Update on the MP-44 trunions op6

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.

DSC_8273csWith the trunion on the lower left we did just that. What a difference that made. So now with all the trunions drilled with a larger hole we were back on track.

The new process worked great. No chattering or broken end mills.

Making a Hotchkiss Portative tri-pod

After the last machine gun shoot with the Hotchkiss I made a decision that what was really needed for this gun is a tri-pod. I did a post a while back about ideas for the tri-pod, http://gunlab.net/hotchkiss-portative-tri-pod-ideas/, but now I am on to the project, in my spare time of course.

I was down on a job a week ago in Tucson and when I finished I stopped by Omega, Don Bell’s shop, to say high and check in on him. While I was there I came across this little beauty that Don offered to me at a really good price,free, for the project.

With a basic set that was with in my price range I could not say no. It is a Chinese tri-pod for a recoiless rifle.

The first step in the process was to clean all the rust off and paint a coating of primer on it.

DSC_8604cWith the tri-pod back together for a quick photo op. I kind of like the look.

DSC_8611csIt will require a yoke and cradle of some type.

DSC_8612cs

I wanted to paint it the same color as my Vickers, a Syrian desert brown.

DSC_8609sA close up of the color.

I lost out to my wife and went with basic black.

DSC_8689sThis is after the first coat. A couple of more coats this coming weekend

DSC_8690s

The first part to solid model is the pintle support’

pentelwith this part complete I could start working on the basic pintle design.

yolkThis is all that I have left after the new computer ate the rest of the solid models. Actual it is not much of a loss as I was going to change the basic design from what I started with.

New gun racks for the reference collection

A friend of mine recently lost his house. By this time he had already sold most of his collection and had no need for his gun racks. While not exactly designed for my gun room they were at least a start and the material was free, my price range. It took me all day Saturday to take down and remove the racks piece by piece to get them out the door. So Sunday was build new racks for my room. I am still not done and have at least three more racks to build. That will be next weekends project. As with all gun rooms there is never enough room. This was what my room looked like on a couple of  walls before I started.DSC_0286_s

DSC_0283_sNot much space and guns stacked upon guns.

The first project was to take the guns from the south wall out so I could work. The only place to store them was of course the kitchen.

DSC_8657sThis freed up the space to start the first rack.

DSC_8659sThe base was first.DSC_8661sThen I made spacers between the hanging racks to support the upper part.

DSC_8663sWith all the spacers installed.

DSC_8664s

DSC_8665sThe upper portion was hung and the first set of small arms brought back in.

DSC_8666sNext the space above the cabinets was cleared off and a new rack made there.

DSC_8667s

DSC_8668sThen the rifles were put back there.

DSC_8669sThe next wall was attacked and cleared out so new racks could be installed. This time we made them two high instead of a single level.

DSC_8670sA smaller rack was made and installed next to the cabinets to hold shorter Mauser rifles.

DSC_8672sThe 34 and 42 were move and new racks built and installed.

DSC_8675s

DSC_8673sAgain a double rack design was used.

So at the end of the weekend I was able to remove two of the round racks built 5 new ones. Next weekend I will finish the rest as I am fairly sure my wife wants the kitchen back and the rest of the guns and swords removed from there.

 

DSC_8679s

There is still a bunch of wood left to use up for the remaining racks.

 

DSC_8684sMy guess is that she will want me working on them every night this next week.

 

Shooting the Hotchkiss protative

At the last machine gun shoot I spent a great deal of time playing with my Hotchkiss light machine gun. I enjoy it like I enjoy my Lewis gun. That is to say a lot of things are going on to make the gun work. It is just a fun gun. There are a few quirks about this machine gun.

The first is you really need to be careful when loading the feed strip.

DSC_8620sw

DSC_8624sw

DSC_8626sw

DSC_8367csw

DSC_8368csw

Both of these strips were damaged when I tried to load them without looking at the position of the feed strip in relation to the stripping bar. They would go in but it jammed the gun and damaged the feed strips. Effectively making it a two man weapon or a very slowly loading one man weapon.

The next major concern is the tri-pod  that was used with the gun. While shooting it off the table if you were not holding the tri-pod while firing the weapon it would tip over. I tried shooting it with the tri-pod in the forward position as well as the rear position and the same problem occurred.

The stock was the next issue that I had. There is no check weld of any kind. There was a weapon used  by the light horse in WW1 that had a wooden stock. This one was hand made by the owner of this weapon.1He did really nice work

This stock at least attempted to solve this problem. The two stocks that I have are the metal types. With and with out a wood wrap and should support.

DSC_8629cs

DSC_8633cs

Another thing that you will have to get used to while shooting the Hotchkiss is the weight of a full feed strip hanging off the right side of the gun.

With all this said I really enjoy shooting it. It is just a fun gun to shoot and with the availability of spare parts, http://www.ima-usa.com/original-british-wwi-303-cal-hotchkiss-portable-machine-gun-mk-i-parts-set.html, I don’t feel bad if something breaks.

As if anything could break. Now that there are spare barrels and bolts people are doing conversions to 7.62x54r.

This also one of those weapons that has really cool accessories.

There are Strip loaders in both 303 for the British guns

and 8×57 for the Turkish guns, this one will also work for the 7×57 guns as well.

DSC_8644csThe fun is in the shooting. Here is a slow motion video that we took at the last shoot.

Here are a couple of interesting drawings of the gun as well.

Projects update.

I would love to post a video of shooting a Hotchkiss machine gun, or the post dealing with the VG1-5. How about a post on the new Hotchkiss tri pod I have been working on. There is also the post on the MP-44 trunion and where we are on finishing them out. There are also 2 book reviews that I wanted to post. I could also write about the Vickers feed block conversion to use MG34/42 belts. I had a really nice video and post on boy’s rifles.

However, instead of writing about these thing I am going to write about the new computer I bought. It is a top of the line HP. It has a very fast processor, a great video car and one terabit of memory. The most interesting thing about it is that it is a piece of SHIT. The damn thing dropped the hard drive connection  and then lost data so all the post and editing has to be done again. It would lock up for no reason and may start up again if I turn it off and then on again or it may not come back for hours for no reason. The last straw was when I just finished a long and grueling day and when I went to make copies of all the videos and pictures I did for the client to just crashed the hard drive. So let this be a warning. DO NOT BUY an HP piece of crap with windows 10 on. You would be better served buying the cheapest piece of Walmart junk then an HP.

The hunt is on for a new computer that is not HP or dell. That was 1700.00 down the toilet.

I will try and get another post back tomorrow.

 

Cut away Enfield pistol

It has been a while since I have posted any cut away pictures. This one is on the Enfield N02Mk1.

Left side view.

IMG_0212csA slightly better picture.

IMG_0218sI really like cut away weapons. It is a great way to study them.

If anyone has any cut away weapons they would like to post please contact me. I am always look for them

Fixing the 1919A6 barrel

This is kind of an after action report on the 1919A6 barrel that was involved in the accident. The last post on the damage to the 1919A4 due to some Turkish ammo showed a barrel that had a case stuck in it that the base was sheared off.

DSC_8374scwWith the cost of everything these days there was no way to not try and get that barrel back into operation.

The first step was to use a broken shell extractor. I have one or two of them

DSC_8572ssThe ones we tried that acted like they might work.DSC_8574csThey did in small way. I was able to remove the neck and shoulder of the case with them.

DSC_8554casWith the neck removed I used my chambering reamer to slowly remove the brass case. After about 20 minutes of running the reamer in then cleaning it I was able to remove the remaining part of the brass case.

DSC_8589cs

DSC_8590csThe barrel is as good as new and ready to be used again.

 

The machine gun I love to hate

My least favorite machine gun is, drum role please, The MG-34. I like the way they look. I fine the accessories interesting.Like this fortress box.

DSC_8537sOr saddle drums.

DSC_8535s

The history of the weapon is fascinating.  However, after owning three of them over the years I can say with certainty that it is the aggravating machine gun that I have ever own. This includes the one I have now.

DSC_8532s

DSC_8534s

DSC_8533s

With this machine gun you need tons and I mean tons of spares. Extra Barrels.

DSC_8543sBolts and misc parts.

DSC_8546s

DSC_8548s

 

I bring this up now because at the shoot I met a very nice gent that actually love his MG-34. The weapon that he had there was a beautiful example of a MG-34. He had converted it to 308 and shortened the barrel and shroud to a smaller size. It is a very nice looking gun.

DSC_8340sHowever, the most interesting part about this machine gun is this photo.

DSC_8341sDo you see it? That is fired brass under the gun. Now I never actually saw it fire and I don’t think Wally, a friend of gun lab, would just throw empty cases under his gun to make it look like it had had worked. But the only time mine has had that many fired cases under it was when the machine gun next to it was ejecting them there.

More on the type 63 Chinese rifle

I kind of like the look of the type 63 rifle and a goal is to eventually make a semi-auto ATFE legal one for my self.

chinese3It really has a nice look to it.

chinese2A couple of close ups.

chinese4

chinese5These last 4 photos were pulled from the internet.

So I have had a quest for the last 15 years or so to obtain type 63 parts. Not the easiest task. This last week I was able to obtain a few more parts for the type 63 Chinese rifle.

My stock as it sets now is:

8 barrels.

DSC_8512csSeven complete bolts.

DSC_8518csMore then enough top covers. Interesting that there were two different upper hand guard designs. I still need to make some more recoil spring brackets.

DSC_8519cs8 fire control groups

DSC_8521csI have enough front hand guard sheet metal pieces as well as gas pistons and locking pins.

DSC_8515csSks bayonets and springs and latch mechanism. The bayonets need to be re-ground and shortened but will work. I am going to cut off the latch mechanism on the sks and weld on a type 63 mechanism.

DSC_8516csI have 2 stocks and a stock duplicator. I can make the rest of the stocks I need.

DSC_8524csA great little piece of a cut off end of a type 63 barrel. I will have solid models of both of these parts soon.

DSC_8522csA close up of the type 63 lock up and the sks lock up on the bayonet lug.

DSC_8436csThis is a Chinese folding bayonet for the AK-47. This is still available even if it is quite expensive. I will order one this next week to have to use as a pattern.

DSC_8477csA view of the gas block,rear sight base and gas system, this one is missing the gas tube. I do have 2 gas tubes to use as patterns.

DSC_8429csA close up of the gas block

DSC_8471csI am hoping that one of the readers of this happens to know of or own a type 63 and can take me some detailed pictures of the receiver of the rifle, hopefully with some basic measurements. I could also use some pictures of the gas block with measurements. With any luck I will be going to England this summer and have an opportunity to look at one at the pattern room.

This will be a project in the future.

What is it

It has been a while since I have posted a what is it. I was up in the container cleaning up and looking for parts for a project I was working on this last weekend and came across this. It is a casting of some kind of mount. Some machining has been performed but it is far from complete. I am trying to determine the weapon that it goes to. Any help would be appreciated.
