How to Make 2 Part Molds using Oyumaru, No Resin, DIY Clay Push Molds

How to Make 2 Part Molds using Oyumaru, No Resin DIY Casting
It is so frustrating when an action figure doesn’t come with enough weapons (or worse, the weapons are a non removable, molded part of the holster). Or how about when your Pokemon Ash figure only has one standard Pokeball? Well, now you can learn how to duplicate your existing small accessories to give to your other figures a larger weapon arsenal or with a bit of paint, Ash can finally upgrade to Great or Ultra Balls.
This video will explain how to use Oyumaru to make one part and two part clay push molds that can be filled with your choice of epoxy based clay. After the items are removed from the mold, they can be sanded and painted.
The materials I’ll be using in this DIY 2 Part Mold Making tutorial are:
-a pot to heat water in
-thermometer: amzn.to/2rNNsPo (Amazon affiliate link)
-2 Part epoxy clay: I’m using Apoxie sculpt: amzn.to/2qTBfZh (Amazon affiliate link), but you can use other brands like Milliput too: amzn.to/2rQXXAw (Amazon affiliate link),
-For making the molds, I use this version of Oyumaru: amzn.to/2rryq1w (Amazon affiliate link) Or you could get a two pack of Oyumaru: amzn.to/2pUfHe1 (Amazon affiliate link)
The Instructions I was given for using Oyumaru are:
Heat Oyumaru for 3 minutes in hot water (176 degrees F or 80 degrees C)
Wipe Oyumaru dry with paper towel
Make mold and let it sit for 5-10 minutes before using
The items I used in the mold in the video are Hasbro’s Marvel Legend’s Deadpool’s pistols and Tomy’s Pokemon Ash Pokeball, but you can use whatever small accessories you want.

I hope this video is helpful! The links to where you can purchase the supplies used in this video are in the video's description.

[@mrrictus]

Another impressive vid as always . As an alternative mold making product , take a look at composimold.com/mold-making-putty.html You melt in in a microwave before use, and afterwards pour over the item you want to make a mold of.

[@Zubbie]

+Swoldier_Boi Thanks! That ComposiMold material sounds interesting and I like that you can use it with resin. Have you had a chance to work with it?

[@thatcomicguy4333]

Zubbie can to use this for venom slime/ooze

[@mrrictus]

Zubbie unfortunately I have not used it yet. But it is sold at the craft store in my area. I wanted to run through my supply of amazing mold putty, and oomoo 25 that I recently purchased. And video showed up in my subscriptions this morning of a craft artist using it. I will send you the link.

[@mrrictus]

LOL I just noticed that you mentioned dollar tree gloves. I picked up a pair 2 weeks ago and have not used them yet. Now I know the quality lol

[@Rafu_Aeru]

Big Greenie: "I am the unsung hero in all this." Oyumaru: "Hold my mold."

[@johnnasta]

This is basically the same thing as Blue Stuff. You can buy it on Amazon. Here's a tip: Cut the bars into cubes and they will soften faster. You can also use any 2 part epoxy putty to make your duplicates. It doesn't have to be the expensive artsy kind.

[@JohnnyLeyenda]

Unlimited parts for my wargaming armies! Thank you kindly for the video! (as a stupid side note, thanks for giving celsius degrees as well, saves a few seconds of searching and converthing from °F)

[@natsu2010]

I've seen other trying this and I am amazed with this! There are parts I want to mod and re'create. Like weapons for toys that don't fit other toys or figures and easily mold, recast and mod then mold and recast again.

[@xscaped]

Very cool. I just ordered this type of Oyumaru, so I can create molds, too. It is great that Oyumaru is reusable. So the investment is not bad.

[@crudivor]

Love the background music. Thanks for the cool video

[@mdwms6152]

good tutorial w helpful hints - GREAT music!

[@boneshaman8912]

where the hell was this stuff in the 90s when me and my gamming buddies were in to kit bashing miniatures. we could have save a tone of money by just making copies of the original ones and remanufacture parts that got broke or lost.

[@Burnt_clutch89]

I know it has been a few years since you posted this video. But if you ever need to translate Japanese Google's lens app translates things very well. I'm pretty sure it can be downloaded onto all Android phones but comes stock on Google phones. It has saved my life building Japanese model cars.

[@janraymondjulian1273]

you are the answer to my prayer for the lost parts of my figures

[@LegitStopmotions]

Unlimited weapons

[@Zubbie]

Yep!

[@mohdshukur5276]

Right..

[@libbyblue62]

For larger projects I strongly recommend composimold. Pretty much exactly like this but you microwave it and you can get it in large quantities.

[@pangeagamer7223]

Thanks for the tip, definitely will help me tremendously with my idea

[@austinrouse5301]

Very informative! You don't see many videos regarding this matter. I've been trying to find videos to duplicate bits for warhammer, and not butcher them and most of the molds are either off or too brittle. Also great you put the links to the Japanese mold! Saved a big headache, keep up the vids I enjoy your work!

[@Zubbie]

Thanks! And I'm glad I could help 😃

[@shimmyjimmy7642]

I don't know why it makes me laugh, but I like stumbling onto a video and instantly knowing it's Zubbie haha

[@lv2xlr8NOW]

Thank you for explaining the temperature part. I watched a video with blue stuff ordered it and was unhappy with results it never became soft as your show in your video. Thanks

[@Zubbie]

Glad I could help!

[@allthatjazz4437]

YAAAAS! I know must've been a hard one, but I'm so happy you got it out, nice job! there's just not enough guns, but now I can have gun racks and armorys!

[@Zubbie]

Glad to hear this video is helpful! Yeah, the editing of this video wasn't fun. haha. I think because it's so long, my video editing software decided it would be fun to mess with me by randomly flipping clips upside down, deleting tracks, and other really weird stuff. Or maybe my laptop is to blame. I think I got all fixed though.

[@allthatjazz4437]

Zubbie yeah, I never would've noticed anything had gone wrong. But that might be my bad observation skills...

[@EricSpeaksOut]

This is so useful! I was just looking for a way to duplicate the X-Men logo for a figure. Love your videos!

[@Zubbie]

Glad I could help! :-D

[@ReconFigures]

Cool stuff, Zubbie! I need to find some of that stuff for the molds. I'm sure there's plenty of things I can cast or even create with that. And I love your videos! Even if something doesn't come out perfect the first time, you still include that in the video. All part of the process!

[@Zubbie]

You can get some of the Oyumaru on Amazon with free shipping. I like the clear version and the link to that variation is in the video description. Glad to hear you're enjoying my videos! I figure if I include some of my mistakes, everyone can learn what not to do. lol

[@keycelive5927]

I always watch u so i can do this stuff for my little brother

[@Zubbie]

That's so nice of you to make things for your little brother! I bet he loves it. 😊

[@keycelive5927]

Zubbie he does but i learned from the best aka u but i dont post it

[@kurosgaming2329]

im gonna make so much stuff! power! unlimited! POWER!!!!!

[@Zubbie]

ALL THE STUFF!!!! :-D

[@UserID_Hidden]

You actually did pretty good with the pronunciation 😉👍

[@mindseyemelodies]

Great video! It always helps to be able to make duplicates of your accessories.

[@Zubbie]

Thanks! My Marvel Legends don't have enough handguns to go around, so now I can just make more. :-)

[@nocturnenoble2468]

Thank you so much for the tutorial!

[@hipzilla702]

I need to try this again!

[@Fig_Fury]

thanks for sharing. im alwats on the look out for cheaper ways to supply my black series and legend figs with more weapons. Thanks again!

[@Zubbie]

You're welcome! Glad I could help :-D

[@jacobtothe2112]

It's called the "trigger guard."

[@madrabiddog]

This is super helpful! Thank you!

[@ayeletkuellar72]

Thanks this is going to help give my transformers more weapons

[@habanerojones2169]

Oh man this brings back memories. Professor Oak giving you your first Pokemon and two guns. #pokemonredpokemonblue

[@Natureisrestless]

what a cute voice!

[@henrydelay1821]

simp

[@JoeXTheXJuggalo1]

I know this is a old video but I do have some spare tips for you. Tip 1: use Blue Stuff by Green Stuff World. It's the same thing as that Japanese product. Tip 2: cut the mold sticks up in small cubes because it softens faster. Tip 3: form the first mold half and let it cure up. Than once it has cured soften up the rest of you mold material and press it against the cured half of the mold. It helps a bit whenvits time to pull the mold apart.

[@nathanwang4700]

Thanks Zubbie, this vid really helped me out.

[@Zubbie]

Glad to hear that! 😃

[@nohemigg95]

Thank you!! This is the kind of video I was looking for 😯

[@ReflexologyFTW]

+2 for that Gelatinous Cube reference LOLOL. :D

[@Zubbie]

Glad you enjoyed that joke 😆 I think you and I are the only ones! haha

[@BigJon808]

Sweet!! I need to do this!! Mahaloz for sharing!

[@Zubbie]

You're welcome!

[@rabidhammer31]

Badass vid Zubbie! Great directions and always dig the classical music = )

[@Zubbie]

Thanks Rabid!

[@TheHelado36]

You have a beautiful voice ! Thanks for the video !

[@spidiq8]

If you buy boxes, (typically 100 in a box), you can buy them in varying sizes, S, M and L, I'd guess those are L which the filling stations and shops sell in smaller packets as a one size fits all. You can select between Latex, (which fit really closely but fall apart near solvent), or Nitrile which aren't as flexible for fit but harder wearing.

[@Zubbie]

Thanks for the info!

[@pangeagamer7223]

The curve around the trigger is the trigger guard 👍

[@tomasbcs]

Great video, i wanted to make some sort of Punisher hideout diorama and need lots of guns, this will come in very handy!

[@Zubbie]

That's a great use for this! That way you don't have to sacrifice the guns your figures came with for gluing on a weapon rack.

[@arafatjunior9402]

Nice Tutorial But I wonder if I want to make a clear part which item i could use? Thank

[@AnthonyFilms29]

Yes I finally get to cast the dc-17’s :)

[@jurassicwars]

Karma Productions and now 2 years later, it’s my turn

[@EricSpeaksOut]

I hope you come back and make content again soon 😌

[@davidlagunafernandez6476]

Yo he usado esa técnica también, y es pura lotería que te salgan las piezas bien por las dos caras. Por mi experiencia para conseguir resultados aceptables es mejor hacer primero la cara inferior y cuando seque esta añadirle la cara superior. Yo utilizo masilla epoxid del proveedor asiático por 1,20 euros y el resultado es el mismo que con masillas mejores o más caras.

[@rockbuildaz7115]

cool stuff, thanks for sharing.

[@Zubbie]

You're welcome! And I appreciate you taking the time to comment :-)

[@sheridanburrows8394]

Great work. Thanks for ideas.

[@yaboijjonah._.1815]

Zubbie I love your channel so much

[@Zubbie]

Thanks so much! :-D

[@bimarusela2607]

very helpful tutorial awesome

[@Damixn-mu9kq]

can you please do a video about how to making Wolverine claws

[@tralifcustoms6823]

Do u have alternatives instead of using epoxy clay?? those are stiff and easy to break

[@lisachau2298]

I wonder it can use for plastic models. Just want to know if it is that's all.

[@NefertitiJonesaw]

I like the Oyumaru. Very inexpensive and I really like that it is reusable.

[@Zubbie]

I'm really impressed with it! It's easy to use and if you mess up, just throw it back in the water to reheat it.

[@AnneAndersonFoxiepaws]

Do you think this would work for making a mould of a leg and hoof of a horse model? I have the original horse and also a broken one so I thought I would attempt to make a mould of the intact limb and use wire to reinforce the join after I cast the leg? I decided that I will go ahead and try this as I have everything I need and I will reinforce the join as I said with wire superglue and baking soda for a good hard join. I think I will use milliput. I have a couple of bags of thermoplastic beads which I found were cheaper to buy.

[@Arkie80]

The curvy thing that goes around the trigger is the trigger guard.

[@LeonEdwinsHeart]

Very nice!

[@Zubbie]

Thanks!

[@ahnafmahmudzareef160]

Sister how do you made this are they unbreakble

[@wewyllenium]

Hi. How rigid or tough is that putty? Are the outputs really hard?

[@maxramirez1517]

I like your nails

[@noah_james]

Video idea: Have you ever considered making Web Wings (or Armpit Webs) for Marvel Legends Spider-Man out of cloth or thin plastic? Just an idea. Love your channel! :D

[@Zubbie]

Glad you're enjoying my channel and thanks for the suggestion!

[@abeeshek123]

this was comparatively very easy process u hv shown here Zubbie !!! loved it and thanks for sharing my Hawkeye :) btw, hv u tried re producing any marvel legends head sculpt with it. pls try it if u can, that will be amazing !!! extra head, hand, peg joints always helps customizers :D

[@Zubbie]

That's so funny you mention head sculpts! I've already picked out some to giving it a try. I think it should work, as long as I don't sand off the nose or something. xD

[@abeeshek123]

lol !!! best of luck...i am sure it will work out very well !!! btw, any other alternatives u can think of for that material ??? coz sadly...import of it is taking its 11$ price mark to obnoxious 40$ !!! :@ :( :(

[@Zubbie]

Geez, that's quite a price hike. Someone else said that it looked similar to a product called Blue Stuff.

[@abeeshek123]

thanks, will check that out...cheers !!!

[@t-.-t.]

Hey its on hobbylink japan. Its only for 150/- rs. Im getting one

[@darrentinman6994]

Would this work with resins? I would like to make a 2 part mold to use with a resin which i would only need to use a few times and i don't want to go out and buy mold making kit which would work out way more expensive (if i make a poor mold)

[@marcosbetancourt358]

I love your videos

[@babettedaynorowicz7734]

Oh it is just like "Friendly Plastic"

[@jeffreytorres3268]

this is actually awesome. Might give that a try and hopefully it goes better than the hoodie I did (might need to redo it btw x).

[@Zubbie]

Things don't always turn out the way I picture them in my head too. You just have to keep trying and learn from your mistakes. :-)

[@jeffreytorres3268]

+Zubbie so true. thank goodness u didn't see it when I tagged you in it on IG.

[@Zubbie]

Yeah, I don't remember seeing it. I'm sorry I missed your tag!

[@jeffreytorres3268]

Zubbie it's ok

[@DanielS2001]

I know this may seem like an odd thing to suggest, but if you haven't tried it yet, you should try Oogoo. Basically, it's a DIY Sugru that's a mix of clear silicone (from the hardware store) and corn starch that can be made into sort of a moldible and flexible putty. You can even color it by adding in acrylic paint while you're mixing everything. May be useful for a future project. May tutorials on KZbin and Instructibles about it: kzbin.info?search_query=Oogoo

[@Zubbie]

That looks interesting. Thank you for sharing!

[@DanielS2001]

Zubbie You're welcome. :D

[@MistCellaneous-5]

Earlier this year I tried making a two-part mold with this and for some weird reason the second part of the mold completely fused with the opposite mold. Does that mean I have to put something on top like oil or water to prevent it from sticking?

[@Zubbie]

I didn't put anything on top of either half of my mold to prevent sticking. That's really strange they stuck together for you. The only thing I can think of why that may have happened is the second half was still really hot when the two were joined and melted the first half a bit. Maybe you'd have better luck if the second half cools down a bit longer before placing it on top of the first? Hope that helps! 🙂

[@buzzlightyear3214]

Thanks just ordered the stuff from Amazon, but my question is, is tge sculp good quality and strong enough to use for weapons or is a polyuethaan better, grt from the Netherlands, thanks for the video.

[@bentalls85]

This has probably been asked to death before so sorry beforehand. Can someone tell me if you buy 2 or 3 packs and them combine em while they are hot to make larger parts say like a throne for 6 inch figures etc?

[@My_wife_left_me]

Hey children today we will be learning about wacky fun world of clay molding sponsored by skill share

[@topanoi]

thanks zubbie

[@Zubbie]

You're welcome 😃

[@Flackooooo]

Zubbie do u know how to duplicate translucent accessories?

[@kanadakanadakanada]

Hi, is that material still a little flexible after cooling down ?

[@Transforming_Skyscraper]

Very cool! Have you ever heard of Plasti-make? Similar product, I wouldn't have thought to use it for mold casting. I will now!

[@Zubbie]

I haven't tried Plasti-make, but I've tried Instamorph, which I think is similar with little plastic pellets. I didn't have much luck with making anything out of it though.

[@aukiejohnson4308]

this is great

[@Zubbie]

Glad you liked it!

[@justghost8713]

good stuff

[@babettedaynorowicz7734]

Apoxie Sculpt, You can also use Magic Sculpt

[@Zubbie]

I haven't tried Magic Sculpt before, but that's good to hear it would work too. Thanks for letting me know!

[@babettedaynorowicz7734]

Surething :)

[@marcosbetancourt358]

nice video

[@jacksimpson2857]

please make a running effwct

[@TheNightBadger]

So this is the Japanese version of 'Blue Stuff'? They seem the same to me. Is it possible to cast in certain colours? I wanted to cast some weapons in gold but without painting them, and I've been having a hell of a time with resin colouring.

[@suprastevio2264]

How durable is the epoxy clay you used?

[@keithkatzz]

Can there be any other clay that I can use instead of oyumaru

[@Zubbie]

Other people have mentioned that the Oyumaru is similar to a product called Blue Stuff so that should work too. Silicone also works well for making molds, but you cannot reuse it. The important thing is that the product you use to make the mold needs to remain flexible so you can remove the items from it.

[@poppyappletree1400]

It baffles me that Americans don't own electric kettles.

[@matthewgagnon9426]

Americans by and large don't drink tea, so we have less need to have a special kettle solely for boiling water.

[@libbyblue62]

I do drink tea often...but I just keep a teapot on the stove on a back burner. No need to take up extra space and spend extra money on a glorified teapot.

[@redsand210]

We do ;). Fancy coffee

[@stoneagearcher3477]

I have one, just used it!

[@drvivekmallan]

Why aren't you making vids anymore gurl?

[@richardthehutt4407]

Have you looked into making silicone molds and using liquid plastic for casting?

[@Zubbie]

The silicone I saw at the store was not reusable and it would become kinda pricey if you want to make a bunch of different molds. I don't think I've heard of liquid plastic though. Are there any particular brands of it that you've tried or heard about?

[@richardthehutt4407]

The silicone can't be reused to make new molds, but you can use it to make the same things multiple times (especially if you use mold release spray). I've not been able to try any of them, yet, as I'm on a very thin budget, but I've seen a lot of instructional videos, here, on YT, and most tend to favor Oomoo silicone, and Polytek Easyflo 60 plastic. I will link... www.amazon.com/dp/B004BNF3TK/_encoding=UTF8?coliid=I1VKK8672TH1FF&colid=1FWITMELR8CC2 www.amazon.com/dp/B00OKX5FIK/_encoding=UTF8?coliid=I10HARI6WDWJLP&colid=1FWITMELR8CC2

[@Zubbie]

Thanks for the information Richard! I'll have to look into those products. :-)

[@ralphrenteria1149]

I saw a similar technique but they used glue gun sticks, also so do the scoops you use come with the apoxie scuplt

[@Zubbie]

No scoops are included, but that would have been a good idea. The scoops I use are just part of a teaspoon set from the dollar store.

[@benjaminsmith2367]

It look like this material is similar to blue stuff.

[@Zubbie]

Oh, it could be. I haven't tried blue stuff before.

[@juanvillegas8455]

What paint or spray do you reccomend for the guns?? (:

[@Zubbie]

I'm just going to use cheap acrylic craft paint, but any acrylic paint should be fine.

[@MalakaiSchuhart]

its a desert eagle chrome spray paint acrylic black grip

[@mrguzman0513]

Is there other colors for apoxie clay like brown or gun-metal color?

[@mrguzman0513]

Or better question when I make that ball off apoxie clay and decide to dip it in paint then put it in the cast will it be ruined?

[@DRWblessyourface]

I really want to make a Logan movie figure but I don't have any other wolverine figure and that means No claws to use for my custom :c cant find any video of how to make them. Any advice Zubbie?

[@Zubbie]

I haven't tried making claws, but I've had a couple of people mention to me that they've made metal Wolverine claws out of bobby pins. I tried cutting my bobby pins myself, but it didn't go so well. I either need stronger hands or better tools, but you'd probably have better luck!

[@batshad0982]

Can you mold a marvel legends head

[@alienintoxication09]

How strong does the clay dry ,,,like resin? Or Does it break easy??

[@Zubbie]

The Apoxie Sculpt I used in this video is stronger than a lot of types of clay, but it can still be carved easily. However, I don't think it is as strong as resin.

[@bleedingflesh224]

Thermal beads should work

[@TheInfinityLion]

Do you still make videos?

[@alvischan5379]

My experience is much more worse, there is a cheaper version of “blue stuff” here in China, it’s shape like rice, after I heat that things up, it become much more sticky and after it cool down it just hard to bend like the video does, so hard that I just use it as strong material to fix my broken headphone, and the AB putty I also chose the cheapest one, because at that time I thought tamiya putty is way too expensive, I want to mold 72 scales model parts, but you know the scale is so small and full of detail, and I tried like more than ten times, it all failed at last, I followed the instructions and plus I wait 12 hours for the putty gets hard, but the putty is getting tearing apart inside the mold, and i can’t even take it out, just all messed up, after that I tried to use Vaseline on the surface so that it could easier to take out, but it still so broken, I think maybe the putty is so cheap and trash and maybe the “blue stuff” i bought is cheap and trash too, btw u r right, small scale is really hard to duplicate, I will try different putty, if I failed again with the expensive one, I would be so sad for spend so much time and money for nothing

[@jasemcmicky]

it is a trigger guard just for future reference.

[@Zubbie]

Thanks for letting me know. 🙂 I'll try to remember that for next time.

[@jasemcmicky]

Zubbie no problem, thanks for letting me know about this cool product!

[@WysteriaGuitar]

One more question, can you use polymer clay to fill the mold?

[@Zubbie]

Sure! The molds have some flexibility to them, but I would still use some kind of mold release to help get the polymer clay back out of the molds without distorting your clay. You can't bake while the clay is still in the molds, but that's the only drawback I can think of.

[@MalakaiSchuhart]

where did you get the guns

[@Zubbie]

I can't remember for sure, but I think the guns are from the Marvel Legends Deadpool figure from the Juggernaut Build-A-Figure wave.

[@MalakaiSchuhart]

thanks:)

[@BretPangilinan28]

Can I use resin (EasyCast or FastCast) instead of the epoxy clay? I cant find any info about that. Thanks!

[@alyssakelley4995]

Yes you can. I use this stuff with UV resin because composimold and remelt (2 reusable mold makers for resin) kept melting under the UV light.

[@johns3153]

I wish I could make the guns I've tryed but keep messing up they don't turn out as good as yours​

[@Zubbie]

You gotta just keep trying! My first attempts didn't turn out as well as I wanted either.
