Too much rust on this Delta Contractor saw?

I'm looking at a Delta Contractor saw tomorrow.

The seller wants $200.

He says its hardly used and there is "surface rust that will easily scratch off".

Based on the pictures, do you think the rust will be insignificant or will it leave deep pits?

Is $200 a good deal? This is my first saw and I plan to build some cabinets, etc.

What Rust?

You would have to leave the machine out in the elements for years to get any kind of significant pitting that would effect operation. Added bonus - that machine has one of those magical motors that are 1.5hp @120vac, but bump up to 2hp @240vac :) $200 is a very fair price for that machine - the Unifence is basically worth the asking price alone.

Cheers,

Thank you for your comments. I was debating between this Delta ($200) and a Grizzly 444z ($400). I don't have 220V at home, so in the end it was a pretty easy decision for me!

Well, I was also looking at a 1940s Delta for $100 but it appeared to have no extension wings.

I plan to pick it up tomorrow - I have a Honda Pilot with about 5 ft of depth in the trunk.

If necessary, is it relatively straightforward to remove the Unifence rails?

I can also rent a 5×8 trailer for $30. Would you recommend the trailer or disassemble?

I bought one of the older Ohio Forge saws in worse condition than that for $200.
I estimate it weighed over 300 pounds. we spent a good amount of time taking
it apart to fit in the back of my Dodge Durango. getting it out was a chore, but done.
hope you can snag it !!!! (take your metric wrench and socket sets with you as well as SAE).
a quick run-over with the R/O sander will polish that bad boy right on up !!

I partially sanded the rust spot, but the rust spot keeps forming. Am I not sanding deep enough?

Flash rust can form almost instantly on unprotected cast iron. Scrape off the worst of the rust, then apply some sort of rust preventer with fine steel wool. That will take the flash rust back of while adding a layer to prevent more from forming. I just use Johnson's paste wax on my tools. Others like T-9 or similar.

Pick up some Loctite brand extend clear from local auto parts store, Lowe's, or some Walmart's. You will not find it listed on the web sites, but most my local Autozone carry it. Loctite sells a version in bottle for brush work, but spray version is much easier. Extend will change the red iron oxide into stable black version of iron oxide, which will not grow or consume any more metal.

Extend spray works great for preventing rust on cast iron. I use it every 1-3 years on my cast iron tables. After removing as much rust as possible, flush & scrub top with solvent to remove wax and dirt. Spray a light coating of Extend on entire top. Once dry buff with white nylon sanding pad (or 600-1000 grit paper, or brown paper bag). Then apply wax with another white nylon buffing pad for normal rust protection. This treatment seals the pores in cast iron, and blocks the starting point for most rust with acrylic polymer that does not transfer to wood.

Some folks recommend wiping on a water based polyurethane as an alternative cast iron grain filler. Have no idea if it is better or worse than Extend coating. Have used extend since 90's and it works like magic to stop rust.

PS - Permatex is consumer brand owned by Loctite to sell into certain market segments. If you find Permatex Rust Treatment spray, it is same chemistry with different label. :)

Best Luck.
