self larnin' goin' on--narrowing rear axle

And... when you go to weld the ends, spot them at four places, and weld as you would on sheetmetal, dont try to run a contenuous bead at one time!! alternate as you go!! After you are done, the bar should slide out pretty easy. If the housing warps slightly, you can heat and quench the tube to straighten it, to a small degree... Taking your time, really pays off here!!
