    Casting Iron Table Saw Rusting

    Anyone else own a cast iron table saw? I have a Ridgid table saw that has developed some areas of rust. Nothing deep yet. I have cleaned the surface with scotchbrite pads and WD-40 (something suggested by a forum I visited) and then applied Johnson's paste wax to the surface. But it still appears to be getting the rust stains in the same place as before. I can't seem to prevent the rusting.

    I had the saw for 4 years in CO without any rust but the air is much much drier there.

    Anyone have a suggestion?

    I would suggest buffing it down with a course brush to get the rust out. Then try a wax to help seal it.

    Re: Casting Iron Table Saw Rusting

    I have Delta Unisaw and I use Top Saver that I bought at Rockler. It seals and lubricates.

    On my jointer I've used paste wax since new and never had an issue with that either.

    I also keep my cabinet saw under a cloth cover when not being used. It keeps the saw clean and allows moisture to wick away and not be trapped.

    Good luck, I HATE rust when it come to my tools.

    The place I'm having a bear of time with is the miter groove built into the surface. I can get the rust completely gone (at least to the naked eye) and polished and then waxed but it seems to be back after a week or so. Again, nothing bad or deep but it really bothers me that I need to do constant maintenance to keep it out.

    Also, sorry about the title misspelling.

    Re: Casting Iron Table Saw Rusting

    Yes - I have the Ridgid contractor saw as well, I imagine the same one you're talking about.

    After the winter, the top was covered in rust.

    I got a two part cleaning product from Sears up on Merle Hay (this was a year or so ago) First part was a cleaner and the second was a preventer.

    White bottle with red lettering. I'll try and dig up the brand name. The two bottles came as a package and ran about $25.

    As for the mitre slots- I used a rag and flathead screwdriver and some elbow grease. Make sure to check on the corners, sides and underside as well. Rust "travels".

    Anyway, worked great for me. Really haven't had a re-occurrance. Threw some on my cast iron jointer as well, and it's been fine.

    Here ya go. Sears says they have it in stock at both DSM area stores.

    Hope it works for you.

    Boeshield T-9 Rust Protection Cleaner - Model T90128 at Sears.com

    BTW - I came across it after doing some searching and finding it recommended on a few wordworking sites.

    Re: Casting Iron Table Saw Rusting

    Of course it's happing in a spot that will be hard to polish.

    I wonder if something like T-9 would work better. It displaces any moisture, while the paste wax will trap any moisture, allowing the rust stains to return?

    Re: Casting Iron Table Saw Rusting

    Thanks guys. Two recommendations of the same thing is good enough for me. I'm going to pick some up. I need to get to Sears anyway to return one of my Lithium drill batteries that quit taking a charge.

    Thanks again.

    Yeah, growing up on a farm, we had "real" tool laying all over. And they did serve the purpose. However, I wasn't making cabinets then.

    You're making cabinets with a Rigid tablesaw? Ouch.

    Re: Casting Iron Table Saw Rusting

    Boeshield T9 is awsome stuff. Boeing developed it to protect aircraft parts from corrosion. Now, it's used alot to protect things that get alot of salt spray, like marine boat motors. It sprays on as a liquid, so it can penetrate into the pits and scratches in the tablesaw surface. It then sets up like a paste wax. Just make sure that when you wipe it off after spraying it on, don't leave too thick of a layer, or else it will dry kind of tacky, and the boards won't slide as easily on the surface.

    uh....yeah. Why? I did lots of research before buying my saw. The fence is fantastic. I can cut rip 24" wide. The fence fastens down tight with the flip of a the wrist and measurements to the blade from the fence are very accurate on the scale (I still measure with my tape, though). The motor is on springs that keep the tension just right and softens the "jerk" if a board binds up. It also has a wheeled lift system as an option that I bought it works really well. I can raise and lower the saw with just a kick. The surface is large and easy to work on.

    In my opinion, making nice cabinets is more about your blade than your saw.
