"George Sohnle"

Anybody have any ideas on how to make a "rounded" edge on a 1/4 inch rod?
I am making some screws, and need to have the end rounded.

I assume you want to get rid of that horrible sharp, tapering splinter of
metal left after the thread finishes at the beginning of a thread*. I use a
very small ( jewelers ) file with a safe edge and just file it down to the
root diameter through about one third the circumference. By the way, those
thread 'splinters' are diabolical if you get one inserted into your finger
as the rod rotates and you go cleaning it with paper held in your fingers.
OUCH ! Best to remove it and show what a pro you are.

* I dont know how the thread finishes at the begining of a thread either ! I
guess space really is curved. Now let me have another go at cutting that
Mobius strip in 2 halves just one more time.
