Ridgid right angle impact driver

So in fact, you can't plug it into a domestic wallsocket at all as it'll fry the socket.

Providing the fuse / breaker doesn't go, 40A through a wall socket for a short period won't be a problem.

They did say they'd need a long one in their case. I use a 50m one at home sometimes, and when I do electrical work on my boat in the yard I need two of them ...

Two 8.7V drops.

About 1/2 an hour ago. & the impedance of 2.5mm2 cables ~0.01Ohms/m so the above calculations optimistic.

That's the surge current. Your wall socket is perfectly happy acrrying that briefly, that's why you can use fuses.

Hey folks,

Can we get off the extension cord business? Believe me it is a problem in my case. Putting the theoretical issues aside, I have tried using a common pancake air compressor with a 12 gauge extension cord in a typical commercial garage outlet and it is touch and go. If the power source is well engineered, a 10 gauge, 25 ft extension might work, but I can't or won't take the chance that a typical socket available to my installers and repair technicians will be capable of supplying the power to a typical pancake compressor with its high starting current requirements. Even with the motor being unloaded during startup, the draw (especially at cold temperatures here in Michigan, USA) is quite high.

Please, lets address the torque issue. I have never tried a nitrogen tank. I am a little antsy about having a tank with the type of pressure a nitrogen tank would have. As far as the air on a truck. Yes, that would do the trick, but I don't want to tap into the air supply of a truck I am working on. There is a lot of variation in the type of trucks I am working on and I am trying to develop proceedures for an "idiot proof" way of working on them. I need to be independent of problems with the power sources I will be encountering. That is why I am interested in mostly battery powered solutions.

Presumably an 18V Milwaukee with a universal joint can't reach?

Is this a hammer drill/driver? I thought of a right angle drive for one of the standard impact drivers. I was concerned that I might tear the right angle driver up. Maybe an impact universal joint is a thought, Hmmmm.

I was assuming that you were in the UK, (UK.rec.cars.maintenance).

Over here all trucks have ISO test points, which are a fitting standard to any truck, enabling air to be drawn out of the system regardless of vehicle make.

AFAIAA, there is no battery powered device available that would have the sort of torque required to remove seat bolts, except a cordless impact wrench, which would not fit due to access limitations.

Nope, they do real impact wrenches

I dispute that. There should be a quoted figure for voltage drop on the cable specifications.

Why? Just make a pipe up with the make connector on the end so you can plug the red line into it.

However in the case of artics, the trailer air feed pipes are all the same.

More and more you confirm that you are far from qualified to work on trucks.

TBH Simon, with the bullshit about cables and the bollocks he posted above, I don't think I'd let him near a truck with a duster, let alone tools.

Dispute it all you like. I was using Ohm's Law and the properties of metallic copper, though, and neither of those yields to rhetoric!

You know, you are right!!! That is one reason I am NOT going to tap into the air supply! Last time I fooled around with an air supply, a bunch of wasps had clogged the line in such a way that when I pulled the relief valve, the brake RELEASED! Can you imagine trying to stop a

10 ton military FMTV truck standing outside of it while it was rolling down an incline? Lots of fun, I'll tell you.
