I think it looks good. Have you picked it up fromt eh FFL yet? Is this a collector or is it something you're going to shoot? What caliber?

Fred

Hey, that looks pretty sharp. A little felt tipped "anodize pen" would be a finishing touch.

Hope you like it.

Fred

So I made a couple of these picatinny bases for our Model 8 or 81 autoloading rifles. It should be a reversible modification primarily for the addition of a red-dot or reflex sight. You should be able to use your factory nut-plate and rear sight screws to install it. I'm asking $40 shipped (lower 48...

Fred

occasionally the bolt will cam itself 90° while it is being cycled by hand and once after firing, I have to push it into place with a tool so it is straight up and down. In my M81 examples the spring surrounding the firing pin will keep the bolt extended with the lugs at the 12 and 6 o'clock positi...

Fred

If you can't find one, send me a PM and I could probably make you one. If you want an original I could probably sell you my original and I'll re-make the one for my M81 that's been drilled and tapped for a scope and seen better days in general.

Fred

Slitter saw showed today, so I made an arbor and finished my screws: https://i.postimg.cc/DZDQfGx5/Finshed-Screws.jpg I'll order some material and make half a dozen little Picatinny adapters for the rear sight hardware. I'll post up in the for sale forum in a few weeks. *edit* here's the for sale th...

Fred

I know I'm deviating somewhat from my own thread topic but I could make a few aluminum "universal" picatinny red dot bases for the forum members if there were interest. I don't have anodize or Cerakote at my disposal so there'd be an extra step somewhere to make it a uniform color. Judicio...

Fred

Made some progress today.

I've been playing with titanium lately. If they're going to be $14 a pair, there's going to be a reason for it. haha. I'll cut them to length, chamfer and slot the heads when the slitter saw comes.

Fred

That's the plan. Add another nut plate for a pair of bases and mount something out front. To be honest, my M81's accuracy is so poor, the red dot at 50 yards is probably good enough. Optics would just make the shotgun pattern more visible and disappointing. http://thegreatmodel8.remingtonsociety.com...

Fred

Without a database of what was an actual D-grade Remington (serial number or other distinguishing mark), how would you know if it was or not? Did the Remington shop ever do customer work at request? If someone asked for that style of checkering and engraving would Remington have done work to the cus...

Fred

The reflex sight was me in 2014. It was a quick and dirty modified weaver rail to try and eliminate the other sight systems as culprit for poor accuracy, and now I'm looking to do it right on a replacement barrel/jacket. I have a drilled-and-tapped receiver already and the offset scope is the worst ...

Fred

Thanks for further evidence, Phyrbird. I believe I'll be remanufacturing the barrel jacket where I'll add another nut-plate to secure some bases for an extended eye relief scope or a red dot, low to the bore centerline (I was never very good with iron sights).

Fred

Thank you for the reply. I disassembled the gun and a 6-40 does fit in the rear sight nut-plate, but a new screw is pretty loose. An 8-40's too big and no matter how I try a precision ground 40TPI Brown and Sharpe thread pitch gauge does not want to fit the existing screws. No oddball metric pitch s...

Fred

The screws holding on the rear sight on my M81 are all buggered up. I want to try to remanufacture them, but they're in poor condition to be used as templates. Near as I can figure is that they're close to a #6-42. The major thread diameter's .138". They're definitely not 40s and with my calipe...

Fred

Like said above, stack the spring with the un-riveted ends towards the rear of the magazine to reassemble.

Fred

What Ideal mould number did you use? What diameter did you use, what OAL and what lubrication? With optics I haven't had much luck with jacketed or cast so if there's a magic bullet, I'm all ears.

Fred

There's no such thing as a free lunch. That said, Photobucket is crap. There's a variety of other "free" image hosting services that don't butcher/ransom images or apply some unwelcome watermark. I generally use postimage.org. Seems easy enough to use and the image hosting is relaible enou...

Fred

You can try annealing the New Grafs brass before you load. If that doesn't eliminate the issue I'd seek a solution through Grafs.

Fred

A replacement barrel is easy to come by, though likely expensive. Talk to any barrel maker to make to a coutour/caliber/twist identical to what you have, then have a smith thread, chamber and crown the replacement barrel. This is common work that should be a service available through any competent g...

Fred

Welcome aboard, Jean. Importing and exporting firearms-related parts is tricky as the parts may fall under the International Traffic in Arms Regulations (ITAR) umbrella. I believe that I cannot mail you a basic Model 8 wood fore-end or simple butt-plate without facing felony charges for exporing fir...

Fred

36" is a foot longer than it needs to be for a M8 rifle broken in two. I'd look at alternatives, maybe custom, or get a case long enough to keep from having to take the rifle down.

Fred

Here are 5 different 35 rem rounds from two different barrel/bolt combinations in an M81. These are factory 200gr core-locts so probably pretty mild on the pressure. I bet the headspacing's a bit different between the barrels. You can see that the ones in the rear have proud primers after firing, li...

Fred

I never had any issue swapping the bolt/carrier. You can see down inside the action some with the safety disengaged. You can try installing the bolt/carrier with the receiver pointed at the ceiling. The linkage will just hang straight down and fit like it should. Spring pressure on the bolt is the s...

Fred

With the barrel removed and the bolt all the way back (and the hammer cocked) you can hold onto the bolt handle and depress the magazine stop/bolt release catch. This will release the bolt/carrier. You should be careful of letting it fly without the barrel installed as the handle will likely ding th...

Fred

I'm not sure .358" was big enough.

In my area I see grey foxes, never have seen any red ones. I've never shot a fox though as I think they fall under another flavor of license for fur-bearing animals.

Good shooting and thanks for sharing!

Fred

My M81 cam pins are .561" ±.001 long, they ride the firing pin spring's OD in the middle of the bolt. You can also see where they tested the hardness of the cam pins: there are two tiny dings in the OD of each of the pins. If your .459 pins are not hard (test if a file scratches one end) then t...

Fred

I have a M81 bolt at home on a desk right now. I can get some pin lengths tonight for comparison.

Fred

Sounds nice, I'm looking forward to seeing some pictures.

Fred

FWIW my 1947 Model 81 in .35 Rem holds 5 down in the mag no problem... just not with the bolt closed. Perhaps the "4+1" designation is more accurate. I gather the intent was to use a 5-round stripper clip to stuff the magazine full then the bolt release would then strip the top round off t...

Fred

Maybe try some needle nosed pliers with a little cardboard to grab the pin and give 'er a tug?

Otherwise, ya, beg/borrow/steal a spanner to disassemble the retention pin/spring.

Fred

I don't bookmark things, I guess I'm an odd person. I can't remember the forum URL so I generally use a web search that gets me here. That said, once I've got all my browser tabs set up the way I like them I just refresh the "active topic" link to see what's going on.

Fred

So, how's it shoot?

Fred

I'd have a tool like this one made out of a grade-8 nut and use heat plus an impact wrench on the bushing to free it up. If all else fails, then anyone with a lathe can cut the bushing out instead.

Fred

Well as long as they keep it between 2.5TPI and 72TPI (and some metric options) I can accommodate them, regardless of their insanity. As an anecdote, I worked in an aerospace prototype machine shop for 7 years and have handled parts that are currently on Mars. I worked with things between 00-90s and...

Fred

It's possible that someone altered a 60+ year old rifle to be something other than factory too. I have been frustrated in the past that the industry that established interchangeable parts has so many oddball and otherwise non-stardard fasteners/hardware. In fact I've gone out of my way to make some ...

Fred

I just wanted to say that my M81 fore-arm screw is not an #8-32. My ~1945 M81 screw is a #12-28. Friggin' oddball.

Fred

I meant the barrel assembly. Other than the potential headspace issue you should be able to swap interchangeably between 35 Rem and 300 Savage in the Model 81.

Fred

Based on my experience with my 35 Rem M81 I can't see why you would not be able to swap barrels to a 300 savage with your existing rifle. The springs and bushings in the barrel jacket are the same as far as I've seen. The headspacing might be slightly different but it'd be easy enough to check. If y...

Fred

This is not my advertisement, I do not know who this is nor have I done business with this person, that having been said he's got 500 new .30 Remington Brass for sale "from Grafs" for $78 shipped per 100. Figured people looking for hard-to find consumables would benefit. http://castboolits...

Fred

About any job shop should be able to cut a steel stub to fit the barrel nut threads snugly, then cut some flutes in the stub allowing for debris someplace to go to. Should be good enough to clean out existing threads. One would think that that sort of work would be fairly inexpensive to complete. It...

Fred

I measured my M81 35Rem barrel at Ø.600-24 for the nut. You'd do better with a lathe I think. Custom taps/dies are not inexpensive.

Fred

Email sent.

I'd rather have tools/material than cash.
Do not send me any firearm receivers!
I have a model 81 I can use as a template for most parts.

Fred

Glad to hear it.

Fred

If you come up short, I can try to make you one on my lathe if you're interested. I'll use my M81's forend screw as a template.

Fred

Hey Everyone. I would like to get the parts arranged so that I can proceed with making a 35 Rem carbine barrel. I can find parts onesey-twosey but I don't want to have to pay triple shipping. So I'm looking for a 35 Rem barrel, buffer spring and recoil spring for a reasonable price, so I can get sta...

Fred

I am aware that the 81 is chambered in 300 Savage and that today the 300Sav is loaded to a higher pressure than 35Rem despite a .020" larger case head making for more bolt thrust than what would be experienced with the .35 at the same pressures. Yes, with hand loading you can exceed the SAAMI s...

Fred

I chronied a 215gr paper patched cast air-cooled clip-on wheel weight projectile at 2150fps from my M8 with 44gr of H414. The powder was settled (tapped) and just level with the base of the neck inside the case. Cartridge overall length was close to 2.550" It gives a good shoulder massage. I wo...

Fred

I don't think the loss of case capacity is the concern with the thick brass. I think it's a pressure problem for a given load. The difference in capacity is something you could actually measure if you already had some factory 35 brass for comparison, but it's more practical to reduce the book loads ...

Fred

I've been working overseas for several months. I was not allowed to bring my guns along so I've got nothing to contribute. I still read a few posts whenever I have time. Whenever I get back home I intend to figure out how to get my .35 M8 to shoot better than pie plate at 25yds. :cry: I'm interested...

Fred

I think the 300Sav and the 35Rem share the same magazine and follower, if not someone correct me.

That said, I had reasonable success using 2.550" in my 35 Rem. Bullet nose profile made quite a bit of difference in feeding reliability.
