OK GUYS I STILL HAVE NOT GOT A MOTOR FO MY BIKE YET. BUT THERE WAS A POST ON THE DIF WELDERS FOLKS USE AND I THOUGHT I WOULD SHARE WHAT I KNOW ABOUT THIS. ME AND A FREIND OF MINE WAS IN THE SHOP THIS WEEKEND AND WE MADE A VIDEO USING A HARBOR FREIGHT WELDER. THIS MACHINE IS CHEAP AND WORKS. MAY HELP SOME OF YOU FOLKS THAT FAB YOUR OWN STUFF.
