Attached file is of the FK20 bearing support I am purchasing. I have decided to machine a full Nema 24 to FK20 support out of a 150mm piece of 76mm x 76mm 6061. I reckon it will be nice and strong - also stuff like that always looks cool when people look ha

Hey but the dimension Dg6 is 57mm with -0.010 and -0.029 inside the table. So does this mean I machine my block out too exactly 57mm and the FK20 comes smaller for a press or tight fit? Or do I machine in a clearance?

Oh. The FK is on the boat I am pre making my mounts so when it all arrives I just bolt and run. I could wait I guess for it to arrive but where is the fun in that? Ha

The -.01mm is more than enough unless you have very heavy thrust loading, I usually do that type of Bearing fit between -.005mm and -.006mm
