Hoofddorp Barn, BSA folding Bicycle

[Alex van de Wetering]

Attached you will find some pictures of the repair work on the seat-frametube. The former owner forced a new seat post into the frame. Nothing wrong so far.....but remains of the original BSA seat post were still in the tube....in the end the frame tube was forced to expend which resulted in a crack.
I wasn't satisfied with the frame crack, especially when my intention was to actually drive the bike.
It was extremely difficult to get the seat post out, in order to repair the frame tube. In the end I even had to open the crack a little further, before the seat post could be removed. I than started cleaning up the tube, bending it in the right shape again, welding it and sanding down the welds with a powerfile.
I wasn't able to get all the remains of the original BSA seat post out of the frame, so I decided to leave it and make a "custom" seat post with a slightly smaller diameter at the bottom.
