Hello all,
I'm brand new to this forum and to frame building, so go easy on me.
Also, let me know if I'm posting this in the wrong place.
As stated in the title, I am hoping to build up a titanium framed dirt jumping bike. I am looking for any and all criticism and advice on this idea. I will also list below a number of questions that I will absolutely love to have you guys answer. Thanks.
I work at an aircraft tube bending facility and have access to quite a bit of scrap titanium. It will cost me nothing to acquire the main tubes, but I plan on Buying the BB, steer tube and other necessities from Paragon Machining. I don't know how to weld Titanium, but the welder at my shop agreed to do it for me. All and all, the frame shouldn't cost too much $ out of pocket.
Also, just for more information, I weigh about 130 and can make fairly smooth landings off jumps.
1 I can get free 3/2.5 class 1 type 1 CWSR 105 titanium tubing from my work. It is not butted. Is that an acceptable material? I know grade 9 ti is best, but will other grades work too?
2 What wall thickness is best for the respective frame tubes? The main one's at my work are .022" .025" .035" .044". I assume the thicker is the better, but at the same time I am trying to make this as light as possible.
3 What are the best ODs for the respective frame tubes?
Sorry for being such a newbie,
Thank you
