Greetings;
I sent this yesterday, but it never came back, apologies if its a
duplicate.
I need to make a 1/8 roundover bit, those I can find on the net are all
north of $45/copy.
So I need a 1/8 diameter, nominally 1 long diamond coated grinding
tool, suitable for sharpening chain saws with
Short reply is - the THCUD does not work for servo loops but is designed
for stepper systems.
You will have to look at rolling your own control and for servos that
might take some doing.
The general consensus is that you axis of a plasma. Most systems use a
standalone THC system that drives

Lots of excellent woodwork was done before the invention of carbide

The general consensus is that you dont use servos on the Z axis of a plasma.

Perhaps there is a confusion about the size. I understood
that Gene was seeking a 1/8 DIAMETER tool, not a 1/8
radius tool.

Thanks for the responses. I figured it would probably work fine, but that

If you only need a 1/16 radius, why not just touch the corners of the plugs
with a bit of sandpaper. It will be a lot of fiddly work, but probably not
much more time and effort than what you've put into trying to automate it.

In theory, yes, but it would be a project in itself.
Personally I would cut the radius on the lathe then put in the
clearance by hand

Actually, I am not sure I did. Those look to be 1/8 radius, not 1/16 radius.
