Wouldn't an impact wrench have been a more appropriate tool in that case?
Yes it would, but I didn't have one available at the time.
Or a regular wrench + a good number of firm taps with a hammer?
Tried that before breaking out the jack.
An 18" lever and floor jack sounds like a good recipe to break off a frozen bolt.
Yeah, it is a lot of times. After the first attempt, I let it sit for a couple of days with penetrating oil on it, and I had the drill ready to go if things went south. I was frankly surprised that the bolt *didn't* break, and even more surprised that the threads were perfectly clean, with just a little bit of blue Loctite on them.
Those parts are bigger than the output. The highest force is applied to the output, not the ratcheting mechanism, because the output is of lesser diameter.
That's assuming that the fastener is the smallest element in the system, and things get worse very quickly when the fastener is substantially bigger than the drive. In my particular case, it was a 1/2" drive on an 18mm socket, and it was the drive that broke. The size of the ratchet head was about an inch, so I'm guessing the ratchet itself was also around 18mm. Ratchet survived, but was kinda useless without the drive, and it wasn't worth it to open the wrench up and replace it.:-)
Having said that, I hadn't thought about grossly oversized ratchets/drives in conjunction with small fasteners. If you're turning a 1/2" bolt using a Hulk-like plastic ratchet with a 1" drive, you will have a lot more mechanical advantage to work with.
If a finer part of the tool survived but a thicker broke, doesn't it seem very plausible that the tool was either badly designed or that the manufacturer have problems in their molding process.
I guarantee that was the case (although steel hand tools are generally forged, not molded) - it's not like I was using a high-end Snap-On wrench. Just the same, the crappiest steel tool is going to be stronger than any ABS tool of comparable dimensions.
You are talking about managing to break a hand powered tool. With a good design that have been correctly manufactured that shouldn't be possible. Plastic or steel, it is perfectly possible to create ratchets strong enough that your arm will break before the tool.
I also mentioned that the bolt was tight enough to require a floor jack to get enough torque on it, so it was under far more torque than any person could apply. That *still* should not have been adequate to break the drive, but it did. It's possible to make very strong ratchets with a variety of plastics in a size readily usable as a hand tool, but neither ABS nor PLA is one of them
3d printers are working in metals now. Carbon fiber as well.
The one in question doesn't, so this statement is irrelevant to the discussion.
I don't know how to deal with someone with so little vision that they can't understand the value of fabricating tools on site when the alternative costs thousands of dollars a pound and has turn-around measured in months.
Spend as much time as I have in tool manufacturing facilities and working with engineers to optimize production processes (including 3D sintering, which already was old news 10 years ago), and then once you've done that, go back and read the original post and explain where "little vision" comes from. I said nothing regarding 3D prototyping/manufacturing in general, but you'd know that if you actually read what I wrote.
" So I'd ask you to just stay away from the Internet."
It certainly doesn't sound like it when you jump to the conclusion that the largest and sturdiest part of a tool would fail before the fine tool end that contacts the nut.
I'm not an M.E., but I've seen enough drives/ratchets break with intact sockets (and no, they weren't impact sockets) to know that one can't make that statement categorically.
It's not a contrived (that means "unlikely and made up for the purposes of the argument", BTW) example - it actually did happen, and happens more often than you might think. Just because a good portion of the ISS was built under ideal conditions doesn't mean that fasteners can't stick. There are parts that have been in space for more than 15 years, after all.
But to respond to your statement directly, no, a metal socket isn't going to help the first bit when the drive, ratchet, or handle is made of a flimsy plastic like ABS or PLA, even if it's injection molded. If the fastener is hard enough to turn that it breaks an ABS socket, then it's going to break the wrench instead when you use a steel socket on it.
If you attach a metal socket, it's probably quite capable.
I wouldn't expect a lot. I snapped the solid steel drive on a 1/2" ratchet right off the last time I did my brakes trying to get a frozen caliper bolt out . It took an 18" breaker bar with a 3/4" drive in combination with a floor jack to get enough torque on the breaker bar to finally get the bolt loose. I don't foresee an ABS tool handling that kind of stress.
Not even that, Visual C++.NET is a broken aberration that I have not seen used anywhere ever
C++/CLI gets used plenty, but mostly in places where straight C++ has to interact with other managed code. It works, but C# is a *lot* easier to deal with if you're staying completely within the managed environment. If you don't have the need to mix them, you likely won't see it. In my case, I've had to use it both at my current job and the one previous when integrating legacy C++ code with newer.Net stuff.
A friend and I had some fun at the Jehovah's Witnesses' expense about 30 years ago. I was over at his place, and there was a knock at the door. He peeked outside and said "Dude, it's the Jehovah's Witnesses, come here!" He threw his arm around me and answered the door in a very lispy voice, and they were mostly speechless. He then looked at me and said, "Well hun, I don't guess they have anything to say, so let's go back to bed!" and shut the door on them. He never got another knock again.
I mean, I didn't have to sign it but i'd not have got the job otherwise. Doesn't mean you agree with it. Hell, doesn't mean you're going to obey it, but all that comes later.
Then you weren't willing to walk away from it. Signing an agreement you have no intention of keeping can be a recipe for a lot of expense later on.
I've walked away from bad agreements, and I'm not shy about crossing stuff out that I don't find acceptable. So far I haven't had anyone refuse to hire me because of that. As Billoo said, you have to be assertive about your own best interests because you're the only one looking out for them.
In the U.S. there hasn't ever been an exploitation requirement per se. The only kind of IP that explicitly requires action by the holder is a trademark, which they're required to aggressively defend at the risk of losing it otherwise. However, it used to be that you could file an application and tie up the approval process for years without it actually being issued, which effectively let you secretly hold a patent as long as you wanted and have it formally issued only when it was to your advantage to do so. About 20 years ago the U.S. changed patent terms from "date of issuance" to "date of filing", so the clock now starts ticking when you first send in the application.
That 90k job will have at least 10 hours of unpaid stress/OT vs a 65k/40hr week so the coefficients to compare are 1.625 govt vs1.8 private sector.
Except I already make more than that and do a 40-hour week, and I haven't been given any grief over my vacation schedule. In my situation, the pension would be the only notable benefit. And our department hasn't seen any layoffs in literally decades.
While many places will pass on the basis of a felony record, one of the best Java guys I ever worked with had a felony assault conviction from about five years prior after a guy started a bar fight. He was a contractor when we met, was hired by the company we were doing work for, and hasn't seemed to have too many problems finding work. He was also very up-front about the conviction during the HR process.
Another thing that employers sometimes like to pull with salaried employees is not paying a full week's salary when there's a day or two when the office is closed during the week (holidays, etc.). If work was available at all during the week and you were willing and able to work, regardless of the number of days the office was closed, you're supposed to get your full week's pay unless it was the first or last week of your employment. If an employer has a policy that formally disregards that rule, or doesn't have a policy but regularly violates the rule, they risk losing the exempt status for their employees at that location.
Date libraries, as it turns out, are rather monstrously difficult to make.
They're not too bad if you have only the U.S. to deal with, but throw awareness of time zones worldwide into the code and it becomes a mess quickly because of all of the 30 minute, 45 minute, etc. changes. I had to write a separate date library for an airline reservations system many years ago simply because the stock C++ libraries wouldn't deal properly with Australian time zones. Maybe that's changed since then.

Says the AC. Whatever, dude.
Absolutely, assuming you have the room to turn it and can otherwise get the wrench onto the fastener.
Yes, on space stations.
It certainly doesn't sound like it when you jump to the conclusion that the largest and sturdiest part of a tool would fail before the fine tool end that contacts the nut.
I'm not an M.E., but I've seen enough drives/ratchets break with intact sockets (and no, they weren't impact sockets) to know that one can't make that statement categorically.
so the force increases as you get closer to the nut/screw.
You're absolutely right, which means the *ratchet and drive* are under the highest stress.
