I just wanted to report on my progress with the Prentiss vise I picked up a few weeks ago. After disassembly, I had to come up with a solution for the missing crown nut which goes on the handle end of the screw. A set-screw collar looks like it will do the trick. I just have to drill a small hole in the screw for the set-screw.
I used some Jasco paint stripper to remove the old paint. It bubbled up in just a few minutes, and it only took me an hour to get it all scraped off and clean.
I have now started on my home-made electrolysis tank to remove the rust. The base is bubbling away in the tank (thank heavens for HD buckets!:thumbs

), and it looks like 1-2 hours should get it clean.
I'm still kicking around ideas for paint color. After I stripped off the greenish-gray coat, I found a few traces of red in the logo---not the letters, but the underlaying portion. I'd like to find out what the original color scheme was. I've searched on GJ and Google, but there don't seem to be many Prentiss vises of this vintage. The branding shows "Bristol CT" as the place of manufacture, which seems to indicate that it was produced after Prentiss was taken over by Chas. Parker. I may end up going wild on the color (yellow, to match my car???), but I'm leaning toward keeping it more original.
One more question--I'd like to keep the slide fairly shiny, but still looking like "natural" bare metal. Would boiled linseed oil give that appearance? Or should I just use a paste wax or sealant?
