Hi Bruce,
That's a great offer. Thank you! Unfortunately I don't have a Mac but there is a trial version of Rhino which may work.
The design I had in mind was based on Greg Babcock's as shown here:

I like the design he uses on the 12 inch scope but I would be scaling it to a 10 inch F6. The only major change I was planning was to add a middle ring like Albert Highe does on the second scope on this page:

That way the tubes can be broken down for transport and threaded inserts used for the attachment points.
Does that seem doable if I came up with the drawings?
Thanks,
Rod.
