OTOH, a cable system is probably the easiest to pull off, and tricky enough to get right.
I'll be following your progress with interest.

No the coarsest is 4 TPI then 4 1/2, 4 3/4, 5, 5 1/2, 6, 6 1/2, 7 then 8 starts on the same row as 4 again but with the first sifter going from A to B.
The quick change gear box is basically two transmissions one right after the other.
The first one a 5 speed the second an 8 speed.
You're over driving the lead screw to cut anything below 8TPI.
8TPI is direct drive in comparison to the head stock, they both rotate at the same speed.
The first thing I need to do is build the fire box/pit then build around it and I will use the screw mechanism to raise and lower the legs.
Not only can you adjust the height you can make the legs be in contact evenly with the surface they are sitting on, 'no wobble.
