As always, I am experimenting and testing theories.
I have
learned that acetylene has a higher flame temp but less BTU's than LP
gasses (propane, butane, natural gas). I find the results I get with my
blazer torch (butane) to be "better" than with my acetylene/room air
torch. I get less burned glue, less burned lacquer, and I find the
working time with pads to be more to my liking.
My question is
if anyone knows of a natural gas torch--basically a bunsen burner with
a handle. I know natural gas has its limitations but for the cost
compared to other fuels I am leaning towards having a city gas line run
into my shop.

I don't have much firsthand info, but I do know that the guys at Badger
State (Elkhorn,WI) who do the most soldering use natural gas/compressed
air torches. There's two lines running to the torch, one for the
natural gas and one for the compressed air and they mix it almost like
you would oxy/acetylene.
I've been using either a propane torch or a
Blazer for soldering, but am thinking of getting an acetylene/air torch
because I have occasional need to do brazing which requires a higher
temp than I can currently attain. I think I can do brazing with
acetylene/air torch if I use a #3 tip.

I studied at Badger. Since I don't spend whole days just soldering on
mostly bare metal, I don't think the NG and compressed air would be a
good match at my shop. I did think they worked quite well in the mount
department. I do almost everything with a softflame acetylene torch
like the guys in the reed assembly area use. It's small enough for pad
work or hot enough to braze keys and such. I will occasionally use a
portable porpane plumbing torch for things such as unsoldering large
horns.

Ferree lists a couple
of bunsen style burners; none with a handle like a regular torch
though. I don't have any first hand experiance using these.

Red Wing Technical School uses natural gas torches. Ask John Huth about
where to obtain them. I find that it take some practice, but I can do a
fine job with the torch I'm most familiar with. Right now I use MAPP
gas.

For woodwinds I use butane or a pad cup heater, for soldering I
normally use MAPP gas, and I've considered getting an oxy/MAPP torch,
but haven't needed it yet.
MAPP gas is cheap, and I can do just as good a job with it as others can using their torch of choice.

We have used ng/compressed air torches for many years on all of our benches, smaller tips on the woodwind benches. But, when we need a really hot flame, we disconnect the gas from a line and connect propane/compressed air, as it produces a much hotter flame.

There are some new and improved Portable Butane Torches and Burners available form the website: www.porta-lab.com . Worth taking at look at!!!

We have a natural gas/oxygen torch and the type "B" tank acetylene torch. I prefer the Smith torch to the prest-o-lite handle and tips. The pret-o-lite seems to need "O" ring replacement quite often and the Smith rarely needs it. I prefer the Acetylene and our other Tech prefers the Natural gas/Oxygen tank version. I wish we also had an oxy/actylene. You may also want to try one set up with MAPP gas instead of Acetylene.

Jeff, I grew up using a natural gas mouth pipe for heating sax pad cups. Soft controlable flame. Slower than Ace but very controlable. Did alot of old lacquer sixes this way. But of course, when I was doing them they weren't that old! I think Ferree's still sells it
