On the back of this morning’s discussions I had another go and used the Slitting saw to separate them. With much more precise results.

This is the basic shape milled from another plug

Then cut with a 0.5mm slitting saw. My first go with the slitting saw that I got for my birthday a couple of months ago. Very nerve wracking!!!

After a brief clean up with a diamond file.

Finally cut off from the main pin. as long as I don’t lose any I have one spare at the minute.
