the problem is..

I need to turn part with upper tool head when its turned to - 90degrees, because of large diameter.

So the thing is, that i can do all facing i need, but when i get to OD machining it wont let me to create a tool that is B-90 position. Because of large diameter i cant approach OD i need to machine if B is 0.

I know that this is possible via caps, just how?

Anyone got ideas how to trick caps and let me do this like i want to?
