Making the VG1-5 strengthening plates

In this post we are going to take you through the steps necessary to make the strengthening plates for the side of the VG1-5 receiver. In the first couple of rifles that we made we bent the plates on my finger brake.

DSC_3434sThis was not a plan for doing over 200 of them. The time necessary to measure and mark each one and then eye ball the bends and fit to the receiver would have been enormous. To do this in an efficient manor that insured that they were all the same and would fit correctly a press tool had to be made. This are a couple of solid model pictures to get an idea of what it should look like.

In this last photo you can see where the laser cut blank set.

DSC_3430s

DSC_3431sThis last two photos show the angle that we pressed to. These photo’s were taken after all the pressings have been completed. The press tool was made out of 1018 steel and the wear from pressing 210 pieces was non-existence. If we were going to press thousands upon thousands of them we would have gone to heat treated steel.

Now on to the actual making of parts. This is what we received from the laser cutting people.

DSC_3382sThe parts were cut and cleaned from them. A slightly better look at them.

Now a quick video of pressing them.

 

 

The final part after they were all pressed.

DSC_3391sEvery one of them exactly the same and ready to install on the receiver. Just for an idea of the time to accomplish this part.  It took 2 days to design and build the press tool and about an hour to do the pressings. If we would have stayed with the old procedure it would have taken days to accomplish and the repeatability and accuracy would not have been there.

Weekend update 1-5-15

Well the new year is here and the holidays are over. It is time to get back into the routine of life. This last week was just that but a little longer. The first on the list was the honeydo’s  project. My wife wanted a new kitchen faucet for Christmas ,seeing how the old one had cracked and died, and I got the pleasure of installing it. Now before any of you get on my case about buying a faucet for my wife for Christmas and not something like jewelry, witch I make, or cloths, which I would never guess at, she bought it her self. In fact she buys all the gifts because I have no since of humor shopping. This is a picture of the old faucet and you can see why it needed to go.

DSC_3348sThis what she bought to replace it.

DSC_3307sNow the fun starts. There is nothing I like better then to get my old and over weight body down on the floor and try to squeeze into a small space and work.

DSC_3349s

DSC_3351sThen to only find out none of the hoses match up between the old faucet and the new on. So a trip to home depot to buy the necessary components and back on the floor again and we end up with this.

DSC_3352sWhile we are on the subject of honeydo’s my next door neighbor decided he needed a new tv. The large 63″ one in his bedroom just was not big enough so he bought a new one that was larger and was going to throw out his one year old one because it kept shutting down after 30 minutes or so. Because he had trouble moving it by himself he gave me a call and asked if I wanted it. Not one to turn down free stuff I said yes. It is now in the living room where it replace my 34″ set. And the timer has been reset so it operates great.

DSC_3354s

DSC_3355sIt took a while to get working and new cables have to be bought, as it is high def and our old one was not. I still can not get use to the size. It takes up the wall.

Now on to shop things. Most of this weekend was spent working in the wood shop and as the weather was a little chilly it was a good idea.

DSC_3316sYes, that is snow on the mountain behind my home.

Now, back to the wood shop. A couple of weeks ago I picked up some new, for me, wood working equipment. With the new additions I needed to make some changes to the shop. It seems a number of  people question my sanity for getting additional wood working equipment when I spend most of my time in the machine shop. There are two good reasons for this. The first is that I need to make stocks and metal casting patterns for some of the gun projects were we are doing. The second is that I started a complete house remodel a few years back and got stopped at the kitchen. I bought a kitchen store display cheap but when I went back to buy the additional cabinets to finish the kitchen the costs were out in the “O MY God” price range. The same is true when we contacted a number of cabinet makers in the valley. Not to mention that I am now sure that cabinet makers are one step below used car sales men in honesty and integrity. So I have decided to make the remainder of the kitchen cabinets because I have nothing to do in my spare time.

So,with the new tool I got for Christmas I got busy.

DSC_3312sI finished the back table for the table saw.

DSC_3375sA cabinet needs to be built for inside the stand. That project is coming up as soon as I finish the drawings in solid works.

DSC_3376sThen we move the radial arm saw to a new location to make it more user friendly and started build a larger table for it. This next series of pictures is that process.

DSC_3368s

DSC_3357s

We started with the old bench that I had in the shop, I got it out of a dumpster a while back and liked it. However it was to low for the saw and needed to be raised and there was a slight rise in the table so everything had to be hand fitted.

DSC_3363sBut by the end of the weekend we had it mostly finished. I need to pick up a 1.5″x2″x16′ long piece of steel to finish the job. This is how it looked when I stopped.

DSC_3374sThis weekend I also took a class for K. who is a professional photographer, and works for a top gun magazine, to try and improve my pictures. This is the photo I took at the beginning of the session.

DSC_3322s

DSC_3325sAnd these are the same shots at the end of the session. I was lucky enough to be able to spend a few hours with her and learned a great deal. With any luck I will be able to do it again.

DSC_3328sNo photoshop magic was done on any of them.

And as they say in the infomercials, BUT WAIT THERE’S MORE.

I also spent time in the machine shop working on the new parts we just got in fro the laser cutter for the VG1-5 project. I finished the magazine release button and the strengthening plates for the receiver.

DSC_3404sA complete write up will be coming in the next few days along with videos. I also spent more time on the AR-16 drawings to try and get that rifle finished up in solid works. Other then taking my wife out to the movie and a few clean up projects this was my weekend. Tomorrow I will post an update on the VG1-5 project and all the other projects we have been working on here at Gun Lab.

cimg76271024x768lsI use to own one of these when they first came out, wish I would have kept it.

 

What is it Saturday

Tokarev 22 trainer

I kind of have a thing for Tokarev pistols.  I do have a variety of them and I also think they are one of the interesting hand guns to come out of WW 2. They combined the design of John M. Browning with the manufacturing techniques they had available. I am not going into the history of the TT 33 Tokarev, it has already been written about on the internet . I just found on my trip through the mid-west this last year a new version that I have never seen before. The 22 trainer. Here are a set of pictures that I took of one of the pistols that I looked at. It seems that everyone out there has one because I saw a number of them.

DSC_1419csSorry about this picture. I tried to get a close up of the slide bolt face to show the firing pin location.

DSC_1421csThis is how it came with the 7 sub-caliber devices.

DSC_1423csI don’t know if this pistol was actually used in the military training or just a pistol made for the civilian market. I just know that I would really like one. So if anyone knows were one exists one for sale please let me know.

Making the miniture Gardner Gun “The Receiver”

In this post we will start with the making of a miniature Gardner Gun. The very first step that Joe did was to find someone with a Gardner Gun that would allow him to study and measure it. That was no easy task but one that he prevailed at. Joe spent a number of months just taking measurements of a full size Pratt and Whitney model Gardner Guns and converting them into a solid model in solid works. After gathering the information on a full size weapon he started the process of converting it to 22lr. His first attempt upon completion of the drawings was to make up a wooden mock up to get the basic concept to work from.

With this he had a starting point. Now it was time to convert all the data he had collected into semi working plastic model. This allowed for the checking of dimensions and operation of the weapon. It was also hoped that this would also provide the pattern for the castings. That would not be the case.

It was now time to self-educate himself on wooden pattern making and metal shrinkage. After a number, it took three attempts, of patterns he finally came up with a design that would cast properly. A number of problems that you will generally not find in books occurred. A few of the examples are getting the metal to flow properly, is the casting area to thin. How do you hold the cast part to machine it. Is there enough metal to machine away the rough surface. Is there to much metal causing extra machine time. Is the metal going to sringe to much causing an out of spec casting.

DSCN2911cThis is the wood pattern for the outside shape of the Gardner gun.

This pattern is for making the core mold. It took a number of attempts for this core mould as well

DSCN2913cAfter casting the raw bronze casting with the sprues cut off would look like this.

 

DSCN2910cIn our next post we will go into the work necessary to machine it.

AR-180 part 4

With this post we are going to discuss the stock.

The first set of pictures will be the plastic stock. You can see the parting line on the stock from where it was injected molded.

DSC_2405csIf anyone has a wood stock AR-180 I would love to post pictures of it.

Weekend Update 12-29

Well this was a moving Saturday. I needed space in the fab shop and after looking at the deep hole drilling project for the last 10 years I figured it was time to move on. So with that being said it was time to move the big old lathe to the scrap yard. The first challenge was moving it across the fab shop. That was accomplished a couple of weekends ago and now it sat in the major opening and blocking everything.

DSC_3065sNext on the list of fun projects I needed to get up and onto the trailer. This was an all day Friday project. Normally my friend MacGuyver would be able to accomplish this task  in no time flat. However I am not him and it was a real chore for me. The back hoe was not able to pick up the lathe as a single lift. I tried and the upper hydraulic seal did not like it at all. Now I have to remove the cylinder and get it repaired. I took no pictures of the moving endeavor as truly it was just a little scary. However with a great deal of effort two old guys did get it up and on the trailer.

DSC_3291s

DSC_3293s

DSC_3294sI did have to remove the cross slide prior to moving the lathe. As there was no one to help I did that myself. Not one of my smartest ideas as i suffered all day Saturday because of it. Still worked but just in pain.

DSC_3296sSaturday was honey do and wood shop day. We finished the making the table top for the back of the table saw. But first before I could go out and play I had to rebuild the toilet and change the angle stop. The fun never really stops around here. The table top for the table saw has been completed and is now useable.

DSC_3308csThe next part was to make the legs for the top. To do this I used my Christmas present, A Kreg drilling fixture. What a great little tool.

DSC_3312sThis allowed me to build the legs with little problem.

DSC_3310csThis is how they will look when installed.

DSC_3311csNext weekend I will remove the clamps, attach the legs and finish the cabinet that goes under the top.

 

 

Christmas Gifts

This one that my son received. It is such a useful item that I just had to post it.

DSC_3278cNot only is it a fork for Bar-B-Qing but now you can do it at night.

DSC_3279cBe sure to check out the warning on the box.

To aide in the bar-b0q experience there is also a laser  to help you aim the fork.

DSC_3280cAnd you can also use the laser and light if it is a difficult piece of meat.

DSC_3281cThe fork is also equipped with a mounting rail to allow the removal of the laser and flashlight and the installation of a scope if your eye sight starts to fail.
