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.

DSC_0272_swHere 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.

spencer0001scIf 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.

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.

DSC_0237_sIf 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.

More Japanese 99 magazine update. 9-30

We have finished the second op die for the Japanese 99 magazine right side. The die is complete and the springs and pins added. This is a photo  run down of the final die. This is the complete die assembly

Monday update 9-29

The 1″ steel plate that we cut up last weekend has been cut down to size and then sized in the HAAS to actual specs.

DSC_0145_sThis is all that is that is remaining of the steel sheet that we started with.

DSC_0180_s

All of this material will be used on the fluting machine.This is what it looked like after its time in the HAAS and sized.

DSC_0173_s

DSC_0176_sI also had a piece of rough ground stock that is the correct size for the chuck backing plate.

DSC_0177_sA quick look at the chuck backing plate solid modelchuck subplate 2

chuck subplate 1.

 

The major back piece which is 9″ wide and 48″ long is cut over size and set on the 3 axis cnc mill.

DSC_0171_sWe did a basic mark up on the plate to show where the initial bolt hole and reamed dowel pin holes are going. Then it was time to place the blocks under the plate and clamp it down. This first set up is just for drilling 6 holes.

The design has been changed to allow it to be held and located easier.

flutting machine final 3This is the new back plate design.

broaching machine backing plate revised 1

We moved the bolts that attach the fluting press to the side of the hydraulic forging press closer together then we will also machine 3 reamed holes in it as well. The reason for moving the bolt holes together is that corresponds with the table on the cnc mill. Now with this design I can machine the 6 holes and 3 reamer holes as a first op. then bolt the plate directly to the table of the mill and machine the sides and drill, ream and tape the rest of the holes without fear of movement.

Most of Sunday was spent doing honey do’s  The fixtures are in place in the hall bathroom and it is ready for use again. A few small things left to do, but that is for another weekend.

DSC_0213_sLast night a heavy rain storm came through the valley.

DSC_0191+s

This is a quick video of the storm.

In it’s wake it left 1″ or so of rain. That brings the total to 6″ for the last month.

DSC_0208_swMy little rain gauge.

The project for the rest of Sunday is to build a new gun rack for my gun room. This is the solid model.

4 FT GUN RACKIt is 4 foot across and will hold 15 rifles. Here is where it is going in the room.

DSC_0214_sThis is as far as I got today. It is 5pm and time to relax a bit and I will finish it off next weekend.

DSC_0211_sThat is it for the weekend update. Until Tuesday.

 

Sunday answer September 28

This is the op rod for the MP-44. It is a combination of the gas piston and the bolt carrier. The bolt carrier provides the  cam surface for the bolt to lock and unlock the bolt from the trunnion.
