Thank you Kevin. I hope I didn't sound dismissive, they look like a good company.
Haha! Good old A.I. Seems to be everywhere, no surprise that it pointed the way to JRA! I have to say, I'm in a few forums, old VWs, 3D printing etc. and nowhere have I found so many very knowledgable and very helpful people.
I'm sort of coming to the decision that making an 8 stave, birds mouth wooden mast might be my best option, if I can source some good timber.
I'm sure there must be some people here who have done it, do you know of any?
