I don’t want anyone to think that here at gun lab we have just been hanging around and drinking beer and accomplishing nothing. That is far from the truth. A while back a die shop went out of business and I was able to buy a few items. One being a brand new steel die […] Well we have just about completed all the front barrel supports. So the next few posts will be videos of cnc machining the last two ops on the cnc lathe. We have actually started on the rear barrel supports now. Today we are going to stamp and machine the trigger guard. We start with a sheared piece of 2 mil sheet steel. Initially we tried 1 mil but found that it was to easily deformed. Next was 1.5 mil and still did not look correct. So 2 mil gave us the correct look without too […] Well more work has been completed on the solid model of the type 99 magazine. We have now finished both side with feed lips and bottom plate rib. Soon the follower and lower spring plate will be completed. When all the parts are completed it will be off to the 3-D printer. Here are a […] We are going to take a short break from the lower receiver and do some work on the upper rear top cover. This piece is what holds the ejector in place and covers the rear of the upper receiver. In the original rifle it also contained the fire control mechanism. Due to the changes that […] An opportunity has come about to possibly buy a Japanese Type 99 Nambu light machine gun. Years ago I owned one and enjoyed shooting it. I still have ammo and reloading equipment and kind of always wanted to obtain another. The problem with Japanese machine guns is the lack of spares and magazines. I bring […] Now that we have the two halves ready to spot weld together we first have to install the strengthen plates to both sides. The major purpose is to add material for the magazine release assembly. These plates add extra material to make a sturdy mounting area for the magazine release. Historical note – we are […] Now that you have seen the concept models it is time to get into the nuts and bolts of making this. So the first step is cutting the 16 gauge sheet metal to the proper size. This is no easy task as we do not know what the starting size is. So we cut the […] This project isn’t strictly speaking about gun manufacture, but is related. I’ve had a semiauto Browning 1919 for a while now, and I finally got my 1946 Jeep up and running. Naturally, this means that I must come up with a way to mount the one on the other – my 10-year-old would curse […] We have a friend in full-scale firearms manufacturing who was looking at making a large run of 1911 pistols. In order to reduce his machining costs, he bought a sample batch of frame and slide castings from Coast Metal Casting – and they turned out to be next to worthless. So we borrowed a set […] |
