OK - well Kondia got back to me and said that is the only print they have on file for that part.
I had a thought on how to accurately measure the hub and I think it worked out OK. I bolted the part to one of my 1-2-3 blocks and then used gauge blocks to measure the distance between the two surfaces. Stupidly however, I have left the bit of paper with the measurements written on it in the shop
To measure the counterbore, I used the table of my drill press and a dial indicator mounted to a rack and pinion adjustment screw that was salvaged when a lab at the uni was having a 'throw out'! I had no luck however, as I couldn't get consistent readings on the DI. I think it needs a service, as I couldn't get it to repeat its zero point.
Here is a picture of that set up:
Bob - I had thought of using glass and I also got a lump of granite bench top given to me. However, that feels quite rough to the touch.
