I agree, John.  Especially after trying to make it work for four tubes.
However, I am working on an alignment concept that would not require such
accurate and expensive machining.  Same sort of concept that Tracy Crook
took when he designed his gear box, tight is expensive, loose is not {:>).
Will have to wait to see if it works.
