Angled dovetails

Some more – increasingly rare – time in the shed over the last week or so, and I started cutting the top shelf for the desk.

While I had the desk assembled to this stage the last day, I scribed the top shelf angles with pencil and set the board aside. Then this week, after thinking about it a bit, I double-checked the angles of the sides of the walnut board – because it’s the core around which all this is built – and then I used the angles of the walnut board, and the width from the scribe marks (and yes, I double-checked that the sides were plumb to the desk before scribing), and used those two to cut the top shelf.

I didn’t cut them according to the scribe marks’ angles because there’s a little bit of twist in the sides (not much, maybe 4-5mm over the full length of the sides, and the sides are poplar, not oak) so the top shelf should be pulling them back to the walnut board’s angles, not locking in their twist.… Read the rest

Creak…

Shed time again (yes, it’s been a while, work stepped up a notch and it’s been a bit miserable and chilly here (granted, not -40C but you can’t move in my shed very much so you feel the cold rather a bit). Chopped the last housing joint and then spent some time wrestling with pieces that are definitely too large for the shed to do a test assembly.

Rather awkward to put together (and those clamps are the largest I have, they were comfortably large enough to make the workbench with padding on the clamps and still they only barely make it).

That’s going to dent the outside corners of the edges, but that’s okay, they’ll be shaped to a round profile and those corners are coming off anyway.… Read the rest

More toys…

So at the same time that I bought the lidar, I had dropped about a hundred euro on aliexpress on other stuff as well. Most were presents or non-present things for xmas or general stuff like torches, but a few were just for me to play around with on the Raspberry Pis that have been building up around here — an old project came home from work and I realised I had one Raspberry Pi B+, two Zeros and three Zero Ws, one of which I had ordered back in October because I had literally lost one of the two Zeros in my toolbox.

Yes, you can now lose a complete linux computer (which costs a fiver, I’m not rich) in your toolbox. It doesn’t even have to be that full.… Read the rest
