I am looking for an article that was written in 1946. The title is “German Mass Production Methods: The use of stamped components in gun manufacture” It was written by Charles E. Balleisen and published in Army Ordnance September-October 1946.
Thank you for your help
The last two video’s showed spot welding and the first op machining for the VG1-5 lower receiver. With this video we are installing the magazine housing into the receiver. Once again there is a certain amount of hand fitting.
A close up of the fixture.
The batch ready for the next step.
This video was taken at an Italian factory where they are working on Carcano’s and Revelli machine guns.
Just a great deal of hand work
You have seen the previous write posts about the cnc router. The table was not steady and had way to much movement. That was the first problem corrected. Now we are on the way to correct the wiring and control circuits. The wiring as we received in the machine looked like two rats mating and dropping by products everywhere.
So first Plexiglas was cut and routed out for fans and filters.
This was completed the old fashion way, by hand tools.
Then they were mounted on the frame.
The new mounting plate was laid out and hole were drilled and tapped.
This too was accomplished the old fashion way,a ruler ,straight edge and square.
The rest of the components should be here this next week and I can finish up the new wiring.
You have now seen the first series of spot welds necessary to put the strengthening plats in and putting then together. With this accomplished it is time to do the first machining op on the receiver. This operation cuts out the trigger opening and also the holes necessary to weld in the front barrel support. The magazine housing area is also machined out to the rough shape necessary to install it.
here are a few solid models of the fixture we used.
The individual components use in the VG1-5 lower receiver fixture.
This is the Master Cam simulation for machining the VG1-5 lower receiver for op1.
This video is showing the machining of the VG1-5 lower receiver op 1′
this is a picture of the part after machining but still in the fixture.
Axel is our friend and a friend of Gun Lab. When I mention that we had gotten our approval from ATFE and that we were starting the build production line he volunteered to come and help. And help he has done. He has been here for two weeks of work and looking and playing with toys from the reference collection and just generally good gun fun. He has been a huge help with getting to the next phase of this project. The amount of work he has done is not is beyond measure. He has performed every task that was asked of him and more. It is hard to believe how fast two weeks have gone by. I am sure he is looking forward to going home just to relax.
Another in the series of older gun making video’s. This is one on making the BAR.
Here at gun Lab what we do is study weapons and at any time you could come across anything. A set of EM-2 locking flaps,
a Destroyer carbine,
a Vickers cut away lock,
Hand drawn prints for a weapon
or a French MAS 36 22 trainer cartridge adapter.
Anything and everything can be found in my office area. So today we are going to be looking at a MP-44 half of a receiver. I enjoy studying parts and looking at this part it is very interesting to see how the Germans made this part and the interior design that you hardly ever get to see.
A couple of views of the back of the mag well housing and the added pressings.
A look at the front of the mag well and the added strengthening plate spot welded on.
A good view of the press work on the inside of the trunnion and magazine housing area.
The out side view. Nice trunnion curvature.
Look at the internal and external rib stampings
This is a nice photo of the magazine housing ribs.
Look at the transition between the receiver body and the trunnion.
As complex as this weapon is I am amazed at the quality of the stamping. This is actually a beautiful stamping
Today’s post is another of the video’s out there dealing with making the weapons of war in the U.S. This video deals with making the BAR and it.s magazine.
What is interesting is the pressing dies and method used to make the BAR magazine. I find the fixture design to answer question that I have on how to fixture something.
Enjoy the video
