An old machinist at home when I was a kid had a monopoly on drilling spring leaves for overload springs on heavy trucks and trailers. To add leaves to support a bigger load they had to drill the new leaves to accept the center bolt that held the spring together. The old boy was the only one for miles around that could drill a spring leaf and wouldn't let anybody watch him do it...... not even his sons that worked with him in the shop. They found an envelope in the safe after he died....... he drilled down through small blocks of dry ice to keep the bit cool so it wouldn't lose it's temper and stop cutting. The dry ice he used came from the incinerator bin behind the drugstore......... it came in with the 2 1/2 gal tubs of ice cream they used to make your choclate frappe' ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ "Education is when you read the fine print.
