I have been hankering for a 20” disc sander to flatten big segmented bowl rings for glue up. A long continous streak of not winning the lottery (maybe I should buy a ticket) had reduced my options to the home grown version.
Some leftover MDF, a hunk of rock maple, tap the maple and add a 20” sanding disc ($14 on Amazon)
Problem #1: I need to either raise the lathe or make the maple longer to exted over the edge of the table without sliding the lathe all the way to the edge.
Problem #2: I need to make the face of the maple block more carefully, or use something other than MDF, not sure which but it has the slightest wobble.
Wiley Coyote moment: Disc is so big that in order to get the tool rest against the edge to finish the edge of the disc I had to reverse the lathe. Turned the lathe on, it flashed it’s warning and instead of turning the disc it simply unscrewed the tapped maple. In what appeared to be slow motion the disc bounced once and karate chopped my shin. No permanent harm to disc or shin.
