Hello, here is another one.

My BAT (with a roarer burner made of copper) develops one problem after another. I have discovered an erosion at the location where the jet is soldered on: it is shooting an orange flame through it. This happened right after I have brought the burner to the point that it produces a symetric flame of blue cross.

It appears the burner needs a precision welding job. If I choose to go home-remedy route, what are the equipment that I need to use? Or, should I look for a pro to do it for me?

I tried to melt copper wire into it with a blow torch, but no good. I need something hotter.

Has anyone encountered a similar problem and fixed it? Could he then gracously share the knowledge?

I had a problem with a BAT burner leaking from the brazed joint where the U-tubes join the cup on a silent burner - instant underburning. I fixed it by silver brazing - a Bernzomatic MAPP brazing torch would do the trick using borax/sodium fluoride flux - don't breathe the fumes...

Thanks for the info. I went out and got the MAPP torch and other accessories. Broken heart, broken bank...

Before I light up the torch, however, something told me to light the burner one more time...

So I did... No leak... Hmm!!

It may well be that the JB Weld that I slapped on a few days prior to posting to this site actually was working... At the time, I let it cure only for one day. When I lit up the burner, it leaked: JB Weld burned and melted. So I let the stove alone for a few days in disgust, while I was seeking information to fix that thing.

I guess that extra days of "curing" time did the job. I will just let it be, and if it springs a leak, then I will give it a tender, loving brazing.

I think you might end up brazing it because the JB weld is only good to 600F. I had thought of repairing a lantern vent with it.I read a package of it today. Dan

What good remarks can I say here. Let me think for 1/2 hr.
Times up.
They are cheep. They are lighter than the older stoves of the same size, (because the metal is thiner).
You can get them new, and parts is available if you know where to look.
That is all I can think of.
Now bad comments Not enough room.

Yes, Albert, BAT seems like a lightweight version of the good thing. But I can't seem to bring myself to disown it.

I managed to braze a dab of copper and sealed the leak. It looks like it will stay that way for a long time. Interstingly, though, all the "warm" attention from the MAPP flame seemed to have loosened the jet a little. Now I can see a tiny flame springing up when it is pumped to the max--this turns the blue flame into an orange color. Must be throwing the fuel/oxigen balance off a little.

Is there a tool that is dedicated for this sort of purpose? Or, is there a way to fashion a home-made tool to tighten it a little (perhaps a length of tubing with a slot cut out)? Or, is the jet tightenable at all?

Yes I know what you say about not throwing it away. I have about 6 of the buggers here. I get them when bidding on a lot number with mix stoves and lights. A lot of these stoves have cracks in the tank. I believe this is caused when the tank is being pressed.
If that jet gets too loose the stove will only work for about 4 minets then black sooty smoke bad. What hapens here is there is too much fuel getting out though the leak and jet together. This causes the burner not heat the fuel enough and allows fuel out insted of vapours.
This jet will have to be tightened. For this you will have to have a special tool with a double swivel on it. This tool will fit all the same type of stoves.
Making them well yes this can be done if you can use a lath and a milling machine with the know how and time. But for the normal person no it can't be done. I don't know of a way to tighten it with out the tool. Can you borrow one for a day.
I know when a person bought a Handi stove years ago this tool was suplyed with it, it was probably suplyed with other brands as well.
I am constantly looking for them although I have 2 here for sale. I would say Base camp and other places would have them also.
Good luck with it

Hi,
I made my 1st jet tool from a stub of an Allen screw with a slot cut in it and a cut-down Allen key to fit under the burner head. Now I have some 'proper' tools!If you are UK-based I'd be happy to lend you either Please contact me off-Forum if you're interested. Or you might come along to the next UK meet where there'll be an aweful lot of fettling going on!

Hi, Colin,

I live neat west coast of USA, so I may have to save up for the air fare to take your offer. UK is a country I intend to visit at least once in my life time, however. It will be great to attend one of those gatherings, while I am visiting.

Using an Allen screw is a great idea! I think I can definitely try making one myself!

Thanks for the great info.

David.

I went to a local harware store and bought a couple of Allen screws, and scored the center with a cutoff wheel and filed it down to the width, and cut off an appropriate length of the Allen wrench.

The result: it did the job, and the jet is not leaking.

Thanks.
