today was quite productive, the apron parts were cleaned up and it was reassembled, then it was the turn of the headstock to be cleaned up.
This is the gear that the handwheel drives, it still functions although there is a fair amount of damage to the teeth, to be honest I cant think how that might have happened.
The two half nuts, now I dont know how much engagement there should be , but these look a bit worn - well I suppose it could have been well used in 100 years.
The rerassembled Apron, nicely cleaned up and greased on reassembly.
the backgear driven gear on the left end of the spindle is not in the best of shape, it does however work smoothly.
the gear on the end of the spindle is worse if that was possible, yet after cleaning the dirt out of the spaces between the teeth, it still meshes and runs smoothly to my amazement.
the reassembled headstock.
I also reassembled the reverse gear, all except the nut, this was the thread that i managed to split in half down the centre, and then flatten out with the copper hammer, this thread will need to be reformed or the part remade.
I do have an option, and that is to repair it the same as the lead screw end thread has been repaired, at some point in its history the threaded section of the lead screw was broken, as someone has drilled in from the end, and tapped the new thread in for a length and pinned it in place, I think this may be a route I may investigate for replacing this thread. either by making a stepped stud with a smaller thread to fit into the part, or possible I may just end up drilling and tapping for a cap screw and washer, i have yet to decide the solution.
