OK. I got a few hours yesterday to work on the mill. First job was to put the parts back that I had disassembled in order to remove the selector shaft, which I toll with me to the US so that Ken and I could fix it. Ken actually has the pictures of the repair job, which I will have to get from him, so I can post them here.
Putting it back together taught me a very important lesson: Don't remove the quill, without first removing the two screws that locate the quill skirt. The result is torn off tabs
The good thing about this lesson is that I actually had two made up, as there was a minimum job cost when I had them made.
Once the head was back to where I had it previously, I decided to install the quill micrometer screw and the various parts that trigger the trip. This is where I ran into some issues. First, it became evident that the hole for the reverse trip ball lever cover screw had been drilled/threaded crooked, so that the screw had to be modified to stop it locking up the whole assembly. The nipple at the end of the screw had to be turned off.
With this fixed, I turned my attention to the bottom lever, which looked like it had been flame cut and dropped into a bag and shipped as is! The hole in it needed enlarging, as the hole in the head, through which the pivot it installed is drilled on an angle. A lot of filing, sanding and colourful language got it to fit.
I had to leave it there and there is a lot of work to do to get this section sorted out and working. One thing I did note, it that Kondia have changed the design of their reverse ball trip lever. The original one (as you may recall) had a small hole, with no threads, making its removal difficult. The new one has a larger, threaded hole, the same as the Bridgeport ones. Here you can see the new one on the left and the original (bent) one on the right:
