Committees can come up with whatever restrictions / rules on tools in their area. All the people offering lift training are approved by me and follow a standard curriculum. There hasn’t been a large backlog for lift classes so the more ad hoc scheduling approach has seemed to work well.
Primarily I went with a one time fee for the lift to generate revenue for the auto committee (any other kind of usage rate like hourly fee would not be practical or safe). For example just tonight I delivered $173 worth of supplies paid for by lift fees. Better glass cleaner, box of 144 microfiber cloths, safer strut compressor, that all DMS members are free to use. (Not to mention the ~600 I spent last week on completing our impact socket set and other tools.)
Insurance is a complex topic, it gets paid out of our general funds, so the entire DMS membership is paying more to allow automotive to exist. Several board members put in a lot of hours of work to keep automotive at DMS, we came very close last year to having to forbid any kind of automotive / mechanical work at all. Most of the we can’t do any classes talk is from before the insurance change up last year that allowed auto to continue. I haven’t looked into the exact working of the new insurance rules because I have been content with not encouraging people who wouldn’t otherwise work on their cars to do so and not pushing any boundaries on what we are allowed to do.
