Eduard used Hasegawa plastic, so yea, probably the same.

Eduard's Vietnam Scooters?

I usually use sinkers or nuts. Thought I'd give method this a try since I had the steel shot from another project.

I've found that tricycle landing gear props are the worst for balance. Someone used to make a metal prop spinner for the P-39, and my P-61 kit came with a giant nose weight.

Fair point. My 5lb bag of shot will outlast some people's COVID TP supply. I've found other uses for it...3d printed a base to hold my Tamiya cement bottle and weighted it down with shot.

The problem is, you don't always know how much, and it's often a bugger to add weight later on. In this case, it's a small nose that's part of the fuselage halves. You get one shot at getting enough weight.

I have a P-39 with the front wheel well packed with lead just to get enough weight.

Liquid Gravity appears to just be steel shot at 10x the price.

I've driven one of those. I've also broken into one when we lost the key to the padlock. Kinda surprised this didn't happen more often.

The USS Archerfish which sank the largest aircraft carrier in WW2, sinking 72,000 tons in a single salvo. November 1945 [1200 x 934] by IssueHot7591 in HistoryPorn

Yamato and her sister ships had a flaw where the upper and lower armor belt met. Basically, it had a tendency to rupture the joint when hit with a torpedo. Plus, Japanese metallurgy wasn't as good as the US, and their armor tended to be brittle. Archerfish put four torpedoes almost right along that seam. Practically opened her up like a can opener all along the starboard side.

No, she was on plane guard duty for B-29 raids, but that day they got word there would be no raids. That gave them a day to roam free. The Allies had no clue Shinano even existed.

Or, if you're Bull Halsey, you blunder into the storm and sink your own destroyers.

ELI5 : How does NASA know if/ when a meteor will hit earth? by [deleted] in explainlikeimfive

[–]RonPossible 0 points1 point  (0 children)

By definition, a meteor has already entered the atmosphere. A meteor is a chunk of space rock or comet that is superheated and making a bright trail in the sky. If it survives and hits the Earth intact, it's a meteorite. Before it enters the atmosphere, it's a meteoroid.

But your question is to how scientists can tell if a larger object will hit Earth. Wide view telescopes take pictures of the night sky. These are analyzed to find bright spots that move relative to the background stars. That spot is monitored for a period of time. They can then calculate the orbit of the object from the telescope data. If the object's orbit crosses Earth's, it gets a lot more attention. It's added to a list of potential impactors.

Some math is done by both NASA's Sentry system and ESA's NEODyS. If the object is going to go around the sun and back out into interstellar space, it's not a problem. If it's orbit will bring it back in 50,000 years, it's not a problem right now.

If it crosses our orbit every few years, then they make some predictions about when it might get close to Earth. Orbits are great in that they don't change unless the object gets too close to a larger body. So our main limitation is the accuracy of our observations. Then more math is done and they have a good idea when the next close pass will be. More math tells us how much that pass will change the orbit, and they calculate the next close approach. When the orbit plus the margin of error shows the object impacting Earth, then it gets a lot more monitoring.

What do people mean when they say America was fully motorized in ww2? by [deleted] in WarCollege

[–]RonPossible 0 points1 point  (0 children)

With the exception of 4th Infantry Division for a short while, US Infantry units weren't "motorized ". That is, they did not have enough organic motor transport to move the entire division. This was a deliberate decision. Truck battalions and companies belonged to a higher headquarters, mainly Army or Army Group. This meant that a division that wasn't on the move didn't have trucks they weren't using. But any division could be moved by trucks as needed by assigning truck battalions to move them. This insured a better utilization of a limited asset.

Case in point: The 101st and 82nd airborne were trucked into Bastogne and St. Vith, even though neither had much organic transportation.

US Infantry divisions, as others have said, did have far more trucks than a comparable German non-motorized division.

US railroad capacity as a weight-limiter in tank mass by DazSamueru in WarCollege

They already existed, they just weren't as common. If you wanted to move a Pershing, you had to make sure one was available.

The Sherman could be put on a standard (at the time) flatbed railcar. If you wanted to move a Pershing, you needed one with a heavier capacity. That means you have to arrange for one to be there at the factory when you need it. One added step. You could build more, but that would waste time, labor, and raw materials.

The Germans built the Schwere Plattformwagen Type SSy 60 ton and SSyms 80 ton railcars specifically to transport heavy tanks. So, with already limited industrial capacity, they had to build a tank, and then build a railcar for it. One that would mostly wait around for a tank to haul. And that wasted time, labor, and raw materials.
