I don't think a propane tank is safe at those pressures. LPG doesn't get much above like, 120psi unless the tank gets hot, as far as I know. I don't think they're rated to more than a few hundred PSI, so using one with a fridge compressor could result in some bad juju (shrapnel, etc...). Can't help ...

@Grignacke, I know charging gung-ho into hybrids seems like a lot of fun, but it's really a good idea to build a few combustions and pneumatics first, and spend LOTS of time reading up on the operating principals, construction, and safety of hybrids before building one. With combustions and (most) p...

@GunFreak: Good idea on the coupler for the chamber pipe, that will probably work. I'll check and see how much they are next time I go by the plumbing supply spot. I don't like the idea of sliding 2" sch80 over the 1.5" SDR21 for a breech loader - it would leak like mad and reduce the amount of air ...

Thanks in advance to anyone who might take a few minutes to answer a couple of questions for me. Background: A couple of summers ago, I build a large pneumatic with a 10' stick of 4" PVC for chamber and 10' of 1.5"SDR21 sleeved in 2"SCH80 for barrel, over-under style. It was massive, hard to move ar...

A cleanout cap is probably the easiest way to access the chamber, but it makes venting between shots more difficult (as opposed to the ball valve in the design, which makes venting the chamber very easy).

You know this is a several year old thread, right?

Peace,

By the way, Zaria, I'd have to say I have a 1-up on your gun there. (2-up, actually.) When I shoot ESP, I use an STI Eagle 5.0 double stack. When I shoot .45, I shoot a Thunder Ranch stainless 1911. :P Good stuff. I like STI's, although a single-stack fits my hand better. I shoot some IDPA, but no ...

It's quite a Rube Goldberg invention, but I like the humor of the concept.

Hmm... How could we build one to make curly fries?

Peace,
Pete Zaria.

I can't condone putting holes through PVC pipe (for your burst disk holder system) and then using it as a hybrid cannon... Heck, I say never put a hole through PVC except where fitting and pipe overlap, and even then, I try to avoid it. If you do this, test fire it remotely several times first... I ...

Your opinions were appreciated - this thread has now been deleted.

sorry there a 3 questions 1. is it possible to use a pure oxygen and propane mix in a hybrid cannon 2. what ratio of oxygen and propane would need to achived for it to detonate. 3. what type of material would be most suitible for the job 1. Of course it's possible. However, using an oxygen-enriched...

Ah, good news! I bled the air from the power steering system today and the noise seems to have gone away.

I just went out and drifted a couple of corners in the rain to make sure - so far so good. I'll report back if I have farther problems. Thanks for your time, guys

Peace,

Not having power steering makes it a tone of fun... I bet it is coincidence you check the standard things like the fluid and the belt? What kind of power steering is it...rack and pinion or something else... It would make sense the rmps would increase since it take more power for engine to run the ...

Turning up the radio is an option... Bigger exhaust is a better option :) Peace, Pete Zaria. That's the spirit! :D :pirate: Good luck mate. Nah mate, if he was a real man, he'd harden the f*** up! and remove the power steering altogether :wink: OK, I've removed the power steering from a Ford Ranger...

I'm beginning to wonder if it's completely coincidental that the power steering issue started at the same time I modified the air box. Peace Pete Zaria. That was my first thought, however if you do the math (In your head, no calculator needed) it tells me that it *must* be attributed to your modify...

I'm beginning to wonder if it's completely coincidental that the power steering issue started at the same time I modified the air box. A good friend of mine who's in his second year of mechanic school is going to take a look at it for me Sunday, so I'll report back what I find out then. If anyone ha...
