Looking good dude! bet you can't wait to build it up. Out of curiosity how come you have gone with such thick wall tubing? Is it just mild steel rather than chromoly? Weld wise I'd say it looks like you're running a little hot, that or your gas flow isn't right. What settings were you running? Also what size filler rod you using?
yeah I have a gusset for the front of mine as i was slightly concerned about that but my tubing is twice as thick as usual, top tube is 1.2mm thick, downtube is 1.5mm thick and seatube is 1.7mm thick and stays are 1mm thick
