A while back I showed this old vise I picked up last year:
After a few applications of penetrating oil, I finally managed to get it all apart, and spent a couple hours on it with various wire wheels today. I managed to get it pretty clean; not as good as with a blaster, but plenty good enough for repainting.
Not much of what remains on the metal is rust - it had a red undercoating beneath the gray paint, and the wire wheels just can't get it out of every little pore in the cast metal. The primer covered it all just fine anyway:
Looking a lot better already! Now to look for a really good, durable paint for it. Not sure what color yet. I'll mask all the parts I don't want painted for the final coat, but I didn't bother for the primer.
I saved these homebrew dust-collector parts from the scrap last year. I spent a couple hours on Thursday cleaning up a few of the welds around the seams and tried out my el-cheapo gravity feed paint gun with some black semigloss enamel paint I've been meaning to try. I've never really painted before and know nothing about mixing, but I think I could've gone thinner still. The paint said to use naphtha to thin for spraying, but I didn't have any so I just used lacquer thinner. It seemed to thin the paint just fine, but it took forever to dry. It's super hard now though. I have a 1-1/2 HP C-face motor from a blown jet pump that I'm going to put on it. That should be plenty of power for it - it's not a terribly large blower and it's only running 4" pipe. I won't be able to build much of a system around this unit, maybe two tools at once, so I'll have to build it on a cart for now. Better than what I have right now though (16 Gal. shop vac)! So far the only money I'll have into it is for a small pulley for the motor, since I don't have one on hand for a 3/4" shaft. I may get new bags later on - there was a set with it, but I had to stitch up a couple small tears, and some better bags would help with performance anyway.
I picked up this old diamond Eze-Lap sharpener yesterday for $3:
Nice heavy brass. I love it. I hate the modern trend of making everything smaller and lighter. It's good for some things, but not hand tools really.
