Weird Dreams

The other day I had a strange dream.

I was at a lounge talking with a waitress and we were doodling nonsense on a napkin. My drawings slowly morphed into something that was a lot like a Hilbert curve but not quite.

Our talk drifted into space filling curves and I kept trying to draw it but even tough I knew how it should look I always managed to draw something like a very simplified sandcastle.

Today I worked on the base mount for that bench. I chose a 20 degree slope (taken from that guide) as I found it comfortably and it’s a round number too.

I fumbled a bit with some pipes but the cuts and copes to build it properly are more demanding than the time I had, so I settled on some channel iron. The math is a lot easier, I just needed to offset one cut by (channel width) * tan(20°) or 2.6 cm.

I’m very pleased with how I managed to make this weld around the corner in one pass:
