My Dad and Grandad had this brace before me. I'm trying to get it all cleaned up and back in working order. I got the rest of it taken apart and will get that cleaned up. However I've taken the screws out of the knob and can't seem to get the wood part off. It spins decent when vertical but there seems to be a catch in it when spinning while horizontal. I was hoping to get it apart and get all that cleaned out too. Any idea how it was attached in the first place? I don't want to give it kinetic encouragement without first knowing if it is stuck or not. Any help would be great! Thanks!
