THE MOST SECRET AND HIGH TECHNOLOGY MACHINE OF ITS DAY. THIS MACHINE AND OTHERS CONNECTED TO IT MADE THE NORTH DEFEAT THE SOUTH AND FOR THE USA BEFORE INVENTING THE BUTTON RIFLING PROCESS BECOME A SUPER POWER.

Absolutely Marvelous

Incredible explanation/animation!

1:19 SEX TOP LEFT

There is a really primitive rifling machine at the John M Browning museum that he used. It was made from a log with rifling type notches cut on the outside of it and a steel rod with a cutter attached to the end. He just pushed and pulled the log back and forth with a handle and the cuts in the log made it twist. Pretty neat stuff.

Incredible! Just a bit confused that the bump stop advances on every stroke. I would think the bump stop would only advance once for every 360 degrees of revaluation of the barrel .

They also cold hammer forge them. Makes an incredible barrel. ruclips.net/video/oALJDh43K3I/видео.html

WE NEED TO BRING THIS MACHINES BACK TO THE US. It's unacceptable we've lost our manufacturing edge due to greed. Everything made in china is GARBAGE.

Thank you for your video it's really interesting I've always wondered how this was done especially years ago it's like a lost art to me

Would it be possible to get the cad files for this machine?

Very, very very interesting this video. This is old mechanism.

Has anyone out there thaught about the fact that Pratt and Whitney made a copy of this very machine and that this design is still used today for cut rifling. What does that say about the intelligence of our fore fathers?

Extremely important! Machines must be created so that they can never ever be regulated by any gov. This is going to be my main goal from now on. I hope it is yours as well. My so-called gov. In Sweden tried to regulate the machines used in the manufacture of guns. And guess what. Seconds after writing this I found a way to make rifling an integral part of a lathe which can never be regulated.

We have one of those for production work and they are running it way, way too fast. The base is almost jumping off the floor. We used to have two but before we were making smaller parts and they were running them even faster. Must have cranked the motor to 75hz on a VFD or something. Only one made it through that contract alive.

This machine made the USA into the leading arms manufacturer in its day and was far ahead of its time in design. It also helped the North in civil war to beat the South. The south did however get hold of a number of these machines that the North tried to destroy to prevent them from falling into South hands. The design of this machine was so far advanced that it is still valid today as a cut rifling machine.

Una elegancia que buen trabajo

Mauser barer is the best

It is a Stuart Models 10D

amazing video, no audio needed, but shows you exactly in detail how the process is done.

Fantastic

I used to set the wickman multi spindle autos I had 7 in the shop and was awsome I loved them

I watched guys do this by hand at Williamsburg. They pulled and pushed a rod, the handles of which rode between guides that established the twist of each cut. They said the old octagonal barrels established the “indexing.” Cut one groove to satisfaction, lock the barrel into the vise on the next flat sides, and cut another groove. Octagons always have two flat (parallel) faces on opposing sides.

Another way is to push a button through, much simple but it has it's limits.

This is similar to how threads used to be cut for screws but not as complicated.

It should cut each groove with one depth until barrel has made one full turn and only then the depth of a cut should increase.

Anyone ever worked at the SKF bearing factory in Toronto on Acme Gridley multi spindle autos ?

So the the cutter is wedged deeper with every stroke, the barrel is indexed with every stroke and thus with every stroke a new groove is cut slightly deeper than the one before. How come all the grooves end up the same depth?

the state of art before cnc era... gret video !

very cool

were prob the last generation of set up men..Men now dont want to get full of oil and dont understand pershiable tooling

VERY cool mechanic i love it :) .....nice Regards from north Germany

Good mechine India

Good mechien

First 🇺🇸

could you do the same with cold forging machine for barrels

رائع جدا السهل الممتنع

If the sine bar had a curved shape, then the speed of rotation of the bullet could be increased along the barrel, which would have ballistic advantages. One could try for example a parabolic or exponential curve, in both cases starting with a zero slope. What do you think?

こうっやってライフリングを刻むんですね。 わかりやすい動画で良く理解できました。 ありがとう。

ingenious Those old geezers really knew their stuff

It's amazing how much simpler servos can make a mechanical machine lol

V nice....plz make a video how rifling done using mandrel....

This is a fascinating animation of how rifling used to be cut into firearm barrels providing the necessary twist for bullet stability.

will have to stop by and see this museum this spring. :D

Really an ingenious design for the time.

Good, is it possible to get the blueprints of this design? I am a fan of weapons and also a student of Inventor, the program with which these designs are made and I would like to be able to recreate the drawing. Thank you

Buenas, es posible conseguir los planos de este diseño? Soy un aficionado a las armas y también estudiante de Inventor, el programa con el que se hacen estos diseños y me gustaría poder recrear el dibujo. Gracias

Don't touch! Comedy channel, well at least you got that right. It's a MACHINE TOOL. Rough use for like 100+ years. Worried about the patrons getting oil on their hands?

Nice
