We have started on Pete’s, a friend of gun lab, new 4140 MP-44 trunions. This series of videos and posts is the process we used to make them. First the video. Here are the pictures going over the changes and the steps we took. We needed to change the depth of cut for […] I came across this series of videos by accident. The project is not complete yet, but it is turning into a very nice piece of art. Check it out. Part one of the series.
Part 2 of the series. Part 2b of the series.
Part 3 of the series […] We have started with the first few operations on the VG1-5 barrel. When we started we were going to use the cnc lathe exclusively, but with the length of the barrel and no steady rest on the cnc lathe we had way to much chatter. So another change of plans was in order. The steps […] The last post on the bolt was when we completed the lathe work on it. This left us with a turned bolt with the firing pin hole drilled and bored. A fixture was designed to allow us to machine the bolt at the different angles and still keep everything aligned as it […] This post will go through the steps necessary to machine one of the lower receiver. I was going to do a video, but there was not much to see with the coolant on. If you remember the last post on the lower receiver we had finished welding it up and it looked like this. […] 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 […] 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 […] 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 […] 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. […] 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 […] |
