so that is very very untrue. Yes titanium needs to be welded in an inert gas environment but its not welded in a purged room unless its being welded by robots. TIG welding equipment feeds the inert gas into the weld area. The welder doesn't have to wear a hazmat suit with oxygen supply.

Yes titanium is harder to fabricate, that's about the only bit that's true.

Unlike steel, titanium can be welded repeatedly within the heat affected zone provided the material is shielded from oxygen till its below 420degree C. Steel cannot be welded again in the HAZ. Therefore it's possible to repair a titanium frame. You just need a skilled welder.

The UK has never had a strong titanium industry. A lot of the welding and fabrication work for their Oil and Gas and Aerospace industry is contained within that industry and the motorsports industry.

Titanium frame fabrication isn't a cottage industry and that I think is the crux of the negative view. 

Its the same reason Calculus doesn't weld their own frames nor shape the tubes they specify on your custom frame. The drawing and hydroforming of those tubes is left to the specialist fabricator

yeah

 

I have a mate in the UK that does custom ti frames, after much searching he eventually settled on a builder in Italy to do the fabrication.

Not to be facetious, but I could sit and stare at that beaut all day long and not care to ride another bike ever again.

Robbie that's pretty much how I feel about this bike.  I got it June 3rd, ridden pretty much every other day since and my other bikes all have flat tyres

 

I rode a steel roadie one day when when I sent Kevin (the curve) to the shop for something I couldn't fix

..........At the end of the day, only real option is a custom titanium frame.

I like what the juicy one suggested

 Russia is still the biggest supplier of titanium sheet and tubing in the world. The USA is next biggest.

 

 

If you want a really good history of titanium have a listen the this chat on the history of the real Skunk Works.

 

 

 

PS: finished listening to the podcast. Much BS is spoken therein :(

 

 

Watched a documenatry on the skunkworks (not sure if it is the one above) some time ago and they spoke about how they had to find a way to get the Titanium for the SR71 from Russia.....

 

edit: I think it may well have been this doccie..
