Re: 55 Wagon Progress
I was using 80 grit there. I've tried 60 and 120...... 60 seems to leave too deep of scratches, 120 seems too fine/slow at acting. 80 is a happy medium. I don't change arbors, but my 3" arbor is actually about 1/4" shy, so when the outer edge loses its bite I will cut around the perimeter up to the backing using a pair of tin snips to get a bit more life out of them.
