Time to finish the head. :+1: Just the thread for the bezel was missing and space for the reflector needed to be created.
So I just turned the material down to the right diameter and created the space for the thread:
Unfortunately, my indexable threading tool did not fit:
So I adjusted and old HSS tool:
It fitted:
After adjusting the belts for a thread with 0.75 millimetres thread pitch:
I sharpened the HSS steel and started on the threads:
After having been done with the threads it was time to part off the head:
Usually, if there isn’t a hole in the middle I don’t part the workpiece completely off but saw the rest:
Next the head had to go back on the lathe so I could create the space for the reflector. First I checked if the head was sufficiently centred in the chuck:
0.03 millimetres are within tolerance but not more. Since I didn’t have time to grind out my chuck yet (so many things I want to do…) it sometimes takes some time to get the part centred.
Again, just drilled a hole:
and widened it with the boring tool:
After adding chamfers and taking off some of the threads off I was done with the head:
So, nearly done, just the bezel missing :
That’s it for today, thanks for reading and following me so far Enough with flashlights for now, I have to repair something else:
Can anyone guess what that’s for?
