First problem with Nova DVR-XP

Actually that is a common problem, it can be triggered by using the index as a "stop" to hold the lathe-shaft to remove chucks.

I'm guess you mean the spindle lock?

I've had mine loosen twice so far, no big deal, really.. I noticed that the knob rotated a lot more and that it was higher on the headstock than usual... Removed the backing plate screws, rotated the plate a bit and got a wrench in there to hold the nut while I hand-tightened it with the knob.. Only a temporary repair, but my Hand wheel didn't want to come off and I didn't want to force it, so I couldn't remove the end plate..

My fault that it's too tight... I put the ram rod through the handwheel and against the headstock lock when I'm removing chucks, so I've really tightened it, I guess..

I used to own a DVR. Sometimes the top of the index pin used to get clogged with debris and had to be taken apart and cleaned.

Also, using the index pin to lock the shaft when unsticking a really stuck chuck can break off a tooth from the index wheel. I know because I did that. Teknatool told me that they would replace it, once. They recommended not doing that again and said it would not be covered under warranty a second time.

I just put the rod through the handwheel with the long end toward the front and gave it a rap with a mallet. This was the ring on the spindle that was loose, not the top part that engages it. The ring slides onto a key so it did not actually turn, just slid sideways a bit.

Guilty. But it is a robust system and is used for a lock, not just an indexing pin.

But, the manual says that the spindle lock can be used for putting thing ON the spindle, but NOT removing them... Yep, I actually RTFM ;-]
