We are now taking reservations for out reproduction VG1-5 rifles! Price is $4000, and they will be ready to ship once ATF gives final approval on the design. The get on the priority list, contact Matt or Greg at Allegheny Arsenal – (814) 362-2642. No payment will be taken until the guns are ready to ship.

Working on projects

I have found that projects are never easy or straight forward.

This is a common example for around the shop. I am working on a single shot rifle in 218 bee and 22 hornet. I like both calibers for fun target shooting and minimum recoil.

The design work is finished but there is a small issue and that is the steel. I have it but it is a large sheet.

So to move this slab of steel to the cutting table and cut with the track cutter. I need to use the forklift, which by the way is not working.

I bought it from a friend (?). who had jury rigged the hydraulic system to get it to move. Once I realized why it would no longer work it was time to start repairs. They had removed the generator and replaced it with an alternator but this left no room for the new hydraulic pump, so to solve that issue they removed the oil reservoir and turned the pump sideways and connected a hose with a check valve that he filled with oil long enough of the forklift to move off the trailer. Now on to the repairs. To fix the forklift I needed to make new brackets and weld supports in the forklift to mount them. To do this I needed to fix the portable welder.

The welder needed a new fuel pump, filter and carburetor rebuilt. With the welder repaired the bracket supports were welded in. The new brackets were design, fabricated and welded in my fab shop.

Once installed the pump and alternator were installed and the next set of issues discovered, lack of space. the brackets were then modified again and re-installed. The belt pulleys needed to be adjusted for proper alignment.

It was at this moment that the hydraulic hose and pipe might rub against the alternator and a clamping system was installed to hold the pipe back.

This now leads us to yesterday, after everything was mounted and getting ready for belts it was noted that the adjustment arm would not work properly. It was not long enough. A new arm was design in Fusion 360.

Then Fusion was used to write a program to cut it out on the cnc plasma cutter.

But to use the plasma cutter I needed to fix the coolant system which had developed a leak on one of the tanks.

With the leak located and fixed on the plasma cutter. The program was installed and

by the end of the day the new adjustment arm was cut out

bent to the proper angle and installed on the forklift.

It was for all intents and purposes a really good day. Now on to the next issue that needs to be addressed.

So when someone makes a really stupid comment like why is something not finished because it should only have taken 10 minutes I just smile and tell them to fuck off.

More on the V-9000 stock metal

The previous solid model that was printed showed some issues and missing features. I corrected the solid model and missing features. The push button assembly openings were added to the model as was the notch for the take down lever. I also corrected the the slot dimensions and shape.

Radius were added to the thumb protector portion.

This is the printed portion, as printed on my Bambu P2S.

With all the supports removed this is how it looks.

I still have a dimension to change for the length of the attaching slot.

Working on the V-9000 slide

With the receiver coming along nicely, still some changes need to be made, I started on the slide. With this carbine the slide is different then a typical C96.

This is the V-9000

vs the C96

The front of the slide is rounded and not angled and it is shorter.

I also want to make the front of the slide slightly longer for better barrel to slide engagement.

The first 3D print did not go well and pointed out some serious issues.

There was not enough material for the slide rails was the major issue.

The second 3D print corrected the missing material and by printing t a different angle came out reasonable well.

I still need to correct some issues. I need to change the size and shape of the slots for the rails, the firing pin block hole needs to be changed, I need to add material on the bottom of the slide under the barrel and I think I need to lengthen the rails. my next print will determine this.

A new 3D print of the lower receiver #11

I have more changes to the lower receiver. To help study the internal fit up I have enlarged the hole of the cut away slot.

I can actually see now that the trigger slot in the trigger guard needs to be longer and the trigger pivot pin needs to be dimensional changed and the stock adapter needs to be modified to allow proper fit up the the stock metal. The locking slot for the fire control group needs to be lengthen.

Over all the lower is real close.

The fire control group fits real nice ,the slide fits and once I correct the locking slot and stock attachment fittings it will be ready.

The V-9000 stock metal

With a slight break in modeling the receiver I decided to work on the metal that connects the stock to the frame. Between the pictures that are available and a stock for the Federal Ordnance carbine I was able to get a decent idea to allow for a solid model.

The first print ,as always, some dimensional errors, but not many.

This is the first print.

Changes have been made to the solid model on the height and metal to stock fit. I still need to change the slot dimensions, but the next test print is in model form now.

Still more on the V-9000 Broomhandle Mauser

With this photo you can see the progress on the V-9000 receiver. With each 3D print measurements have been corrected and the final product is getting closer.

With the 9th and 10th 3D prints I am doing receivers with sections cut away to allow inspection of the internal part fit up.

It allows me to verify the fit between the receiver and the fire control group and then make the corrections.

The V-9000 Mauser broom handle update.

I have been working on this project off and on with some major improvements to the solid model. Between surgery, some physical ailments, a small vacation and work it has been slower then I like. I am currently at version 10 on the solid model and my 7th printing.

This printing of the V-9000 is version 5.

This is a side view. The problems noted were the slide rail does not go all the way to the front of the receiver.

Same receiver and you can see that the magazine is still a little tight.

The fire control group not enters but the receiver is still a little long.

Another view showing that the fire control group does not come all the way up to the magazine housing.These are all minor changes that allow me to correct the receiver dimensions

More work on the V9000 lower receiver

After I completed the first 3D print of the V9000 lower

I notice some changes that needed to be accomplished. In fact I noticed a lot of changes that needed to be made to my solid model. some of the changes are inside dimensions and some are over all dimensions. In this case on the first print the fire control housing would not fit properly into the receiver. The walls were to thin and to far apart and the length of the receiver was not correct.

The good news is that the magazine well is correct if tight.

The second print corrected a few of the items. A radius was added between the magazine housing and the side of the fire control receiver.

The internal dimensions and wall thickness was corrected.

The hole for the magazine release was added.

With this print completed it is time to update the solid model.

Installing the cnc router boot.

Through out the design of the cnc router boot I wanted it to be easly removable to allow for tool touch off and replacement. The only easy way to do that is with magnets. I used the second test piece that I had added cardboard spacers and then magnets that I epoxy on to the router housing frame.
