Radius were added to the thumb [...]]]> 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.

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 [...]]]> 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 first print ,as always, [...]]]> 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.

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

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.

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.

It also dissembles and the stock comes off.

There was a print of it [...]]]> While doing research on the 1917 trench carbine I came across a rifle that I have never seen or even heard of. The V9000. There is a video on YouTube posted by LAI Publications. I just fell for this cute carbine.

It also dissembles and the stock comes off.

There was a print of it taken apart.

I thank LAI publications for posting about this rare and interesting weapon. I decided that I need one in my collection. There is no chance of buying one and it is full auto so actually making one that is exact is out of the question. However I can make a semi auto one. As with all of my projects I need to design it from scratch. With that in mind I have started just that, but I am making a few changes to the design. First I will make it in 9mm and not in 7.62×25 Mauser. Second, I am going to make it to use a different magazine. I have never been a fan of the Mauser style magazine. they are expensive, a number of the ones I have do no fit properly and they are hard to fine.

My favorite magazine for my Broomhandle projects is the Finnish M/20 smg magazine. They are available at Apex gun parts.

It is a great magazine that I will cut down to 25 rds.

The first step was to design the lower receiver to use a M/20 magazine. I started this process with using a cut Chinese Schnellfeuer lower.

I was able to make a basic solid model but with the proper dimensions for the M/20 magazine.

There is a number of features missing from this model but, it is just a starting point. So I printed it out on m Bambu P2S 3D printer.

I was able to check to see if my magazine housing was dimension properly, and it was.

The next print will have the magazine release button. The rear of the receiver needs to be corrected. the bottom of the receiver is to thick and it receiver needs to have  internal dimensions reduced. I am currently working on the second model receiver and should have it completed by the end of next weekend. I also need to add the dove tail slot in the front of the receiver
