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 […]

Master Cam video of machining the VG1-5

In this video we are showing the steps to do the first op on machining the upper receiver on the VG1-5 on the machining center.

We are getting closer every day to completing the VG1-5.

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. […]

AR-180b upper receiver

Here At Gun Lab we actually have a number of projects going on. While we are waiting for our heat treating to come back for the VG1-5 and AR-180b parts we started on the AR-180B upper receiver. This receiver is design to fit on the Nodak-Spud lower as well as the AR-180B lower and the […]

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 […]

OP 7 completed on the MP-44 trunnions

Op 7 has been completed. This is a major mill stone on making the MP-44 trunnions. The rest of the machining will be done on the manual mill. It will be easier on the manual mill then making the number of fixtures and tooling that would be required on the cnc machining center.

This is […]

More on the MP-44 trunnion

Operation 6 has been completed on the MP-44 trunnions. A couple of problems were noted. The first is the difference in length on the front of the trunnions and the second was the fit up of the locking shoulder.

This photo shows the difference in the lengths

You can see the corrected locking shoulder fit […]

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.
