Nadine and Florian bought an old springer fork and had also found a nice little 2-leading shoe drumbrake and asked me to help matching these together. Sure! Upon inspecting the springer I found that there were some nissing parts and some that were quite worn out. I also found that the forks were British and all the nuts and bolts were Whitworth Fine (BSF) threads, which are very difficult to find nowadays...
 
 
The 4 rocker bolts were all there, but the hexagonal holes were very damaged and I did not want to give them back like that. Replacement bolts were impossible to find so I took them to my friends at Heemskerk Metaalbewerking and they put in new oversized hex holes.
 
 
Next on the list, all 4 pivots were completely worn out, and even the holes in the rockers were worn both tapered and oval. I machined all 4 holes to exactly 20 mm and made new oversized bushings with undersized holes from bronze. These I pressed intio the rockers with a bit of Loctite to make extra sure they would stay there.
 
 
As the 4 pivot bolts all had slightly different diameters, I used adjustable reamers to make each bushing fit the matching bolt perfectly
