Default Well, let's talk about my new DVR

Well, I got my first chance to turn on one at our last club meeting. I
was demoing bowl turning. It is a nice little lathe.


"Little" is a relative term, Reed.. lol

Pretty smooth, and does a good job of keeping its torque for a smaller motor. Most of
my turning was on a PM, and now I have a Robust. Smoother than my big
lathes, no. I found the speed increase/decrease button can be memory
set for certain speeds, and that would be faster, but a dial is easier
for me.

Yeah.. I've gotten used to it and have pre-set my favorite speeds, but would
prefer a dial or something...
Being my first DVR, it's not a problem, though..

This DVR was on the stamped metal stand. Turning an 8 inch
bowl blank at 1000 rpm, it did vibrate a bit till the blank was
rounded. Part of that could have been an uneven floor, and/or it
wasn't leveled in place.

For sure... The metal "universal" stand sucks... Universal usually means not bad
for most things and not good for anything, IMO..
Did the lathe you used have the bed extension?
I've heard that it vibrates less with the extension in place..

I really wanted the cast iron legs, but that would have required a 30 day wait
for them to be shipped from the manufacturer, and I'd already been waiting for
the lathe for 2 or 3 years..
Using 20-20 hind sight, I should have ordered the legs and set the sucker on a
bench until the legs arrived..
Another factor was a time window in which a friend was coming down for a visit
and he lived a few miles from a Woodcraft store.. Not like I can just order big
stuff shipped here..

I added 200 pounds of sand and it helped a LOT..

Getting the shavings out from in between the ways would drive me nuts, I don't know why they have the
bed sitting flat on the stand with no clearance under it. Maybe because of the bolt together ways which are in 2 ft sections. A good
lathe,. but not done the way I would do it.


The Nova's spindle was about 2" lower than the spindle on my Jet 1442, which I
thought was strange on a 16" machine..
I solved both problems by adding about 1 1/2" of pine 1x4" under the mounting
points..
Raised the spindle height and adds "shaving removal" room..
I'm assuming that this wouldn't be a problem with the cast iron legs..

I was told (here and by Nova) that because of the design of the motor and it
being beltless, that 100 rpm was as slow as it can turn.. Not an engineer, but I
believe it..

In general, I'm very happy with the lathe and it's features, except for the POS
stand..

I agree with the 10 rpm as a nice speed to have. I had it on my 3520A,
and had the converter tweeked on my Robust so it would go that slow.
The converters on the other lathes can be done that way, but get this.
This has been changed. The PM now shuts off at 50 rpm. I could never
sand my warped bowls out at that high of a speed. I contacted PM to
ask them about changing the B models so they could do that. Their
comment was it could be done, but you would have to send the converter
back to them so they could do it, and the warrantee would be void.
They said excess heat would destroy the motor. Well, I sanded out
several thousand bowls at that speed on my old PM, and a thousand or
so on my new one, and the motor doesn't get any hotter than when I am
turning. There was a discussion about this over at the AAW site. I
think it is bull. The converters can be tweeked in all sorts of ways
for higher or lower speeds, and torque, and other things only an
electrical engineer would know or care about. They just don't want us
messing with it.

I have had my new Nova about a month now and have done half dozen
projects so far. I can't believe how smooth it is. I can get a finish
off the gouge that requires very little sanding. Never could do that
with old 1642 Jet,or any other belt drive machine.


I don't get anymore shaking with an out of balance piece than I did with
the old lathe. The lighter weight of the Nova has not been a problem, in
*fact is an asset.


It's Derby time here in Kentucky, so my most of my time has been devoted
to lawn care, emptying out the greenhouse and planting the flower
gardens. So my pride and joy of wood turning is getting a little rest.
Give me a couple more weeks and the shavings will be flying again.


I would certainly recommend the DVR to anyone that is serious about wood
turning. It has a smaller footprint, great speed control, offset banjo
and it even sounds good. I could go on and on.

The only thing I would have liked to have is a bit lower RPM, but I can live
with 100..


* There are times that 10 rpm ish would be nice
