Update on the VG1-5, upper receiver

We have been working on the VG1-5 at a steady pace to try and finish this project. This last week has been spent on the upper receiver. The lathe work has been completed on the upper and now we have started on the operations that have to take place in the machining center. This video […]

Interesting AR-18 tool

It is not often that most people think how something was done in the “Old Days” but I do. Lots of times you can not reproduce a part using modern machinery with a great deal of work. The “Old Days” I am talking about is not the 1600,1700, 1800, but the middle 1900’s. I just […]

VG1-5 update on the bolts

We bought this tool from Shars to allow use to hole the jaws in proper position the cut the proper diameter in the jaws for the bolt.

 

Once set up the bolts were turned and we were off performing op 1 on the bolts.

The first op turned the minor diameter of the […]

More on the VG1-5

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. […]

Older gun making video part2

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 […]

Weekend update and the fun of machining

Nothing really exciting to report. I spent the weekend machining large pieces of metal into smaller pieces. We have shipped the test MP-44 trunnions to Pete and while we are waiting for his report back we are filling our time working on making stamping dies. In this case all the pieces are sized and we […]

MP-44 trunnions finish op 6

We have finished operation 6 on the MP-44 trunnions. The reason that we started with 6 samples was to insure that we would have correct samples when we finished. Two of the trunnions ended up out of spec after we finished this operation. The drawings and cam programing were changed to correct and problems. These […]

Continuing the MP-44 trunnion

We have just completed the first operation 6 on the trunnion. It has also pointed out a few minor differences. When we started this project all we had was an original trunnion in very bad condition and a collection of out of spec drawings with incorrect dimensions.

Later a trunnion in very good […]

MP-44 Trunnions up date

We have now finished the first six test pieces up to the 5th operation. This next week we will complete op’s 6 and 7 and send them for verification for proper fit.

With the first 5 operations completed we will be starting on op6 soon. This is a master cam simulation of the process.

MP-44 trunnion part 2

The next machining operation has been completed on the trunnion. This is one of the many unexpected problems with reverse engineering a component. The magazine did not fit. An error occurred that was missed. It is a good thing to check after every step which we do.

You can see the differences here and it […]
