I need some help. Today I was doing some buffing on my 1018 and went to hit the stop button. There was a discharge of static electricity and now the lathe only turns really slowly. Have I zapped the speed potentiometer or have I done something more serious. If it is just the speed pot is this something that I might be able to puchase at an electronics shop? Any ideas would be greatly appreciated as I need to get this up and running asap.

Thanks
Michael

I dunno, but I am curious.
 
Without doing more testing, my guess is that you damaged some electronics in the VFD. To prevent something similar again, ground yourself to the lathe frame before touching the controller. If the lathe is still in warranty, contact your vendor about repairs. The VFD should have been more robust than that.

Thanks Charles. The strange thing is that I was buffing earlier in the day and had no problem with static. Hopefully Oneway will get back to me tomorrow. I went through the instruction sheet provided with the lathe and reprogrammed the drive and everything seemed to go fine but no change in the lathe speed.
I may become the world's slowest turner pretty soon but I don't think a catch will put me in any danger:biggrin:.

I'll post when I get things working again as I gather enquiring minds (or at least one) want to know.

Did you unplug the lathe and wait about a minute then re-plug and give a try? Also my powermatic has a reset button.

Update for anyone interested.
Well It wasn't the speed pot that was the problem. Took the drive etc. to Oneway this morning and Kevin is packaging it up and sending it to the manufacturer to figure out why it is stuck in slow speed. That means at least another week with no lathe. :mad:

Awe shucks, Michael. I know how you feel. I had to wait until I sold some pens in order to replace a failed tail stock and spindle. I try to keep personal/household monies separate from pen turning.
 
Thanks John. I had just managed to find the time to get back to turning about a week before this happened. Before that I hadn't turned since early October. Frustrating to say the least. We've also had our main computer in the shopnfor about a month and I'm starting to think we may have to replace it.

I try to keep finances separate also but haven't been particularly successful since I refound pen turning:eek:

Yes, it is hard to control the "checkout cart" once we start to shop.
We had a small wind fall that allowed us to pay off all our bills. We start new and my turning pays for itself or we give it up. I have always done well in the past but have had to help pay for taxes, insurance and other things to keep afloat. It is also used to keep a hidden bottle of JD in the workshop of which one or two shots a week are consumed. The cabinet is empty at the moment and will stay that way until more funds are collected. Ain't life a hoot?? :laugh:

Up and running at last

I finally have my lathe working again. :biggrin: Only cost me close to $400!:eek: Unfortunately they couldn't repair the drive.Now I've got to get busy and get some things turned and sold to help pay the bill.

Michael,
Many years ago, I went to work for a forwarding company that was part of a moving and storage company... seemed like we were an after thought, so wound up in a back office that had cheap cheap nylon carpet... just walking across the floor would build a static charge sufficient that you could hear the pop and see and feel the spark everytime you discharged... in the beginning it actually hurt when I discharged that static charge... I got into the habit of slapping the side of a file cabinet before I reached for the drawer handle. When I retired almost 25 years later, I still did that...even though I left that company in 1976... and on occasion still find myself doing it now after being retired for almost 6 years...

When I buff, I've found I also get a static charge and have begun to do the same thing... slap something metal to discharge. My lathes are all mechanical speed control, so no worries about zapping any electronics, but it's still a little surprise when the sparks zap off my fingers to the lathes... the slaps discharge without the pain.
 
Yup, I know what you mean Chuck. I'm now being very careful and doing the same thing. Just got to train myself to remember each and every time.

It has been really great the past 2 days getting back to the lathe. I was getting a tad grumpy:mad:! since I'd just ordered some Alumilite, a Rotondo, some new blanks and Alfred was sending me a box of blanks from the Bash.

Before the lathe went our computer also died. I'm a diehard Mac guy so a few bucks there also. They tried everything they could to fix it but in the end it was purchase a new one.

Unless your electronics are hardened, they are very susceptible to static discharge. I learned to carry something metal in my hand to allow the built up charge to go to ground without going into my electronics. When it jumps from the key/screwdriver to ground, no pain. Just be sure that the electronic device is at the same potential as your ground. Or you can always get a static strap from electronic repair shop and wear that. No static build up.
