Sounds like a good idea to me. I used the auto craft shops on lots of different posts, and it was great having all that stuff available.
I think the key is doing what those places do: they make you take a test before you can ever use the place, and the user signs a waiver. The test covered use of certain pieces of equipment, safety, and rules of the facility, if I remember correctly. The waiver protected the shop from liability.
But that was on a military base, where everyone has free health care and liability is less of a concern.
