You can do it that way, but I would be inclined to fill it with water and check. Or do both. Better to find the leak now and fix, then have it come after it's all done.

I double welded the firbox chamber.Then I welded the tank inside and out on all sides except for the last panel i put on.I could only weld it from the outside.After all the seams and ports were welded.I then welded a cap over the water level pipe that exits the top of the tank,installed the ball valves for the water ports.I then presurrised the water cavity.MAX OF 10PSI ONLY!!!! I used around 8 psi mostly to check the leaks.I used glass cleaner in a spray bottle as it bubble up quicker than dish soap did..
I then sprayed all the seams inside the firbox,and then on the outside of the tank.
When you find a leak,mark the spot with something,Then dump the air out,then go back and do the weld repair.Then represurise the tank and re check for leaks.
This is a time consuming process but it is what has to be done.
You don't presurise the burn chamber.just check it on the inside when the whole thing is assembled. :thumbup:

So far I have the firebox complete except for the exhuast stack opening.  I pressurized the inside of the fire box and found that I had a couple leaks.  I made my repairs and rechecked.  After that I stood the firebox up right and filled with water.  I plan on looking for any water streaks in the morning.  I think I will do the water chamber as you describe just to be sure I will soap the inside of the firebox again.  I just don't want to have to deal with leaks!

I learned from a automotive teacher that windshield washer solvent and a couple drops of dish soap in a bottle work best for leak testing.  This is what I have always done and it seems to not run off the verticle welds as easy as plain washer solvent.

Thanks for the ideas.  I will post more pics soon.

Does anyone have any suggestions on what size gap between the top of the firebox and the water jacket?  Is 8" enough or should I allow for more?

i would say add as much room as your design can allow,or the amount of stock you have. you will have to allow alittle room for water expansion. overall your water capacity could be more or less with this decision.
