5.5 Resurrection. Treegarr, Wo-man, and Remco-style rubber guys. Keepin the fire alive.

 As I've got a lot more time to spend in the resin room, I'm really churning out stuff and trying to keep the shop full, keep coming up with new figures, and continuing on my current lines.

Treegarr is too much fun to play with so I'm releasing 4 new colorways; Emerald Ending, Radtacular Blood-sucker, Blazing Cold, and Maxx'd-Out. 



 

I'm planning on making them ltd.to 3 of each, maybe even 2 if the molds don't hold up too well.
 I've fixed Wo-man's molds so I can at least finish the quota of 20 original colorway, and 10 Faker. I think it got to 7 original and 3 faker left (I'll have to check) so I'm introducing Slime-pit Wo-man (clear green) to give people more choice, and something for people with a complete Wo-man collection so far.



I also have quite a few flawed rubber bodies from my Remco-style buck (the static 5.5" body I've used for all my MOTU-style releases the past year or two). I'm going to stick random parts on them and put them in store as bootleg-style toys for super-cheap. I just need to clear out and I'm sure people will enjoy having a 5.5 you can throw down the stairs and never break.

On a day-to-day, BMT is growing for the first time in a long time. Having more time to give to it, I've been able to work on new ideas in the background and keep producing,and keeping the store interesting.

Inspiration is always there. Just cruising the right topics on Youtube or reading interviews with sculptors, and toymakers usually gets the juices flowing. New techniques in Z-brush, stuff people have made on Thingiverse, etc. usually stop me from picking up a joypad and procrastinating.
Before I'd ever made a single thing, San Francisco Toymakers (who made WCW and ECW figures at one poing) used to have a feature on their site in the early 2000s on how they sculpt, and tool their figures. That whole thing really excited me and I didn't forget about it until I was ready to start doing it myself.

Right, back to it. Cheers! :)

My top tips for casting toys and figures in resin and rubber. Saving on materials, preventing bubbles.

After 4 - 5 years of making primarily hand cast toys, I'm finally collaborating with the man who taught me how to pressure cast, Austin aka Gold Dober. I'm very honoured and personally very happy about it.
I've collaborate now with everyone (except for COTU world) who I looked at in the beginning and wanted to have a go at resin production myself. I'll update with details when I have them.

This isn't going to be a guide on how to cast for complete beginners, more a few things I've come up with along the way to help me with troublesome molds, and to save materials.

 SILICONE STICKS TO SILICONE. MAKE THE MOST OF IT!


You probably know what a waste mold is - it's where you make a mold using waste silicone. Any silicone that isn't covered in mold release will bond with whatever curing silicone is next to it. Think of it like hardcore and concrete. Hardcore is cut up pieces of old mold, concrete is the new stuff which bonds it all together. You will need a pressure pot for this to work though.

RECYLCLE

All of my large molds are made with a lot of waste silicone.
Here you can see the blue chunks that were used from previous molds and the pink from new silicone. They are different shores, brands, etc, but it all sticks.

SPOT FIXING

I did a quick vid on instagram how to replace part of a mold that is mostly fine: https://www.instagram.com/p/BKbE1pagMXK/?taken-by=bigmantoys

As long as the original model is strapped in tight, the mold should be perfect. The rest of the mold will still give way eventually but these weak spots can be fixed several times. Here are the results of the above video, you can see the shapes that will make the negative shoulder articulation- ive already had perfect pulls from it:

RESIN - IT'S BETTER TO WASTE A LITTLE THAN WASTE THE LOT.

By that I mean, "topping up" molds where you haven't poured enough, or having bubbles because you didn't cut fat enough ducts make the sacrifice of a bit too much resin worth it.

With really bad undercuts, like the back of Blade's hat, I use a method of letting it leak. You can see that I've sculpted him so everything except the hook (which can be vented easily as it's near the feet) is facing upwards, meaning I could in theory have just one vent from the hook to the leg, and one from the feet to the bottom and I'd be fine.
But the back of the hat is facing the opposite direction. Casting in rubber, I wouldn't havea  hope of that being bubble free...

So I drill a hole from the outside to the back of the hat's peak. The material leaks a tiny bit, but also takes all the bubbles with it. 

 Here's something you can do with fast curing stuff - stick a toothpick or stick all the way through...
 Leave it in and pour the material (resin or whatevs) at the top.

Pull out the stick - it creates a vacuum, rushing material to the hole on the side.



OTHER GUERILLA METHODS

I learned with plaster before I used resin or silicone, and then i tried casting without a pressure pot or vacuum. I learned some stuff that still comes in handy.

1: Air can't go where something solid is.

I sculpted this giraffe head (Im putting this custom in store BTW) with horns at the top, they are narrow with bulbous tips, meaning theres an area that needs resin with a small amount of space for the resin to get though. Also, down  at the bottom of the mold, air will get trapped there first. 

 So again, I put a stick there. It holds that narrow part open and also blocks anything (air or resin) from getting there.
Pour in the resin with the stick still in the mold.
Pull it out and dispose, as there is no air there to go to that part, all that can get in is resin. Obv works better with a pressure pot but helps still if you're not).

2: Poke, bang, and rock.

If you're casting something really thick, or are casting without a pressure pot, you can minimse bubbles in a few ways. You can poke the areas where bubbles happen before the resin cures, with a stick, you can bang the mold from several angles to try and smack out the bubbles, and you can pour a little resin in, and rock the mold. With only a little resin, rocking should make a shell inside the mold wihtout enough liquid to trap air (bubbles). Once that's at least half-cured, you can pour in the rest. Any bubbles will be internal, where you can't see em!


WHATS LEFT IN THE CUP

I try to always have a mold at hand with a wide opening that I can pour into quickly. All my leftover resin after a pour goes in these, and after a few pours, I end up with some bonus casts.





Also, I've recently expanded my Bigcartel store (upgraded account) and am putting in EVERYTHING I have in the studio. I'm really low on space so it's all priced to fly.  http://bigmantoys.bigcartel.com/
