... and my penguns
The basic idea is to have a "universal" pistol grip and ignitor setup that you can attach to the chamber via the schrader thread, with the ignitor accessible because piezos tend to wear out eventially.

Hmm... interesting. I like the idea of being able to swap out different launcher designs... I can't wait to get home and back to building again.

I think the key is to make things modular. I don't see the point of putting the effort into finishing a launcher that might screw up internally and cannot be repaired.

Exactly. Modularity (is that even a word) is extremely useful in developing a testbed actual gun.. but still easy to prototype something.
I actually wanna bounce an idea off of you-- I've been thinking. if you put two thick rubber washers into the union- you may be able to make an almost bolt action out of it. If you add a handle to the lug, then you can just turn it possibly a quarter-half turn, and then possibly move it forward so the handle locks in place. That way, it makes the gun more "gun-like", and saves a bit of hassle of threading a union.
What do you think?

... a sort of "bolt action cam-lock"? It could work, provided the handle was long enough to provide enough leverage for a tight lock.

Exactly.. that's pretty much what I had in mind. i don't see why it wouldn't work- yea you'd have to be able to get some leverage, but it would make the action of reloading a bit more like a gun, and easier in that you don't have to thread the union all the way.
If you could get it to only need a quarter or a half turn, it could easily be similar to many bolt actions out there today.
This comes to mind- http://www.thefirearmblog.com/blog/2009 ... mg-pistol/

Bahahah thats awesome.. WHy are they dressed like that? For comedic effect?
but on a related note- do you think the idea is plausible?

Yes, it's a segment from a longer clipJDP12 wrote:Bahahah thats awesome.. WHy are they dressed like that? For comedic effect?
Yes - cam-locks work, and this is simply the same idea with different geometry.but on a related note- do you think the idea is plausible?

You could possibly add a second lever to both minimize the stress on the single lever but mainly provide an equally tight grip on each side of the bolt/camlock mechanism.
The second lever wouldn't even have to stick out

WOW WOW WOW WOW WOW! :bounce:jackssmirkingrevenge wrote:Update on the suppressor, the epoxy cured quicker than I expected so I've been doing some testing.
It's not exactly "mouse fart" effective, but it certainly takes the edge off the muzzle crack and the noise is a lot more tolerable. I did some chrony tests at various mixes too, first a video of a shot at 10x to show chrony reading and some indication of noise, target was a folded up towel so there should be little projectile impact noise.
[youtube][/youtube]
Here's some data for 16 grain 0.22" pellets showing mix - velocity - muzzle energy:
8x - 840 fps - 25.1 ft/lbs
9x - 879 fps - 27.4 ft/lbs
10x - 925 fps - 30.4 ft/lbs
12x - 983 fps - 34.3 ft/lbs
14x - 991 fps - 34.8 ft/lbs
Yes, I got first click ignition at 14x I have to say that I wasn't expecting successful piezo ignition at such high mixes after CpTn_lAw's 8x limit data, but it works
The relatively small gain in velocity between 12x and 14x suggests that a stronger disk is needed to see more benefit. Two disks held at 10x but will probably fail at 14x, we'll see...
edit: Yes, 14x will burst a double disk I'll try and get a chrony reading.
Here's the (roughly sanded) suppressor, chamber and ignitor setup:
Excellent experimental information. It helps me a lot to have a real reference in my designs.

Yes, I can make my measurements However, the tests you performed give a frame of reference regarding the volume of the combustion chamber, in relation to caliber .22, .177, barrel length, mix pressure, ammunition speeds and damage in the objective, apart from the possibilities and problems of the piezoelectric ignition for these conditions, which is what I am using. As I said earlier, a practical basis to design from there.
It would be very good to gather these data in a single image, because they are scattered throughout the post and it is quite long. But also, with a little time, you can extract the info from the numbers and comments. always I have understood that science, (of the spud or in the field that is), NOT born with oneself, that's why you have to investigate what has already been done and learn it.
For example, I, based on this work, I have planned to reduce the volume of my combustion chamber to 20ml, (I am currently using about 30 ml). The result is that more pumping cycles are added unnecessarily, to compress my mix. Aside, raise the compression of the mix to at least 10 or 12x, which is where "music begins" for this type of mini hybrid, so I could read here. It may be necessary, to make more accurate all this information, the percentage of gas used in the mixtures. I am using a slightly rich mixture, based on the experimental results of jimmy101. Of course, the fundamental is complete.
