I'm learning. Slowly, but I'm learning. A few lessons from the workbench...
1) If it feels wrong, it probably is. I started making a cut today, and it felt pretty awkward. I decided to keep on with it, because I couldn't see a better way to do it: the wood I was trimming splintered, and now I've got a slice on the back of one finger where the wood caught me. The good news is, I was using a handsaw, not a table saw, so it's pretty minor and will heal quickly.
2) Keep your bench clean. This one is hard for me. I'm normally... well, I don't want to say "a slob", because to me that implies dirt. In my space, things are usually clean, but scattered. Nothing gets put away. The fact that I have a very limited space to work means that if I don't put things away as soon as I'm done using them, I run into them later. I just had to stop midway through a cut, because it turned out I didn't have space behind the vise for the sawblade; the plane I was using a few minutes before was in my way.
3) Trust your eye, not your measurements. I spent about 20 minutes this morning jury-rigging a way to keep my plane at a 45 degree angle to smooth a bevel I needed to make. It was still remarkably difficult to get the bevel cut right. For the second, third, and fourth -- I'm beveling the top edges of a box to take a similarly beveled top -- I said "forget it, I'm doing it free-hand." So I marked the edge, took off most of the waste by making short cuts with a dovetail saw and knocking them out with a chisel, then used a #3 plane to smooth and finish it. Elapsed time, less than 10 minutes for the longest one. (I judge time by songs; the longest one to do took me all of "Drinking Duncan" and part of "Slip Slidin' Away", both by Paul Simon. So maybe 7-8 minutes.) Each of those three came out cleaner and faster than the one with the jig.
