I was a dyno machinist and assembler at Powertest Inc. in Sussex, WI for 5 years from 2011 to 2016. I had a chance to machine and build nearly everything we made while I was there. I attended the Perfomance Racing Industry show in 2014 as an exhibitor for Stuska Dyno to help sell our product, which was an awesome experience.
We manufactured engine, chassis, and transmission/hydraulic test systems from scratch. I learned alot there, but the ownership and management genuinely looked down on us shop floor pee-ons. I found something better, and moved on to greener pastures(twice as green at this point). Its cool to see stuff in the wild I may have worked on from time to time.
