check out a product called micro mesh. its an abrasive on a pad ,a pop sickle stick, paper. comes in sets from about 400 to 12000 grit in a set. i have found looking at other crafts and hobbys there are a lot of things that can be reporposed between them. leather stamps that are inked, rubber stamps, lapidary disks. i got one of the $12.00 hand held vises that had a bunch of 1/8" holes used split pins and small cap screws to hold work. i removed the handle and cut a chunk of wood and drilled a hole were the base of the vise where the handle went in would fit. i had a cheap small light weight carry around vise for hand push engraveing.
