Bad machine work or am i over looking something?

rolled all the main studs on a plate of glass. there all straight.

I got thrust clearance by forcing the crank over with a screw driver and a hammer. torque cap and then releasing screw driver.

As soon as i unbolt the cap, the clearance go's a way. so i know i'm bending or flexing the stud to get what i want.

Not happy with this. Will be taking the cap to my buddy to have the hole milled .016 or so larger in the direction i need the cap to move.

The main cap bolts are .445 and the stud are .496 . So a .050" larger hole would allow the cap to shift, just like it could with the bolts. but i thing i will have him just take .016 on one side of the hole or make it into a small oval hole instead of a round one.

The problem is that he can't get to it for a week...........So my build is on hold, again.
