Man, my fingers are sore. I have been hand sanding a pair of scales for about 12 hours total over the past 2 days and my fingers are sore from holding the sandpaper! I just now got to 400 grit right before I quit for the night tonight. What sucks is after all that effort the fit still sucks, have gaps. But hey, at least I am getting in the shoulder workout from "seesawing" (guess thats the best way to describe it). One thing I noticed if you split up a old 120 belt it works pretty good for material removal for the most part in the beginning. I used too much thread locker on the corbys so now I have blue coming out of the pores around the rivet. Then I ask myself why am I sanding so much on a beater knife? Ugh.:grumpy:
