Hello Cabe'rs. While at a very cool garage sale yesterday that had many tank bikes, cruisers, and hot rod parts I spotted and brought home a Hawthorne duralium frameset. In my enthusiasm I didn't quite look the frame over as closely as I should have and only noticed the broken rear drop when I got home. Bummer but I hope to fix and make it a functional bike once again. Has anybody had repair work done on these frames, are they weldable? I assume they are 6000 series alloy? I have a friend that is a very competent welder and before I contact him about repair I thought i'd ask the pros for guidance first. I sure hope to proceed on this build. Thanks!
