Rust

[frontier52]

Good afternoon everyone... new to the forum and the information I have found has been very helpful ( thanks to everyone for sharing ) I've been working on a craftsman saw but the top was rusted pretty bad. After cleaning, grinding and sand blasting their are some serious pits on the top. Does anyone have any good solutions for a repair?

You can use JB Weld to fill in or take the table to a machine shop and have it Blanchard ground.

Welcome to the GJ. Why not go to "Introduce Yourself" and fill in some info?

52: there are a few ways i know of to fix those pits. JB weld is one like Zeke mentioned and i hear Devcon works a little better and is spendier. another way is to weld the pits and grind them smooth or if you have the means to do the method of cutting a new top like Zeke mentioned that sounds like the best fix.

I like both of your ideas, but the welding one appears to be the most economical. Stick weld, wire weld which would be best?

The top is usually cast iron with aluminum extensions. How big are these pits? If they're not to big just leave them alone. They shouldn't have any effect on the way the saw works, as long as they're not to big ... 1/8" in diameter or smaller. Take a flat file an make sure there are no high spots on the edges.

Depending on if you are fixing to sell it or use it.

If using:
The top should be flat, not pretty. If grinding and blasting has warped it,
have it ground or planed.

If selling, then pretty is all that matters I guess.

Why not find a cheap one with a good top to replace yours?

JB Weld is an epoxy with metal mixed in. It has nothing to do with welding.

I'm not familiar with JB Weld. Help me out there?

Not to be the bad boy but in a vintage tool section are we to understand the rust is vintage in some way?

I am hoping the op is going to show a picture of a pre 1965 saw...

It's a two part epoxy: http://www.jbweld.com/ Most any hardware store should have it.
