At princess auto for all you canucks.

I picked one up on friday but haven't had a chance to try it out yet. I'll let you know how it works as soon as I get a chance (hopefully tonight).

Anyway this thing is basically a portable and instantly and safely built propane forge.

It'll run up to 500,000 btu. It takes a minimum 20 pound tank of propane (barbeque size) and said 20 pound tank will run it for about 2 hours straight according to the listed consumption.

The tip is about 2" across so it's gonna be a pretty big flame.

Anyway it's on sale now for $64 CDN at princess auto.

Also if anyone's used one of these things before or knows what the heck a btu is feel free to chime in.

Its "something termal units" I believe. Substitute "something" for the word that starts with a B.
I wonder if that have them here in the U.S.? Do you have a the makers name and model number? I'd like to check that out.

I think btu = British Thermal Unit if any one has a chemisrty text book it should have an explination of them and a conversion to whatever you understand best.

A BTU, or British Thermal Unit is a unit of energy. Unfortunately, I am aware of at least 3 definitions of the BTU - the International, the US, and the "Therm". They are all fairly close to each other, and can probably be used interchangeably unless high precision is required.

1 BTU (US)= 1054.804 Joules = 251.94 Calories

Again, there are at least 3 kinds of calories (International, 15deg C, and therm. All are very close together.

Tiger Torch. I've never thought of using one for a forge component, but I do know they throw lots of nice heat. To give you an idea of the heat that they will generate, take one frozen Caterpillar (bulldozer) @ -30 degrees Centrigrade. Cover with a parachute, throw a Tiger Torch under the Cat under the stump pans away from any oil leaks or drips... Come back in 18-24 hrs, to find a nicely thawed heavy chunk of solid steel which is much nicer to work on when your hands aren't freezing to everything otherwise.
BTU's, hmmmm, I'm too tired and groggy to try explain it clearly, so I'll let someone else explain.

Look around the keenjunk site, I think there are descriptions of a forge built with said torch.. They call them "weedburner" forges. I picked up the same torch for $20 U.S. from Harbor Frieght.

Horsefriend, and everyone else out there...

That propane torch kit from HF, despite it's potential as a sweet deal, has recall info on the HF site.

I don't know why they still offer them for sale, but it's sounds not quite so good.

If memory serves, a BTU is the amount of energy needed to raise 1 pound of water 1 degree F (at sea level). It's the English analog to a calorie -- the amount of energy needed to raise 1 gram of water 1 degree C.

Since there are 454 grams per pound, and 1.8 degrees F to each degree C, you can convert BTUs to calories<ul>
calories = BTU * 454 / 1.8
[/list]

This gives that a BTU is equal to 252.22222 calories. I don't know nothin' bout no other BTU scales.

I believe it (BTU) is the energy required to raise 1 gallon 1 degree, But I could be wrong, college was a long time ago.

Ragnar

yup... 1 BTU = One gallon of water raised 1° F... I consulted the Bible (Machinery's Handbook) to make sure...
