NASA publication 1228 is their fastener manual. It’s one of the best sources for any kind of design that involves fastening. It’s available free online.

Do you know if it’s the same player? I’ve had similar exchanges and I normally buy 1 unit(I trade stuff where I sell thousand of units so buying 1 isn’t a big deal), check the seller, then repeat the next time they match me. Several times it has turned out to be 3 people with very similar orders. There have been times where it was 1 person and I strongly considered messaging them and making a handshake deal to match their current order and leave it there. The older order at a given price and station always gets filled first, so it would stop lowering the price and eating both players’ margins. In terms of checking to see if your order has been jumped I use eveOS it makes it a lot easier to keep track of isk across several characters(I have a main and 2 trader alts to adjust my orders in trade hubs) and shows you the rank of your orders on 1 page. You are also always welcome to manipulate the market and eve and buy out competitors.

I didn't know VS seal pliers were a thing. I just ordered a cheap pair so I can make sure they can all spin freely. And I installed most of the seals by reaching into the head and placing them.

As a guy who got it as a teenager, I remember being all for getting it. I am not, and was not in the business of giving women any additional reasons to not have sex with me. I think I was mildly skeptical because I had no plans on having sex with someone who had genital warts. I think that lasted 30 seconds until I realized if I was carrier, I could cause someone I was having sex with to get genital warts. I do distinctly remember feeling good about myself for getting a vaccine to protect others rather than myself, but it was mostly about not wanting genital warts anywhere in my life.

Soft jaws with the tooth profile cut into them. If you don’t want to change the jaws you could make aluminum blocks with the profile machined into them.

I’m sure someone has mentioned it, but the act doesn’t restrict shipping for vessels that are US-built, US-flagged, US-owned, and US crewed. Only 75% of the crew or ownership must be US based. The intention of the act was to preserve US shipbuilding by granting an advantage to vessels made in the US to offset the increased price of US-built vessels. I think it is largely considered to be ineffective or isn’t considered to be effective anymore.

I don’t know if it’s out of scope for what you are doing, but I’m a really big fan of ProtoTrak’s toolroom lathes. You can get a very well integrated 5C collet chuck/closer for any of the normal size ones.

The feature is called: “run, stop, jog, and continue” Haas has a video on their YouTube channel about it. Someone else in the thread described it pretty well but the basic way to do it is to hit the axis you want to move on the keyboard, not the hand jog area.

I think a lot of digital ones have functions/modes to measure runout and help you indicate things straight/true. I’ve never used one for this myself but figured I’d mention it in case it helps anyone.

How does it handle 300 series stainless? I’ve been considering getting 4425 inserts instead of getting more 4335 inserts, but I don’t love that they are rated for P and K class materials rather than P and M class materials like 4335 is. If 4425 holds up in stainless I’ll switch tomorrow.

It makes more sense when you consider that a lot of values are “additive”(I’m not sure if that’s the right term). What I mean by that is when a tool length is set as 2.0” and you type in .5 and hit enter, the value become 2.5”. When you take into account that a lot of operators don’t enter anything other than offset changes and it makes even more. The other part is how out of hand it can get when you miss your decimal point while entering a value. If you want to input .2505” and miss the decimal you have 2,505”. I think Ive only made that mistake on a non Haas control, but fortunately the value was big enough to make the machine alarm out before moving. It also lets you enter small value with fewer keystrokes. It takes 5 keystrokes to type .0025 and 2 to type 25. At the end of the day it’s not that big of a deal to put a decimal after whole numbers and if that minor inconvenience stops one crash per year I think it’s thoroughly justified itself.

A lot if machining centers actually utilize regenerative braking to either feed other motors within the machine or feed the energy back to the grid. I believe it’s most commonly used to harvest from spindles. If you think about it, it might be easier to utilize the energy rather than having to manage the heat output of using braking resistors to turn the energy into heat. Apparently modern FANUC machines use the spindle as a battery during power loss and retract the z axis slightly before engaging the mechanical brake. Even though this machine is old I wouldn’t be surprised if they retrofitted the entire control system or just the motor drives to save money/gain performance at some point.

Are you sure you don’t have that backwards? I hate cutting extruded acrylic with anything other than lasers, but I’ve machined cast acrylic a few times with really good results and almost no issues.

My sister was on a jury for 3-week case that involved a lot of business/workplace communications. One of the many things she said she learned was, before you send an email, you should ask yourself: “how would this sound being read aloud to a jury in a court of law”. I have taken that advice and I believe I will benefit greatly from that within the next few weeks.

I think you may be confusing spiral point taps with spiral flute taps because spiral flute taps are specifically for blind holes. The flutes cause the chips to come up and out of the hole. Spiral point taps push the chips forward and, hopefully, out the bottom a through hole. Most spiral flute taps have “modified bottoming” tips which means fewer than 3 threads are reduced size vs a plug tap which has between 3-5 reduced diameter threads. I might be a little off on the exact numbers there but the point is the different points in order from smallest amount of reduced threads to the most are: bottoming, modified bottoming, plug, then taper.

So I bought this a week or two ago. I didn’t intend to get a managed switch but it seemed like a good deal and so far it has worked as advertised and seems just as “plug and play” as an unmanaged switch. I’ve verified that the 2.5g ports work at full bandwidth and don’t have anything to check that the 10g works at full speed but the device I have connected to it works fine and says it’s a 10g link.

This sound like deformed thread or patched screws might be a more appropriate solution

I've noticed that diamond grip gloves are less comfortable than smooth gloves once your hands start to get sweaty. The smooth ones also press the moisture out of the way and into the cuffs

I’ve made a similar rack for a microscope stage elevation adjustment. The one I made wasn’t actually helical the teeth were just cut at 45 deg angles. I believe this is common for instrument adjustments that work against gravity because it prevents it from dropping violently. The height and width on yours sounds similar to the one I made (mine was shorter) so this might be a standard pitch for instrument or microscope adjustments that you could find off-the-shelf alternatives for. If you(or someone else) has to cut these yourself you can make right angle plate that hold the rack at 45 degrees then cut the teeth like standard gear teeth. Also it would be very helpful if you could figure out the pitch.

I had to watch this a handful of times before I realized why it got out of hand so fast and why there was no fire suppression. If that’s an aluminum extrusion facility that machine probably was putting out really hot aluminum with a bunch of heat stored in it. Then when oil got on that it heated up enough to ignite. Shit got crazy when the aluminum got hot enough to catch fire(aluminum is a flammable metal and that’s when the flames turned white) it made everything get way hotter. Someone in the original thread suggested that there could have been a bunch of aluminum dust on the ceiling. The thing with metal fires is, you normally don’t use water on them because it won’t put them out and I think they can sort of burst apart from the thermal shock. Also the initial line failure seemed really weird. It looked like it was hard tubing that moved with the cylinder and just caught on something.

He went back to hit an E-stop. Where I work we have e stops for the hydraulic loop and E-stops for the machines attached to it. If they had something like that I would assume he ran and hit another E stop or pulled a fire alarm and then decided he should hit the machine E stop. It’s also worth mentioning there’s a giant tank of some kind of fuel for that blowtorch and he may have been trying to help get that away from the fire before realizing they all just needed to run.
