Hi
I'd go for something similar to the picture, but simpler.
Make the two cylinders and use a piece of angle iron for the sensor support.
Two holes for the bolts to go through. Offset so that the side of the
angle that is parallel to the shaft (and the bolts) clears the outside
of the round casting. Grind/cut from the middle of the other side of the
iron to clear said casting. Or make the cylinders the right height so
that the side of the angle iron fits between the flange (on top of the
casting) and the disc.

I often have trouble coming up with simple solutions.
Attached the photo of my encoder disk made from aluminium so slotted or reflective sensors would be required. My first idea of a clamp around the casting to hold the sensors really didn't work out.
The bolts holding the upper casting down are 10x1.5-35mm bolts and there's a flat machined area in the casting for the lock washer and bolt head. It's really hard to determine exactly what the bolt circle is but a guess of 120mm between bolts creates roughly 84.8 radius circle.
What if I turned out two spacers? Clamped them in place and then welded a bracket to them. Or even just a curved piece with much larger holes clamped down to allow some tweaking for fit. Then maybe spot weld in place with final welding off the machine.
Then on this plate mounted the sensors.
Good idea? Or also doomed to failure?
Thanks
