Tandem with with a frame issue
A neighbor gave me an old single speed tandem. It is in rough shape and the head badge is missing. Probably a Columbia or something of that sort. One piece cranks, 26" wheels, one speed, rim brake front and coaster brake in the back.
As I was checking it over I noticed a loose headset (no big deal) and as I worked my way back I saw that the back handlebars are crushed in on one side and the down tube that the rear handlebars are in is loose from the frame. The frame design is split, mixte style in the back, and the tube runs between it.
Would this type of repair be expensive (I will try to upload pictures) and what method can I use to check out the condition of the rest of the frame.
If the frame is not a total loss I want to build up new wheels, clean and repack everything else, replace the seats and posts with something lighter and ride it for a season. If my wife and I like riding a tandem start looking for a nicer lighter one.
Any help or advice will be appreciated.
