Anyone got a site or place where there are plans or drawings that show
something like a sine bar machine or other style that wouldn't be that
hard to build?

Am thinking of building a flintlock or percussion rifle all from scratch.

Once I figured out what he was doing, I saw how clever that method
is. And adaptable, as in "one can easily change the twist, without
having to make a new guide."
The fun part is that now I have an idea for how to put spiral
'carvings' on wooden banister post. Now all I need is the lathe, and
the space to set up. Oh, and a banister which needs posts. B-)

Here's the lathe you need:

A Rose Engine can create extremely complex geometric patterns like on
the back of a $1 bill.

An interesting question, I remember when I grew up in the US in the
1970s seeing a film several times of a working museum, in
Pennsylvania?,Â* that preserved the techniques for making long rifles,
Kentucky?, and the main detail was about the rifling technique and
mechanics usedÂ* It didn't look high tech just required a bit of work to
produce the master screw which governed the rifling cutter.

The slow, tedious, manual method of gun making prompted several early
inventors to create automation.
https://en.wikipedia.org/wiki/Thomas...hard_(inventor)

Until around 1850 military contracts provided the only advance
financing and guaranteed demand to support buying new production
machinery. Combined with chronic labor shortages as immigrants headed
for the frontier, government rifle purchases were the first driver for
America's rapid advances in industrial automation. In 1800 we were a
backward third world nation, by the 1850's we were selling world-class
rifle production machines to Britain.

The ideas underlying the Industrial Revolution were originally French,
but England and then America provided more productive environments for
their development. AFAICT automation was suppressed elsewhere to
protect traditional jobs but that may not be the whole answer.

An engineer from India who resented the USA and Europe's domination of
the modern world asked me why Europe had suddenly surged ahead of
everyone else, particularly India and China, and I couldn't fully
answer him.

One theory: the black death resulted in younger property owners, who could
foresee a long life ahead, and weren't inclined to be staid and conservative.
So, they innovated.

There are many reasons, some specious, some plausible.
