First problem with Nova DVR-XP
 

Noticed that the indexing pin would not drop down completely to lock
the headstock. I looked through the inspection window and saw that it
was riding on the top of the indexing ring. Unscrewed the handwheel
(it is a left-hand thread), and removed the end plate. The set screw
had completely backed out of the indexing ring, allowing it to drift
outward about 1/4 inch. I replaced the setscrew using some blue
loctite after dropping the setscrew and having to find it with a
magnet. All is well now.

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..

First problem with Nova DVR-XP
 

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 ;-]
