Hi all,
I need to add a degrees readout to a large rotary table.
The table is around 1 meter in diameter, and I can only add the sensor to the outer rim, kind of like a trundle wheel.
My initial idea was to just setup a rotary DRO with a rubber wheel running on the periphery, but then I though what about the gearing?
The table is so large that I cant have a 1:1 wheel, so how to do it?

I dont mind doing a bit of electronic jiggery pokery, but Ive not done anything like this before...

all ideas and help gratefully recieved

Dave
