I have an old Craftsman 12" direct drive tablesaw (blade mounted on the motor) and need a manual. There is no indication of a model number anywhere other than on the motor. The motor model number is KK48BB-107 and its part number is 62254 & mfg. number is J6990. The shaft is 5/8" and I haven't found 12" blades to fit. The saw is labeled as a 12" saw. ***** has been no help.
go to a large hardware store and ask for arbor bushings. you should be able to get a bushing that will convert the 1" hole in the blade to 5/9". I was able to get 1/2" to 5/8" bushings at a large Ace hardware and they had many different sizes in stock there.
