One of my tanks is a dedicated degreaser. I use a strong solution of Trisodium Phosphate (concrete cleaner) and water heated to just below boiling, maybe 180-190 degrees. If you want to pay three times as much for a brand name, buy the degreaser Brownell's calls "Dichro-Clean"- - -it's the same stuff! 10 minutes in that solution, then a dip in boiling water to rinse the degreaser off, and from that point on I use nitrile gloves to handle the parts.

See, all that hoo-ha and handling for 5-6 rusting/cardings is what got me thinking the Laurel Mountain stuff. I hate re-work. But the stuff gnoahh mentioned souns like it may be worth the trouble. Anyways I have time to agonize over it until I get that far. (Like agonizing on whether or not to have the action re-heat treated. smile )

It's not hard to do, but it is time consuming, and attention to detail is important.

Excellent info/supplies here:

I've used 2 or 3 solutions, Bob's work very well.

Sounds like a neat project. What's the story behind the single set trigger? Rare beasts on Mausers.

Back when me and my pardner did bluing we tried to gather up more than one or two guns to do at once.

It helps spread out the cost of the stuff needed to jet them looking good.

A good job can be done with cold bluing if the parts are heated up hot to the touch.

As for the barrels we used scotchbrite.

The fine stuff didn't scratch.

gnoahh, It's one Brownell's sold, by golly I don't recall if its the NECG they list now but it was supposed to be a very good normal trigger if you work with it. The set part appealed to me back when I was enamored with light triggers. The idea was my idea of the ultimate East River SD deer rifle. I've always liked the lines of a full stock so it's that with a Shilen (#3?) barrel in .270. 20" barrel which Mule Deer said should work. Got a nice stock from the previous incarnation of Richard's so plenty of meat to work with. Not spectacular but better than good. One thing I want to try is a nice checkered bubinga burl inlay under skeletonized butt plate and grip cap. And a styleized butterknife bolt handle, hate the looks of a ball and it's no use to me the way I work an action. That's where the project stopped. Welded on a chunk of steel and after a lot of grinding I'm not satisfied so when it starts again cut it off and try again. Brownell's had a simple but classy checkering pattern with just a hint of carving which I think I can track down that really appealed to me. And of course it would require a pretty rust blue.

Sorta classic the way I would've liked it to be. Would like to try that in black powder. There was a Pennsylvania school, the name escapes me, that focused on the lines of the wood and steel working together rather than sticking furniture all over the place. Would like to try that too. Which would be equally non-typical because I'd want a plains caliber.

Sounds a treat. Full stocks are a challenge to get "right". Rule of thumb: whittle it down until it looks right, sleep on it, then whittle a bunch more. So many well meaning guys neglect the fact that you gotta have a slight reverse camber in the profile from the forward action screw to the end cap, but I bet you knew that. So many I see today look like 2x4's. Butterknife handles are tricky too, but I'm of no use there as I've never done one, but I do agree that when done right are efficient and classy in their own way.

I think you'll find that all the "schools" of Pennsylvania long rifle architecture focused on the lines of wood and steel working together first, and embellishment came second. Sometimes all that furniture* (inlays, patch boxes, and such) does draw the eye away from the basic form. My family heirloom Nicholas Beyer rifle is a plain "working rifle" devoid of any inlays and sports no carving that doesn't support the lines of the stock. (In fact, on top of its plainness, it's a "smooth rifle" also- no rifling. A fact of life among practical frontier rifles was that a tightly fitting patched round ball out of a smoothbore possesses near-rifle like accuracy out to 50 yards or so, and the smoothbore handles shot charges for small game way better than a rifled bore does. Very practical, and very common on what was the frontier in the late 18th-early 19th centuries.) The gun's plainness is an elegance all its own due to its well thought out lines.

* I can't help it- so many mis-informed people these days call the stock "furniture", when in truth furniture is the stuff attached to a stock.

Good conversation fellas, lots of good info. Might have to find me a classic Mauser project once completed with this winters Hawken project.

The wood will be a challenge. at least with the bolt handle you can start over/ One trick I plan on trying is building in a carbon fiber box beam to hold things straight. Just how I'm not sure, several optinns. Right now carbon bow laminations and spray urethane foam for the core are in the lead. Should be able to keep it all one piece with no warping worries.

Could be the execution of pictures of pieces I've seen but few inlays to disturb the beauty of the wood and almost no carving. The carving there is has that it grew there look. "The gun's plainness is an elegance all its own due to its well thought out lines." That's where my eye takes me along with good wood. I cannot do that and perhaps never will get the flow between wood and steel just right.

I may see if I can find a blueing class where they teach it..


I don't think I've ever heard of a community college or any similar facility that has a gunsmithing class. How about hitting a gun show or a pawn shop and picking up a beater gun from the bargain tack to practice on? The book by John Traister- - - -"Gunsmithing At Home- - - -Lock Stock And Barrel" has a good bit of information on metal polishing. One that's out of print but still available on the used book market is "Do It Yourself Gunsmithing" by Jim Carmichael. Both of those books were very useful back when I wanted a custom rifle, couldn't afford one, and had to teach myself to do it.

One final tip- - - -rookie metal polishers have a habit of rounding off corners and polishing away stamped lettering. Only do what's necessary to get a good smooth finish and remove all the old bluing- - - -a too-aggressive polishing job is very obvious to somebody who has been doing bluing for a while, and it can really devalue an heirloom gun.

Sounds interesting. I've toyed with the idea also of mortising in a carbon fiber tube or rod also, but never got around to it. Do keep us posted!

The thing is, Mother Nature is a b*tch, and if she wants to warp a fore end she'll do it. There's a lot of force exerted by wood when it warps and a simple structural reinforcement like this may not be sufficient to overcome it. I don't know. I think Art, Sitka Deer, has some thoughts on that.

Yes, Co School of Trades is still around. Though, I believe it is a Technical School rather than a JC or Community College.

Art likes to embed pieces of broken fishing rods, which is good. But with a box beam I think you can design beam with less flex for size using composite techniques. For bows you can buy unidirectional prepreg carbon layups which solve a lot of problems right there. Then band saw to a taper that will maximize structural soundness while fitting curvey wood. Build a U channel, fill with spray urethane and add a top for a composite box beam.

Of course you need a good piece of wood to start with, it's not nice to fool Mother Nature. Fixed a .410 stock with a true firewood stock. Wood in the butt stock had warped with such strength that a sizable piece of it had popped out of the stock. Relieved stress as best I could, forced it together, and epoxied it. No idea of how long it held. Belonged to an older woman, that was her gun when she hunted with her father. Hopefully it lasted 'til she died.

On the other hand I've mused about hollowing out a stock to laminate thickness and building an internal composite stock. Certainly would solve pretty wood/stability issuers. smile

The engineering part is fun, The artsy part, getting al the lines right for that organic look, scares me. I think that's what fascinates me. A chamber holding 50 kpsi plus right next to a trigger that would impress a watchmaker. All in a package that well represents an architectural period all to the admiration of art aficionados. Wish - dream - that I could do it all.

Oh, on decorations. Used to spend time in the Smithsonian before I got into black Powder. But what impressed me most was all the shiny crap people added to guns. Particularly trade guns. About 5 pounds of brass tacks in one trade rifle. So anything you make is authentic in one sense or another. laugh

The second was the collection of old uniforms, dating back to pre-revolutionaty days. We are giants by comparison.
