I can't quite figger how to fab these girder fork tubes...
How were they made?
any suggestions?

...for a 26" cruiser bicycle scale...

I was thinking, perhaps, of using muffler tubing and crushing it to oval in a press, then making a V cut, a short one at the top, and musch longer one at the bottom, closing up the V, then welding up... then all the other brackets and stuff...

kind of a lotta work!

But i really like th look of the chief girders! lol

That's beautiful, Gnu, but I really like the Chief single tube girder look, and want to learn how it's made.
...or How I can make one like it for motorized bicycle service...

nah, couldn't do that... I've seen where guys flame cut some rather long girders from flat stock on REAL motorcycles, and that's not something I want to do.

I probably should get the fittings so I can get my plasma cutter functioning properly, though.
I've only used it to test the function.. and made a real mess, but the machine worked as it should!

Tnx
