This is quite interesting if you haven't seen tubes being made. The video will play by clicking on the link if you have broadband, for modems you might have to save it to the hard drive then play it. Click on the real player links.
When I need some tube work done I am going to call Nick at Sealion first ! he is on this Forum under the name of Nick
I think Henshaws make the tubes for the proper Ribtecs and the ribeyes are made from the SA tubes. Ribtec are based in the Marina I use and I see a Henshaws transit there quite often. If I needed to retube my Camel then I certainly wouldn't want my tubes to be made by the people that make Ribeyes tubes
The third point of the two which I wish to make is that I have found Ribtec to be rather greedy when it comes to performing work on their boats
