The parts have come off a tractor that's been sat outside unused for a long time, maybe 20-30 years. Somebody else took the rust and crud off.
One of these needs some work:
Between centres on the lathe. I had to do very light cuts, 0.1mm, as there wasn't much friction driving it.
Turned to diameter:
I need to modify a die holder and cut a split die into two parts so as to be able to recut the thread from the good end. The other option is screwcutting in the lathe but that involves much faffing with gears and feed speeds.
Next is the steering column. On the lathe to clean the bit a new collar will fit over.
The collar, made of brass, will fit in here and will help take the play out of the steering system.
Creating the hole.
Fitted, with one mistake. I forgot to allow for the chamfer so that's as far in as it goes. The protruding part won't foul anything.
That's the die slit :
And assembled onto the thread.
First pass:
It came out rather well. I ran the die up and down a few times, tightening it slightly each time.
