It appears that “DIY self defense”,(http://diyselfdefense.tumblr.com/) has gone off the air. It was a great site and he had cool stuff that he found and posted. It and Improv Guns (https://homemadeguns.wordpress.com/) were the only sites that dealt with home made firearms. I have always found it interesting what people can come up with when weapons […] In my list of want to do build projects building an original FAL is on the top. The very first FAL ever built was in 7.92×33 and was slightly different then the current FAL that we know today.
This rifle is missing and all that is left of it are the pictures you see […] An interesting question was brought up by Rick at http://ar180s.com/ a while back about making new AR-180B upper receivers. The actual receiver is not much of a problem however the trunnion is. The expense of making a new trunnion would be cost prohibitive so a different solution had to be found. In this case the […] 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 […] 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 […] This last weekend was a busy one, like most weekends here. On the list of projects that had to be completed was get the parts ready for heat treating. This meant bead blasting all the parts going to heat treat. Not a weekend of fun and frolic. Thousands of parts needed to be cleaned and […] 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 […] 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 […] 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. […] A friend of mine sent me a AR-180B upper receiver to look at and study. Here are a series of pictures giving you a more detailed look at it. This is a right side view. As you can see they were made with out a dust collector flap. A shot of the under side […] |
