Subject: [Puptcrit] TECH: Theory: rotomolding box

I've just had a flash for a possible low-tech solutin to a semi-high-tech need.

When casting latex in plaster molds (slip casting), I usually have puddles of latex accumulating in places I'd rather not have them.
It's hard to prevent it, I'd have to be there next to the mold and turn it every 3 minutes.

Some shops use a system that turns their mold constantly at slow speed.
I've no idea how their machines work, I doT, know where to look for answers.

Unable to figure it out with the limited tools I have, I switched the problem around. I first wanted to find a way for a strong enough shaft to fit into each mold or grab them somehow with a claw-like attachement. Not easy to make it universal enough...

So then I had a flash about a box. If I made a strong wooden box, and fitted the bottom with the same fittings as the ones on grinding wheels for my bench grinder, I could perhaps attach the box steadily to the grinder. The mold would fit tightly in the box with polyfoam stuck between them. As for speed, I have a pedal I could use as a dimmer, and keep it at the desired speed with an elastic band.

What do you think?
