That makes sense
He's going to add gears so that the two rotating rings are linked & he's going to do it so that they don't realign flat again for a number of rotations, I think he said something like 15 turns. So it wont be geared at exactly 2:1. I get a little confused when it comes to gearing so I may be getting these numbers a bit wrong :$
First off it'll be hand cranked, the crank will be removable on a key so at a later date I can motorize it. I do have a 1/2 hp motor I could connect upto it but I'm thinking that maybe a wiper motor would do the job, wiper motors can produce quite a bit of torque.
He's also made it so that the feet swivel & it can be stored flat against a wall. Its big as well, the inside rotating ring is one meter square inside. He's also going to drill holes in the inner ring so that moulds can be mounted in various positions & it'll have a removable mesh to mount smaller moulds to it.
I'm looking forward to using it
