making my jers t-bars

here's my new design t-bars, my goal is the make really strong single tubing t-bars, already tested it and make several r&d's, also smash it really hard (yung risers ang nasira pero walang problema sa t-bar.) 

a larger diameter thick guage tube was slip on top of 7/8inch thick guage tubing. 

first tig welded the inner, then the outer larger tube.

if not stronger i guess it will be same strenght with standard t-bars.

for peace of mind i drilled several holes for back welding.

here's the pic of back weld.

cleaned.
