Arggggggggggggh, hate admitting I was wrong...and right lol.
OK OK OK OK, wasnt 3/16 material, only 1/8....I don't know how, must've been a really late night.
But still yet, the way this axle is made, it is stronger than tubing. Have shown it to the engineers, all agree, better than tube.
Flyinb found another one in his pile-o-mower stuff, built close to same, is a strong piece.
The only thing I don't like is the lack of spindle bearings.
Fact is, the tracks we will be running at require "stock axles", so we have no choice.
Thanks for all the help.
