A fairly frequent damage in bikes from the 1920s is the breakage of the fork tube. Repair that is also necessary when the thread is worn and no longer allows the assembly of the headset.
In this case the break occurred at the base of the pipe, near the fork head.
The first intervention, once the damaged tube had been eliminated, was to turn a steel tube to be inserted into a new tube taken from an old “donor” fork so as to make the repaired fork more resistant.
Holes were made in the tube of the donor fork to facilitate the entry and propagation of the brazing alloy, the Castolin, and the two pieces were assembled integrally.
Finally, after careful positioning to square the tube with the fork head, we proceeded with welding.
This is the final result.
