Yes it is running on air and that is the temp. rod .I am about ready to take it all apart and correct a few parts I don't like .Then I will put some kind of finnish on it also ,not sure what I am going to use yet . Just had to show it to someone .Thanks Dale
I would run it on steam before disassembly if it were mine. It looks as if you just need to finish the plumbing and cylinder cocks. And you don't really need the cocks to test steam it. You do want steam oil though (lubricator). Do you have the blowdown valve on the right side?
Yes I have most of the plumbing made just not installed .I also have the piping inside the boildler so that I can run super heater.I also have to re bore one of the cyl.witch, I have lined with ss.There is a gal in it. But everything else is pretty close to being done.Dale
