Can someone help with information or experiences on repairing my old Rockwell 12 RAS? (Ser# KU2439). I purchased the saw from the state government surplus warehouse. I have not started to repair it yet. I thought someone might have already repaired one and have some advice on where to start, where to find manuals, and what to problems to look for. The saw is mechanically sound, motor is can be turned easily by hand and the bearings feel fine, but the motor does not seem to get any power. Thanks in advance for any thoughts.

Find out if the motor works before doing anything else. Try doing a little electrical work. It may just have a problem with the switch. I have some experience restoring old RASs. If you get it to turn on, let me know and I can give you some other pointers.

-- Happy woodworking!

Thanks for your help. I downloaded diagrams from the suggested website. After a bit of electrical testing, I lucked out and discovered that the main switch was bad. I disassembled the switch and found it was full of fine wood powder. I cleaned the switch out, polished the contact surfaces, reassembled the switch and reassembled the saw and it works great.

Have your say...
