Hi. I am new to the bike building hobby so please excuse my stupid questions. I am building a LWB recumbent that is a cross between the Meridian and the Original Marauder (chain stays are horizontal resulting in a seat height between the two bikes). I have recently bought some 1.5" x 1.5" x .083" 1026 tubing. All the posts that I can find call for 3/32" (.093") wall thickness. Will the thinner wall cause me any problems? Also is any specific AISI grade best for frame building? Thanks for any help.
