Roto Caster

Attempting to cast thin walls for my bug below, and failing, I realised how tired I was of 'rolling' the mold around with my hands until the resin set... as with other projects. So I decided to make something that would do it for me.
I got the gears and chains for free from charitable cyclist store, the wood, metal rods and other bits cost about $70-$80 I guess, so, In total, its far cheaper than the ones you buy for a 0 or 2 more.
It still needs a little tweaking but so far so good. Ill test it out this weekend when my long suffering girlfriend is at work and wont have listen to the drill that powers it go on for an hour or so while she tries to study...



 
The idea is that you place your mold, with the liquid material inside, in the middle of the machine and it will slowly slosh the material around, evenly on all the walls, it isnt designed to be centrifugal. 
The irregular speed in the video is purely due to my poor drill trigger squeezing skills:)
