I am looking for advise on how to cut a 1/4" radius in a 6" piece of
wood. I am aking a jewelry box and it calls fo a couple of scroll type
curves wiusing a 1/8" blade. I have been trying for two weeks and I
cannot get the saw adjusted properly and the blade keeps moving off of
center and free of the guides. I have made the cut in a 3/4" piece
andit works just fine. I don't know how to get around the thin blase
cutting though the thickness of the wood. any suggestion would be very
much appreciated.

Your description was not so detailed as to fully understand just what
you are trying to cut.......but if this is an outside radius on the
corner of a block why not instead cut it square and then come back with
a quarter inch rounding off bit in a router on a router table.
