I hope your surgery goes well, but I suspect you’ll find a way to read the forum, too.

Well, I'm in kind of a bandwidth problem here. My ISP whose initials are Century Link crapped out and they screwed up a service call and several chats with them.

Thus I am operating WI FI through a kind neighbor lady's router, with her permission. Only three bars signal, she's 53 feet away, but it's enough for an occasional toe-dip to check e-mail, the weather, and THR. I do not want to abuse this privilege. Nope, no more porn or politically incorrect videos until CL gets off its tuchas and fixes my connection. Dang.

It's maddening when they direct you to their website to clear up a connection problem. Don't their site developers think? And too many of their dropdown choices are not appropriate to one's particular issue. Zip code? I went through that a couple of times before I realized they wanted my billing address zip code (a POB in Denver), not the zip code of my apartment house.

Dumb me.

My fluency in the German language never got very far at all. Started learning German at a very young age from my maternal German grandparents. Both born here to German immigrants and grew up bi-lingual in both German & English. They would converse in German when I was very young and wasn't supposed to know what they were talking about. When I began to catch on, they had to discuss that stuff when I wasn't within earshot.

My father told me that his father would not allow their native German language to be used in the house. My father (born 1901) imitated his father (my grandfather, if you have trouble following that) saying, with a heavy German accent: "Ve are Amerikanisher now and ve vill speak Anglishe vee ein Amerikan."

I wonder how you say that in Spanish.

It did, thanks.
Been up most of the night with a headache though.
Guess it's time for my pain med (not a big fan)

My wife got me a 8" tablet that is sooo much better than trying to read this on my phone!

Wishing you a speedy recovery.

What is the twist rate on that barrel?

Dammit, that's been bothering me.

Without doing detailed research, I figure you can do it with proportions from heavy 5.56 NATO rifling. Ought to "scale up" good enough for a guesstimate since spin RPM ought to be approximately similar for similarly shaped projectiles.

Figuring 1 in 7" twist for heavy, long NATO .223" bullets, we take the proportion
(88mm = 3.46")
3.46" ÷ .223" = 15 ish
So 15 ish X 7" twist = 108" twist for the 88.

108 ÷ 12 = 9 feet ish.

So the 88's twist ought to be about 9 feet, disregarding sectional densities, since the 88 projectile is filled with lightweight explosives, and the .223 projectile is filled with whatever the hell "green" (not radioactive, and not lead) substance they are loading .223 bullets with to make that rinky dinky tinky little light varmint windblown cartridge into the mighty old muscular .30-06.

So, if I were betting on the rifling of the 88, without looking it up, I'd say about one turn in 2.74 meters or 9.15 feet.

Ish.

At the muzzle if it's gain twist rifling.

Corrections and / or referenced real data welcome.

According to Wikipedia (so take that for what it's worth) it does have a gain twist rifling.

32 right hand grooves, 1:45 to 1:30 twist.

 

[230RN]

If they mean 1x45 means one turn in 45 calibers, and if 1x30 means one turn in 30 calibers, then the starting twist is 1 turn in ~13 feet and the muzzle twist is one turn in 8.65 feet.
Compare to my rough guess of 9 feet. Not bad fer uh amicher, huh?

 

[Mk-211]

Good to hear everything went well, hopefully you heal fast.

Looking forward to seeing more of your creations!

 

[Poper]

Hoping your surgery is successful and you recover quickly. Thanks for posting those pictures! A hunting buddy has a crippled arm from having the breach on a 155 slam closed on it.

That hurts just thinking about it!

 

[hdbiker]

Good luck to you Y-T

This happened on a firebase in Vietnam. He never recovered full use of his arm but was able to work and retire from a job in the timber industry.

I'm guessing he was lucky they were able to save his arm.
Still, the visual image is one that makes my arm hurt!

That video I provided gave a glimpse of a guy manually shoving a round into the breech. I guess it was dumb luck that kept him from getting hurt.
See 1:00 minute and a few seconds following. Everyone else was shown almost throwing the round into the breech and keeping clear.

I note that he at least had enough of an understanding of the mechanism to keep his hand cupped with just the heal of his hand on the base of the projectile and his fingers very much held up completely out of the mechanism, so that the breech block (or whatever it's called, I'm making up my own term here) would act to push his hand out of the way instead of slicing parts of it off.

I had three surgeries (the first two being more conservative, but not being successful) on my left ear when I was 18 years old, to repair a blown eardrum. When the second was determined to have failed, I was brought in for what was called a "radical" tympanoplasty, during which the ear would be separated all along the rear from my head, held only by the front. I didn't wear glasses of any kind (only wear sunglasses today, 38 years later) but, yes, that was a long and uncomfortable scar, which I still have back there.

Your equilibrium is probably gonna be a bit off for a bit, too. Pretty much any work in the ear messes with that. Mine didn't get too bad. Probably would be worse now, being more up in years as I am.

 

[MedWheeler]

Kind of a funny addendum to my post above (#40.) The injury was a result of a street mugging during which I took one or more blows across that ear. Later that afternoon, I told my mother my ear was aching and she took me to a walk-in clinic, what we used to call a "doc-in-the-box" when such clinics were just becoming a thing. The doctor there looked in my ear and told me that he saw "a bit of blood on the eardrum." He then referred me to an ENT practitioner, who I saw a few days later.
That doctor looked in my ear and told me "Well, the three inner ear bones all look good. Nothing wrong with them."

"That's good, right?" I responded.

"No, that's bad." He answered. "I shouldn't be able to see them. There should be an eardrum in the way!"

Yeah, same here: tympanoplasty mastoidectomy.

Cut my ear off along the back, taped it to my face then drilled out all the diseased air pockets in my mastoid bone.
Went into my middle ear and removed what was left of my anvil, hammer and stirrup as they had been "destroyed" (doctors words, not mine) from what were yearly ear infections.

Equilibrium is all messed up (but, in an unrelated issue other doctors found lesions on my brain after a bout with optic neuritis and they think I have the beginning stages of MS so that might be part of my equilibrium problem too)

Dr said next infection could break through my brain pain, infection spreading to my brain and kill me.

Facial nerve is now no longer encased in skull bone, feels like a 9 volt battery is on the right side of my tongue all the time.

But, hey, there's a million people out there who got it worse than me!!

 

[MedWheeler]

Incidentally (post 40/41), I had a date with the Army on 29 August of that year (1984.) The injury occurred on D-Day, two and a half months earlier. The first two attempts to correct it took place before my report date. The third, the radical one, was scheduled for 31 August, with the doctor understanding that I might not show up.

At MEPS on the 29th, the Army doc found out about all of this and kicked me out.

Sorry to hear about your army experience getting cut.

Ain't we a couple of beat up old farts!

I was going in for MP, to pursue civilian law enforcement when I got out. I still got to do that for a few years before crossing over into EMS, where I remain today.

Preach.

my dad's best friend got hit by an 88 a few steps onto the beach at normandy, not that far away from him.

i don't know what beach. getting anything out of him about the war was damn near impossible.
