for the air bubbles to escape. It creates a friction free surface for the bubbles to bounce off of while traversing up (out) of the mold, past the incoming resin. Great tutorial. Mason

[@mykalimba]

If I correctly understand the technique you're describing, that would leave a perfectly cylindrical barrel hole in the molded piece, right? What if the barrel hole actually has geometry (like rifling, etc.) as the piece in this video has (see 2:05)?

[@sleepinghermit7778]

Nice to see how to make a two piece mould but where is the challenge as it is a straight forward project. Looking to see if you can help as I have an awkward model and what you have done has gave a little insight but what i am making is a lot more intrigue and was looking for help

[@hellyeah8784]

Is that Okay you did 2 times pouring. Will the 1st resin stick well with the 2nd? This trick help for high detail mold.

Hi Bill, Nice jobs you have there. I follow all your lessons. Thank you Why so many keys on the molds? When I make it I put not so many. Is that importante? Thanks aagain and keep on the very good work Cheers Antonio (Portugal)

[@punishedprops]

As far as I know, you can't have too many registration keys in a mold like this, so you might as well put them on every available surface.

Awesome video guys. Should I use Sulfur free HARD clay, or MEDIUM? Thanks!

[@punishedprops]

I personally prefer a more medium clay.

[@panoramix3192]

@@punishedprops I saw you guys used the EM-217. It doesn't say the level of hardness it is, but if it's what you guys used, then I'm gonna order that same one. It comes in 50lbs bags and that's a lot of clay for my project, but it's quite inexpensive. I just don't know if it's sulfur free, but if it didn't react negatively with your silicone it shouldn't with the Polytek I'm using. Thanks so much!

[@WarlockOfWiFi]

Loved the video. Do you have any estimates on the cost of the mold and cost of the resin used? Just curious on it. Loved the video. Thanks for always making great content!

[@punishedprops]

I would guess we ended up using ~$50-$60 worth of silicone on this mold.

[@darkshadowsx5949]

that's a lot better method than casting silicone around the part and cutting the mold in half to free the part.

[@Archaon6044]

Hey peeps, I'm trying to make a silicone mold to copy some warhammer pieces (strictly for personal use as basing materials). The masters are large, flat, thin, regular rectangles, with lots of small details on the upper surface. I'm using Smooth-On's Oomoo 30, 2-part silicone rubber. The problem I'm having is when I pour the silicon, it's not flowing in to all the fine detail in the master and air is getting trapped, so the final mold has lots off missing or obscured details. I don't have access to a vacuum chamber, and I don't think that bubbles in the silicone is the problem. What I need is some way to help the silicon flow better I think. Any pointers or advice would be greatly appreciated

[@Sunders]

painting video soon? great tutorial!

I didn't get a casting of the pistol yet, but once I do I'll see if I can do a painting video.

[@JohnnyMonsterson]

That was really nice! Questions: How do you clean the mold after use? And What can I use as an alternative release agent? Would vaseline or baby oil work? Thank you!

[@punishedprops]

If the mold needs cleaning I'll wipe it down with rubbing alcohol. I wouldn't recommend using any kind of mold release other than what's recommended for silicone. Ease Release 200 is fantastic.

how much temperature range silicone mold can withstand? I am about thinking to use this material for plastic injection.

[@JohnSTF72]

Could this be used to cast metal objects or just resin and plastic? Nice video by the way.

[@punishedprops]

There are only a couple of low temp metals that would work in a silicone mold, like pewter. Although that much molten pewter would probably destroy a mold like this.

[@supernova8604]

Black armory is out and an exotic sniper came with it. Its called Izanagi's Burden. Do you guys mind making it?

[@zanlan79]

Do you have any recommendations for the degassing chamber? Like how long to leave the silicone in there for, what pressure to set the vacuum at? Thanks!

[@punishedprops]

It depends on the silicone, but you typically leave it until the silicone bubbles up and then settles again

Fantastic video! Question: can an actual handgun be used without harm to the item? I make leather holsters and have need for casts or unusual items that can only be cast from the original gun, or gun & scope/light. Thanks.

[@punishedprops]

Theoretically yes, the silicone shouldn't adhere to the metal. You'd just want to make sure you have any open cavities blocked up with clay before molding, and I imagine you'll need to do a pretty thorough cleaning after the fact.

[@mikefreeman3772]

[@mml3140]

If you intend to use Chrome on a prop like this. Would you 2k clear coat the master. Or the casts that come out ? I'm thinking if done before you can just cast and chrome right away.

[@punishedprops]

Doing a clear coat like that before making the mold will certainly help with your surface quality, but you'd still want to lay down a gloss black layer before chroming.

[@DragonElf66]

The other way you could measure how much silicone you need is to put the box on a scale then zero it, then fill it with water. The weight of the water is equal to the amount of silicone you need in fl oz.

[@paulodepablo3649]

This pistol mold reminds me of Trigun.

[@Vancy_And_Andy]

How do you clean up any left over resin residue in your mixing/pouring containers? Or are they throwaways when you're done?

[@stealthflower]

I can’t answer for the guys, of course, but I have some tiny moulds that I fill with any leftovers, then make fridge magnets with them as add on gifts for friends/customers/random people on the street. If you look on AliExpress or eBay for silicon ice cube moulds, you can find some great shapes for a couple of dollars.

[@punishedprops]

You can usually pull the resin out of these cups once it's cured and then wipe out any residue.

[@Dragonknight_props]

good friend, what is the mix gray you use to make the prop? sorry my bad english

[@punishedprops]

That's a urethane resin. Links to the products we used are in the video description.

[@mitchellradspinner4491]

7:30 When you flip over the half poured half of the mold/cast how ginger do you need to be to prevent the semi-cured part falling out of the mold?

[@punishedprops]

There's actually a decently strong bond between the silicone and the resin - an airtight seal, essentially. If you don't jostle it too much it should be fine to flip and place on the other half, provided you've let it cure long enough to be tacky.

[@shitstickstomyass]
