Is it perfectly straight? I am wondering if it slender enough to be whipping?

I have a customer who processes foam and the foam dust is corrosive.
They process the foam with saws in several locations in the plant and
they have become masters at using air blowoff and air pressurization to
keep the dust out of the machinery. I'd consider putting a small
blower in the ar

On another list, I have seen suggestion to use motorcycle chain grease if grease
is insisted on. Mainly because it does not collect the fine dust
particles like regular
grease does. It is designed for use in a very 'dirty' environment.

From the drift in this thread it sounds like you have an X2 using
stock screws. In my case I abandoned the stock screws and went with
lower cost rolled ball screws. I decided the X2 wasn't rigid enough to
justify precision screws. Of course at 5 tpi I get plenty of

I was dissatisfied with both the speed and the backlash so I
abandoned the stock screw and went to the ballscrew. I now arbitrarily
set the max speed at 80" per minute. During this change I upgraded to
the G540 drives as well. I haven't measured the force on the drill bit,
but can ea

Model Engineering Expo in Toledo, Ohio. We had a 10' x 10' booth

cutting wax and/or air), and some great, large-format photos of
various machines that run EMC. (No
Dale,
PMDX would certainly be interested in coordinating booths
with any EMC related presence at NAMES. We had a choice
site at the last show, but due to the move, all bets are off.
The sooner we can ask for a group placement, the better.

Depends how cheap is cheap enough. eBay is one source, I got my 8mm

Jack,
I'm in Lenoir City, TN. Within a Stone's throw of the I-40 / I-75
Junction southwest of Knoxville.
I am using EMC2 to run a 10 mm Derbyshire instrument lathe and a
Millrite vertical Mill with xyz and a axes.
Not exactly near Nashville but I have been there a few times.

Thank you very much kirk, i downloaded the package and worked.
