Why 1″? Is that the size of the lapping films?
Yup same here, I use 3/4″ cause my paddles are 20.1mm. 3/4″(19mm) is much closer to 20mm than 1″ is.
I use the Scotch double sided tape also but I use the permanent cause I had a roll laying around. You don’t really need the removable stuff, the permament & removable types are for use with paper. I use the permanent on aluminum paddles, it comes off no problem & stays on the sandpaper. I don’t care about removal of the tape from the sandpaper cause it gets thrown away anyway. When I run out I will buy the permament type again.
