6" sanding disk

6" diameter flat sanding disk/lap with 1"-14 threads (might need a tap or thread chaser to clean up the threads depending on how your slicer deals with the geometry, but its almost good enough as is)

I'm using [harbor freight spray PSA glue](https://www.harborfreight.com/24-oz-industrial-adhesive-spray-93792.html) and wet/dry sandpaper on my cabochon machine.

It needs some work as the edge of the plate got the shakes pretty quickly so a revision is coming up.
