I've wanted to build a tandem for quite a long time but never really found the will power to do so... until I met my girlfriend! :D
I asked her "If I build a tandem, would you trust me and my creation enough to ride it with me?". The answer was "YES", so from that moment I was determined to build ourselves a tandem!
I scavenged two old bikes, one with a frame large enough for me and another with a smaller frame for mademoiselle. Oh, if you didn't get it yet, the idea was to cut and weld two bike frames together to make the tandem, and that's pretty much EXACTLY what I did.
Step 1: Cutting and preparing the frames
- FIRST CUT: You need to cut off the rear triangle of the frame that will be used in the front. I did this with a hacking saw and then smoothed everything out using a grinder.
- SECOND CUT: Here, you only need to cut the head tube of the rear frame in half (vertically!) straight down the middle.
