Ok as promised here are some pictures. I tried the 220 grit first and it was very very slow but would be a nice finish. Then I bought these 120 grit (5/8) which when used with transmission fluid did a nice job. But it could still go quicker so when I looked this up for you I put a 80 grit in my cart. Here’s some pin gauges that you can buy separately to quickly check guide clearance and some clean up buffers.
