I've been purchasing an assortment box (80, 100, 120, 150, 180, 220, 320, 400, 600) of Abranet strips from Amazon and cutting them into 2" discs. I get about 4 discs from each strip, so I get 4 2" discs in each grit for about $20 total.
I'm wondering if I can't do better, though. I like the way abranet cuts, but I'm not stuck on it either. Looking at Vince's store, I see I can get some of the grits (80, 120, 180, 240, 320, 400) in 2 3/8" disc 15 packs. So... two questions:
First, do I really need the intermediate grits I've been using (100 and 150, mainly)?
Second, are there are more economical alternatives (with Vince or elsewhere) than the Abranet which work as well? (For background, I'm powersanding and I have a bad tendency of going a little too fast, especially with the 80 grit). This is primarily for bowls. I use some bulk sandpaper rolls for spindlework (mostly pens).
