The Incra Miter Gauge 2000 has an unusual screw at the
pivot joining the top and bottom plates to the slider.
It has a 3/8" shaft for maybe 1/4 of an inch and the rest
is a 10-24 thread that screws into the slider. I want to adapt
this gauge to a sliding table and need a longer screw like this. Is
screw commercially available? I need the 3/8 thickness
on top because that's the diameter of the holes in the
two plates and I don't want to change the thread in
the miter gauge.
