Looks promissing, good to see you finally starting to explore hybrids!
When I think about it after seeing your mini I got an idea that might allow pretty quick burst disk change but still keep the small size.
I'll order some more brass pipes and see if I can mock something up.
I don't know if you saw my mini hybrid but I fired some .22lr bullets from a realistic barrel length at 5x and the projectile did penetrate quite deep into wood despite the low mix and short barrel.
A small hybrid at 20x should manage to provide the power of a .22 rifle.
If you rifle your barrel and add a sight you have a nice little plinker.
Good luck on all your future hybrids

A bigger hybrid , say 1/2" diameter barrel with a .22" projectile saboted to 1/2" will do the same at 5x though...

HGDT suggests that 12-15X would be enough to match the power of .22lr
@CpTn_lAw
that will almost always work but is it really worth the effort ??
I don't know what do you think of it but something tells me that high mix smallbore hybrids are the future of spudguns

Absolutely, I would personally like to see a high mix big bore hybrid other then those I have seen though.
A fridge compressor, a few hydraulic fittings and a sleeved brass barrel makes one FINE stock mounted rifle IMO.

Even though this is deviating from the thread, I'll contribute my $.02 briefly. I am curious to see how long it takes until people start building higher mix (10-15x) handheld hybrids. SB15 already fires his at 8x handheld, and that's with a galvanized iron gun.
What I'd like to do is machine a small chamber (1" Diameterx 3 or 4" length) out of steel designed to handle 15x comfortably enough that I would feel safe handfiring it.

Off topic you guys are
Well, I'll join in with one post:

I have been thinking about something that will fit that description.
When Larda was machining my hybrid chamber I decided to have a larger chamber instead of the 3"ID hydraulic tube sleeved in a slightly larger hydraulic tube. I started thinking about it and that chamber is absolutely perfect to make a 20x handheld hybrid.
And you know what he said when I asked for it? He has the same plans for it himself, that means it will probably be done by one of us sometime in the future:D

I doubt it. Interest in hybrid launchers has seen its peaks over the years, but the technology is too complicated
yeah, it is complicated but thx to the law of diminishing returns pneumatics are a dead end (well at least if you want MOAR powah.... and definitely if you want moar from a small bore launcher)
a 12X hybrid can achieve the same power you can get with a 2000psi pneumatic (I know it is very general as I haven't mentioned the calibre, barrel length etc. but I hope you get the idea of)
Basically speaking to get 2 times the ME of a 600 psi gun I'd have to increase the pressure by 4 times. So I concluded that I might as well build a hybrid to get 4 times more power with a 15X mix
@spudfarm
I am more interested in his semi hybrid

Any progress? it's been a few days
as fer sealing it:
I'd think you can inset the epoxy holding the BB and tubing, and pour silicone into it, i make O rings and things from that stuff occasionally, using methods similar to this:

you could also use tire tube rubber or whatever you make piston seals out of

My reply seems to have disappeared (had you got the PM I sent you before the great spudfiles collapse of 08/10?)
Ah well, previous project temporarily suspended for geographical reasons

I'm giving the cartridges a break for now in order to work on the sentry gun BBMG as it's been languishing on the shelf for too long.

yeah, I got it...
I like redheads, don't you remember??
on the sentry gun BBMG
I am sure you can do both...
you know, I am not talking about the hybrid catridge, right ? : D

Any server problem where there's an almost perfect backup available is not a "great collapse".

I've been on forums which had to be repopulated from the ground up following a server crash - and even then, on one of those sites, it took several weeks to get the site online again at all, so quite a lot of members were lost along the way (although most of the regulars stayed).
