Since the body had the right diameter I could prepare cutting the threads for the tailcap:
With a parting tool I made the indents for the O-rings:
Using an indexable threading tool I cut the threads on the body:
You get nice little shavings:
After the threading was done I added chamfers to every sharp edge:
Even to the one I can’t reach with the normal tool:
Having done that it’s time for a test fitting:
It fits very nicely and here it also pays off that I have been that precise - you can’t see the transition between tailcap and body:
I parted off the tailcap with a little excess material (it is easier to take material away than to add to it), so I measured the length of the tailcap and need to take 0.05 mm of material away:
Now it’s time to finish off the tailcap and adding some chamfers:
The tailcap is done:
I continued by shaping the body:
Since I changed the angle of the cross slide several times I needed to measure again:
And the body is shaped on the outside:
Looks already very flashlight like:
That’s it for now, thanks for reading and more later.
