The easiest way is to sandblast it. If you can't do that, try a needle scaler.

Sandblasting is how we do it too, unless its something that needs to look really nice, then we buy cold roll. Flap disc's in a grinder seem to just polish it more than removing it. A hard wheel will take it off, but it screws up the finish doing it.

I have used a needle scaler before, but didn't have much luck. It knocked off all the loose stuff pretty quick, but wouldn't remove all of it. I have heard that if you sharpen the individual needles that it works better, but leaves little pock marks all over the metal.

Hot rolled sucks, I use a 50 grit grinding disk, and follow up with a roll loc medium disk.

In the past year of building my T I have had to remove tons of mill scale, and the best thing I have found is one of two things, both similar products. Some people have described them as rice cakes, and they are plastic discs that either have a 1/4 inch mandrel formed in so you can use them in your angle die grinder, or, they come in ones with a 5/8 threaded hole to go on like a 4.5 inch angle grinder. The second one seems to work the best, and even Home Depot sells them. I think Norton and 3 M make them.

Takes the mill scale of very easily, and leaves a nicely flattened surface, not all marked up.

That scale is real hard to remove, as it is rolled right into the steel, so here is a sure fire way to loosen it up. Finish paint right over it. Within a few days, it will start peeling off in sheets. Then you can sandblast it, and do it right the second time.

No I got cheap.. he wanted 275 bucks to blast the frame front axle and rearend. I was thinkin that was plenty high. I may go out in a bit and take a pic of the frame. Its almost done and even if id have had it blasted i had work to do with the grinder so im thinnin its better this way. I wiped some kroil on it cause ill prolly take a break till after memorial weekend and im tired of rust. Its lookin good though.
