Damn...
I don't even want to think about what that much titanium tubing set him back, let alone the welding & forming setup.
Some people have way too much money... and I should be one of them. [/bitter]

Somewhere in that thread he mentions a little bit of the costs involved. Seems like a lot of work for 12 lbs of weight savings, but like most DIY guys, I'm guessing that wasn't really the point. :dthumb:

nice...

met a guy this past spring at a group meet that use to own a ducati race team. Couple of his riders have been to the meets in the past. He was an older guy, cool as hell. Rode to the meet in the rain on Monster. He owns 1 of 3 full ti Monsters.

Its his baby :dribble:

FUCK THAT!

No way I'm riding on a frame made anywhere other than an approved mass production factory.

Right, Ed? ;)

the frame needs more air/speed holes for ram air

I just want to know how he was able to make that entire thing without it discoloring at all

That's pretty fucking hot. Needs to do something about that tail light and I've seen trick billet timing belt covers that would looke fucking money on that...

i;ve been thinking about the belt covers myself, i i like open covers dunno if a person actually rides teh bike if you want open covers, exposed to the elements and rocks and such vs a "show" bike no biggie.

I don't think I'd be too worried about rocks and shit...

a belt is like $200, let alone the labor.

hmmmm

somebody here locally has clear center covers, thats may be the way to go IMO

Unless you live somewhere really gravelly, I'd say the chances of one ending up in that belt are pretty damn slim...

Been a while since I welded anything (and never titanium). But Titanium requires a shielding gas. Titanium reacts with oxygen like crazy. So much so that when in liquid form (pretty much what your weld will be) it can actually remove oxygen from hydrogen in water (which is all around us). That creates hydrogen gas which is not good because hydrogen is sluttier than a fat chick at last call and will react with anything.

I think you are suppose to use helium for Ti which is also super expensive becuase it requires a lot (He is much lighter than air). Because you use a non-reactive noble gas you won't get the discoloration taht oxygen causes.

Why wouldn't you use argon?

Yep, that's what the guy in this thread did. He mentioned it a few pages into the linked thread.

Argon would work. I just thought I remember some Ti welders I knew mentioning they like to use helium for Ti. Helium is not reactive at all while Argon can be slightly more reactive due to a larger electron cloud. As in it is easier for other elements to pull away an electron from Argon which has a larger electron cloud (where electrons are farther away from the nucleus) than it is from helium which has a much smaller one.

But from a macro level such as welding a Ti frame I doubt it matters much.
