I recently bought an old Delta drill press( circa 1940) and the main shaft and other parts have surface rust. Does anyone know of any tecniques to get the metal to look new using chemical means? I was thinking of naval jelly or something. It just seems that when you use scotch brite and some wd 40 it never gets that nice shiny look.

I've used naval jelly on antique tools once and it turned the metal dull. Definitely won't work if you're going after the shiny look. Spraying the metal with wd-40 and sanding with 220 grit sandpaper works for me when I clean up old planes. I've used aluminum wheel polisher sold in auto supply stores to give the metal a good sheen. Worked well.

Getting the metal shiny is simply a matter of polishing the surface. From a functional standpoint, it's unnecessary, but I too prefer to have my tools looking good. You can accomplish this simply by buffing the metal surface from low grit to higher grit until you achieve the level of shiny that you wish for. Get ready for some serious elbow grease, or use a buffing compound with an electric buffer. I've got one for buffing out cars, and I was able to achieve a mirror finish on my cast iron surfaces with some compound.

Believe it or not, you can do pretty well using a sander with a Scotch Brite pad (instead of sandpaper), with something like WD-40, Boeshield, or even paint thinner as a lubricant.

I wouldn't try to make it look new, just clean and functional. Check out the FAQ at owwm.org for more on cleaning. If you really want everything "like new", google for imformation on removing rust by electrolysis.
