Atomic Zombie's Carnage chopper bicycle

Step 4 Weld the frame

Because this new bottom bracket was the non threaded type for a one-piece crank arm, I did not have to worry about orientation (no threads), I just put it in place then welded it solid (Photo 4). Even though the rear of the frame is still hinged, the addition of his new tube makes it as solid as if it were welded at every joint. The length of the added tube and the position of the rear triangle prior to welding will determine the rake and height of the frame. For my frame, I wanted the chain stays (which are now on the top) to run parallel with the backbone of the frame.

You will notice that the rear dropouts are now reversed. They could be cut and re-welded, but I left them, as this added some danger and weirdness to the bike. Better make sure those rear wheel nuts are tight, buddy!
