Video on making the FAL by DSA



There are some real good segments in the video. One showing the stamping of magazines.

Cut away CZ 75

This series of pictures is from a CZ-75 cut away in my collection. I really enjoy cut away weapons. It is a way to study the operation and fit up of a particular weapon. Enjoy the pictures.













Your opinion of the pictures. I really am trying to improve the quality of them on the site.

If anyone has any pictures of cut away weapons please drop me a line so I can share them with everyone. Thanks Chuck

Gun Lab update

Not a big post for today, just an update on the projects we are working on.

First and most important is the VG1-5 project. I received a call this afternoon late that the firing pins can be picked up from the heat treating firm. With this last piece we can send the second rifle to the ATFE for final testing. The second item on the VG project is that all the receiver flats are in the spot welding room and as soon as we modify the spot welders they will be on the line to finish. That will be this week.

The drawings for the MP-44 trunnions are solid modeled and material is ordered so we can finish that project.

The Japanese type 96 and 99 magazines have taken a step back. The first two stamping dies did not work as planed and we needed to send the magazines back. They are still on the drawing board as I need them for my own guns.

The AR-16 is still being solid modeled. We are getting closer but still more time is needed to finish this project. I only work on it when I have spare time and we know how that goes.

A member of our family here at Gun Lab located me an isolation transformer and with that I hope to get the wire edm powered up.

We have been doing a reverse engineering project on a German WW2 machine gun which is coming along nicely and I hope to have drawings in the near future and a solid model shortly after that. This project has been a real ball buster, but with the use of the schools cmm we are getting close now.

I am currently work on a few write ups for the site. Part 2 of the Winchester self loaders should be dome this week, a friend , O.H., is sending me some interesting photo’s and scan’s on a few weapons to post and the third installment on the Bushmaster pistol is in final editing.

This should answer all the questions that have shown up in my in basket. If there are any other question please feel free to drop me a line.

I do need help with a project though. I need manuals for the wire EDM. I am concerned that the batteries have died in the controller and I am going to have to reset the parameters. This machine came with no manuals at all. Here are a few pictures of the panels and model numbers.




DSC_5009sXerox copies are fine. I just need to learn about the parameters and set up of this machine. Thanks everyone for helping.

With nothing else going on I am going to hit the rack, tomorrow is another fun filled day for me.

The Winchester self loading rifle part 1

I happen to enjoy all types of firearms. From single shot to machine gun. From civilian to military and caliber does not matter. Generally I like to chat about projects we are working on or building small arms, but this series of posts are going to be about the Winchester self loading rifle. The first post will deal with the Model 1903 self loader and its successors the Winchester model 63 and the Taurus copy of the model 63.

When the Winchester model 1903 first came out 22lr ammunition was not of the same quality as 22 ammo is today. In fact a large portion of it still used black powder as its propellant. Therefore to insure a rifle that would work properly and not  gum up due to the residue that black powder leaves behind a new cartridge was developed. This cartridge was the 22 Winchester automatic. This round fired a 45 grain lubricated lead bullet with a muzzle velocity of 1055 fps and a muzzle energy of 111 ft-lbs.


The picture above shows the difference between the two cartridges.

This rifle used a tubular magazine. The clip as we know today was not developed unit 1919. Loading ammunition while shooting all three of the rifles was easily accomplished, but care had to be taken to insure that the round were dropped in properly.



The production of the model 1903 rifle ended in 1932 with Winchester making a little over 120,00 units.


DSC_5218csThe curve of the butt stock was more along the lines of a lever action and not a semi-auto rifle.



DSC_5214csBy 1932  22 ammunition improved in quality enough that the rifle was re-design for this caliber and the model designation was changer to model 63. All together approximately 175,000 were made and sold.


DSC_5185csStill using the rear tubular magazine and not magazine fed.

DSC_5187csThe front nose cap remained the same.


However, now the butt stock was more into the design of a semi-auto rifle and checkered.

DSC_5192csThe third rifle is not a Winchester but a Taurus copy, also called the model 63.

DSC_5204csYou can see that changes were made to the feed slot for the tubular magazine. The slot is longer and at a much more gradual taper.


DSC_5199csThe same basic nose cap was kept.

DSC_5206sThe butt stock and plate were once again changed.


Weekend update 5-11-15

Most of this weekend was spent taking pictures for up coming write ups and going through some 1480 scans, I just got back from the scanning company, to organize them. But, some other projects were accomplished as well. The first was a new pad for the a/c unit for the cnc room. The compressor is currently located in the band saw room. However, there is to much heat build up in this room. The air compressor, air dryer, and a/c compressor exceeded the max heat load. So a new footer and stem wall was built. Here are a couple of quick pictures.

DSC_5124sThis was done the old fashion way.





Next I made a couple of hole down nuts for the cnc router mdf board.


Sunday was spent on more picture taking and working on the wire edm. The first item on that list was getting the coolant tank up on a new set of wheels.

I just have to get the tank and pumps on this rolling tool stand.

DSC_5129sYou can see the tilt due to a broken wheel bracket.

DSC_5130sThis was accomplished with a cherry picker

DSC_5260sAfter a little work it finally came to pass.

DSC_5252sNext came the task of hooking it all back up.

DSC_5251sThere were wires and plugs to connect everything. After this it was time to hook up power and see if the controller still worked. Then it hit. The transformer tripped its breaker. So after a little trouble shooting it was determined that the transformer is bad.

DSC_5253sSo if anyone knows where I can get a 230 to 200 3 phase isolation transformer rated a 7KVA please let me know.

DSC_5111sWhat you are looking at is the spigot stem to a “Bigot”. For those of you not familiar with this weapon it is a dart firing adapter for a 1911 pistol.

What is it Saturday 5-9-15

Another hard one, but it is a gun part.


Archive Photo of the Lowell Gun

Here are two pictures of a Lowell gun. It came out during the time of the Gatling, Nordenfelt and Gardener gun but at the very end of that time period. Only a few were ever made and I was lucky to photograph this one before the museum closed.


scan0006c2csSome where in the archives I have more pictures and will post them at a later date.

From the days of 35mm photography.
