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 ...

Other options for buttress. DIN | ANSI .. Either grind a tool out of M2

Lathe sound easier than milling it.

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 f
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.

That much stock tilt (30 degrees) in a 21" workpieces length, is well
beyond the z travel available on that gantry mill, not to
With current technology wood glues ( epoxy ) are often stronger than the

Another possibility would be to make a good approximation to the desired
buttress thread using a ball endmill. Mount the stock horizontal on your 4th
axis and make multiple passes with the ball endmill with each pass being
deeper and nearer to the vertical wall of the buttress thread. Of course the
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.

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 c

Small ball endmills are available for reasonable prices. See
https://www.ebay.ca/itm/154526476320 and
https://www.ebay.ca/itm/152182318115 for examples from a vendor with whom
I've been happy. Of course tiny ones may have insufficient reach to get to
the bottom of your threads.
