How do you remove rust...

from the top of a table saw.

I have had for years and old industrial table saw. Cover it every winter and then clean it up come summer for the few times I use it.

Uncovered it today and the plastic tarp I had over it leaked.


May not look that bad, but the left side is really rough with rust. Tried steel wool by hand and got the easy stuff off. Sprayed it with WD40 and Liquid Wrench. Got more of it off, but the worst of it is still on. Every used my Mikita electric hand sander with steel wool underneath it as opposed to regular sand paper. Still can’t get it off. Do they make sand paper that is for metal?

Other ideas?

Yes Daddog, use emery paper, that is for metal, it has a cloth backing and is often black. Or wet or dry paper, that will work also.

Off to the local hardware store.

Did you have any success Daddog?

[daddog]

Hardware store was closed. They roll up the sidewalks early here in this small mountain town. After that Gloria was working the next day and I had to take the little one to swimming lessons. Then we packed in the afternoon and headed out of town the next day.

Back now. Should have time to try it today or tomorrow.

 You can also use a wire wheel or wire cup brush(medium)and a drill.
 To keep it from rusting,buy a block of parafin wax.Cover as much of the surface as you can,then rub it with
a cloth(a rag from a sheet is best)to cover as evenly as possible.Wax has two benefits,it helps to water proof
the metal,and provides lubrication between the surface of the saw and the wood you're cutting.
 I've been a woodworker for 12 years.I'm classified as a Primary Wood Machinist.

ps.don't tell Malap

That is what I did today. Bought a brush of sorts that is designed to take off rust. I put it on my drill and away we went. Raised quite a cloud of the red stuff, but it worked great. 
Took me about 30 minutes and got about 90% of it off. Will finish the removal process tomorrow.

I will try that this winter mook. Thanks!

 Well Mal,most Metal Machinists I know,poo poo the title Wood Machinist.
 daddog,we used to wax every,wood-metal contact surface before every use.I mean like,saw shoes,hand plane
shoes,table saw tops,jointer tables,router base plates and even the sides of saw blades.It's really a difference in ease,and the less force you use,the less chance to bind in the cut.I hope I don't sound like a know-it-all,but wood working is my GIG.Just ask me,I'll tell ya.

Mook is right.  I have built furniture for years as a hobby.  I would caution against wax with silicone, it can cause problems while finishing your projects.  I use the Boeshield products and have been happy with the results.
