Things you shouldn't do. Especially twice
If you see someone misusing tools, appliances or small children apparently unaware of how stupid they're being, please tell them. And write it up here, at the top where it will be read, in the hope that someone else will learn, too. No need for names (unless, of course, you want to).
Wood drills
There are various sorts of drill bits made especially for wood, because it's soft and easy to cut. If they're used for metal, they'll go blunt very quickly indeed. Wood drills can be flat, in a spade shape. Or they can be a big coarse spiral with a tiny woodscrew thing at the tip. Or they can be cylindrical and short, also with a central pip or screw. Metal drills are simple spirals, and can also be used for wood.
Bandsaw
There are various sorts of saw blades for the bandsaw intended for wood or metal. Using the wrong kind of blade will, if you're lucky, just break the bandsaw. If not then, well, all kinds of bad things can happen when a fast rotating sharp edged band of metal snaps under stress. A simple rule is to check the blade against the kind of straight saw you'd use on your chosen material. If it looks like a hacksaw blade, it's for metal. If it looks like a woodsaw blade, it's for wood. Changing the blade on the bandsaw is possible, but should only be done by someone who has the training.
Laser cooler
Don't run the laser with the lid off the cooler and a fan blowing on it. Sure, it will increase the cooling rate. It will also blow dust & muck into the system and it's supposed to be distilled water. BTW, the dead bee was probably there already.
Servers
Servers in the space (which include Doorbot, Babbage and the router) are shared. Do not restart them because you want to do a dist-upgrade or because it's running at high load. A large number of people use Babbage as an IRC bouncer and for playing with code, so you'll be killing their sessions. Doorbot and the router are sensitive and important to every member, so you should have a very good reason to touch them.
