Wednesday update

Not much today on a road trip will post tonight.

Shop Tuesday 10-8 fluting machine

We are working on all the components for the barrel fluting machine. This is the Master Cam video for the making of the lower base. This part allows the chuck plate to move in and out. This allows us to load and unload the barrels from the chuck.

This part has now been machined.

I will have a video of the machining process soon.

Working on the fluting press

This video is the first op on the back plate of the barrel fluting machine. In this video we are drilling and reaming the hole necessary to hold the plate to the table of the milling machine and align the plate for the next op. This will allow us to remove the exterior clamps and drill and ream all the holes necessary to attach all the components. Due to the size of the back plate the machining will be accomplished in phases. The lower section will be machined then the plate will be moved down and the upper section will be machined. This is not the most exciting video but one that allows us to accomplish a project using the equipment we have on hand. The other thing to keep in mind is the speed and rigidity of the machine. The max speed is aprox 2500 rpm vs the HAAS which will run at 12,000 rpm. The feed rate is also much less. So what would take the HAAS just minutes to accomplish will that this little cnc mill hours to finish.

hope you enjoy the video.

High speed photo’s

This is just a great series of photo’s from a high speed camera on the M-1 Garand.

Sunday answer for 10-5

The item on Saturday’s post.

Is a 22lr cartridge adapter for a MAS 36 training rifle. This is as it looks next to a 22lr cartridge.

This is with the 22lr cartridge in the adapter.

Next to the rifle.

In the magazine of the rifle.

You can see the special feed ramp for this caliber in the follower.

Here are a few pictures from Jean Huon’s book “Les Fusils Francais A Verrou” showing the cut away of the adapter and a black and white photo of the adapter.

If you don’t have Jean Huon series of books you should get them. Even if can not read French the pictures are well worth the price.

What is it Saturday October 4

video Friday October 3

I just found this video from DSA on making there FAL.

Enjoy the video.

Thursday”s post more on the fluting machine

After a 14 hour work day my energy level is in the toilet. We have been working on the fluting machine so here are a few pictures of the parts as they currently stand.

If I get home at a reasonable time tonight I will make a complete post on the parts and there relationship to the machine.

The metal used in firearms

I have been working on a post concerning the different types of metals used in weapons manufacturing. The start was when we did the post concerning the different types of brass and bronze used to make different parts of older weapons. I still have not completed the write up and have an interview with a metallurgist in the near future. However one of the sites that I visit very often has a good write up concerning the metals used in firearms. If you have not been to http://firearmshistory.blogspot.com/ you should go.

This are the three posts he has done and I found them very interesting.

And the latest installment is Metals used in firearms -3

Enjoy the site I do. Until tomorrow.
