Re: Best frame building material

for teams looking to easy construction you can also use steel tubing...now before you react to say that i am crazy think about this.

a piece of carbon tube steel (1/8 wall) .5" x .5" x 36" weights 1.5 lbs

a piece of 6061 alum tube (1/8 wall) 1" x1 " x 36 " weights 1.4 lbs

the weight difference between alum and steel is not very much when the steel is half the size

for teams who want an easy material to work with without having to buy all the attachment components with extrusion, think steel. much easier to weld, much less expensive, locally available everywhere, easy to machine


you might want to consider this when looking at materials for the upcoming season
