I learned to set-up and operate a Bridgeport mill, Atlas lathe, Harig Surface grinder and fairly proficient with a stick welder at 10 - 11 years old. So I started out as a machinist and finally a Mold Maker. I'm retired now. My vote has to go to;This Old Tony. His content is spot on and over the years his humor has gotten entertaining. My favorite video about gears, is in depth and something he should be very proud of. I have built tooling for helical gears. It was done with a sinker EDM and the electrode actually rotates as it erodes the steel. I did gear research for about a week to make certain that the cavity would have the correct dimensions due to (plastic) shrink factor and releasing the part from the mold. I've been intrigued by gears ever since.
