Thanks Jack sorry if its bin a long time answering.
Got the last bit of soldering done this morning with John.
First up the foundation ring which is made from 1/4" square copper rod, just cut and file to fit, to stop the bits falling into the boiler when evering expands on heating we simply drilled 1/16 through the outside and into the ring and put some copper rivets into the holes, you don't hammer the rivets over just place them in so they act as pegs. Everything was given a short pickle and clean and a good fluxing and rods of solder placed over the joints with a double dose at the corners, and some flux on the solder, the fire box was filled with thermalite block to keep the heat on the foundation ring. I had a pic of this but deleted it by mistake

. Then with two butane torches we applied the heat it took quite a while for it to get up to temperature then as the solder melted we added more solder to fill the joints, when it looked OK let everything cool a bit then a quench in water and a pickle, this is the results.


Next we did the two bushes on the side of the boiler for the feed clacks, sorry no pics.
And the last soldering job for the boiler was the boiler tube plate, similar procedure as before this is the set up before soldering, rings of solder arround the flue tubes and arround the outside of the plate.

Two torches again with more solder added as melting temerature was reached.
We had to reheat and resolder two of the flue tubes as the solder had failed to flow into the joint.
This is the final result.

Well hopfully that all the soldering done, I've got to make some blanking plugs and fit the longitudinal stays before I do a pressure test, that will be in a couple of weeks as I'm still waiting for a calibrated pressure gauge.
Fingers crossed for the pressure test.
