^^^ I have one of these, but find it's utility to be quite limited. Generally it's too large for most things in my experience. Maybe if you work on lots of large pocket watches it would come in handy, but not so much for wrist watch sized items.
Yeah, I found the included pins are too large. They make smaller ones, which I now have to order. Otherwise I will have to grind my own pins to size.
I considered the alum method, but there are other iron parts near by.
Watchmaking is about patience and waiting.
