Oxy-Gasoline Cutting Torch

[rangerman]

Five gallons of gasoline in a sealed container will yield maybe the same power as a stick of dynamite only IF it's liberated and allowed to mix with oxygen/air in the presence of heat.

In fact, the total amount can't even explode until thoroughly vaporized and mixed with the right proportion of oxygen or air.

We see exploding cars in movies when the gasoline leaks even in small amounts, but then that's only in movies!

5 gallons of gasoline equal 1 stick of dynamite ?
I would guess maybe a quart of gasoline will = the power of 1 stick of dynamite BUT I am guessing

Try MAPP Gas ( Propolyne) it burns hotter than propane, cheaper than acetylene , you'll probably have to change the tips.

Are you sure that's real MAPP (methylacetylene-propadiene propane) and not high-propylene LPG?

Boy, putting gasoline under pressure and then mixing it with oxygen and setting fire to it just gives me a cold chill up the spine. Is this for real? 5 gallons of gas in a sealed container yields the same destruction as 1 stick of dynamite.
Tell me I'm wrong and don't know how it is done safely.

Oddly enough I can confidently say "You're wrong". Talk to your local fire and rescue crew. Certainly in Australia they have at least heard of (and lots own) petrogen units for rescue work. No hassle of Acetylene and you can put the whole thing with a small oxy bottle in a back-pack to take anywhere.

I'm not sure how you could possibly think petrol (your gasoline) is anywhere as fragile or dangerous as Acetylene.

I'll stick to acetylene!

never used anything but propane whole lot cheaper than oxygen i use 25 lb exchange tank need propane tip and adapter for gauge whole lot cheaper and easier for me

I am not sure where he is wrong except one gallon of gas equals 10 sticks of dynamite all though Acetylene is very unstabile the way it is filled and packaged is much safer than dumping gas into a can yourself and putting it under pressure. I would not want to be near either in a fire but there are more safety checks in a pre-filled acetylene cylinder. Ray

Really, Thats It? A thread adaptor and I'm good to go? That's awesome.

Make sure your hoses are rated for multiple fuels. I understand the regular ones will degrade over time if you run propane through them. The gauge may not even need an adapter. I use mine on my BBQ tank when I'm low on acetylene or if I just want to do light work. The gauge has both types of threads. You can't go in the other direction because the LP reg will allow too high of a pressure to be used with acet (or something like that.)

It's building bikes via brazing, but this is a great thread on acet vs. lp: http://www.velocipedesalon.com/forum/f10/acetylene-vs-propane-30480.html
Topics covered are tips and sizes, and even stealing grandma's oxygen concentrator for the oxy side.

I've got to admit I don't get that warm fussy feeling. Gasoline is an oil, oil and oxygen cause great explosions that's the first thing you learn in a welding course is NO OIL NEAR the gauges. If it works that's great but I'd be darn leary of it.
If you do a lot of cutting they use liquid oxygen to cut with we used that from 12"-16" molder tie bars.
