This is a guess from a non-lawyer who took a business law class a long time ago in a different state: I think it's like the UCC (Uniform Commercial Code). It's a set of laws that were written up to be pretty much universally applied anywhere and there's a push for law harmonization that has...

Very cool. I'm subscribed for sure. These are another feature of my memories of growing up on a SAC base. In fact, I remember when they built a huge new bay onto the flightline firehouse for the shiny new P-15 (which, yes, was enormous, but could probably put out a B-52). After that, the...

Turns out it's a K1. If it's a K1A1, it even has the 120MM smoothbore of the M1A1 and Chobham armor. Diesel, not turbine powered. No longer in production. It's about to be replaced by the K2, which has 300 more HP, among other things. Given that Korea is pretty much the world's shipyard...

The design purpose of that sort of shroud is to deflect the noise coming straight out the port underneath. But yes, it's also great for weather protection. No reason not to keep it as long as the area around the outside edge of the shroud is equal or greater to the hole underneath.

Great news. Do be sure to put rated load on it before you run it much more - these units like to be worked hard, especially in cold weather.

One note of caution - I never install valve stem seals on anything's exhaust valves. The exhaust system is under an average positive pressure - it's hard enough to get a consistent amount of oil down the valvestem without a seal. On the intake side I run a seal if there's a problem with...

Good work, and you're definitely going about this the right way. You've replaced ideas with numbers, and you've got all the pieces of the puzzle in place together. As you say, your last missing ability is putting the thing under rated load. See if you can find a way to measure the actual...

If you have the ability to easily check the compression (eg, glow plugs come out and you can quickly borrow/fabricate an adapter and gauge) do so. Otherwise, I'd check: 1. valve lash (can equal low cranking compression) 2. injector timing 3. injection pump shot when cranking (remove an...

They tried for a good long while to get the Sea Shadow into a museum somewhere but nobody wanted the ugly and huge floating 'parking garage' that came with it in a non-dividable deal. USS Nautilus is unusual in being a naval technology prototype that wasn't sent to the breakers later on. So it...

In answer to the various questions posed: The external shape of the ship appears to be optimized to reflect horizontal or nearly horizontal radar beams up into the atmosphere. Salt water is also a pretty good reflector, so reflecting down (as a conventional bow would) is not a good option. If...

The DDG1000 is definitely not your father's destroyer, no matter who your father was. The ship is a floating testbed for all kinds of interesting stuff. I had a very little bit to do with some of the stuff aboard her, so am more than slightly interested to see what succeeds and what doesn't...

First, if you want starting fluid, use something safer than ether - it's not kind to these engines. Used to be WD-40 was a good choice, but I don't know what works well these days. Second, if you can't get a diesel to start and you know the glow plugs are getting hot, then your problems are...

A great question. Speaking hypothetically, the "right" answer (remembering that this is criminal negligence charges level of badness if you hurt somebody when you did this) is to run a separate ground wire and bond to the house ground. Newer dryer outlets actually are four-prong so that the...

Until DoctorCheney223's 'identify my Sherman' thread, I hadn't ever seen photos of a Sherman hull without anything in it. My only exposure to battle tanks in any detailed way until then was an M1 Abrams MBT I crawled over back in the '90s. It has been fascinating to compare the complex and...

I almost added more detail on the droop setting last post, but decided against it in the interest of brevity. Now seems a good time to talk about what it is, what it does, and what overdoing it does. Basically the droop setting controls the sensitivity of the governor - it adjusts the...

So basically if I never operate in 120V single-phase mode, I don't need to worry about this. And if I do, I'm OK as long as 1) the reconnection switch is wired correctly and 2) I pay attention when connecting to the load terminals. Thanks for digging into this.

HACR, huh? That's an old breaker - the HACR rating hasn't been required for quite a while. The characteristic curve is on page 20 in this document. As I look at the curve, minimum trip time at 30A should be about 4 seconds. So as long as the start-up surge is a second or so and is <3A, the...

Well, we are talking about historic military vehicles here. They all come wrapped in history, be it mundane (like a certain M38 jeep I know that probably never left CONUS) or famous, like a Sherman tank.

Looks like you've got a keeper. Governor adjustment is detailed in the manual, but a good first step is just to make sure that everything on the linkage moves freely and doesn't have excessive slop. I have yet to hear of one of these problems that doesn't end up being linkage and adjustment...

Well, maybe it would and maybe it wouldn't. It all depends on how that particular breaker is biased for trip speed between surge and continuous current. That's a design property (just as with slow-blow versus fast-blow fuses), and you check out the spec sheet to see just what the surge current...
