Back in the Google+ days, I followed Noah Friedman, and I enjoyed his horological posts. I know nothing about this hobby, I just liked the pictures.
Bartosz Ciechanowski has a gorgeous web page explaining the inner workings of the mechanical watch, a few parts at a time.
I think I finally understand why it wandered. Read an eight-year-old thread on hobby-machinist.

Actually a dozen more. I forgot two spacers in my count. ☺
13 total parts to machine. I guess I'm lucky!
This is the first part I've made for my keyway cutter. Ten left. This will take a while.
I've never before bored a hole this long with such a high aspect ratio through steel; ⅝" almost 5" long.
First try, I broke about an inch off the end of my pilot drill right in the middle and after a lot of work failed to rescue.
Second try, I used a larger 3/16" 6" aircraft drill as a pilot, but it wandered. I ended up using a 2-flute ⅜" end mill in both ends for alignment and drilling through, which got me close enough for final drill and ream.
I forgot to chamfer before starting my final reaming operation on this part.
Now I know why to chamfer before reaming. This chatter is intense, and it's definitely just as bad as it looks.
😅
Fortunately, I can start over from the other end and these chatter marks will, I think, eventually do me no harm.
I guess it's just click the mouse a bunch of times after typing the PrintScreen key. It's a lot of extra mousing around for something that used to be really easy. I wish that the old keybindings were still honored, even though the new experience is probably a lot more discoverable for others.
When I bought my big lathe, I didn't get rid of my mini lathe.
I have work currently set up in the big lathe, my bike's front brake broke, and the bike stores were all closed.
Quick chucked some AL in the mini lathe, turned a new Bowden ferrule, and I'm back in business!
Not the first time I've used the mini lathe to avoid breaking down a setup on the big lathe, either!
After a long hiatus, a new Clickspring dropped!
This is worth a read. I continue to mask in public, and I'm becoming less interested in eating out. Again.

I'll claim substantial credit for this one, five and a half years after I left. SAS's Viya was my idea, as was the idea that Python should be a first class language for using it. The idea that you should have to learn a weird variant of PL/I to use sophisticated analytical software has been doomed since before my stint at SAS, but that view wasn't very popular with Dr. Goodnight. ☺
I'd love to be able to follow Discourse posts in categories or by people automatically in mastodon.

Passing on lathe skills to the next generation. 😎

Donald E. Knuth did it!
"The Art of Computer Programming, Volume 4, Fascicle 5" is out!
A sad thing, though, is that Prasimix reports on the eevblog forum that Crowd Supply isn't getting lots of traction. It's sad that a site that last I heard had _never_ failed to ship a successfully backed product would have trouble promoting their campaigns.
Open source hardware. And firmware. And software. I'm 🤞 on the Envox BB3 launch. I like my H24005 and want the upgrade. Prasimix has done great.
All of this is open source:

He's not holding back designs until after a successful campaign, either. It's all on github: https://github.com/eez-open
