In this video we machine a half octagon rifle barrel from a 1 3/8" blank for a .375 Ruger rifle we're building. We also machine a rear express sight base to fit the octagon portion of the barrel. We then show how to solder a rifle sight onto a barrel. Instagram: @mnrcustom

Watching this makes one appreciate the cost. That's a lot of machine work! Thanks for sharing.
I'm jealous. I'm out in the garage trying to take a barrel from 1" down to 13/16 with hand tools. LOL. I'll get there one year.
Brilliant craftsmanship
Hell of a craftsman. Thank you for the video.
Thank you
Beautiful. Thank you for the thorough text explanations!
Beautiful. My dream gun is a half octagon 1873.
I’ve read that octagon barrels were easier to manufacture in the 19th century but, with modern tooling, round barrels are by far easier to make today, and therefore cheaper. I don’t know if that is true, but I found the rational behind it interesting.
Beautiful barrel mate, I for one would be proud of that one. 👍
WOW,, outstanding !
Beautiful work wish it was for me.😊
nice work
Your work is gorgeous. Thanks for sharing.
Very cool

Sir , very very nice. Rifel making. Beutiful.
Devil's advocate: why not mill the blank with the milling vise offset by however many degrees, instead of turning down and profiling the blank? Beautiful work, regardless of how the result is achieved.
Turning takes off more material faster than trying to mill 8 different sides down to dimension.
Droolworthy!

Thats a work of art.

I once did a Douglas premium in half and half on an old 1885 hi wall 32-40. Darn thing stress relieved while machining (and I was using flood coolant) to the point it didn't shoot worth a darn. Wound up having to straighten it on an arbor press. I have cut a lot of barrels and most of them worked out well except for this one. Barrels can do weird things sometimes when you remove that much material.
I've experienced the same thing with a Douglas barrel as well. I've never had an issue with Krieger barrels though. I believe it has something to do with the cryo treatment they use

In Draw Filing hold the Tang in your Right Hand and push away from your body.... Observe the Chips.
Now still with the Tang in your Right Hand Pull towards your body..... Observe the Chips.

Хорошая работа.!
Yewww fresh vid!!
P.S. I could watch lathe videos all day, keep up the good work!
@@paulvenn4447 Thanks you!

Great work on this barrel, I’ve always wondered how these were made. I can’t imagine Winchester doing all these steps back in the day for production, but then again, labor was cheap in those days. How much does a lathe like that cost? Thanks for the video 👍🏻👍🏻
I just listened to that and got a bit nostalgic myself :) Thank you! Winchester would have had a more efficient method. Probably a horizontal mill that would cut on two sides of the barrel at one time. When I purchased the lathe I believe it was around $5k. I looked the other day and it's closer to $7k for the same model.
@@mnrcustomllc8253 awesome. Thanks for the info and reply. What brand and model is it?
@@JBrtn85 You bet! It's a Grizzly G0709
@@mnrcustomllc8253 great info thanks you man!
Would making a full Octagonal rifle barrel make the barrel more rigid and stronger?
damn fine work, sir.
Thank you!
I like your work a lot.
Thank you.
You are incredibly talented. May I ask what model/make of lathe and milling machine?
Love the compactness of this barrel , would love to see Finnishes product
I'll see if I can add it into the video when the rifle's finished
Have ever made a half octagon half round barrel for a Marlin 1894, say in 45 Colt?
Excellent workmanship, but wear some safety glass man! You won't be able to machine anything if you can't see.
Thank you. You're right, I should have worn safety glasses especially in the video. The reason I wasn't in this operation was because the tool was running at such a low RPM (around 200) that the chips were simply falling below the tool. It's no excuse though, and I'll make sure to have them on in future videos.
guitarsnguns I was thinking the same thing.
@@mikey87 This guys work is far too good to risk his vision, I really enjoy their videos.
Out of curiosity and after doing tons of electrical solder work, what type of solder are you using for this application?
A soft solder by Brownells called Hi Force 44. Flows at around 400 degrees
@@mnrcustomllc8253 Thank you!
greetings a question that steel you occupy is 4140T? or do you do the tempering?
I still have a Kropatschek that needs a new barrel.. Octagonal barrel.
How long of a milling machine do you have? I bet you need a really long one to get this sort of job done.
I thought about building a rig for the tool post, to fit a milling/ grinding tool. So every thing can be done on a lathe.
Your results look pretty good!
Greetings,
Jeff
Thank you! Sorry I didnt see this earlier. 52"
Beautifully done good sir. The design vibe is so Black Forrest. Will there be any inlay work on the barrel flats? Also, what caliber is this 7X57 Mauser maybe?
Thank you! No inlay work planned other than gold in the sight leafs. It's a .375 Ruger
@@mnrcustomllc8253 excellent, I like the .375 Ruger. One gets the bigger bang in a standard length non-belted casing. And perhaps the caliber engraved into the upper flat then gold inlayed?
@@ditzydoo4378 I like your thinking. We may go that route.
@@mnrcustomllc8253 thank you for saying so. I've often admired the elegant script engraving used on high British Bond street rifles. Tastefully appointed, not garish.
Looks great!! I was wondering what steel you use for the barrel.
Thank you! Chrome-Moly steel (4140)
@@mnrcustomllc8253 Thanks 👍
How do you remove all the excess solder from the barrel once the sight base is attached?
I use a sharp chisel to scrape off the big chunks (without touching the barrel) and then polish off what's left with 320 grit sandpaper.
@@mnrcustomllc8253 I really wanted to see that part =(
I have a Rossi M92 clone with a 24” half-and-half barrel. Why was this configuration done?
Any problems with stress relieving from the machining process? Wondering if the barrel remains 'straight' per se or develops a 'bow'
I've had problems in the past with different barrel makes, however I've been using Krieger barrels lately and they've worked very well for this type of work. I believe it has something to do with their cryo treatment of their barrels.
Why were barrels octagonal in the late 1800s? Did this shape provide any advantage during this time?
I'm not an expert on historical rifles, but from my understanding is they were easier to make by hand. The forging process created a somewhat octagon shape, and without a lathe it would have been easier to create the flats than turn it round.
Soft solder will hold sights on ok? I've always heard you had to use silver solder, unless I completely missed something here.
Yes, soft solder is all that's used on barrels. Silver solder certainly has more strength but the melt point is far too hot for a barrel.
I need a better lathe......
Why did you go with only a partial octagonal, if i may ask?
That's just what the customer ordered. I like full octagon's as well.
Did you go to yavapai college? Seeing many techniques I’ve learned from Alan haha.
Sure did!
MNR Custom LLC that’s awesome! You do great work. I appreciate your videos! Makes me want to build another 416 rigby haha!
@@RicksOutdoors Thanks Rick!
Who the hell disliked this video???
So cool. Are you going to remove the step where the octagon joins the round?
My Simson is so cool with full length rib.
Wish you great success in making such barrels
Thank you! I know I answered on AR, but yes the step will remain. Just the design we were going for.
Заебись
What I don’t understand is that you were careful to not over heat barrel when machining then you then you later heat it up glowing red with the blow torch? Why?. Also do you buy them with the barrel already bored? What material are they?
The reason you don't want to heat up the barrel during machining is to avoid warping it. Glowing red? That happens at around 900 degrees. The solder used was low temp that melts at 475 degrees which won't harm the barrel. Yes, the barrel is already bored and rifled. This one was chrome moly (4140).
My eyes must have fooled me because it looked like it had a red hint to it. Thanks for the reply👍🏻
Ganz OK, nur Löten muss er noch üben!!
ㄒㄒㄒ.台語經常是國語不同的文字拼湊.女人說黑寡婦蜘蛛交配後.吃掉她老公.而男人說不能讓黑寡婦蜘蛛的女苗有機會長大.這是男尊女卑的主因.那麼男女適合結婚同居嗎?許多人都知道.柑橘柚子的表皮油脂.能溶解保麗龍.被稱為絲耗.{台語經常是國語不同的文字拼湊.} .而在人體有阻塞溶解時.會有瞬間的愉悅感及止痛效果.也因此柑橘柚子的皮.與阿斯匹靈的原料相似.常被作為安眠止痛藥的原料.而泡酒稱為香檳老酒.有許多外國人說常在海面撿到成熟的柚子文旦及其他水果.而將損傷處切除.熬煮加工後.藥名稱為海落嬰.後來因來源交代不清.被送毒品罪..據說柚子文旦的皮也稱為麻黃素.製成藥劑後.有去除黑斑的效果.不曉得是否真實?我覺得毒品包裝.就像老欉的文旦.薄薄的果肉.很貴.甚至懷疑毒品會不會是用老欉文旦製造的?早期公務員說.糧食價格上漲.所以要求加薪.那麼糧食價格下跌.公務員是否應該調降薪資呢?
What are you up to?
you sped it up too much and it's hard to read the text
Thank you for the critique. I'll keep that in mind on the next one.
