Coaxial Hybrid

[noname]

Anyone ever made a coaxial hybrid? I would but I don't built any combustions or hybrids or anything.

I doubt anyone would ever try it. It is extremely dangerous, for a few reasons.

One, the barrel is in the combustion chamber, which could cause it to implode.

Secondly (and obviously the more significant reason) is that coaxials require modified bushings up near the end of the chamber (to allow the barrel to pass through). This is undoubtedly a very weak point compared to the other parts.

r u talking about one with a piston? it's possible.

[WOW!!]

Yea you could do it, and the part were the barrel goes though is better because it gives more glueing area.

[mark.f]

ANYTHING you modify could be a weak point.

[Brian the brain]

or...

anything YOU modify could be a weak point.

Put a buttload of screws at a slant inward to the barrel, and file the screws smooth inside the barrel. OR just make the whole thing out of metal.

[WOW!!]

So if I take some PVC pipe and mdify it in to a combustion cannon it is a weak point?

[Velocity]

yes it is a weak point. But because combustions do not generate THAT much pressure (102 PSI for propane under IDEAL conditions; usually its only around 40 PSI), so it is not a factor.

Hybrids, on the other hand, generate incredible pressure; people are worried about SCH 80 hybrids. If you modified a SCH 80 part, then it would become a weak point. Hybrids are much better at "exploiting" weak points than pneumatics (used at 100 PSI or less) and combustions

Coaxial hyrbrids have been made an used,i belive Rambo has made one and that is the next most used design apart form the burst disk hybrid.But i dont no what mix they have been taken to.
