A few years back I started riding a bike to commute to and from work.  I like to drink large cokes and iced teas so I felt the need for a cupholder that would fit my 64oz cup.  None of the sport bottle holders I saw were even close, so I made a heavy duty cupholder for my bike out of a chunk of aluminum driveline. I used a discarded aluminum driveline from the scrap metal bin at work that was the correct diameter.

I started by disassembling the driveline, then I cut the piece for my cupholder from the driveline by cutting the tube 6 inches above the yoke end weld and cutting off the majority of the yoke below the weld.  I ground down the yoke side to roughly 1/4 inch from the weld, sanded the weld smooth, drew a design pattern, and drilled many holes in the tube according to the design to make the cupholder lighter and more ornate.  After drilling holes for the mounting bolts I bolted it to the bike frame.
