a simple jig seems easy enough to make - I keep meaning to do it and get
distracted - the premise being that making it is "fun" and buying it is
"not
fun" - with that caveat,
get threaded rod, either 1.25 or 1 X8 so you can attach your chuck to
it -
get a couple of nuts to make a "head stock"
now as you turn the rod, it will move laterally in the nuts, making the
proper motion for cutting threads.

Now, get a 60 deg edge cutter and a cheap HF die cutting drill - mount in
a
dovetail type slide so you can align it at the proper diameter, fire up
the
drill and rotate the threaded rod to cut threads into the object being
threaded.
===========================

Here's you another opportunity for an additional sideline (to go along with
your face plates and vacuum pumps). There should be a market if the price is
rock bottom like the other items.
