I spent the afternoon dealing with different problems.
I started working on the gears. I successfully connected the hub, but the front derailer was not cooperating.
First of all the frame mounted cable stop looks like it is for a thinner cable. Then the rerouting pulley failed. They are both thin metal and the cable stop is slipping down the seat tube. Some leather underneath might help, but the pull felt very heavy, probably because of the 180 degree turn at the end.
Then I tried to run the cable from the top tube, which was absolutely hideous to the point that I didn't even care if it worked.
Eventually I found out that one of the other derailers has a routing channel so it allows me to run the cable under the BB along with the other cables.
That derailer is visually not such a good fit but whatever.
I was able to bolt this cable stop...
To a derailer that I cut the cage off:
Which I intend to use as a clamp. There is a small clearance issue but I will remove some more material and it should fit just underneath the actual detailer.
I hope it works this time.
