Steel/aluminum steel strength, bicycle building and other questions
I dabble in metalworking for fun. I also run marathons and some triathlons. Been thinking it would be neat to be able to say I built a bike and used it in the triathlon. I have a road bike but not a triathlon bike.
As far as frame, I am limited becasue I dont have a tig welder. I do however have a mig, oxy torch/weld set and arc welder. I am guessing my choices are aluminum tubing or chrome moly steel. I can mig weld the tubing with argon and aluminum wire but not sure if this is ideal. I have read you can braze it. I have read conflicting advice as to whehter it is recommended to mig 4130 or not. (The same for brazing it). Weight is an issue. I want it to be light but at the same time be strong enough to do a half or full ironman. 56 miles/112 miles. I appreciate it! |
