It was several years back, but when I needed a lathe to fix a lathe I checked out the local "Maker's Space".
Their lathe was out of order (maybe permanently) because someone had decided to "fix" it. There was ZERO training offered to anyone on any machine, likely because there was no one competent to do it. I certainly wasn't informed about any insurance. I considered offering to do some instructing and basic saftey training, but all they were really interested in was me paying a monthly fee until the end of time for the privileged of being able to walk through the door, certainly not in taking advantage of the fact that unlike everyone else there I had greater than zero experience. It felt like a bunch of 5 year olds, and the blind leading the blind.
I hope Maker's Spaces in other places and times are better, but I quickly walked away from that one and never looked in that direction again.
