AS JIM SAID YOUR 7 cents is worth a million, and i will do like you said I was aware of the rounding as it occured when using my dremel to bring the pieces a little oversize and then final sanding, and probally i made it worst by using the foam backed sanding block, and i will absorb the res of what yo said, IT HELPS A LOT, this is what makes SOS WHAT A FORUM IS SUPPOSED TO BE. THANKS AGAIN Don
