I haven't made one yet. It's on my to do list. I hope to have made some progress by the end of the year

It's funny though: beltgrinders like the bader and the kmg are sold without problems in lawsuit happy USA, but in europe you can't find them because there are strict regulations regarding power tools, and noone can sell grinders like that with accessible free rolling belts that can grab and crush fingers.

Anyway that is why Europeans are force to build their own, or pay someone to build one.
