I'm not sure if this goes here, but there isn't a tools forum...
I am collecting parts for a thickness sander. The only thing that isn't an easy off the shelf part is the drum itself. I could make one on my wood lathe by stacking MDF discs but that will not be perfectly square and I would like to get as close as possible with it. What have other members done for a drum? This is for sandpaper in strips, not the sanding sleeves.
Thanks,
Mark
