Shop Update- The CNC Router

This is a saga of the CNC router. The router was built here in the shop and it was used to make the stock and handguards for the VG1-5. 5 years ago I was running a batch of parts and hit an over travel stop. When this happen I just shut off the machine as […]

The Mauser 1917 trench carbine receiver

I have reverse engineered most the lower receiver in Fusion 360 and will print the first model this week. This is the first print so I can test my solid model. Using the Bambu P2S printer I will print a 3D model. There are a number of modifications that will needed to be made, but […]

More on the Sudanese AR-10

With the last test model machined I started putting the lower together and a number of issues were noted. The receiver dimension is correct for the holes, magazine release, magazine well and overall length and width. the magazine button and release lever are not deep enough.

These are the noted problems.

The first one is […]

OP. 4 on the Sudanese AR-10 lower

The 4th op is to thread the rear of the receiver for the buffer tub and to drill the hole for the rear take down detent pin and spring and the stock alignment hole. The holes were first cut to the proper size then a thread mill with the proper pitch.

threaded the correct […]

Mauser V9000 trench rifle

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 […]

1917 trench carbine 3D prints

With the new Bambu P2S printer here I decided to start printing out some of the components of the 1917 trench carbine to verify the design and measurements.

The first part that I printed out and checked is the fire control group. I Then used Bambu studio to do a slicing program on it. It […]

Why it is necessary to run a test part after changes to the program

A number of changes were made to the Sudanese AR-10 lower receiver. Selector stops were added and a new profiling program was used to allow for a better finish around a few areas of the receiver. Then a second lower was machined out of 6061 to verify the changes. During the process of machining a […]

More work on the 1917 Mauser trench carbine

In this post I am going to chat about a single part. The Lock frame stop. This individual part is common only to the carbine. The take down lever. you can see it here in this photo that I found on line.

This is the part in question.

Here are the patent drawings that I […]

1917 Mauser trench carbine

This Project is definitely interesting one. By using a combination of engineered drawings, pictures and C96 parts to measure I have been able to get a reasonable set of solid models. I started on the lower receiver but it did not take long before I realized the the fire control group holds the key to […]

Machining the Sudanese lower receiver op.2 and op3

With op 1 completed it is now time to work on op 2 and 3. First a fixture needed to be machined to hold the machined receiver to all finishing the other side.

The machined op1 piece was set in the fixture and tighten down

All the holes were drilled in op1 so now the […]
