Ok, so I'm tired of hand grinding! Mel Bartles sent me some picts of his
machine and I have read Alan Macintosh's articles on grinding machines.
Along with other material I have read I conclude the following:
1) Table speed around 100 rpm (seems high to me)
2) Stroke speed is around 30-40 (seems reasonable)
Do those values sound correct or what should they be? Spring is here in
California and it is time to get outside ad _DO_ things, like make a
grinding machine.
I'm still not sure if machines can produce the classic W stroke.
If they do, how is it acomplished? I'm getting ready to lay this puppie
out and make it.
Last comment not pertenent to this subject, but it is interesting if
someone is making reflectors from aluminum and anodizing the surface, if
that is the case. It is easy to confuse al coatings on glass with anodizing
61" al mirrors. Wow it is mind boogleing,
Bob
