Marlin 1892

I am chronicling this rifle primarily on the Marlin Owner's Forum because there seems to be very specific knowledge of this rifle there. But I do want to keep my friends here on The Firing Line updated. I'm using the copy/paste to keep this thread and a similar thread on The High Road updated.

starts out just like this one did (copy/paste) but continues on with specific pictures of specific parts. Fortunately I move very slowly and don't fit things until I truly understand what surfaces are involved. At least I think I understand.

I fitted the extractor in the old bolt but didn't want to finish fitting until I received brass/bullets and could complete the fitting of new parts while I fitted for function/cycling of the action. As it turns out, I was unable to make the old bolt function. It has a lot of wear on all surfaces and it seemed like I was chasing my tail. So I fit the new bolt to the existing finger lever. The bolt face seems to need no fitting. I received brass and bullets last Saturday and put together a dummy round so I could diagnose function of the feeding part of the cycle. So I had already replaced the bolt, ejector, extractor, and carrier pivot pin (it wouldn't stay in on its own) and now I have the new bolt fitted. But it still won't feed from the magazine all the way into the chamber. I have stared at the action for hours and tried to figure out how it works. I think I understand the sequence of operation now. First, I have to commend the designers of this rifle for its simplicity of operation. There are only three major parts involved in feeding a round from the magazine tube into the chamber. They are: Finger Lever (and extension), Carrier, and bolt. That's it. The early models didn't have a separate cartridge cut off and mine doesn't. So this one will probably never cycle the shorts and I'm OK with that. The finger lever extension provides all of the movement needed to feed a round into the chamber. It pulls the bolt back and lifts the carrier into position in front of the bolt so the bolt can push the round into the chamber. But to do this, the finger level has a couple of surfaces that interface with the hidden side of the carrier that appear to have some heavy wear. Fortunately Numrich has parts and some of them are NOS like the barrel was. The new bolt is NOS. That being said, I have ordered a new finger lever as well as a carrier toggle and finger lever pivot screw. In the end the only thing inside the receiver that will be original will be the carrier and the trigger/springs.

I am staying with the original 32 Colt Centerfire cartridge at least for now. I understand the conversion to 32 S&W Long is pretty easy but I prefer my firearms to be as original as possible. Though I must admit that the availability of the S&W cartridge is very appealing. The new parts have already shipped out and should be available for installation this coming weekend. I'm hoping to shoot this thing on Sunday. It should shoot well as it has a brand new barrel that is pristine.
 
Just wonderin' how the old 1892 is going. I couldn't see the pics on the Marlin Owners forum since I am not a member.
 
Progress is slow. I have all of the parts I need except for the repair of the magazine tube. That is turning out to be the hard part. Marlin's magazine tubes were different than everybody else's in that the outer tube is the one that moves up to expose the loading gate in the fixed inner tube. It relies on bending the metal at the end of the outer tube so the outer tube can pick up a pin on the follower and ride up with the outer tube. I spent the weekend trying to modify my existing outer tube but it was a failure.

I still don't have it feeding right yet either. I work on it every weekend but just haven't got to the point that it feeds reliably. I think I have it figured out, said that about 100 times before, but I really need the magazine tube to be working normally to assure myself that if it doesn't work it isn't related to how the rounds are fed into the receiver and onto the carrier.

I am still amazed at how few parts are needed to make a round feed into the rifle. The magazine is 4 pieces, inner tube, outer tube, follower and spring. In the receiver there is the carrier that has a rocker attached to it, the finger lever extension, and the bolt. The bolt has the extractor and the firing pin with the ejector pressed into the side of the receiver. That's it. in the receiver there are 3 moving parts. But what that means is that each part does more than one thing. Like the carrier. It not only lifts the cartridge into position but while it is doing that it is also holding the next cartridge in the magazine tube. I basically understand how the carrier/rocker/lever extension work together, but I can't actually see how the surfaces mate up due to the arrangement of the carrier on top of the lever extension. So I have spent hours just looking at how things fit together and try to figure out how they work together.
