Back in 2002, my wifey asked me what my dream lathe would be. Being kind of frugal in those days, I showed her pictures of small Novas, Jet, etc.
Last summer I got some maple logs, with spalting here and there, so I finally got around to cutting them up to make some nice bowls. Had my first one just about ready to do the last step, finish sand and then finish the foot when I pulled out the on/off button, and….....nothing. My heart jumped and I thought – “I cannot afford this…”
First I checked the spindle to make sure all was free. Then I looked inside the belt chamber to see if the belt had finally broke. Nope. Then I looked at the back on the readout to see if any funny codes were on the screen. Nope, just the percentage and the word “STOP” which is always there when it is not running.
By then I had settled down a little and went into troubleshooting mode. What usually breaks? Usually the things that are used the most, like switches and speed knobs, things like that. I used to tell my technicians in the factories, forget the VSD’s, check the buttons first!
I unplugged the lathe, and removed the plate holding the start/stop button and speed control. Clean as a whistle in there. Hmmm. Got out my multimeter and checked the one single NC contact on the start/stop button. It was not working. I breathed a big sigh of relief since I knew a electrical supply house was just down the road, and they carry that brand. Maybe ten bucks.
