Just a quick post and a late one at that. I am a big fan of cut away guns as a learning tool. This is one of a bren gun I looked at while on one of my trips overseas.
A great deal of work went on this weekend and part of it was some work on the cnc router’
No, it is not up and running yet, however some of the components that were ordered finally arrived and we were able to start working on it again. The bad news is that some of the items we did order are not the correct parts that we needed.
The majority of work completed was minor as well as a number of solid models were drawn to start making our own parts.
As is always the case in any shop it needed to be cleaned off first so it could be worked on.
More work will be completed this next weekend, hopefully the rest of the material will be here.
With the gun room cleaned up I am now able to get access to some of the reference collection. This post is about the Egyptian Hakim cut away rifle.

If any one has a cut away weapon they would like to share please drop me a line.
In answering question concerning the post on the AR-10 belt fed light machine gun Ihave spent some time going through the ” The Armalite AR-10″ book. On page 314 of the book is a picture of a MG-09 light machine gun. The funny thing is that I had just seem that same weapon. It was on my back up hard drive and it was in a file of pictures of weapons that I had taken a while back. I had no idea what the weapon was, but that it just looked interesting so I snapped a few pictures of it.
This weapon bears a close resemblance to the T44 light machine gun designed by the United States after WW2.
These are the pictures I have of the MG-09. If you read the section in the book on page 313 and 314 it answers a few questions on the weapon.
A right side view
The feed cover assembly looks like a very simplified version of a cross between a MG-34 and MG-42 top cover. An interesting design that never got beyond a working non firing mock up. Mock ups like cut away guns are a great way to study small arms design.
Got tied up so just a quick basic post. On my last trip overseas I was able to snap a few shots of a belt fed AR-10 receiver so I thought I would share them with you.
This is a stock photo of the complete weapon.
This shows it open.
These are the photos that I took of the receiver area.
For more great information on early AR-10 rifles pick up a copy of the new book “The Armalite AR-10″ from Collector Grade Publications.
This weekend was again spent trying to make and install new gun racks for the gun room. Not as much work was accomplished as was hope for, a number for friends showed up with interesting and fun toys to play with and take pictures of. In addition it was my fathers 93 birthday and time was spent with him. I did manage to finish out three more gun racks and moved all the guns in the kitchen and living room back into the gun room.
I happen to like the Martini-Henry rifle and have a couple of them. So, I had a little space by the closet door and thought it would be a great spot for some of them.
Not that we have finished running the parts on the machining centers it is time to do the final fit up. Using the 1018 trunions that we made a hole was drilled in it to allow alignment with the button pressed into the receiver. Then the blocks were tested to see if the fit up was correct.
This is how the trunion looks away from the receiver.
Some de-buring still needs to take place and we still have a few cuts to do on the manual mill. If you are interested in any new MP-44 trunions please drop me a note and I will get the request to Pete.
With these last three operations we will have completed the work on the cnc machining center.
This is op 8. All we are doing in this step is to finish cut the curve under the trunion.
OP 9 then goes in and cuts the top of the trunion.
These two pictures shows the top roughed out just prior to the finish pass.
This is how they look after the finish pass.
All the trunions after the finish of op 9
It has been a while for a MP-44 trunion update. The next couple of posts will get us back up to date with the trunion project.
The new op 5 was to cut a slot and rough magazine opening to allow coolant flow and chip removal and still allow us to high speed machine.
Well it did not work as well as we had hoped. The chip load was so great as it was not removed as fast as it needed to be so we still had problems with the end mill chipping. So back to the drawing board. The answer was to put the trunion on the manual mill and drill the hole much larger but still under size.
The new process worked great. No chattering or broken end mills.
