Fixing a Victorian

Common commuter bikes in 1920/30s were roadster (bolt up rear stays) 24 inch frame 12 inch bottom bracket. rod brakes 28 x 1 1/2 wheels 7 inch cranks and around 67 degree angles. , many with hub gear. generally black to make them look strong (illusion).
These usually had the saddle at its lowest and were still too large..
By the late 30s the need to stop with a foot on the ground in traffic resulted in an overdue revision. So 26 inch wheels bracket height 10.5 inches fully brazed frames , 70 or71 degree angles. and frame 21 or 23 inch.

More problems. On today’s test beat the handle bars came loose. I was cornering and put too much force on the bars and the bolt that pinches the gooseneck tight to the bars pulled right out of the gooseneck. All the threads stripped inside the gooseneck and I bent the gooseneck a little. This is a dead end threaded hole that stripped. The threading was shallow and already messed up from years of use. Before I just weld the bars to the gooseneck I’m going to see if I can drill and tap the hole for an oversized grade 8 bolt. This thing is driving me more crazy than average.

Seems like every little thing expands in a multitude of little projects and bodges. Interesting for us, less so for you. Hope you'll have it rideable soon enough mate. Great undertaking this, though, and very compelling to follow.

Bugger. It's also pretty scary when that happens - had a similar thing happen when one of the two bolts in the face plate decided to pull some aluminium threads away. Riding back in the saddle one hand on the bars and the other on the stem for 20 km was not fun.

Sounds like the entire front end could do with a re-think - failed bar & stem plus a cramped position would have me trying something else.

Well, that is what anyone else would do. This thing is dangerous to ride. The pedals dig into your soles and the lip at the end of the quill make it difficult to quickly remove your foot. Riding position was probably considered aggressive back then, now just dumb. I want to get it so it’s reliable to ride a few miles 2-3 times a year.
