I will take some good pics of mine for ya. I bought some prebent aircraft aluminum tube. You can get from hobby aircraft aviators catalogues for about $40. I used a friends mill to cut new flanges and fit it all together. Tacked it up, and welded it out. I have some pics on here but I do this from my phone and the search thing dont work well for me.
Maybe one of the mods will help out here. Or another guy who is magic with the search thing not a mod but a charter member.

I have no faith in human perfectability. I think that human exertion will have no appreciable effect upon humanity. Man is now only more active - not more happy - nor more wise, than he was 6000 years ago. Edgar Allan Poe
