Did a few things tonight after work.
Blasted the tank and fittings and the aluminum gimbal mounts
You blasted the tank!?!? Oh dear, that will make it hard to polish up again.

Before refitting it you better check the soldered joints and give the tank a pressure test.
I am not sure what pressure they would normally run at but I would imagine 20 to 30 psi would be about it.
With kero stoves you should only fill the tank 1/2 to 2/3. More than that and you will be pumping the tank pressure up every 5 mins until it comes down to that level.
