I started last night.
narrow childrens bars are very difficult to find.
since I had at least 6 sets of not valuable drops in the shed I thought I would try something.
the most difficult part is moving the sleeve over on the bar,
this set had a punch dent in the center-this was drilled out.
liberal use of wd40 and th eheatgun and it started to move, I used the stem tightend down on the side of the sleeve so i had something to hammer on.
I soon discovered this is not very effective.
I made some measurements and with the pipe cutter (one with wheel)
I cut off one horn, and then was able to hammer out the other side after carefully bracing the sleeve.
after this everything was easy.
the sleeve I decided needed to be narrowed abit so the joint would be exposed closer to the center line.
I had 410mm and need 340mm
I removed 37mm from one side and the rest from the other side.
after some fitting (sanding and polishing)
I was able to assemble my 340mm bars.
the ID is about 20mm,
I will go to my friend the welder adn find an aluminum pipe that is this OD to fit inside the joint, he will then weld the 2 halves together and I will polish and then epoxy the sleeve in the correct position.
Alan frames are held together with epoxy- I believe this will be a successful and quality job.

If you have a damaged set of bars with a clean center sleeve I would like to have it. hopefully I can build with some cinelli and 3ttt sleeves.
when the first bar is complete I will be happy to do this service for others
