At ours the chairperson of each group (machine shop, metalworking, woodworking, automotive, etc) is given funds from memberships and donations to maintain equipment and purchase consumables. I am not sure what kind of insurance policy they have, but I could find out. Training is offered by volunteers who have expertise in the equipment. The organization functions as a non profit and I don't think anyone there is paid outside of membership reimbursement for teaching a class. Some things like 3d printer filament is paid for by weight once you print your part, but you can bring your own and print for free. Most things are totally covered though. For instance you do not have to provide endmills or other tools for the CNC machines, those come out of the membership fees.
I do know that the local fire marshal has an issue with the CNC plasma cutter, so it is currently off limits to run...
