Making Your Own Toy

[franz bolo]

So the sculpt was done, now comes the mold making. Here are some progress pics.

I will end up doing them solid resin but my friend has a rotocast machine and I want to try it out.

what kind of silicone are you using there?

 

[franz bolo]

I believe it was Walco GP25.

Got the second side done! It de-molded fine with no damage to the sculpt.
You notice the other half is blue. We used a quick cure catalyst so I could try to prep for casting later today.

I take it this is part of your avatar?

Oooo! DIY vinyls.

Now you have to do them in three hundred different colors, each with a fat cigarette hanging out of its mouth, and a price tag of $60 each. :lol

Then I'd have to change my name to Frank Kozik!! :lol

BTW, here is the first rotocast. The original sculpt is on the left.

Yes, that's my avatar. Here are the initial drawings I made.

so where is the pour spot

so where is the pour spot

Here is the pour spout. I cut it after the mold was cured. That way you get a super tight fit. When it was rotocast, I put the plug in. There is a small hole drilled in the plug so that some of the heat can vent.

Apparently the resin gets hot and expands. The hot air would bulge the mold if it couldn't escape. The heat and a little resin goes out the hole.

You have to put a little zip lock bag around the plug when you rotocast it so it will catch the resin. If not, the resin will fly around the room.

Awesome! Can't wait to see your paint-ups! The rotocast turned out great... :thumbsup

The problem with the rotocast one is that the resin must have kicked while it was near the front because the toy won't stand up!

Here are the 2 colored ones using the tinted amber resin (smooth-cast 325). The second pic is back lit from outside and really shows the color off. These have not been cleaned up yet. There's a small line where the molds comes together but it can be sanded off pretty easy.

Thanks, that's the size.

Here's a few more pics. The gray one hasn't been cleaned up yet. I wet sanded the green one a little. There was a lot of small air bubbles in the green one for some reason.

BEAUTIFUL JOB! I can't wait to see it with the eyes!

 

[franz bolo]

Thanks.

Here's a small update. I got a gallon of resin in and started to cast these today.

I ran into some problems with air bubbles. I had the same problem on the colored ones. I had to sand and fill parts of them. Once there painted, you won't be able to see it but the clean-up was pretty time intensive.

Oh those are so cool!
Where can I buy one? :love

Oh, when you said 'make your own toy'.........and I saw that thing......well......I was thinking something totally different.

Yeah, that's prety cool.

All those protrusions ad indentations just to make sure the 2 halfs line up right? I usually only see 4 to 8 on any mold... :confused

Yes, you can make however many you want I guess. Once the halves are together, it doesn't budge!!

The series of tiny ones close the edges of the item being cast are very smart as that's where you're likely to get mismatching seams.

Great looking castings even with the bubbles, do you have any finished yet?
