Also made a pulley. This was neat, as we did everything from start to finish. Made a sand mold to cast the blanks, and then turned it on a lathe. Broached a keyway through the center hole, also drilled and tapped a hole for a set screw. I had fun with this one until I broke the carbide cutting tool on the lathe... :-X

Well, this wasn't a CNC lathe, it was manual, with power feed, etc... I had the pulley butted up against the chuck, and was turning the outside diameter with a slow feed rate (finishing pass) and I let the tool go just a hair too far, and it hit the chuck, and the chuck broke the carbide tip right off... :-[ I was so embarrassed, lol. Luckily, the instructors were cool about it, and just gave me another tip. :D
