Jerry,

OOPS, just reread your post.  I marked the slip tube on the inside then
grind and repeat, repeat, repeat...  It usually takes more time to make
the slip fixture than the part.  Then, after making a production part,
the marking fixture may have to be tweeked, or maybe even start over
from scratch...  It pays off eventually if the quantities are good enough.
