Coleman 249 Burner Damaged

This Coleman 249 (April 1957) came with hidden damage. One of the handles has worn through to the mixing chamber. I'm considering tapping and threading in a brass bolt and then brazing over the edge. I have a handle that supports the ventilator without using the carry holes. These lanterns are kerosene units.

Interesting the position of the damaged hole as it is worn on a downward angle but the hole is about 50% encroaching on the lower part whereas the other hole encroaches far less.

Any other solutions please (other than scrap it!!)?

First photo shows the angle and depth of the problem.



These photos show the bad hole on the left and the just OK one on the right.

That looks like a good solution to me.

Good luck, Iain.

Checked an undated and a 62 242B (that hole is a full 5mm too low), You could drill new holes and plug + braze old as needed..

 

Thanks Graham,
That’s a fair bit out of whack. Wonder how it went so wrong.
Will see how it goes.

Could have been a manufacturing defect on part of the casting.
Tapping, plugging with a brass bolt and re-drilling sounds fine.
Or, you can just directly braze-fill the hole, then re-drill to the correct depth and angle.
249s don't seem to be very common. I wouldn't scrap the burner frame for sure.

 

Thanks Myn

 

What a strange problem lain. I've got a large assortment of different sized bb's lying around, if one could be found that was a slight press fit it would seal your mixing chamber up fine, then you would still have the slanted bail hole to deal with look forward to your solution

 

Hopefully it can be repaired.

 

I’ll have a look through my grave yard I may have a frame and burner

 

Firstly thanks Darryl for the offer, mate. Much appreciated. @Darryl Durdin

I will just go with my repaired burner as I reckon it will work and be original.

Here is a photo of the repaired hole in the burner. I tapped a 1/4" BSW thread and got several turns in. I then took a brass 1/4" BSW bolt and in the end cut a small slot with a hacksaw. This would be for a screwdriver to later drive in the remains of the bolt. I then counted 5 threads and cut the head of the bolt off. Screwed it into the newly cut thread and it was now sitting about 1/16" below the surface of the side of the burner.

Then I brazed some silver solder in and left it proud above the surface. So I believe it's fixed. Will test it out soon and see.

Looking good so far ......

 

Now that’s a repair, very nice.

 

I too do like it when I have a go at things and they turn out good, good repair job
