Default The Chinese 9 X 20 Lathes

As most of you already know my current lathe is the Chinese made
Grizzly G4000. I've seen a few others here also have Grizzly and
Harbor Freight machines. They're great once you get them set up
properly! When you open that crate what your getting is basically a lathe
kit. All the parts are there, but the assembly work needs a little attention.
When I first got mine I cleaned all the cosmoline off everything, bolted it
to the bench that I had built a week before and leveled it up. Chucked up
a piece of 1018 cold roll stock and tried to take a cut. I've seen better
finishes on the foil balls that bounce off the back of your head in the lunch
room from time to time. :lol: So I set to the task of really checking it
over. .002 spindle run out. :x The gibb adjustments were sloppy, to
be polite. The 2 bolt compound clamp wasn't near rigid enough.

Grizzly's tech support line was helpful in adjusting the spindle bearing
preload. I made a new 4 bolt compound clamp based on the plans by
Steve Bedair
A rough spot on the ways was causing a taper. A fine stone took care of
that. They DO take some tinkering to make them as good as they can
be, but for the price they can't be beat!

Seriously, how many times can THAT happen in one day?

I have a Grizzly lathe myself. It is a G4016 and has been great so far, or at least for an untrained amature as myself. The first thing that I did with mine was to lose the cheap chuck that came for the tailstock and replace it with a Jacobs chuck. The second thing was to install a QCTP.

For the money, and for a HSM environment, I think that these machines can't be beat.
There is never enough time to do it right.¬* But there is always time to do it over!

Rick, forgot to thank you for the info on Little Machine Shop. I ordered 3 of the 39X4 six inch backing plates and they should be here the first week of August. I avoid the UPS Broker gouge by delivering to a friend in Detroit and he brings them up when he is here on business which is about once a month. It works well for small stuff, but for large items like 2 Grizzly 4000's I get my step daughter to pick them up with one of her Logistics trucks to bring it over. It is considerably cheaper with a regular broker and I honestly believe that brokerage fees for UPS is a profit center.
