I've just made a similiar if smaller adaptor plate for a 6" RT. I haven't used it in anger yet, but how do you get the chuck aligned with the axis of the RT?
My plan was to bolt the chuck to the plate which will be fairly close to centred, and then loosely bolt the plate to the RT and spin it, while indicating against the edge of the chuck and shifting the plate according to the reading. My theory is that once the indicator reading is constant, the chuck will be aligned with the axis of the RT, even if the mounting plate isn't.
