Because the radio systems of the '40s and '50s, up until the invention of the transistor and solid-state electronics, was all vacuum tube, and these things run at very high voltages and generally low current/amps to keep heat buildup to a minimum. It was easier to step up 24V with a transformer...

I'll say something that will likely make me unpopular, but here goes... if you don't wear your seatbelt while driving on the road you are either woefully ignorant or an idiot. Let's say you get in a wreck that flips the vehicle. Do you think you're going to be able to evaluate what's happening...

Wouldn't a .50 BMG punch a hole right through one of these? What about .30 AP?

I plan to run a 4-door soft top with canvas cargo cover. I'm sure an expedient 'camper' would just involve a sleeping pad and sleeping bag... perhaps a bivvy bag if there is some leakage of rain water at the seam between the 4-person top and cargo cover. This would be as good as any tent in the...

Heard from GovPlanet on Tuesday. They emailed me to tell me that I needed to fix something on my EUC application, but there was no specific mention of what needed to be fixed. Looking at the EUC Status on the website, it said 'Corrections needed.' I looked at the PDF of my EUC that I had...

As others have pointed out, the type of questions being asked by the original poster indicate that a surplus HMMWV is not the right vehicle for him at this time. The $10K or more he'd spend on buying one plus the couple grand to get it delivered plus the grand or two to get a decent, low mile...

Given the price of new Goodyear MT/Rs, it's cheaper to buy the Black Rhino 17" rim's and the equivalent 17" tire. How big in diameter can you go with the stock suspension before tie clearance becomes an issue?

I have a 3400 sqft house, with heat pump AC plus a gas furnace (I can force furnace-only in 'emergency' mode). Big screen TV, gas appliances, microwave. I have a 6KW/7.5KW 'start' gasoline Troy-Bilt gen set with a Briggs &Stratten engine that has worked well for extended outages here in the...

I called them today. Yes, they have my EUC. It hasn't been formally examined... still in the Inbox/queue for processing (two weeks). The customer support rep gave it a quick scan and said it looks good and should be good to go, but he also said he's not the final arbiter of 'done' and the...

Is 'EUC form printed' the appropriate status until you get confirmation they've received the EUC?

Hey guys, trying to figure out what's up with my EUC. The status has changed to 'EUC form printed.' I filled out the form online, printed it, signed it, re-scanned it back in along with my driver's license and emailed it to 'EUC@govplanet.com'... and haven't heard anything. The email didn't...

That's why I'd want some sort of proportioning valve that would balance the flow back to the radiator and through the core, depending on the position of the 'heat' control in the cabin, e.g., when fully shut/cold, 100% back to the radiator, when fully open/hot, 100% flow through the core, at any...

It will get there because the level of water will equalize across the engine, but it will not flow as well due to the longer effective path for the coolant to take increasing resistance to flow. If you have two pipes of the same diameter hooked up to a common source, the shorter one will have a...

I'm not an expert on turbos or engines, but I've rarely heard of a turbo injesting something hard like a nut and shredding the impellor and NOT damaging the engine. If it didn't, you are very lucky.

I don't know much about HMMWVs and just enough about engines to be dangerous... but isn't a water temperature of 235F high for an idling/non-'working' engine? Has anyone installed one of the Paradox rear cylinder cooling kits, or something similar? I wonder why the rear coolant passages from the...
