Brian, it worked once to perfection but I'm not naive enough to think bad things couldn't happen. Just one oversize grain of sand that made it through the sieve or even setting a strain up by not cutting a consistent depth on each pass could make alot of little pieces happen. We need to get a couple tempered glasses and whittle several 2 or 3 inch strips off them before we can say it works every (or at least most) the time. The merc belonged to a friend and he had an extra glass so we said, "what the heck".
