Full Auto pistol part 3

This is the third and last post on the prototypes full auto pistols. This is also my favorite of the pistols we have covered.

It is a cross between a CZ52, Browning high power, and some original ideas. You can clearly see the Cz slide in these pictures.

The first couple of pictures show the left and right side views of the pistol.

Cut away weapons

By now most of you that come to this site know that I have a thing about cut away weapons. They are a great tool in understand how weapons work and in my case allow me to see the functioning of the guns that we make.  I own a number of cut away weapons and have photograph a number of other ones as well. As I am always on the look out for them I thought I would share some of them that are currently available at the Cowan Auction house.

To begin there is a Enfield cut away rifle, lot 195,  http://www.cowanauctions.com/lot/cutaway-lee-enfield-rifle-186031/

Mk4 Webley .455

Unfortunately I have no Mk3 pistol in my collection, maybe someday. The next in line is the Mk4 pistol in .455. This pistol was accepted into service in October 1899. Commonly call the Boer war pistol. It was the pistol supplied by the British government for troops sent to South Africa to fight the Boors. The Mk 4 was a very well design and serviceable weapon as no changes were made to the weapon for the next 14 years and then only when the Mk5 was introduces in 1913. The pistol remained in service through WW1.

Webley Mk2

The second pistol in the series in the Mk2 revolver. By 1894 a number of changes had occurred to the Mk1 to warrant a new nomenclature. Thus the Mk2 was born. The modifications that occurred were to the frame, hammer and the changing of the machined in shield to one that was a separate hardened steel shield.

Webley Mk 1

I have decided to do  a short series of posts on the Webley and Enfield revolvers in my collection. The first of the series is the Mk1 455 revolver.

The one in my collection is a cut away pistol.

This is one of any order of 10,000 pistols bought in 1887. This pistol was later converted to a armories cut away gun. All Mk1 guns were black powder guns.

Unusual Vietnam 22 pistol

 

Ken, a friend of gun lab, sent us a very unusual 22 pistol that his father-in-law picked up while serving in Vietnam. It appears to be factory made pistol. However, I have never seen another one like it.

This is it.

Weekend update for 7-10-16

Every weekend I have a list of projects that I want to do. Generally I can get through only 15% of what is on my list. This weekend it was even less then that.

With the summer heat this year, generally the same every year, it has just gotten to me for some reason. Probably due the A/C going out in the clean room and in the wood shop. Both of the units were small and really over taxed but they kept the temperatures down enough that you did not feel like you were sweating to death in the shop. Starting last weekend I made the decision to actually install heat pumps in both shops. The duct work has always been there but it was designed for an evap unit and not actual A/C. That is out after the serious rust issue that I have been dealing with.

Last weekend I ran the new wire for the 4 ton unit for the machine shop. This weekend my wife bought it and we unloaded it from the back of my pickup truck. With the backhoe still down it was another fun filled exciting weekend . It is how ever down on the ground and wired in both power and control.

DSC_0319s

The duct people will be out this week so I can do up drawings and these I will have made.

For the wood shop it needed a little more work. I first had to get a slab down for it and for the size that meant that I could not order it in it had to be mixed on site all 35 bags. However it is now done and that A/C unit will be picked up this week and put on the pad.

DSC_0328s

DSC_0336s

Still dealing with the heat and the fact that the fab shop will be coming soon on the shop to work in list it was decided to get the evaps working in there. This is one of those projects to complete at step “Z” you first had to start at step “A”. The fab shop had gotten a little out of hand in the past couple of months. The first step was to store somewhere all the cabinet fronts that I demo out of a house, these will be used in the wood shop.

DSC_0326s

DSC_0322s

Then a total clean up and up away project commenced. All the casting equipment had to be stored away as well as all the tools laying about.

DSC_0329sYou can actually walk down the isles.

DSC_0331s

Then the new sheet metal ducts that we did a while back had to be installed and the evap coolers flashing installed and coated down. The the evaps were moved into place.

DSC_0332sDesigning and making duct work is not my strong suite.

DSC_0333sThe evaps just setting on the roof.

DSC_0320sThe first evap installed.

DSC_0334sA better picture showing both evaps installed

DSC_0335sSo then what did not get done off the list. Well first is the parts that I wanted to make on the 3d printer. I did not get to make the AR-16 pistol grip on the stock duplicator off of the 3D print that I wanted to make. I also did not fire up the wire EDM. I finally finished writing a cutting program for it. I also have not finished the water system for the fab shop evap coolers. I did get the duplicator moved but did not finish the dust system for it.

I also have not finished the video’s that I have been working on or the gun post that are setting on my computer.

Full auto pistol part 2

In our first installment. http://gunlab.net/full-auto-pistols-prototypes-part-1/, we looked at a rather boxy looking full auto pistol. This post is about the weapon that was built for patent number 3,803,976 that was issued to Henk Visser.

visser 129cI am not sure but I think that these are proprietary magazines for this pistol only. I can not remember seeing them anywhere else.

This pistol had a nice feel to it and was easy to operate.

Many thanks to Daniel E. Watters for locating the patent for us all.

 

 

 

 

 

 

 

 

 

 

 

 

 

Weekend update for 4th of July

Like all weekends I started out with a list that I could not possibly get done in the time frame allotted.

There were projects that I have been wanting to accomplish that are fun. Some of the things I needed to finish were under the direction of the commander in chief of the house. Some projects are necessary to finish the VG1-5 project. And some just needed to be done.

I started my Saturday morning with trying to get the pistol grip of the AR-16 rifle 3D printed. The PLA that came with the 3D printer is old but seemed to work on the first few projects. That was not going to be the case this weekend. The material did nothing but continue to break off in the feed tubes. After spending a few hours on this I just threw my hands but and ordered some new material.

DSC_0150s

DSC_0151s

DSC_0152sI hope to back on this project next weekend.

On to the next project. This is doing a little upgrade to by duplicator. I have always found it to set to low for me so I wanted to raise it and changed where is sat slightly. I was able to put the risers on it after a little adaptive engineering.

DSC_0137sHowever, when I went to look for my Johnson bad and skates, about an hour of looking, I could not find them anywhere. A friend borrowed and I will have them back on Tuesday. Then like a fool I tried moving it with out them and not such a good idea. More on this later.

So now off to another project and that is one of the trees at the house has been a little sick and needed to come down, this was a project handed down from the commander. So the task was set into motion. All the limbs had been cut down and taken to the dump all that was left to do was use the backhoe and remove the rest of the stump.

DSC_0133sThe backhoe decided to take the weekend off. Nothing would get it to start.

I wanted to install new A/C units in the wood shop and machine shop. With the temperatures that we have been having there is no joy in working in the shops. To do this in the machine shop I needed to take down the evap cooler first. This little project took several hours and was not the least bit of fun in the 110 degree heat.

DSC_0134sHowever the A/C guy called about 2 in the afternoon to inform me that he did not pick up the units and it would be next weekend before they would be out. It was okay as I still needed to run the new electric line for the A/C’s and while I was at it I would change the wiring around a little. I also needed to install a return air duct. To do this work I first had to move the bead blaster.DSC_0140sThen cut the osb and sheet rock off the wall.

DSC_0141s

DSC_0148sThen the wiring was run for a new 40 amp circuit and set up out side with a new disconnect.

DSC_0146sI went to use the small air compressor in the wood shop, the big one needs a new motor and that is another project for another day. It has been acting a little iffy lately so a new pressure switch was ordered and received on Friday.

DSC_0147sOnce again Murphy came back to visit. The switch that was ordered and suppose to work was not the correct type.

DSC_0143wwOnce again the weekend did not go as planed. In addition to all the fun I had in the 110 degree heat some where along the line I pulled my back and could hardly walk,sit or lay down without being in great pain. Not sure if it was the trying to move the duplicator, taking down the evap, dealing with the tree or running the new electric. At that point I just threw in the town and took my wife to the movies.

 

 

 

Update on the VG1-5 project

We have been working on the fire control group and once again have made a few changes for more reliable operation and safety. We continue to have issues with the disconnector operating properly. There were issues with the hammer spring improperly contacting the disconnector. An additional problem came about with insufficient spring pressure to hold it in it’s proper position.

This is the old style of disconnector compared to the new style.
