I searched but came up empty. Might be because I'm not sure what keywords to use. I'm restoring a couple of '60s Ludwig 3 play shells and I've done this before without any mechanical aid. But this time I'd love to be able to have the shells on some kind of device that allows me to rotate them with ease. I'm comfortable building it myself and I could probably figure it out McGyver style but thought I'd ask here in case someone has advice and more importantly photos of their setup.
