Why do you need to remove them?
Most of us have scratches on our saw tops from normal use.

You can use 0000 steel wool or green dishwashing pads attached to looped sander with mineral oil. But really, minor scratches should not be of any concern.

If you don’t have a few scratches (or several) on your saw top, or a few rust spots, then you’re not using it enough…That’s like having a brand new guitar with no scratches…if you don’t have any, you’re not playing it enough…

I agree with above, normal to get some scratches. No cause for concern.

I was dadoing with standard blade on day 2 with my new sawstop and have 5 or so scratches from a screw that i hadnt noticed protruding a mm or so a few inches to the left of the blade. It was a horrible feeling and still bothers me a year later but its a battle wound and doesn’t effect performance

Tools are made to be used and abused, if they look scratched up that means your using them. Nothing lasts forever, enjoy it while it runs.

Sounds like it’s time to replace the saw.

It’s now officially broken in. Like the first time I accidentally sawed into my workbench.

The more scratches you add the less apparent they’ll become.

I remember how pristine I tried to keep my first and only workbench…. for a week. Now it looks like I dragged it behind a truck and swung it into a Minwax plant and hit a guy drinking a vat of coffee and he bled all over it and stuck a few sheets of self adhesive sandpaper to it that never got fully removed.

I like my bench so much better now.

Ask yourself what sort of shape your screwdrivers and pliers are in, then remember it’s just a tool. ;-) There will be others….used is not abused.

RJweb,

I too have wondered about the cause of those minor and superficial scratches that a mysteriously appear but until your post I gave it no further thought. I suppose some scratches can appear as a result of setting a hand tool, measuring tape (especially if the tape measure rests on its belt clip), or anything other tool made of steel on the cast iron, but I doubt that is the cause of most scratches I observe. When I looked at my table saw, which I have used for over 15 years, there are enumerable scratches that run parallel to the direction of travel of the lumber.

But thinking about it my best guess is that they result from fine abrasives embedded in the surface of lumber. The jointer sees the rough lumber first. Even though I make an effort to at least brush off dirt and debris with a horsehair shop brush, grains of minerals (like fine sand) could still be left on the surface which, as the lumber is face planed flat, can scratch the cast iron.

The other source of abrasive could be grains of abrasives dislodged from sand paper and which stubbornly cling to the surface of a board, even if the board is brushed after sanding. Accessories and jigs used on the machine could also conceal these fine abrasives.

Although I tend to use only domestic hardwoods, my understanding is that some exotic hardwood contain abrasives within the wood it itself. If true, I suppose these exotics could scratch the top.

Like most of the posters, I do nothing about the scratches other than keep a coat of wax on the cast iron and try to keep my lumber brushed off. I figure by the time the cast iron becomes dished out enough to affect the tool’s performance, I will be lying stone cold dead somewhere in the ground and it will be someone elses problem.

Have your say...
