i have a 12" sanding disc that i can fit in my lathe cuck now all i need to do is make a stand to fit my tool post to hold the rocker. i searched my steel supply last night but couldn't find anything the right size to fit the rocker arm, i'll have to machine a piece of round stock. just by eyeballing it, i don't think you can get a full arc on the rocker tip from a stationary mount to a flat grinding or sanding disc it just doesn't fit one would have to use the edge of the disc, i could be wrong, it just looks like the rocker holder its self is going to need to pivot. i would like to lock the tool post then surface the rocker tip, more engineering today.
