Being a machinist, I built one at one point, but even though the drum ran true within a couple tenths of a thousandth of an inch, I could never get the abrasive joint to not leave marks of some sort. Perhaps I was being too picky.

I might try again, when I get the zillion things that are more important beat into submission, but this time I'm going to try an abrasive belt running over a stationary platen, so that there is more than line contact with the work.

Didn't think of winding the abrasive strip on in a helix, as one of the on-line sites suggested, perhaps that might be the answer to the drum setup--but I think that the belt stands a better chance. Commercial belts are made so the splice is slightly thinner than the rest of the surface.

Shouldn't be such a problem for me-- I have an abrasive personality--right Woodie?


Fix it again, Mr Gates--it still works!"
