Who would have thought I would be using my lathe to modify my wife's purse? She had a little black purse that had no place to connect a strap so I thought I would give it a try. Here is what I came up with (several hours later). These are try number 2.
I used a South Bend 10K with a milling attachment to get the job done. As usual, I learned several things I would not have learned without actually making something.
First, I learned how to make a uniform curved end. On my first attempt I tried to grind the arc in but that was a bust. Then I tried using a forming tool to round off the brass stock before I milled the flat spots. That worked like a charm although the process was a bit counterintuitive.
Secondly I learned that a regular tap needs a bit more length of material than it will make threads in because it has a good bit of starter area ground on to it that produces no useful threads. Eventually, I ground the end of a tap flat to try to get more good threads in a small bit of stock. I was a bit late though so I decided to just drill my hole clear through into the clipping hole as you can see.
And Bob is your uncle.
