Thanks again...
My machining work is adequate for the task and certtainly looks the part in this case. I am not a professional machinist. The 20" CF truss Ritchey-Chretien build ATM thread by Preston on Cloudy Nights is an example of the 'excellent' end of the serious ATM spectrum - worth a look and inspirational if not daunting. I'm sure there are more skilled astro-oriented machinists like Preston still lurking on this forum and elsewhere.
I am considering doing very small runs of these VC truss conversions for people - or am happy to advise people. This was never my intention when I started the project however - just a curiosity project for me - more a response to personal feedback off forum. There is about a week of milling & drilling required for the two prototypes so turnaround would not be immediate if this went anywhere.
