Tool rental or loaning program for members

I could see it going bad because, well, some people see opportunity and just can't resist taking from others.

And let me clarify, I'm not trying to piss in this guy's Corn Flakes. I know what I have in my tools and it's a lot. A whole lot. Local friends that want to come over and borrow my whole shop and tools too? I got no problem with that. I'll even help. For free. Same with online friends. I have to draw the line "somewhere" as they say.
