Not sure if the specific instances being referred to, but this generally comes from a lifetime working in shops.
The term “**** off” is widely used for these situations “in the shop”and really no one is worse for wear inside the shop, but it really doesn’t translate well to civilian life.
When I was working in my first proper job, back in the 90s, doing a mixture of writing production and incident tracking software, writing pretty much 'ladybird book' level PLC control routines, plant networking install and maintenance and a bit of general IT support ("Hey...compudah guy!"
) for Cosworth, I had occasion to walk into the maintenance tech's cage and there, about 10 feet off the ground was the newest apprentice, cable tied to the cage in cruciform position. Apparently, he'd been playing up again and the technician's patience had finally worn thin.
Now, this lad was a pain in the arse (he'd spent two weeks shadowing me, and I spent more time during that fortnight trying to get 10 minutes work out of this surly little scrote than actually teaching him anything; he wasn't even entertaining or funny in the way some teenagers can be) and his dad who also worked there had
only very reluctantly got him an apprenticeship position there.
When his dad walked by, back from the company canteen, and saw him, he just shook his head and asked the technicians "what did he do this time?". To be fair, the lads did get the little oxygen thief down out of respect for his dad, but later on I overheard his dad having a word with him quietly saying "If you're going to insist on being idle and swing the lead, you have to at least learn to get along with people and have them like you!" Those words really stuck with me (not that I successfully practice the wisdom, I'm an aggravating arse if I'm honest!
).
Thing is though, that was in a production facility. I've learned a lot from Joe Pie and have a metric crap ton of respect for his abilities but frankly, I don't think I particularly like the guy.
The crazy glue thing works well enough even though I was initially a skeptic, but it does have a dangerous downside so maybe that’s his issue with it.
If you get the glue hot while machining it will flash off and the fumes are horrible, hazardous and could lead to an accident.
It’s a tool in the toolbox, but should really be used sparingly.
Superglue can be very handy but like you say, it's suitability for workholding is dependent on the scenario.
Maybe Quinn knows, given the hobbyist machines she has, and the low tool pressure she will be limited to, that she's unlikely to heat up the part where that might happen; I don't know but she seems to be pretty switched on about safety.
