I recently cleaned up a two-man crosscut saw a friend gave me – i.e., made new handles, sanded off the rust and sprayed on some Polyurethane to prevent future rusting. I will hang it in my shop for display and conversation. The poly finish came out really nice and got me wondering if the same treatment can be used on my table saw and other cast iron tops to prevent rust? Anyone ever done that? Any reason not to? I currently apply wax after cleaning up my cast iron tops, but that requires occasional maintenance and re-application.

I would think Polyurethane would wear and “crack” with saw usage. Then you would have the added problem of cleaning up the damage.

NOOOOOOOOOOOOO!
I don’t use poly on anything, much less on my tools.

I noticed this on Matthias Wandel's site. Seems like it is worth a try. -Jack

some people put clear shellac spray on planes to prevent rust. I wouldn’t put it on a table saw, but that might be a better preservative for your saw than poly.

Have your say...
