Got around to shaving down my forks yesterday. Thanks to previous posts on the topic gave me the assurance I could do it without a lathe. I used a 4" cut off disk, grind wheel (carefully), electric sander with 120, 220, 400, 600 grit dry, then polished with wheel. couple of small waves, but hey, it was my first time and I am really satisfied with the result. Sorry for gigantic pics.
I've done many a set myself. Just like alot of things, it's amazing how critical you are about your work because of the way it looks on the bench, or when it's right in your face, but just think about when the part is actually bolted on the bike and it's inches from the ground and several feet from your (and everyones) eyes. Minor imperfections aren't even noticed.
