Does Mapp-Gas get hot enough to braze?

I have a couple of cracks in a pedal-box top cover I'm working on, but lack the welding equipment to fix it. Do you know if Mapp-Gas gets hot-enough to braze them? Does any one have any experience with this process, and if so could you recommend some tips? I would post pictures, but my camera's just died on me; so unfortunately I cannot demonstrate the extent of the problem. One of them runs from the edge to the middle of the panel, and is pretty straightforward. Another (Smaller one), is a little more of a stumper; as it's smack-dab in the middle of the panel, and doesn't run to either edge. I would like to fix both of them, even though the top-cover doesn't serve any real structural function. Any insight on the subject would be much appreciated....

Mapp gas will heat too slowly, seriously warping the sheetmetal. A MIG or TIG weld is the way to go. Better yet, just replace the cover.

MAPP/OXY will do but, look on craigslist and find a Lincoln MiG, it's more flexible and won't hurt ($) you much more than MAPP/OXY. You could find a neighbor to share cost too.
Another op would be a used box.

Sam, I think that finding another cover is perhaps the best idea. MAPP gas does get hot enough for brazing and silver soldering, but as Jeff said, you will probably warp the cover because of the heat. If you can't find another cover in better condidtion then at least the part is small and light enough to ship so one of us on the board could weld it up for you and ship it back and that might be less expensive than what a welding shop would charge. Looks like if you're going to continue in this hobby of old cars then you'll soon be starting on the tool collection in terms of welding equipment. I started with an Ox/Acetylene rig years ago but these days with the inexpensive 110v MIG units I think that would be where I'd advise someone to start now. Each type of unit has it's advantages and uses, none is the absolute best for every job, that's why many of us have more than one type of welding system, but the MIG is the most versitile on the average MG project.

Thank you for your advice, and kind offer, Bill. I really appreciate it, and I might end up taking you guys up on that if I can't find a decent cover; though I most likely will be able to. MG's and British cars of all types are a great passion of mine, and one which I will carry with me for the rest of my life. The MiG setup you recommended will definitely be in my toolkit someday (Hopefully sooner than later.), though at this moment the main focus is simply in getting my car running reliably on the road; and fortunately for me that does not entail rust repair/major bodywork, so the welder can wait for the moment. This is (With luck) the only piece I will have to weld on my car in the near future, so I'm also thinkin' the new cover would be the better way to go..... Thank you yet again for your help! It will always be appreciated.....

Yours Truly,
