As someone that spends a lot of time in my workshop, using tools and making things, these words echo in my memory: "Well I had to remove the safety guard to get a better angle..." Maybe my memory is unreliable, but that is how I remember my father explaining how he had caught his thumb with an angle grinder, and later a router.
Having turned one of our rooms into a study for my wife, the box room is mine. You might suggest that it is a little extravagant to have a study each, but my wife's study is a very personal space for her, and whilst she lets me use it to work from home, she does so grudgingly ;-)
The truth is that a study is incomplete until a copious amount of books can be unpacked onto shelves. In our rented house we had a few standalone bookshelves, but what is the point of owning a house if you don't put up wall hung shelves?
A long time ago I built a little pan and tilt mount from some scavenged electronics (a stepper motor from a printer and a worm drive from a cd player) I connected it via a parallel port and used darlington arrays and direct pin out of the parallel port to control the whole thing from some script language, I forget which. It was a little unreliable and fairly cumbersome but it got the job done.
One of the things I wanted to try with my CNC router from the start was cutting metal. I've been building up to it as I learned the limits of my machine and got a sense for what it can do.
