[ATM] next mirror.....

["Jan van gastel" <jhm.vangastel@wanadoo.nl>]

I am making my first mirror (300 mm f/5) and ready to start with 600 grit.
Think I finish finegrinding on friday (and after that I'll have to do the
polishing and figuring of course).

I am already thinking of a next, larger mirror, but I wonder if it is
possible to grind a large (larger then 20 inch) without a grinding machine,
because of the weight. It's easy to take a 5 kilo mirror from the tool
bewteen wets, but a 25 kilo or heavier mirror will be more difficult. Can it
be done without being a professional weightlifter?
