Thank you, Lin.
Do you spin pins?

What exactly is the head spinner is supposed to do to the pin material? Is it to just cut the end of the pin into a rounded end, or is it to mushroom the material over to make a head that is larger than the diameter of the pin?
I've never tried a carbide spinner. Maybe the carbide is superior.

After reading down through the rest of today's posts, it sounds like coming on a good spinner isn't easy. Sometime/somewhere in the past I got the idea spinning pins actually flared them a little, not just rounded them off.

Lin, that video was very helpful...now I understand. I'll have to give it a go sometime
Ed, I had forgotten I had an interest in it until I read the domed pin thread again.
One thing that is maybe related... where Steve Culver got rings and gouges even after modifying the tool. I watched a custom rifle builder put a finish on some metal with a wire wheel (0.005" wires) and 3-in-One oil over 400-grit (U.S. grit numbers, not European). He never let it go dry and he said letting it go dry would cause galling. The finish was a very light gray, high luster. Causes me to wonder if oil, or maybe wax, on the pin and spinner would change the outcome?
