/diy/ - Do It Yourself

Thanks; Yep, it was my second batch of silicone (first went towards larger, 3D printed parts) and first time painting a figure of that size so it's a lot grainier than what I can paint now.

I wouldn't really recommend recasting specifically Mechanicus due to all the fiddly bits - I had a hell of a time smoothing both halves of the mold out as well as figuring out where the mold line should be, whole process took me a couple of months for a Start Collecting box. I don't think it'd take more than a week for a figure or five, though.

Pic related is probably a terrible idea, but I made a tiny pressure pot out of a mason jar (the lid HAS to be of this type or it won't hold pressure), some valve, silicone caulk, and a bike pump. Works well enough when pouring resin to get almost-clear results. Obligatory disclaimer: don't use over 10PSI, I'm not responsible for your injuries, etc. etc.

Honestly when I made pic related I was a poor college student. It's a pressure chamber, not a vacuum chamber, but it worked well enough for the cast you see.

This is the new, sort of working jar. It can take a pressure up to about 10psi - I don't know exactly how much, because the pressure is lower than what registers on the pump gauge. It doesn't go any higher than ~10psi without leaking - I think this is because the dents on the lid pry up the edges of the lid and break the seal. The brass fitting is just a ball valve so I can disconnect the pump and have the jar by itself.

Into the top, I "glued" what I think is a Schrader adapter which came with the pump - it doesn't really matter what it is, it just needs to provide a seal to the pump. You could feasibly use a regular bike tire nipple, I think, but this is what I had on hand. It's secured in place with the mixture mentioned above - Silicone I, food coloring, and cornstarch.

Note that the lid is a different design; it's kind of hard to see here, but the lid actually has threads and screws onto the jar instead of just holding there. I think this is what makes a huge difference.
