With the last test model machined I started putting the lower together and a number of issues were noted. The receiver dimension is correct for the holes, magazine release, magazine well and overall length and width. the magazine button and release lever are not deep enough. These are the noted problems. The first one is […] A number of changes were made to the Sudanese AR-10 lower receiver. Selector stops were added and a new profiling program was used to allow for a better finish around a few areas of the receiver. Then a second lower was machined out of 6061 to verify the changes. During the process of machining a […] With op 1 completed it is now time to work on op 2 and 3. First a fixture needed to be machined to hold the machined receiver to all finishing the other side. The machined op1 piece was set in the fixture and tighten down All the holes were drilled in op1 so now the […] Over the last few weekend I have been working on trying to get the CNC router completed thus allowing me to finish the stocks and hand guards for the VG1-5 rifle. For every step forward there seems to have been 3 steps back. It is hard to believe that it has been over a year […] With the wiring completed on the angle connector plate The next item to be made is the side panel. This is where the fans and angle plate attach to. These are the pictures of it being machined on the HAAS machining center. Everything starts as a solid model and then a drawing to work from. […] With these last three operations we will have completed the work on the cnc machining center.
You can see the process of rough machining the bottom of the curve for the trunion. This op also machined the complete magazine well out. A good side view of the rough machining of the curve. All the […] With this post I am going over a few of the problems that have occurred during the machining of op5 on the 4140 hardened trunions. We ran into a snag while doing this op. A problem that did not occur on the 1018 steel parts. A quick video discussing the problem and solution. The […] 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 […] 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. […] |
