I've successfully used an acetylene regulator, but I'm no expert. You
can also get cheaper regulators specifically made for propane.

I've recently been through all this.  In fact, I am right in the 
middle of a substantial college course on cutting and welding.  One
thing that is often overlooked is it is the oxygen jet that does
the cutting.  One can use any fuel gas at all to do the heating.

On the cutting table at school we use proplyene, acetylene, propane
or chemtane.  

Sure, you can use an acetylene regulator, but you can also use an
inexpensive 'barbeque' regulator.  

What are your price constraints?

Hello everybody,
I dont know a darned thing about metalworking, unfortunately, but
what I want to do is bend a piece of sheet metal into a box shape
with a flange on the bottom for attaching a screen across the base.
Is there some kind of  tool I can get to help me make nice right angle 
bends, or should I not even try and do it myself?

Thanks in advance for any replies. If anyone does happen to reply, 
here's my email address: [email-masked]

I do not know about cutting with propane, but I have been melting and soldering, gold, 
silver and platinum with it for many years.  I have been using an acetylene regulator 
for a long time.

Please note however, that propane is in the tank in the form of a luiquid, with a little 
bit of propane gas on top of it.  The bottle pressure on the regulator will ALWAYS BE 
THE SAME, no matter if the tank in newly filled or always empty, since the regulator can 
only measure the pressure of the gas that "sits" on top of the liquid.  You can however 
set the working pressure to whatever your needs may be.

Do not get a cheap "propane regulator".  On one of these one can not set the working 
pressure accurately.

An acetylene regulator will work just fine. What you will need is a
cutting tip specifically designed for cutting with propane fuel gas. The
arrangement of the preheat ports is altered as is the size. The design is
different to accomodate the difference in heating value in the fuel gas.
BTW cutting with propane leaves a cleaner edge with less slag and is
commonly done in industry.

One thing worth adding here is that the burning of propane releases a
lot of water vapor.  I learned that from a previous poster (see, I can
be taught).  

So either do it where there is plenty of ventilation or be prepared to
scrape rust off the ways.

An acetylene regulator works fine.  You will need an adapter for the tank.
I have been using this sort of rig for 20 years.

  I don't know where I saw it but I seem to remember that a lot of water
vapor is released by burning acetylene as well. In fact I think that
burning just about any hydrocarbon will create water vapor.

Quality is like buying oats,
        if you want nice, clean, fresh oats you must pay a fair price.

However, 
        if you can be satisfied with oats that have already been through
the horse...
                          
That comes a little cheaper...

Here's my question:

If (as others have posted) it's OK to run propane through an acetylene
regulator, how come the welding supply outfits sell separate
regulators for the two? I've been thinking of making a change in fuel
gas for a while now, and this question's been bothering me.

  To be honest I don't know. Although it wouldn't suprise me to much if
they do it just to sell another regulator. What I do know is that when I
first got my torch I used propane for several years before switching to
acetelyne. I had no problems and I'm still using the same regulator 20
years later.
