Maintaining cast iron tablesaw top
Just a quick question to all. What do you folks do/use to maintain the cast iron top and table extensions of your table saws. Just got a Unisaw and want to keep that brand new look and feel on the top.
thanks in advance,
Jim

Of course the best thing would be to keep it at my house (haha) car wax..the good stuff works for me and my cheap tools
Oh Jim, you lucky dog you! Many of us use paste wax, though personally I'd not recommend car wax per se but rather a good furniture wax such as Johnson's or Minwax, or there's a bowling alley wax out there (don't remember the specific name). Some of us use the specialized spray treatments such as Boeshield or TopCoat. You'll get lots of input on this one, and a few cranky guys who tell you to do a search (just ignore them :-)

Jim don't listen to BG he doesn't know what he is talking about. You should keep it at my place instead.
But if that is not a option than as BG said a good car wax is all I use also.

For what it's worth, I didn't like the brand new look and feel of the Unisaw; the surface finish was too rough. I sanded it down (by hand) to knock off the high spots, and then used Johnson's paste wax. Smooth as a baby's butt now.
Be seeing you...

The talc thing is raising a vague, vague memory. There are some other uses for talc in woodworking -- can anyone re-iterate here. I can't remember (too much good food for the 4th!).forestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)
Talc does little more than absorb moisture. Wax keeps moisture out by semi-sealing the surface and acting as a repelant. Talc will abosorb moisture before it gets to the metal if it is completely covering the surface. It works well in conjunction with wax if you are not using the equipment or storing it for short periods of time. Talc can also be used as a surface lubricant on metals since its composition is such that it acts like millions of tiny ball bearings.

I think the best thing is a good furniture paste wax. Minwax, TreWax, Johnson, Butchers, all are good.
I would not use any automotive product. They frequently contain silicone and most contain water to make them easier to spread. Neither are good things to put on your cast iron tabletop.
Just read your reply about keeping the table saw top nice and shiney. You said that silicone is not good for it. Why? I have used it for years and have not seen any problem. Please educate me. Thanks.
Silicone frequently causes finishing problems with lacquer and varnish finishes. There are no benefits to silicone as a rust preventer or preservative for cast iron, so it is better to stay away from it.
Thanks. I WILL change my ways!
Does anyone know if TopCoat uses any silicone product? I have been using this for about 2 years now and I am fairly satisfied with it. The only negative is thatit doesn't last long. Living in Missouri, where it is hot and humid during the summer, I try to make it a point to spray down each machine before I go on a trip. This becomes a pain because I travel a lot. I was gone for a month one time and I came back to an ever so slight layer of rust on my table saw...I almost cried. :(
Does wax last longer? Any effects on finishing product if wax is used?
thanks to all for your responses. I to sanded the surface as well as having to file all the edges(because of burs) and got it soooo sweet. I am using Johnsons paste wax, but thought I had read a previous thread that had some people concerned about getting residue on wood and causing possible finishing problems down the road. I could not find the thread again. To Joe Fusco, I used to work for a guy with a PM66 and at the end of the day we would get in the cabinet of the saw, get out some saw dust, cover the top with about an 1/8 inch, then cover it with a piece of 1/4 inch plywood. Again thanks to all. Oh, sorry I think Iwill store it at my shop!

Joe,
Thanks for the response. I have been wondering about Top Coat. The manual that came with the saw has Delta suggesting that you rub the top down with 0000 steel wool and WD40, degrease the top and finish with Top Coat. I don't think I want WD40 anywhere near my saw top.
By the way, I've always admired your pretty amazing grasp of Trig. I do mostly custom cabinetry and purpose built furniture(entertainment centers, executive desks etc.) but I also do curved stair work. I find the actual building pretty straightforward but the math can be a struggle.
thanks again, Jim

The main concern I've seen expressed about wax involved waxes with silicone -- e.g., car waxes.forestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)
Living in Florida, sweaty hands are my biggest problem. Wax is no help whatever. I keep a towel nearby for hands, but then it drips off my nose! Ah, life is a bit...ah, beach!
When the top gets so ugly that I can't stand it anymore, I get out the sandpaper and polishing compound. Don't know of anything else to do.

Dave, what grit of sandpaper and type of polishing compound do you use? Thanks, Bill
Let's see.... Step 1... Degrease
Step 2 Use a FINE file to remove any sharp edges. Don't go crazy here. Just make sure there are no sharp edges.
Step 3 Sand the top... Use WD-40 as your lubricant and 100 grit wet/dry sandpaper on a block of wood with a layer of felt. I scrub North to south, then east to west, NE to SW, and finally SE to NW . Wipe the table top clean.
Step 4 repeat with 200 or 220 grit wet/dry sandpaper and clean off
Step 5 Repeat with 400 grit wet/dry sandpaper and clean off
Step 6 Use 0000 steel wool and paste wax to finish the surface. I usually apply it in a circular pattern. Let it dry and buff it with an old t-shirt. I like Johnsons Paste wax, but ANY good paste wax will work as long as it DOES NOT contain any silicon.
Step 6a Repeat just then WAX part every 2 or 3 weeks or as needed as dictated by your work schedule or high humidity weather
Step 7... Pour a cold glass of your favorite beverage and enjoy your work.
No secret, just some plain old elbow grease.

FYI -
I accidentally left a small piece of PT lumber on the table saw on evening. The next moring, it left a rust stain, even though I re-coat the top with wax every month.
From the factory I cleaned the top with mineral spirits & 0000 steel wool to remove the grease. Monday is my designated tool maintenance day. I apply Johnson's paste wax with 0000 steel wool. If any stains rust etc get on it I just go over it lightly with the random orbit sander with 400 sanding pad to polish it back to new. Keep the sander moving. Johnson's contains no silicon. Delta recommends a weekly waxing of the table ane fence. Have fun, Jim
