Flashlight
I learned how to use a mill and a lathe to make a flashlight in 2.670 Mechanical Engineering Tools!
This course was a fun 3-day class that I took during IAP. We were briefed on operating many machines, with the end goal of producing a small flashlight. The head of the flashlight was mostly made on a mill, while the body, on a lathe.
Making the flashlight
Machined the body using a Sharp 1340 lathe, then the head using a TRAK DPM SX2P mill. Battery placed inside, flashlight turns on when twisted!
