I have access to 8 CNC machines at the shop. Whenever they aren't busy with a current job, I'm allowed to do anything with them after shift. I'm Lead Tooling designer here, and program the machines to cut the tooling also. I also have Bridgeports and lathes at my disposal. I've made some really cool one offs for the Harleys I've had in the past.
My "Job" is only that in the sense that I get paid to do it. I usually find it interesting and fun..... meaning I don't really feel like I work for a living... they pay me to play.
