Brass changeplate has no manufacturere marks I can find.
Headstock removed 4 bolts, gap bed. rear leadscrew gears in place crosshatched bed
Headstock siezed, both gear changers pins siezed, the right one came free , the left i had to hacksaw through after three weeks of occasionaly brutal encouragment to leave the hole. I tried punching out from the inside . no. hacksaw, lever came off ok, then drilled the pin out, came away in the end.
First gear came off theh end of the leadscrew ok, with a bit of woodruff key, alarm bell should have started.
Who did this. and didn't tell. . To get the second gear off I had to needle file the offset lip down. Yes I also cracked the cast iron gear holding pick up arm TIG back with nickle . Everything was rust siezed. . days .
the upper ring is threaded on the shaft and holds the Timken bearings together , it needs to be gentely released and the shaft tapped out forward as there is very little slack in the mid stage assembly. Pig of a job, my hope of saving the upper bearing was futile. I did terrible things to many parts befre I understood the mechanism of harmless seperation..
Going through the photos I have now spotted the three grub screws I have left in a tray . they are from the lower wheel set not part of this image. Dohh. It was running rough through the head gears.(direct its smooth and quiet)
So I bought a crappy old machine that turned out to have serious bearings in it.
