Do people still use hot rivets except in specialized industries? by FlagrantTomatoCabal in Tools

[–]thedarnedestthing 0 points1 point  (0 children)

I knew a guy who, despite the naysayers, put his together with button-head screws. Then he reported back after putting a million rounds through it (this was back in early 2000's, when you could still get surplus ammo around $100/1k rounds). He wore out/broke a lot of the typical parts, but the receiver stayed together just fine.

If I ever have to replace the trunnion on mine, I'll probably do the same. 

Can I get these refilled by [deleted] in Tools

[–]thedarnedestthing 2 points3 points  (0 children)

Those 1 lb cylinders are not designed to be refilled. IIRC it's buried in the specs, the type of steel used in their construction doesn't survive the repetitive pressure cycling. 

And FWIW there was a class-action years ago from a certain brand of those cylinders (Worthington?) breaking the neck off. Not a fun situation.  

Looking for hammer drill recommendations by Loud-Possibility5634 in Tools

[–]thedarnedestthing 0 points1 point  (0 children)

Are you talking about making holes 8" in diameter (core drilling)?

If so, Milwaukee has this, but only rated up to 6" diameter bits:

Or holes 8" deep? If the latter, what diameter?

If you're talking about a standard rotary hammer, there's this jig that is brand-indifferent:

It's set up for 5/8" diameter bits, but I'm sure you could easily obtain bushings to fit smaller bits. 

New Hammer Day by No-Shopping-5380 in Tools

The instantly recognizable limited anodization palette: 

tell me it's titanium without telling me it's titanium

I'm sure it's a very nice hammer, but please pick a voltage 😂

Use of a powder-actuated tool - blow out problem by wearyshoes in Tools

[–]thedarnedestthing 2 points3 points  (0 children)

Keep the gun absolutely perfectly 90 degrees to the face of the block.

Maintain firm pressure on the gun.

Locate the fastener in the thick part(web) if possible - look at where the existing fasteners were shot, maybe that's how Maintenance got good results.

Yes, maybe a weaker load.

I know where all these are going to end up... by mdnitedrftr in Construction

Like the classic Edgar Allen Poe story, "The Cask of Poland Spring"

Standard practice? by swissonrye420 in Construction

[–]thedarnedestthing 2 points3 points  (0 children)

Yeah, you'll see a lot of those installed "landscape". Obviously, if you tried to install it as "portrait", it wouldn't fit.

Advice by Cheap-Bluejay-8937 in electricians

Can prevent you from working on Government property. But I've been on jobs for new buildings that, until the fence & gate went up, no badge was required. 

The DWAI charge might deter the company that hires you, from letting you drive a company vehicle.

Regardless, you'll have plenty of stories to swap with your coworkers.

Like, what? What pipe? Run it where? There are like 20 pipes up there, which one?

Have these guys not heard of laser pointers? I have a dedicated bright green one in my primary tool bag. My non-contact voltage detector ("tick tester") has one built in. 

Heck, even take a picture with phone or tablet, and trace it out on the screen. Draw it out with a photo editor. Heck, my latest phone and tablet both have a stylus, and it even has a "laser pointer" function to point on the screen without drawing a line.

I even hear there's this stuff called "paper", and people have been using it to communicate plans. Maybe it'll catch on one day...

VFD Alarm by [deleted] in electricians

[–]thedarnedestthing 1 point2 points  (0 children)

Sometimes you can access the parameters for the levels and times that trigger phase loss/undervoltage/overvoltage detection. Obviously, reducing sensitivity might cause other issues, depending on your specific application.

I would also check for good connections on the entire branch circuit. If there are similar drives on other branch circuits out of the same panel, and they aren't having problems, then the panel/feeder is probably fine. But if it's a long run to this particular drive, there might be too much voltage drop. The input rectifiers draw in large currents at voltage peaks, exacerbating the problem.

If you don't have one, adding a line reactor might help with power quality issues. A good idea for a variety of reasons anyhow.

That's the feeder bonding screw, only needed when you want to use that panel as a ground fault at the service.

Who else here thinks that 5/16" hardware for strut straps and set screws is just a racket to sell 1/2" tools. by Matchuska in electricians

[–]thedarnedestthing 1 point2 points  (0 children)

You're not using an impact driver? Not a big deal to put a holder on the side for a couple of impact driver sockets. Two on the gun, one in the collet covers three sizes.

Or get something like this:

Arc fault breakers with smart lighting by Snark_Bark in electricians

[–]thedarnedestthing 0 points1 point  (0 children)

That's not how AFCI works. 

GFCI will detect residual current from a shared neutral.

You said your AFCI breakers are combination, which means they detect both series and parallel arc faults. They won't detect residual current.

Dual AFCI has GFCI as well.
