Life around Gun Lab

Here are more up dates on the going on around here at Gun Lab. All the material was finally received for the new MP-44 and has been machined to size to start the whole process.

We are waiting for the tooling to start the next phase.

The spot welder arms need a little modification to continue the VG1-5 project. It has been milled to the proper dimension and the next step is to cut in the cooling flow paths.

We found a site that does an up-grade to Mach 3 and allows the use of touch off probes. This will be the next major programing improvement to the cnc router.

We received some really interesting cut away pictures from our friend, Axel, in Germany and will post them soon. Thanks Axel.

All for now.

Playing with the cnc router

Most of Saturday morning was spent with trying to get a feel of how to use the cnc router. The operating system is Mach 3 which is totally different then any other system in the shop. A number of items were learned during this operating time. The first thing was the e-stop is wired in wrong and needs to be fixed. The program would not single block, once the program was started it ran until the end. This problem has to be determined and fixed. The most important improvement has to be a better way to hold down material while machining. I am thinking of making a vacuum table to solve this problem. For our test run I design a basic part that involved no surfacing, still having a little trouble with that in Del-cam. This is the drawing in solid works.

router test1sBasically the program that was written to bring the stock to size and radius the corners, ten face it to reduce the thickness and finally cut two pockets one round at a depth of .250 and one square at a depth of .100.

Here is the video of the operation as it was performed.

 

As a first test run things went well. There is still a lot to learn about Mach 3 as well as fixing some of the glitches we came across.

There was no good way to locate the part in relation to X and Y so the laser edge finder was used.

DSC_5344csThe MDF board has not been mounted yet so temporary clamps were used. Working on that.

DSC_5343csThe final product does not look half bad. Del-Cam does not have a wood setting. The next part we will manually program that in.

DSC_5345csIn the long run this will be a very useful piece of equipment in the shop for making stocks and grips as well as making patterns for metal casting.

Weekend update for 5-18-15

Well it started raining on Friday and continue through Saturday morning. With everything being so muddy it was time for another game plan. I spent the first few hours doing solid works and taking pictures. Then it was out to the wood shop and spend some time with the cnc router. It was noon before we got the problems sorted out with the router, a post for tomorrow. By this time it had started to dry out and out I went for some fun in the fab shop. By the end of the day the cherry picker was back up and running.

DSC_5370s

Then both Star pistols had new firing pins and had been test fired and the third star was found to use a different size firing pin. Started working on getting the Model 1930 pistols back together, but did not finish that project, I will complete it next weekend. Sunday it was time to have fun pouring more concrete and the slab for the A/C unit was completed. But first the pad had to be prepped and the rest of the rebar set.

DSC_5347sThen 9 80# bags later this was the finished result.

DSC_5374sWent to the fab shop next. I needed to set up a place for my metal casting furnaces.

DSC_5372s

So more footers were dug.

DSC_5369sEnough fun and I am done for the day.

Are from a AR-180B rifle. This part is the bolt hold open device.

You can see the difference between the AR-180B and the AR-180 with this next picture.

DSC_2355scWith The AR-180B some additional parts are required.

DSC_5323csLooking at this next set of pictures you can see the difference between the two lower receivers.

The AR-180B was design to use as many AR-15 parts as possible. It was also a plastic injected molded receiver with a metal insert to act as usable surfaces for pins and wear points.

Here a few general picture of the rifle.

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_5012s

DSC_5014s

DSC_5011s

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.

DSC_5280s

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.

DSC_5240cs

 

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

DSC_5232cs

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

DSC_5216cs

DSC_5215cs

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_5182cs

DSC_5185csStill using the rear tubular magazine and not magazine fed.

DSC_5187csThe front nose cap remained the same.

DSC_5190cs

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_5196cs

DSC_5199csThe same basic nose cap was kept.

DSC_5206sThe butt stock and plate were once again changed.
