How To Repair Cracks In Brass

Does anyone know how to fix cracks I have multiple cracks in a tank or is to unsafe and just use it as sparse
The latter I'm afraid.
You can see some of the cracks, but there are likely many more which have not yet fully penetrated.
Have a look at this old thread:

So don't waste my time with it then thanks for that. I'm just getting starting to get into kerosene stove I have 2 but 1 has cracks and the other has no legs.
@Ben85
Welcome.

Post some photos of your stoves, including the cracks.

@kerophile is probably correct if your stove has multiple stress-cracks, but it is still interesting to see them.

We'll be happy here to get you going with your stoves.

Cheers

I've never seen a Companion with multiple stress cracks like that. Does it leak with kero in it?

@Ben85
The words "big time" means find another tank... Companion tanks are pretty common.

Can you photograph any tank or part markings? I'm interested in knowing whether this is a very early or very late Companion as they are usually of the highest order of manufacture.

Best regards

G'day Ben,
BUGGER !

Tony, In the fourth picture the Companion shield (not Svea) can be seen above the pump tube.
The other one is a radius No 1.s:or

Welcome to CCS!
Before you attempt more soldering, I would advise MUCH more cleaning. Solder is like TIG welding, must be absolutely clean for any kind of positive results.
Think I'll give up on this one

Set it aside for awhile, you may decide to come back to it.
@Ben85
G'day Ben, to help answer Tony's question is the underside of the spirit cup marked Companion like this one?
But I suspect it won't be.

Hopefully you will have more success with the Radius.
I had a look but there was nothing
I could supply a tank for cost of post if you wish as I would not be willing to trust a weakened tank with pressure + heat + flamable fuel and a roaring flame. a failure would not be nice
A really good clean of the area to be soldered is necessary I would use 0000 steel wool and resin core solder
Or better still low temp silver with the right flux CIG or other similar, even with the solder you used it looks like you need a larger soldering iron or a small gas torch.
The silver solder is a lot stronger than resin core or plumbers solder.

Hi graham thanks for your generosity. There's 6 cracks maybe more I'm going to use it for parts the radius needs legs and the nrv is rounded. I could practice soldering on it to.
