I am in the proccess of building a 2 inch scale copper Clayton boiler, I have used high temp silver solder on the inner joint of the clinker access tube. However I am unclear if you need to use high temp.silver solder on inner tube plate joint to the inner firebox? Also do you need to use high temp.silver solder to join the water tubes to the plate that goes onto the inner fire box? (I had to fight to get the heat to put the fire hole ring in.) Do you need to use high temp. solder to fit the bushes to the outer barrel? The instructions I have are a little vague. I found building a "Mini" boiler easy ,compared to this large chuck of copper! Also found castings a little short of "meat" and modifications to the design are already in hand! Finally,do you bash the ash pan out of mild steel sheet or is it fabricated? Many thanks for any advice gived.
