I've made just such a jig. I started with the
frame of a SA400
that I picked up scrap. I then made two blocks of aluminum
Thinking about it, the advantage of the SA400 is that the upper part of
the index sensor, and thus the upper die block after modification, is on
the clamp arm. Taht means the 2 die blocks are moved apart when you
insert a disk.
The disandvantage of the SA400 is that because the 2 die blocks would
move apart, they may not align again perfectly. And the other prolem is
that the doors tend to reak if your'e not careful.
I used drilled detents on the flywheel, using a 10
hard sectored
disk to index with.
Having got a proper dviding head (!), it would be very easy for me to
either drill holes or mill notches in the pulley.
