Thanks.

I am more proud of how the overall gun turned out. I wish some of you guys could give it a run.

I think she picked out the Vixia something 40. It must be similar. It got a good CR review.

I made one last change early this morning and fired the final test target.

This was only a test fire, but I did shoot at a target. This was 900 rpm and 685 fps and is 30 rounds.



hmmmn. Shooting a little low!! :lol:

Really though, ....Nice!

You got the long chain connected to that pocket watch on that Zoot suit?? Pin stripe suit?? Shoes polished with "Blackola"??? Heh!, Heh! ---Cam

I always keep a combination of notes and plenty of pictures. I need to write up how to build an air machinegun from scratch and how to get it running.

The wife is looking at video cameras so I should have one pretty soon. I'm looking forward to it. I have my Zoot suit and cigar ready.

Look into the Canon Vixia HF M31 That's what I'm using right now... ---Cam

Re: TBK 2010 Airmachinegun

The last improvement turned out to have even better results. By lengthening the carrier, the spring tension went up. It needed a little adjustment so I snipped the a few coils off the spring. Just about, but not quite. So, I cut an o-ring groove for a full seal on the bolt body for more recocking force. Unbelievable recoil!! So, I went back to a full strength spring.

Even though the bolt weight is higher, the recocking sequence is now faster (about 65-70ms), so the rate of fire is about 900 rpm. It rips and gives a great recoil effect.

My additional testing showed that it is very reliable in all aspects. The cool thing is it feels very powerful with the recoil effect so it doesn't even feel like you are shooting an airgun.

The velocity is at 685 fps with daisy bbs through the 12" barrel.

Re: TBK 2010 Airmachinegun

One little set back. I am making the bolt "carrier" a little longer to resolve a slight conflict with the spring and sear. Just about done.

I am going to leave the weight a little higher and check the ROF. If above about 700 rpm then I will leave, otherwise I will lighten it back up for 800 + rpm.

Re: TBK 2010 Airmachinegun

Yes, it was somewhere around 800 rpm. I shot over the chrony just prior to the video to get the velocity, but didn't check the ROF again. In the video it sounds pretty fast, but I measured recently at 800rpm. I'll double check it.

Re: TBK 2010 Airmachinegun

Actually the tarp is a grill cover and it is leaning up against it and I took the pictures sideways.

It is shooting 675 fps which is right in the ballpark of what I wanted. That is through a short 12 or 13" Crosman 760 barrel, so the fit of Daisy bbs is not very good. Nice performance for that short barrel and full auto, though.

Tried to take a video with my regular camera, but don't know how it came out yet.

I see you painted the "shiny". Cool. Like your Dad said: "You could have left it unpainted....''

I would think ANYONE seeing that MUST be impressed! ...I am, can you tell? ---Cam

P.S. ..........You WILL make a video of that shooting!!!! You WILL!!

....Oh and the Zoysia grass is gonna take over your gun come spring! Is that why you have the tarp covering half the gun on the ground??!

...tell me, no one but a "Southern Boy" wouldn't know that grass in a photo!

It turned out even better than I imagined. I wasn't really trying for an exact scale model, but just a general sense of the Thompson. I had a few ideas along the way that got it to this point. It looks really good. There are still a few things I could still do, but decided to call this one done.
