I did some more sanding today. I used my electric DeWalt DA sander with 320 grit paper. And it was doing exactly what I was wanting it to do. Basically knocking down the primer to a very smooth finish and then I could do some touch up with hand sanding and spot filling. However, after sanding for an hour or two, my sander was making some funny sounds. I kept sanding and then decided to stop and see what was going on inside the sander. Glad I did. The random orbit section has a ball bearing in it. And it was almost seized up. Very rough and hard to turn. So I disassembled the entire sander and clean everything. The armature was in perfect condition as were the brushes and support ball bearings. I did polish up the armature to bright copper and luckily I had a few replacement bearings in my bearing drawer and after reassembling everything, it is back to working like new again. But I didn't go back to sanding anymore because it was getting late in the day. I did get about two thirds of the hull sanded though. :eyebrows:
