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.

Make some wooden guide blocks. Maple is good but any hardwood
will do. Before adjusting the gap move the blocks forward so the blade
will be trapped entirely within the guide blocks. Set one side block so it
just touches the blade plus a smidge. Now with the saw running adjust
the other side block so it is snug, but not binding, on the blade. The set
of the teeth will have carved out a channel for their clearance. Repeat
for the bottom blocks. Wax the blade by touching a candle to it while it
is running. Now make your cut using very little pressure and go
sloooooooow. There is not much room between those teeth for sawdust
and you need to let it clear out. 6" is really thick for that tpi count.
You may need to increase the blade tension a bit too.
Good luck.
