Are these running single ended? Have you tried it with the spindle
running?

I view this as a mystical black art.
For me, the basic idea is to
(a) support the part to prevent damage when it separates from the
parent, to stop it catching the cutter for example. In that case,
or setting it up.
How does one know what size tabs and how many?

Speaking of backlash. My tiered old Bridgeport has about 0.002" of backlash
in the ballscrews. So if circular interpolation is used there is a small
bump at each 90 degrees of the circle. But if I make the finish pass first
clockwise and then repeat counter clockwise the imperfections are much
You might try the run again without the backlash compensation in LCNC to
get a feel of what it is actually doing.

Springs might not be the best way. The common way to tension double
nuts is to

You might bear in mind that ballscrews which use a single nut don't have
zero backlash. They do have consistent backlash over the length of the
screw - until they wear, of
. So there are
other issues before I can start on the Ball Screw Conversion.

First, if you have a lot of backlash in the X & Y movements, you should
avoid climb milling. When the cutter grabs the work, it will take up the
backlash (and maybe break the cutter)
As for the way you have the work in the vice, I would ditch the round
stock, and clamp it lower in the vice. I
Hi Dave,
Things have gone from not too bad to worse.
My Drill Chuck in the TT Holder and a pencil held for doing the tracing has
vanished. Can't find it anywhere. I suspect it's now with the Dr. Who "Key
to Time" box set along with a couple of other DVD movies that also vanished a
few
close to round hole.
Anyway. Lots to learn.

Was the same tool used for both profiles?

Hello John,
Have you found the problem already? I just came to this and my thoughts are
may be you accidentally used another coordinate system with different
offsets for the hole?
