Another hobby I would love to participate in... woodworking.
In college I majored in Product Design, and we had to build prototypes of the stuff we designed, so to that end we had a fully-equipped woodworking shop on campus. I spent a lot of time in that shop, not only building full-scale prototypes of things I had designed for class, but stuff I built just for myself. I loved the smell of sawdust!
Case in point... like I posted previously, I was huge into super high-end audio gear back then. I read "Stereo Review" religiously. I bought the best of the best... amps, pre-amps, tuners, turntables, cartridges, etc. Spent a fortune on that stuff.
Sooo... after I had assembled my "dream team" of audio components, I needed a way to put everything together. So I built my own custom audio tower/rack. On top, the amp, preamp, and tuner... in the middle the turntable, and below that, record storage behind black plex doors. The case was walnut, the whole thing stands about six feet tall. When I finished building it, I realized I had no way to get the darn thing home! Luckily, the guy who was in charge of the shop offered to lend me his truck so that I could bring that monster home.
Yes, I still have that system.
And that's when I fell in love with woodworking. But to equip a functional woodworking shop with all the needed tools would cost a fortune. Never mind the fact that I have no space to create a woodworking shop. So I can only remember the "good old days" when I had access to a well-equipped woodworking shop. Sure wish I could do that now, but there's no way.
