A progress report from a few years ago. The dark side had become all-consuming by this time. There was no turning back.

I love it Lloyd, brilliance in action. 8)
Funny where these high powered AG's were 200 years ago, and then they disappeared, now they are back and with refinements that equal a powder gun in so many respects, your prototype is the equivelent to a .22LR anyday of the week. Great vid Lloyd. J

Thanks Jeff.
I was kind of surprised at the results this thing produced.

Cool...Any more videos? I watch all the airgun vids I can on youtube...and I wanna see pics of your current projects.. especially the prototype disco
-
Lloyd.... that is REALLY cool.... I was trying to read the pressure remaining on the gauge and it looks like about 2000 psi after the shot, is that correct?.... How big was the valve/reservoir used in those shots?.... I'm trying to get a handle on the (in)efficiency of those velocities.... ;D

Hey City,
Glad you enjoyed the video!
I have another video that I am going to put on the Big Bore gate in a week or two. It will be another garage session and I know that some folks will find it very interesting.
I hadn't planned on doing anything with the disco because all of the ideas are borrowed from other folks, many of them on this forum. I just did them to my gun, and they worked there too! Thanks to everyone who has shared so freely !!
This video and the big bore one I've got coming are about 100% new.

Hey Bob,
That valve timing was set up for max power and was disgustingly wasteful. The video was made 3 years ago and I was still learning ( I still learn something every day!) The tank was 262 cc, so to totally fill the 24" barrel would drop the tank pressure from 3000 psi to about 2,786 psi (214psi drop). This was operating pretty much as a dump valve to get those power levels. I could have used 1/3 less air (142 psi drop)and only lost about 7% of the power.
Oh, and the valve was ........BIG.
For the upcoming big bore video I will have power AND efficiency.

Lloyd thanks again for sharing your knowledge, time and love for the sport of AG's. Post like these are priceless learning tools. I know the membership sure appreciate it. You and rsterne, share allot of your knowledge. And I thank you...

Great stuff Lloyd!
-
Lloyd, what was ringing after each shot? Reservoir? Barrel?

Gene,
Thanks for the kind words, and for making the GTA what it is: a fun and comfortable place to exchange airgun ideas. ;)
dk,
you bet ! ;D
Charles,
The ringing after each shot is from the steel bullet trap. It's welded up out of 1/2" plate and weighs about 300 pounds. :-[

Great Comparisons of pellets and air Lloyd. Thanks
-
Great video Lloyd! Thanks, can't wait for the new one.
-
Man those babies sure were getting it. Very nice work. I enjoyed it very much. 2nd pellet 2nd shot man did it get an encrease in vel & energy as well as the lighter wt pellets you were using to test. Again nice job...
-
Gents,
Thanks for watching the video. It's always nice when something actually works like you hoped it would. It's even better when there are other folks around who appreciate it.
Thanks,
Lloyd
