Argentino M1879 Rolling Block. Is it worth restoring?

[Patrick Chadwick]

I have access to an ultrasonic cleaner at work so all of the small parts will get a follow up wash.

Great news! Do repeat electrolytic/ultrasonic runs on the backsight assembly until you get it free.

Hmm, now what to use for a barrel tank?

Use PVC plastic guttering, with end pieces glued on. It won't break the bank, and you can store it out in the yard.

Also you had asked for more pictures of the end of the barrel. I assume you wanted to see the condition of the crown. Let me know if these pictures don’t show what you wanted to see.

Thanks Joel, they are just what we need.
....Er, how shall I put this?....they DO show what I DIDN'T want to see: a blunderbuss muzzle.
OK, I had that on The Mahdi as well. Worse, in fact. Can be improved, if not 100% fixed.

BTW, I do not like the look of the barrel channel. Whatever that white stuff is, you need to mechanically remove as much of it and the rust a.s.a.p. Hold it upright and give it a good scrubbing with an old toothbrush so that it falls out of the channel - maybe you can make a guess as to what it is.

Do NOT (it's those capitals again!) use any liquid on the wood at the moment! And especially NO water - that will carry the rust and white whatever so deeply into the wood that you will never get it out!

But in anticipation of what is to come, I think you need to get
1 pint can of acetone
1 of that jelly-like paint stripper that contains xylol, toluol, benzyl alcohol and heaven knows what. The stuff that, if you get it on your skin, feels pleasantly cool for a couple of seconds and then burns like hell!
1 methylated spirits.
2 rolls of paper towelling
You will need a natural-bristle brush to apply the paint stripper (plastic bristles will dissolve), fresh air,
and
A PAIR OF CHEMICALLY RESISTANT GLOVES

I don't think I can get Part 4 done today. So in the meantime, keep up the good cleaning work!

"And don't forget in, folks, tune in to the same channel for Part 4 of our series, when the true identity of The Mahdi will be revealed, telling how our intrepid adventurer dealt with the dastardly Oriental challenge!"

...Oh, I forgot ...get a few old 3.5" diskettes as well.

I am not kidding

Huh????

Is there a less aggressive alternative to paint stripper? That stuff is so nasty. I’ve read that it can break down wood fibers on old stocks. If I have time, I’ll try to search up some alternatives and get your opinion.

Thanks, Joel.

P. S. Mahdi Link Please.

[Patrick Chadwick]

P. S. Mahdi Link Please.

Nope. It's a surprise

Huh????

It's another surprise

Is there a less aggressive alternative to paint stripper?

We will only use that if we have to. Ask around for alternative suggestions. But you will need the acetone.

It will all become clear in Part 4

[Patrick Chadwick]

And get a can of NATURAL TURPENTINE. And a can of (preferably boiled ) linseed oil. Good DIY stores or paint suppliers will have these materials. Paint stripper is negotiable. These two items are not!

[killforfood]

Patrick,
I re-read what gave me concerns about using stripper and it seams my recollection is a bit off since they were warning about using oven cleaner as stripper.

When we get to the re-bluing of small parts stage, what’s your opinion on Hot Bluing?
I have the chemicals and the desire to give it a try. Is it an appropriate finish for small parts of this era?

[Patrick Chadwick]

Please wait one more day. The choice of materials will be explained. I have no experience with hot bluing, but the rifle that bothers me because it looks falsely new was hot blued by a professional. He did it well, but it just looks too new for a 100 year old rifle, although that is indeed how they were usually finished - the kind of "blue" that looks black, of course. And color case-hardening is NOT appropriate for military rifles.

Patrick,

Just a quick update before I turn in for the night.
I made good progress de-rusting all of the small parts tonight (sorry no pictures, too tired). Not wanting to drag parts back and forth to work for ultrasonic cleaning, I went ahead and bought a small ultrasonic cleaner. It worked like a champ and I’m happy to say that the rear sight is completely de-rusted and moving freely (in fact a little to freely). It will need to be tightened just a tad to hold position.
I short circuited my transformer and had to splice my alligator clips onto a new one. I was tired and in a hurry and inadvertently reversed the polarity. Fortunately I only had some hanger wires in the bath when I hooked it back up. You weren’t kidding about CAPITAL letter warnings. The damage to the hanger wires was almost instant. I’m so glad I didn’t have any gun parts in there.
I haven’t built the barrel de-rusting tank yet but I should be able to find some time this weekend.

My bed is calling......

Refurbishing an Argentine RB - Part 4
Bear with me if we make a temporary diversion from your rifle...

Did you ever see the film “Khartoum” with Charlton Heston playing the part of General Gordon, and Lawrence Olivier as the Mahdi? If you did, you will remember the scene where the expatriates are escaping on a Nile steamer. The Europeans are firing back with Martini-Henry rifles at the Mahdi’s followers on the river bank, who are blasting away at them with 1867 model Rolling Blocks....

Meet "The Mahdi"





Yes, this is indeed one of those Egyptian RBs. Take a look at the finish - a century of sand produces a "soft-line" styling!


This rifle has Been There.

As to the markings, I was grateful to Remington that they marked the number on the tang (as mentioned in a previous post), where not even Ali Bubba could rub it off.

The markings on the barrel are mostly Arabic numerals, as the rifle was repeatedly captured and re-marked somewhere in that ever-dangerous region on the fringes of Egypt, Ethiopia and the Sudan.




I can read the numbers, but I cannot decipher the text markings.



This one looks like "?azara", which would mean "reprove, rebuke, correct" but I am no Arabic expert, and it may be Amharic. I have also heard of a marking called "the Mahdi mark". Unfortunately I can find no trace of such a thing in that definitive work "Remington Rolling Block Military Rifles of the World" by George Layman, so maybe that is another myth.

If any Rolling Block experts are reading this, and can interpret the markings, I would be very pleased to hear what they have to say.

This was the first time that I bought a rifle for the sheer historical interest, in spite of its poor internal condition. Basically, I paid for an RCBS die set and got a free rifle and a dozen cartridge cases with it.

Now please take a look at the muzzle.



When purchased, the muzzle wear was worse than on the Argentine RB. It shot so badly that it couldn't hit the paper at 100 meters, and the few bullets that hit the paper at 50 meters were going through sideways.
In a word - wall-hanger.

Now look at the side-on view of the muzzle.



It is strongly rounded off. Originally, the muzzle was about 1/8" longer, and the rounding was so extreme and off-center that the end was not even square to the bore. No trace of rifling in the muzzle. In fact it looked more like a worn-out shotgun muzzle than a rifle. The foresight blade is a replacement (I kept the original - it had been sanded down to a stump)

And this pic illustrates what happens if you are not very careful in removing a barrel band



"Honest sarge, it wasn't me, it was that Ali Bubba!"

At that point I had to make a decision - and the point of this excursion is that you, too, will have to decide: Do you want a good-looking wallhanger or an every bit as pretty but functioning rifle. That will determine how we proceed with the barrel. "Shooter" means a serious bit of recrowning. If you choose that option, I can help you through that too - the proof is in the pics of The Mahdi.

Your decision may be easier to make when you see how the rest of the rifle turns out.
I therefore propose that, for the moment, we leave the barrel on one side, well-oiled to prevent further rusting, and turn our attention to the action components. Woodwork will follow in Part 5..

Action components
As you are now busy cleaning up the components, it is time to look at the results.
If you have not yet cleaned up the two action pins, you need to know that the cleaning will remove the markings you have made. The answer to this problem is to mark the pins by filing a tiny notch on the cylindrical surface at the right-hand end, no more than 1/16" long. In this position, the mark sits in the hole in the frame, so it is invisible after assembly and is also not subject to wear. The snag is, you will probably need a diamond file to make any mark at all - those pins have a very hard surface indeed.

The block assembly will have to be dismantled, so that you can clean the firing pin. A firing pin sticking in the block is one cause of uncertain ignition!

As I already wrote, springs should not be electrolytically cleaned. Any hard rust should be scraped off, and the spring then rubbed down on the rusty sections with grade 000 wire wool (i.e. the finest you can get) and then oiled. Springs are not visible after re-assembly, so they just need to be mechanically clean, and saved from further rusting.

When you have got everything, including the inside of the action, as clean as you can, then re-assemble the action with lightly oiled parts (without the mainspring) for a feasibility check.

1) Is anything binding? If so, back to cleaning! Check for hard muck or fragments caked onto the inside of the action body. If there is no obvious binding, then
2) Does everything move freely throughout the complete arc of the block and hammer? If so, then
3) Is anything too loose? This indicates excessive wear. That would be something that I could hardly evaluate at long range - it depends on exactly how much wear and where. If the action pins are seriously worn, it will not be possible to fix this with kitchen table/backyard methods. But the rolling block action is simple and tough. The Mahdi had no significant wear in the pins, and no loose sockets. Remarkable after a century of sand!
But what it did have was
4) A block that did not close properly, leaving a gap of about 1/4 mm at the bottom and 1/2 mm at the top. Although it would have been possible to fire the rifle, every case would have acquired a skewed base. And yes, it would not have been a good idea from the point of view of safety. To think that some people worry about a couple of thou in their headspace clearance!
Unlike a bolt-action rifle, this can also be fixed.

Depending on results, you may need to post pictures of any parts that appear to be dubious

Cleaning rod
If you look at your picture that shows the action from below, you will see a plate closing off the action towards the front, below the end of the barrel. This plate should have a threaded hole in it to take the screwed end of the cleaning rod. It will probaby be a wierd thread, and the metal may be glass-hard, so that recutting it is a problem. Take the opportunity to measure it now - it will, be a bit of "see what fits" trial and error, I'm afraid, as it is probably no longer a clean thread - before the rifle is completed and re-assembled.

If anyone knows what the thread is supposed to be, please tell us!

You need to know the thread size (i.e. what is a practical fit) as the chances are that a replacement rod is
a) impossible to find
b) if found, excruciatingly expensive
c) the thread does not fit and finally
d) annoyed by a) b) and c), you decide to make a replacement.

If the test fitting of the action components is OK, then you have a potential shooter. If not, then post details - as you have to evaluate any defects in conjunction with the barrel condition to make that fateful shooter/wallhanger decision.

You are now going to have to face up to another decision: What kind of finish to apply to the metal. The condition of the rifle is such that there is no original finish to be preserved. So you have a free hand - it is your rifle - it is your decision. However, as always, I will offer a few thoughts for consideration.
1) Hot-bluing (but for a black surface, not actually blue).
As I mentioned, with regard to "one I did earlier", hot bluing can look very, very good. Unfortunately it can also look too good, and in combination with wood that is undeniably old, can give a "mutton dressed as lamb" effect.
2) "Struck bright" as the N-S skirmishers would say.
No finish, but everything polished. Then it would look like The Mahdi.
3) Cold blued.
This is the method I prefer, as with a little practice you can tone the result to look less crassly new, more like an original finish would look today - if it had not rusted.

Let me know how you feel about this before I continue.

That is enough for today


End of Part 4

[killforfood]

Just a quick update,
I’ve completed the de-rusting of all small parts. Yesterday I cobbled together a tank large enough to de-rust the barrel and it’s done as well. Don’t waste your time with those small wall transformers that I’ve been using. I burned up three in short order.
The fit up and function of the action went well.

Sorry out of time for now. I’ll work on getting a nice big wordy and full of pictures post soon.

Joel.
