How far do I go trying to repair this 249 fount? I've had it apart twice now to braze up holes and cracks. I am determined though. This old (1941 I think) 249scout was in very bad condition. rusty tank, completely blocked valve body and holy pick up tube. mason bees had built dirt houses in the air tubes.
Oh well, no harm in taking it back to work and have another go at brazing up the holes.
She won't be a pretty one when I'm done with it but ill be happy if it works 249scout fount.jpg

You may be better served finding a 242 fount and brazing the 249 fuel bung in. Looks like you have a lot of pinholes. They are usually the end of a fount as if you see one, there are usually 10 others lurking.
Jeremiah 29:11-13 KJV For I know the thoughts that I think toward you, saith the Lord , thoughts of peace, and not of evil, to give you an expected end. [12] Then shall ye call upon me, and ye shall go and pray unto me, and I will hearken unto you. [13] And ye shall seek me, and find me , when ye shall search for me with all your heart.

Admirable desire to revive this one, but it likely won't ever be safe.  Time to ditch it and move on.

Hopefully you cherish your eyebrows more than an ancient fount.

If you keep springing leaks it's time to go. I like fixing things, but there comes a point where it is not safe.

100% for replace the fount. the consensus is in. I will keep an eye out for more. they seem to be becoming quite scarce down here in nz. at least I have some good spares off it

I'd not be too worried yet since the fuel is kerosene. If it runs on CF or gasoline, that'd be otherwise, and you should really stop using it any further.
If you really couldn't find another fount, you might want to give it at least one last try. Completely remove all traces of rust within the fount first. Braze it up again but this time get additional reinforcement by having the fount coated internally with the POR-15 stuff. That should usually work if the fount has not thinned-out or rusted through too badly.

I wouldn't trust POR-15 on a compromised fount.   For that matter, I wouldn't trust any fount sealer on a compromised fount.

A few years ago, a member here contacted the different companies making tank sealers, inquiring about use of their product in a GPA.   Only Caswell's had confidence that their product would hold up.   I know some folks use POR-15 anyway, but when the manufacturer doesn't have confidence in their product, I certainly won't. 

I wouldn't be over-confident that a Coleman lantern is designed for kerosene since most run just fine on naphtha.  It's not the current owner of GPA's that have been modified to run that I am concerned with, but a future collector not knowing the history or the right fuel.  Heck, just look at Youtube videos or ebay ads.  Many people have no idea what fuel the lanterns should be using, and with a repaired fount, may not realize that they should probably have an extinguisher handy, and keep the lantern well away from kids, pets, house, and anything else that's not expendable.

I had one last go brazing it up yesterday and every time I put heat on the fount it finds more holes.
I think this is the end for this old 249. I reassembled it and it can now hang in the shed. i'll rob parts if I have too.

next, onto the 237 that is burning outside of the mantle

I might could fix you up with a good 242 fount, if it weren't that you're on the other side of the globe.

Is the filler bung different from a 242?

Well, James, good to know you've given up on it.  Just keep what's left intact, and you just never know when someone will have another fount.  There's other Kiwis that collect, as well as several from Oz, which would be reasonable shipping for your part of the world.

Well, looks like the fount's too far gone then. No sealers ( Caswells, POR-15 or anything else) would work on a fount that's structurally compromised. Its good that doubts and decisions had been cleared and made quickly. Would be good to mark it permanently in some ways that'll indicate to any future owners that repairs would be futile and dangerous.

I'm with Jim on this one. The POR 15 will eventually fail due to heat. Caswell's is an epoxy, epoxies crosslink and are thermoset, but they do not crosslink to the fount. Heat will soften epoxy.
You've got to imagine the worst case scenario-a hot fully pressurized lantern springing a sudden leak. Even kerosene when warm vaporizes a little. (see "flight 800 accident cause") If you were not right there, fire extinguisher in hand with the pin pulled, your house will burn down or someone will suffer very serious burns. Even a structurally sound lantern can be hazardous to operate if you don't know lanterns.

Thanks guys. lots of sound advise on here.
As far as permanently marking the fount, I might cut it open. I'm curious as to what the cross section looks like.

And, I won an auction last night for looks like a 249 although the seller wasn't sure what model it is. so wish me luck. hopefully its a runner or at least I can make a good one out of the two
