Re: Disc trimer /cutter
Unless you have many to do, I use an old pair (Chinese made) of aviation snips and do it by eye. The uneven edge actually helps for some reason.

As stated aviation snips work well considering the $200+ price tag. https://www.morganmfg.com/ab_cat05.htm

Re: Disc trimer /cutter
Somewhere awhile back I saw a tip in a magazine that said to cut "V" notches in the edge of the disk. Similar to your method.

Re: Disc trimer /cutter
Cutting "V" notches or cutting the disc in the shape of a triangle or square was not meant to provide a 'fresh' area of grinding material but gave flexibility to the disc that allowed it to conform to curved or convex surfaces. (did that back in the 50's)

Re: Disc trimer /cutter
Don't know what kind of discs you are talking about but the autobody surfacing discs that are being talked about generally have to have about a half inch or more removed to get to fresh material.

Roger on that. It takes a bit of practice to see what angle to hold the grinder but it works slick.

Re: Disc trimer /cutter
2x on the bench grinder if it is a hard disc. The more flexible ones will need trimming.
