Buzz,
Not enough to destroy a part, or, the vise. That, is bad form.
The vocational program at Coon Rapids High School, and, the Junior High were outstanding. By my junior year in high school, I had 4 years of metal shop, 4 years of wood shop, the small gas engines course, 3 years of electrical, a year of drafting, and had just wrapped up auto one, and would complete auto two before summer vacation. Completing auto two meant you had rebuilt a school V8 engine and both a three speed manual and automatic transmission. I was a teachers assistant in the auto shop my senior year. I made my living as a machinist and machine maintenance mechanic until I transitioned into lithography, where I also spent a bunch of years rebuilding equipment, mostly in shops that were down from their hay day.
My shop courses have been the most valuable schooling I received in my entire life.
The teachers saw to it that the tools were well cared for. Ive broken a few drill bits and taps that I recall. Never broken a vise.
Best,
Ted
