It looks pretty good. I will make foam latex puppet with silicone hands.
I used to have some thought to make my own, but after reading the machinery guide in the forum and measuring my basement, I think it is better to buy some armatures:)
I saw one of these a few months ago. They are certainly very good value.
The joints felt a bit rough and would need some serious attention to get them working smoothly. The plates are made from mild steel. Having said that, the puppets made on the website look very good, and there seem to be some satisfied purchasers.
I am a fan of Animation Toolkit's joints, which are cast stainless steel, take lots of tension without bending, and come with part-drilled stainless balls. But their kits are more than double the price.
