sawsmith 2000 question

[houlerhoule]

Had the same problem a few months ago. I thought it might need a new starting capacitor. Removed the motor and brought to a local electrical shop that repairs and rewinds electric motors. He said he had worked on several other SS motors in the past and for the same complaint. He found that too much sawdust gets into the motor and it won't run. Needs to be blown out with air. My SS was manufactured in early 80's so I asked him to put new bearings, starting capacitor, and check the rest of motor out. He also found that the wiring bundles in stator were loose and needed to be re-tied. Cost me $35.00 for what I considered a complete overhaul.

I'll try to post a pic of the relay tonight. I ran all the numbers on it and came up empty handed, I've had real good luck simply googling the model number of a component and finding a replacement, just not this time.

As long as I have the motor removed I'll sneak out of work this afternoon or tomorrow and run it across town to the local elec motor shop and see what they have to say.

I believe that was a common complaint and downfall of the SS2K. It had an open motor and dust would get in and cause problems.

Took the motor to the motor shop. Described the problem to the tech who said immediately that the problem wasn't going to be the motor, problem would be the relay. He turned out to be a fellow woodworker and did check out the motor for me, spent about 45 minutes on it. Clean bill of health, ran fine on the bench. My problem is finding a suitable relay. The Klixon 6CR series was discontinued years ago and no one can find me a suitable replacement, or give me the pick up and drop out specs on the unit to find something else. I've called distributors, Texas Instruments (who used to make Klixon) and Sensata who now own Klixon and have bassicaly been told that I'm out of luck.

I do, however, have a possible solution. A solid state relay. In talking with the motor tech he showed me a solid state unit that they use to replace the centrifugal switch in on older motors that can't be repaired or replaced.

Instead of switching based on the current draw of the motor (like mine) or the rotation of the motor, the switch on/off is based on time, ie 1/3 second, 1/2 second etc. I'm going back over there on Friday to pick one up and give it a try.

I've been tied up every night this week and haven't been able to tinker with the SS2K but Friday is my day off so I'll be hitting the motor shop. I'll post more information and pics as I get on with the project
