Isn’t that just asking to be knocked and fall apart?

Hard to see but bent into 20ish degrees on each end
I did one where I bend some into a U and solder both front the top but I don't recall which one

Hot damn that's a lotta flux
Yeah. I don't give a shit anymore.
Soldering from the topside, you'll never get it all. So why try.

No more than any other surface mounted component.
I wouldn't do it to mount a footswitch or anything taking impact, but for an opamp or SOT-23 transistor it'll work fine.

Is there a way to delete Tayda drill templates? I have a bunch saved and some of them are incorrect but I can't figure out how to delete them, and I don't want to bother Tayda. They will be like "did you triple check?"
The closest I’ve seen to that is an “archive” button when you click into the edit page. It keeps it from showing up in your list.

ever since i got onto this particular solder recommended by @Nostradoomus it has made everything so much easier to clean.
the flux is fully water soluble / washable.
im not kidding, with this stuff you could just hose that build under a hot/warm tap, dry it off with a hair dryer/decent fan and have it coming out spotless with shiny joints all round
I'll give it a shot. I'm overdue to replace my Kester 44. Ordered some as well as more goodies direct from ChipQuik. No promises I'll clean it though. Got some of those desoldering sticks bean posted as well.

For those interested this appears to be a smaller spool on Amazon. https://a.co/d/7eq9o8U This is supposed to be better than Kester?

This is something that’s been bugging me lately! I’m used to using ribbon cable but my latest project has the daughter board so close to the pcb that I’m gonna have to use this method, leads or buss wire. What’s the best order to do this? Do you just fasten everything in the enclosure, insert the leads and solder to the top of the pcb?
It depends on if it's a straight.vertical shot or at an angle. I try to layout my drilling for vertical shots when able.
I'll dry fit first, just to be certain I didn't screw up. You can dry fit it to test if you need an angle. Sometimes you might need 10-15 degrees. If all align, I'll solder the header to the PCB, put it back in the enclosure then drop the 3pdt on it.
In the case of the above photo I just ballparked with everything in the enclosure with a slide rule and bent the header, after scooting the plastic bit up, iirc.
As long as you don't contact the switch housing with the header, no real reason to trim them. Just solder in place.

it's not really a case of 'better', it's just another option and i like it.
i've never used kester.
also there's like a hundred different types in the kester range, so when asking this question, you need to be comparing apples vs. apples.
e.g.
- tin/lead ratio
- various ratios of lead-free (for those that need or prefer lead free)
- flux type
- flux %

You’re right. This is what I use. https://a.co/d/36vaVYz

Reuse them, just change the name and delete all the holes.

Yeah, other than archiving old versions, do like Robert suggests and repurpose. It really only gets problematic if you don't keep track of names and/or you have them shared.

What’s this little two pad 1144 thing under the top left IC? It’s on the God City Thing that should not be pcb

I found it! It’s a place to put a jumper wire if you use a LTC1144 (or whatever charge pump ends in 1144). You find it by where the charge pump is in the schematic with a note.
Should be jumpered when using an 1144 charge pump. These normally have a switching frequency around 10 kHz, but connecting pins 1 and 8 allows you to boost the oscillator frequency well outside of the audio band.
