I've been happy. Of course tiny ones may have insufficient reach to get to
the bottom of your threads.

It is not the epoxy that is so hard. It is the filler they mix with the
epoxy. Many times it is a kind of glass, not unlike what they use to make
sand paper. Other times they mix finely ground bits of steel.
I used to use a brand of epoxy that sold bottles of pure resin and cans of
filler. I

I won't promise it does. It's been a while since I last played with it. Even
if it doesn't, it may be possible to pretend you are machining a slot in the
X-Z plane and use that for a lathe profile.

Booting from an ssd is now supported by the pi but you need to configure the

With current technology wood glues ( epoxy ) are often stronger than the
wood which allows one to machine short sections and glue them together
for a composite piece that is as strong as a contiguous part. I think
Gene is talented enough to make a live axis for his lathe that would do
a bang

That much stock tilt (30 degrees) in a 21" workpieces length, is well
beyond the z travel available on that gantry mill, not

Freecad "path" workbench generates g-code toolpaths. You can paste your
openscad source code into freecad with the openscad workbench.

Greetings all;
Thread milling would be a good approach except that I doubt that Gene has
18-inches of Z-clearance on his small mill to thread the length of his desired
screw plus spindle clearance to mill to the table might be an issue.

First off this is a really simple design. I think it could be done on a
normal manual lathe with no CNC. Just use the correct thread cutting gears
to drive the carriage.
The trouble is that writing g-code by hand or turning handwhels with no
computer breaks the chain that goes from your design
Other options for buttress. DIN | ANSI .. Either grind a tool out of M2
or equivalent or go shopping for inserts on the web surplus sites. They
won't be cheap but a bit less hassle.
Single point thread mill??
Lathe sound easier than milling it.

Alternatively one can tilt the stock rather than the head which I believe is
Gene's plan.

If you can tilt the head at an angle, then something as simple as "G1
X300.00 B30.00" will do it, depending on how you have configured the B
axis. If you can't tilt the head, no amount of GCODE will help you.
I'd just do it on the lathe ...
