Drawing for machining platter to fit teres bearing

[3GGG]

Hi
I have my Teres bearing and 75mm acrylic, now I need to get it machined. Does anyone have a cross sectional drawing showing where the stainless steel part of the bearing fits into the platter. Something i can give to the machine shop y\to help avoid any stuff ups.
Cheers

Have you had any quotes? I am curious how much the platter will cost. If it is not too much i might be interested to get one too at the same time, it might help with a better price?

I managed to buy the acrylic for $110 and the bearing $310. Machining yet to be arranged but couldbe $$$ due to the tight tolerances involved.
