Thanks. Excellent advice. The direction of sanding was most helpful.  I thought I might try afixing sandpaper to the inside of a piece of aluminum angle and using that to keep the part at right angles.  Anyway, there is much good advice in that video.  I learned a lot.

Thanks,

Dave

Dave;

 What I do if the divots and parting pin marks are on a flat piece is this . I put it in a jig made of the same thickness of Evergreen plastic .Then when I sand it is all flat  ,with no chance of rolling over an edge .

 Been doing it this way for years . I also use the adjustable pencil sized sander . This primarily for tight spots . Also if the pin marks are too deep you can use a craft punch and punch out a disc out of thin ( .010 ) and insert it in the hole and sand it to match the surface .

Very good thinking.  I was thinking of a jig but didn't consider allowing the jig to be sanded with the piece.

I mask with tape right down onto the area, within 0.10 inches, of the ares to be sanded.

This video proved to be extremely helpful. Thanks. Taping the sandpaper to an acrylic block and sanding in one direction only, improved results dramatically.
