Ron, you can get good files from Woodcraft, and also Enco machine supply, one of the files you will want to have is a #49 Nicholson wood rasp, a little spendy, around 40 to 50 bux, but well worth the investment, this rasp cuts wood instead of shredding it!, do a search for the 49 and you may find it as cheap as 29.99 on ocassion at certain supplers
