I guess the 'scientific experiment' is dead. I sent a 'fellow Pelican' a 'used' cylinder which he measured the surface finish of. Then he mailed it back to me and I had it 'polished' on the Sunnen machine.
I mailed it back to him ( a loooong time ago). And that's where it ended. I haven't heard back from him.
Maybe it dragged on too long and he lost interest? I'm really frustrated that I spent the time and money, all for nothing at this point.
