I've been a tinkerer/builder all my 63 years. From working on cars (when you had to fiddle with ignition points and valve lash) to woodworking to computers, if it is mechanical I love it. Even when working for IBM my favorites were the older machines with lots of moving parts.
One of my favorite phrases is "I've done so much, with so little, for so long, I am now qualified to anything with nothing."
Anyhow... I'm glad I found this community of like-minded tinkerers and fettlers.
