Yes and no. Vinegar is great stuff. It's my favorite carburetor parts cleaner. That said, the chemistry of using an acid (acetic acid in this case) is completely different from using a base (alkali) as your rust remover. All acids etch metal. A salt, by definition, is the result of the...

Yes, this works great on exhaust manifolds. An exhaust manifold was my second test part when I was in the 'this is too good to be true' phase of experimentation. Remember, though that the sacrificial cathode has to be in line of sight from the parts you want the rust to disappear from. For...

Looks like it's one of the late production B-25 J models. Most of the survivors are. A very pretty example.

I'm asking. Give me more.

I use both the electrolytic method and Evapo-rust. Evapo-rust works great, but is expensive. Electrolytic works great and is cheap, but requires a good electrical connection between all the bits you're trying to derust and the anode source (it's an alkaline system, so you have a sacrificial...

Sobering reading. There's one thing to watch out for, though - as long as Beijing continues to have a strong trade relationship with USA that keeps a majority of urban China employed, you can bet that they're not going to disrupt that with an EMP attack against the US. They simply don't have...

I got my generator filters there as well. It's worth mentioning that if you have an older car or truck, it's a good idea to search for consumable parts for it at Rock Auto periodically. They buy up old parts stocks and sell them off very cheaply, as in oil filters for $2, Brake pads for $3...

That's a great idea. I like the pad, the easy-dismantling shed, and the heavy insulation. Seems that a little extra work would help with sound management as well. What does the freezer panel cost and what sizes does it normally come in? I'm guessing it has a pretty high R value given the...

To do it right, you would have to make sure the ground rod was right there at the generator (which is a violation of NEC if you're using the generator as a backup generator to a normally grid-connected house). But yes, if you're concerned about EMP, grounding and shielding everything is...

I'll mention that I did something very similar to this in a critical domestic situation - we had run out of home heating oil on Easter morning in PA. It was 28 degrees and snowing at 0730 when the house dropped below 55 degrees. The solution was a 12V Facet pump, about 30 feet of tygon hose...

It sounds like a lot of runtime, but a little quick math shows that it's the equivalent of 30,000 miles at 50 mph avg. The engineering is not dissimilar from an over-the-road truck, and they go a lot further than that between overhauls even without oil microfiltration. I suspect that it's all...

It's a pretty safe assumption that pulling a vacuum on the fuel system wouldn't encourage operation. Have you tried running it with the cap attached loosely? You might be able to run it with half a tank of fuel, the cap removed, and the strainer in place to limit splash.

Depends on seal compatibility, but generally yes as long as the viscosity is reasonably close to that of water.

I've read about these, but never seen one either. Pics, please!

The last time I saw a Goon (a C-53 in this case) earning its keep hauling stuff in CONUS was about 1995. A guy running a small airfreight firm had one in his fleet along with the mid-size turboprops and had several UPS airfreight contracts. He used the goon for the RDU-ILM run when there was...

Shrouding at low pressure differentials is not a big deal - if you're within 1/4" or so of blade tips you're fine. What you really need here is a plenum - that is, the shroud needs to surround the fan so that the air is pulled evenly over the entire radiator core before it's sucked out by the...

One number I haven't heard from anybody. Is there a recorded CFM value for the engine driven fan anywhere? It would be sized for the worst-case Death Valley in July fully loaded with a loaded trailer case. Most people with deuces woudn't need to match anything like number. But it is a useful...

Just to fill in a little here - most people who seriously drive Corvairs have gone to electric fuel pumps. Nobody seemed to be able to make an E10-compatible diaphragm material for that pump for whatever stupid reason. I didn't mean to minimize the effect of ethanol on elastomers - I just...

You've stepped into one of my areas of competency. I worked in a vehicle emissions lab for about five years analyzing gasoline before and after it went through an engine. Ethanol makes a pretty decent fuel for an Otto-cycle engine. Not as good a fuel as toluene or 2,2,4-Trymethylpentane...

Given that you're talking about a 1950s battlefield-ready tactical truck that was expected to run anywhere in the world, I think the best gasoline to use in an M38A1 is probably liquid. Most engines with those design criteria have a minimum RON of about 75 or so, which would equate to a PON of...
