Hi Guys. I just bought some old woodworking machines at an auction. The work tops of the circular saw and the planer is all rusted and gritty. How do I get the surface back to its original(or almost) state?

I have had success with a scotch brite pad, elbow grease, and penetrating oil

Joop try using a finish sander with 220 then 280 and then 300 grid paper. During the last pass with the 300 grid use a circular motion over the whole surface. did you get my e-mail?

I always soak the tool with wd40 and then wet sand (by hand) with 400 if it is just rust, but 150 if it is scaled.
Definitely follow up with paste wax of some kind. I use turtle wax, but johnson is good too.

All of the above will work well but be careful. Sanders or power grinders can quickly create "groves, swirls, and scratch marks" that can be very hard to correct. Paper coarser than 400 grit can do fast damage. Just be gentle.
If a table has serious scale or rust flowers borrow a "scraper" from the machine shop. These heavy handled tools have stiff 2" - 6" blades. These are not putty knives - but look a lot like them. Have the machine shop guy show you how to use them - there is a bit of learning curve. They take elbow grease but will do a very good job. Then follow up with wet/dry paper,, polishing pads and wax.
This is a real "old timer". I was taught to "flatten" the shop sharpening stone by polishing the machine tables with it. Could this be "three birds with one stone? Flatten a stone, polish a table and keep the ADD kid busy.

Mike,now thats a good idea. The finer stone method makes a lot of sense. I've started of with very fine steelfleece (000) and elbow grease. A bit tentative on the courser stuff.. but thanx for the advice. I'l be careful.
