Best ways to get free access to a metal shop
So im looking for ways that people are able to get access to metal working tools for quick projects for free. All I need to do is just turn a flashlight body on a lathe and make the inside of the body 18.5mm (from 16.5mm) so that i can fit 18650 size batteries. I was thinking maby I could call up a metal shop and ask to machine the body if I help clean up the shop at the end of the day or see if I could find someone in my area with a lathe.
If anyone has any ideas or proven ways to get quick metal projects done please post away.
