Eather is more powerfull, but a metered propane system would be better. However, considering that eather is a gas... METERED EATHER system!

the max combustion will be only around 50 PSI, so yeah both would be fine as long as you use PW pipe and solvent weld your fittings on

Yep, it'll be fine, as long as you don't go messing with oxidizers like oxygen....
If you do that, you're asking for serious injuries.

yah one of the kids my cousin goes to school with decided to try using acetelene/oxygen mix in his new combustion(he had only used pneumatic before that) he ended up in the ER getting pvc shrapnel removed from his stomach :x :x ouch! so i would stick with ether or propane or butane if i were u so u dont die

well, yeah it was his first combustion and he wasn't experinced enough to know that acetlene would generate so much pressure. so i wouldn't recomend messing around with dangerous toys if ur not experinced in the matter

Well the acetlyene/oxy mix doesnt create too much pressure, its how it creates it. Propane deflagrates, a steady burn over the entire mix. Oxy/Acetylene detonates, an enormus pressure spike followed by a less powerrful burn. Its the same as high explosives compared to low explosives.

And rsgpit's explanation is why it shattered. PVC just can't handle the pressure spike. That kid is lucky that DDT didn't occur, otherwise someone would have already read his eulogy by now.

either is deffently more explosive, just as sure as my spelling is bad ! used in proper quanity it could be awsume ! size = cost, a can of starting fluid is about the same or less then a can of rite gaurd, and you don't have to use no where near the amout of fuel to get the same power-so metered either a real winner if done rite !!!

P.S.- any lab rats out there willing to try it keep us posted

P.S.S - I AM NOT REASPONSEABLE FOR ANYONE TRYING THIS NOR AM I RECAMENDING IT !!! BE WARNED THIS IS VERY DANGEROUS, AS ALL CUMBUSTABLES ARE!!!

While it is true that ether is a non-polar solvent, it's also extreamly votile (boiling point <35*C... boils in your hand!) and the small amount you do inject will have a short residence time.
...in short, I'm saying it probably won't dissolve your chamber to any noticable degree.

Just so ya know, it's spelled spelled. :P

But yeah, there are a lot of people, even mods, who apparently don't know how to even spell ether. (And I thought the Spudtech Forums were bad with grammar!)
