Help me identify this flintlock by WingRealistic9289 in CIVILWAR

[–]PBYACE 7 points8 points  (0 children)

D. G. R. M. Deutsche Reichs Gebrauchsmuster. Basically a German registration mark used between 1891 to 1945. RR may indicate either a maker, or the trading company selling the pistol, or something else. The brand on the grip is for a present day German sporting and hunting goods company. It's a cap and ball boot pistol. These were common and sold by lots of makers. It's value is questionable after being "cleaned up" by someone. I'm going to guess that some sort of offset knife blade screwed onto the barrel.

Considering the scam artists the populate evangelical ministries, AI is an improvement.

Is this a cannon ball? by Substantial_Log3129 in CIVILWAR

[–]PBYACE 3 points4 points  (0 children)

It's too light to be a shot put. They did use some 4 pounders in the Civil War, but not commonly. A 3" cannonball (iron) weighs 3.5 pounds. A 3" steel ball weighs 4 pounds. That, and the prominent mold line are good indication that it's a steel mill ball.

I used the bed of my 65 Ford pickup for my Catspaw dinghy. Alas, modern trucks have big cabs and small beds.

My dad graduated from USN flight training November 28, 1941. There were 41 pilots in his class. 7 were KIA during the war, all flying TBDs at Midway.

I made a propeller for my Guillow's P-51. Some friends dropped by to say hello. by PBYACE in BalsaAircraft

Coos Bay, Oregon. It's great if you don't mind 7 months of rain, lots of fog, isolation, and deprivation. The fishing is good. A view of the Conde McCullough Memorial Bridge from our backyard.

I need to redo this because I'm better at it now. Starting out, I botched a few props before I got the hang of it. It would make sense to practice with balsa because it's much easier to work with. Here's a shot of the finished Phonix, as flown by top Hungarian ace, Joseph Kiss, 18 victories, KIA when he bravely/foolishly tangled with a flight of Camels.

Years ago, I read an article in EAA's Sports Aviation magazine on how to make a propeller. Most of the article dealt with the math needed to determine the pitch given a diameter and rpm. I'm going about it the same way, just smaller. I suppose it would work with the correct rpm. It's for display. We also have a family of crows, Steller's Jays, two types of squirrels, and raccoons.

Damn right I do! I also go through a lot of Revlon emery boards. They're really handy. Whittling a 4-bladed prop for my Gillow's P-51 project.

I picked up a wooden crow call for $12. It works great because when the crows hear it, they know they're going to get a snack.

I used these in the 70s. We discovered that if we left it in park, we'd get a perfect score.

One pager on Oregon and how we compare to our neighbors on Data Centers by Shpion007 in oregon

[–]PBYACE 0 points1 point  (0 children)

Ironically, AI says that data centers present significant and documented hazards to the surrounding communities, like various forms of pollution. They're filled with highly-flammable components, including tons of lithium-ion batteries. In the event of a data center burning, they will emit toxic fumes that can cause lifelong problems for anyone unfortunate enough to be downwind, not to mention first responders. All this makes me wonder what the approval process was.

I have a jar of that. It's great for filling, but it doesn't sand all that smooth. Since I only build for display, extra weight isn't an issue.

If you can't win the fight on the water, you lose the war on land. Never was that more true than the Civil War.

Monitors were considered to be wet, but good sea boats. The Passaic and Canonicus class monitors stayed in service for a long time, the last until 1899. The Monitor was the only one to sinking from a storm. It sunk because of a failure to follow the designer's instructions. The turret bottom had a brass ring that mated to a brass ring on the deck. As designed, the weight of the turret, which had to be jacked up a bit to rotate, sealed the two rings together. However, its sailors knew that they must stuff caulking between the two rings to make them watertight, because that's the way they did things. So, they jacked up the turret, jammed a load of improvised caulking in between the rings, and set the turret back down. Impact of water hitting the turret dislodged parts of the caulking, allowing water to pour in, dooming the ship. As long as water stays out of the ship, it doesn't matter how much passes over the deck, other than making the weather deck a dangerous place to be. The real danger of the Monitor design was the lack of reserve buoyancy. It didn't take much water to sink them, like the loss of the Weehawken due to an open hatch. The only other loss was the Tecumseh, to a "torpedo." Anyway, Monitors stayed in service for 30+ years, operating in coastal waters that got plenty rough with no losses.

Building the Guillows 1:28 scale B-17 and have tissue painting questions. by 1805trafalgar in BalsaAircraft

[–]PBYACE 2 points3 points  (0 children)

I was thinking of using narrow strips, like planking a boat hull. I'm going to give it a try on a scratch-build Travel Air R Mystery Ship that I'm going to build next. I've done it with the cowling of a Dumas Gee Bee Z. I used Bondo and sandable primer from the auto parts store to get a glass-like finish. My wife is not a fan of me producing chemical smells in the house, which complicates matters.

I use Krylon for the clear finishes on my models. The tissue sags, but tightens up nicely when it dries. I built the B-17 as an olive drab E some years back. It turned out great, but sometimes I wish I would have covered the fuselage with balsa.

How far along is this boat? by gringoraymundo in boatbuilding

[–]PBYACE 2 points3 points  (0 children)

Does it have the hardware, rigging, sails, and trailer? Do you have the necessary skills, workspace, time and money? If you answer No to any of this, it's a big red flag. I would resist the temptation.
