I was eager to start on the reassembly today after a week of being stuck in the house recovering from a serious respiratory virus.
Beginning with the fork, I grabbed the crown race which at over 80 years old was badly worn. I had used this crown race with the fork before and found the fork was binding up. All the CWC forks I have, use a crown race (CR) with an ID of 25.4 rather than the more common size of 26.4. It is impossible to find new a new headset with a 25.4 CR, so I bought a new Tange MX125 sealed head set with the intention of using it with the CWC crown race. As this head set has sealed bearings it doesn’t matter if the CR is worn as it mates to a machined surface rather than ball bearings.
I began by lubing the head tube and cups with anti seize paste and then pressed them in with my trusty Park tool. Finally I fitted the fork. Problem 1 was solved and the fork now turned smoothly.
Next I got to work on the BB. The BB on the frame was stretched so the cups had to be shimmed. I cut some thin strips out of a can of Guinness (yes I drank it as I worked on the frame) and applied a little Loctite 680 adhesive to them before pressing them in with my Park tool. The adhesive needs to set overnight so I decided to leave the tool fitted to hold them in.
I am hoping tomorrow after I am
done at work, I can get the cranks, stem and bars fitted.
