ADD NOTE April 19 2017:
Because of complaints on the difficulty of printing photos and drawings, all of the photos have been moved to Flickr, which better supports downloading and printing. Fell free to use what you need for your personal work. Some day I'll put all of this and my notes all into a book form, but I'm pretty lazy so don't get your hopes up, I'll probably die first!


When I do barrel work I make and keep mechanical drawings and later when I quote a job I will refer to them as a reminder of how much work is involved and any notes I have made that pertain to the job. I also make a photo copy and when I do my measurements of the action I will strike out original measurements on the drawing and put in any new measurements that don't match the drawing. Then I just peg them to the wall above the machines to refer to when I do the job. I have started putting them to files that I can just print off as the originals look like the pigs chewed em. These are a few of what I have redone so far. Just save them to disk and open them with PC Paint or any draw program and alter them as you see fit. Bare in mind that no two actions are exactly the same (except most Japanese made Weatherby Mark Vs) and new measurements must be taken for every job approached. But these are close enough for job costing and double checking your own measurements.

Feel free to add your own drawings of shanks and parts for others as you feel fit.

Thanks for the information. I have an old Remington 788 with a worn out barrel so it's nice to know a couple of other barrels have the same TPI and pitch.

I'm curious about the side comments on the Savage lock time though where it talks about slow locktimes as I've always been told that one of the advantages of the Savage is it's fast locktime.

Remington short action- 2.6 ms.
Savage short action- 1.65 ms.
Colt AR-15- 6.0 ms.

In the past the Savage short action and the Remington short action were quite close. Back when Otteson wrote his books he estimated them both at about 2-1/2 MS. The problem with the Savage has always been the resistance on the main sear due to it's bulk and drag. There are huge variations in lock time from one gun to the next. The Savage has gotten a bit faster with redesigning but not much. The 700 short action was tricked as well and the firing pin was fluted and the main spring changed which sped them up a lot. There are aftermarket kits available for both but the key to really speeding up the Savage will be in somehow removing the temperamental and heavy first sear that must get out of the way before the pin can fall.

I just got through re barreling a Martini Cadet to .218 Bee. Very time consuming !

Defiance Deviant

Gunsmith Rod Henrickson Defiance Deviant by Rod Henrickson, on Flickr

That's very organized of you!! I just write the dimensions on a notepad or on the wall behind the lathe. The notations on the wall get spattered with coolant and the grand daughter draws pictures in the notepad so I don't know which is best. Both locations have a limited lifespan.
By the way, regarding the Post -64 Model 70's, increasing the thread diameter, while perhaps not mandatory, is absolutely beneficial. This is especially true of the WSM chamberings and even standard magnums. The distortion of the chamber when the barrel ia torqued up tight is measurable on the fired case. One 300 WSM I looked at was oval by .006" when the barrel was tightened up yet the chamber was round when the barrel was removed. This is why Winchester changed the thread size on the Model 70's. A thread cut so there was interference on the major diameter might be supported well enough that distortion would not occur but for the WSM's, I re-threaded. Regards, Bill.

I've got those same notes Bill. Not only are mine so soaked with ridged cutting fluid that they look like the ink blots the crazy people drool on, but the numbers have been crossed out and redone so many times that there is no room left on the pages.

It wasn't so bad a few years back because I had all of the measurements committed to memory. But in the last decade or so all these fool kids have been pissing out new actions faster than I can memorize them. Becoming an Ole Peckerhead hasn't helped much either. While it's helped my disposition and turned me into a sweat, lovable sort of critter, it's done nothing for my memory.

As far as those short action magnums. I have quietly named them all "FAT BASTARDS". I guess I'm showing my age but I still have nightmares from when everyone was wildcatting the 284 to 35 caliber this and 40 degree shoulder that and all the problems that we had making them feed. It's a personal thing, but they could banish all of those short, fat, turds and I wouldn't loose a wink of sleep !

Sweet and lovable? You must hang out with the Grizzly bears up around Jasper.

Back to cases, my "Go To" rifle is a 300 H&H. A cartridge that feeds slicker than goose poop on the barn door steps.

I think it must have something to do with our eight month winters WoodHunter. Four months of poor sledding and skiing really tends to gnaw at you after a while!

Thanks for posting all of that!

I'll post more as I get them done. The nice thing about posting them in a few places is that they never get misplaced or destroyed. I have made hundreds of drawings over the years that took me hours of thinking and measuring for one silly part or another and in not referring to it for a couple of years they just vanish. This is a lot more permanent than the back of a cigarette pack. I don't care what Ole Leeper says, putors are actually good for a couple things outside of downloading porn, music and playing video games. Whoever would have thunked it, huh?

Thank you very much. I will look forward to it!

I just had another Winchester pre-64 which had the carrier tongues bent by people installing the carrier screws without having them lined up properly which crushes the tongues together. Most people just spring them apart with a screw driver but this generally leaves the tongues bowed in the middle and causes them to drag on the side of the receiver which makes the leaver stiff to operate. The proper way is to make a set of peening blocks and peen them back straight. I have used the same set of blocks since I did warranty for Winchester 20 years ago.

Most of the headache, danger and damage of glass bedding a rifle can be eliminated by making and using an action jack. It is just a simple device that wraps over the action and presses on the stock over a large area that pulls the action free using a screw in a bar run through the action. The jack is actually a lot more powerful than people think. If you forget to put release agent on the barreled action it will quite literally push the stock to pieces. I have actually pulled actions that people have forgot to coat with release by heating the barrel slowly until the bedding softens and then, very slowly and carefully, pulling the action a bit at a time over ten minutes or so with the jack. I don't know how many hundreds or possibly thousands of dollars in damage and time the jacks have saved me over the last 35 years. It's a must have for bedding.

Here is the photo of the basic jack. A monkey with a hand drill, file and a hacksaw can make one from channel aluminum. The video shows basic use.

Ole SpeerChucker, since your a Canadian this will be right up ally:

Is the CZ 550 the same as a Brno 600 that was imported to Canada in the 60s and 70s. Is it 1.1 x 12.7 like a large ring Mauser. Do you have a tenon drawing for both the CZ550 and CZ 550 Magnum.
Thanks Longshot

Weelllll now, I have never made a drawing for the Ceska Zbrojovka 550 because they are so simple and because of their little problem with uniformity. Off hand, I think the extension for the magnums and the standards are the same. The shank is indeed like a Mauser and just off the top of my head I think the shank length is about 1 inch but I'm not 100% sure and they are NEVER EVER the same anyway. You should first center drill a shaft and turn it between centers so that it just barely slides through the body of the action. Then dog the shaft off to the action and lightly re-cut the action face between centers. After you have a nice flat face to work from, take your depth mic and measure the action for the thread extension length.

The OD of the thread is simple. It is 28mm or 1.102 inches. The pitch on the other hand is a bit of a problem as it is 2mm. No problem if you have a bi-sexual, grenouille speaking machine, but a big problem if you don't as 2mm threads work out to 12.7 threads per inch or 0.07874 pitch. I know some Bubbas cut them to 13 TPI but it's not all that close and not good practice. If you happen to have an older Southbend, Boxford or the like machine with all of the original English gears you can use this calculator or any of the others to figure out your gearing to the closest pitch.

Nat,
Did you get your CZ550 action wrench figured out?

This thread is worth a STICKY !

. . . Bare in mind that no two actions are exactly the same (except most Japanese made Weatherby Mark Vs) and new measurements must be taken for every job approached. But these are close enough for job costing and double checking your own measurements.

My own experience of late is that the Rem 700's are getting worse. Early A, B, C and no prefix actions seemed pretty consistent as far as receiver threads. The last couple of SPS actions I've built off were horrendous. Major thread dia on a couple ranged from 1.0455" to 1.0590", a somewhat far cry from the 1.0625 one may have become accustomed to.

I have noticed that too. Back when I worked for them, everything was made on single stage machines and everything was pretty close tolerance. Like most other manufacturers they have gone to CNC for most of their production to cut costs and tolerance numbers seem to have broadened a bit. Just like the automotive industry, loctite and CNCs have become a necessary part of production.

Or it could be that I'm just an old peckerhead that thinks that everything was better when I was a kid. I have been accused of being grumpy and arrogant and where there is smoke, there is generally fire so it could just be that. LOL

My experience is opposite of yours. The late model CNC receivers are the straightest Remingtons that I have worked on.

Rod, We've been Buds for quite sometime and I know we won't always agree, but we are still friends.

It wouldn't be any fun if everyone agreed. Plus we would never have any advances in technology because we would all agree to do the same damned thing. That sounds boring even thinking about it! LOL

The last 4 "New" Remington "Factory"actions I have been sent had single lug engagement, and No primary extraction. Had to true up both the abutments and the lugs remove the bolt handles and move them forward .035".
Piss poor examples of quality control.

Butch: Think I have a plan for a Brownells style action wrench for the CZ 550 actions. I know I have the rear entry wrench figured out.
Nat Lambeth

I still say you should write a book, chucker...

Happy to see you are now somewhere I can read your posts!

PS. My offer to do all the illustrations for you still stands.

2 weeks before the start of bear season is probably the STUPIDEST time of year to put a new barrel on a rifle. But, being the only clown in these parts that works 7 days a week and can install a barrel in under a week I get a lot of this nonsense. As I always say: "I'm a whore and I will do anything for money." And as far as the stupid part, not my circus, not my monkeys, I just clean up the turds.
