I have these little multi threaded adapters, you can just
see the top of it spinning around in the previous post.
It has three different threads:

5/8”-27 Outside
3/8”-16 Inside
1/4”- 20 inside

It also has a slot on both sides big enough for a US quarter.
Should be a fun challenge to build this one.

Over time my method evolves as I keep trying to improve, simplify and increase accuracy.
This is my most recent evolution, following engineering drawings as closely as I can.
