Also, how does one know how much to file away?
Like if you have one tube that has diameter A,
and another has diameter B, and A B, and you
want the second tube to be at an angle X from
the first?

If we return to the lathe guys they have
a small thing with rods that can be pushed back
and forth to form a pattern, perhaps something
like that can be used to do a template if it is
difficult to compute?


I made a frame plate:
