Don't know what Ill power with them just playing with um . Made four of these .Gonna put 150 PSI tomorrow if they don't go to Mars I thank they will be ok with a safety release at 40 PSI
150 PSI is an awful lot for an un-stayed boiler. Additionally, over-pressure can actually weaken one by distorting the copper.
As I recall, initial boiler tests run at twice the proposed working pressure. Subsequent tests (annual) use 1.5 times the working pressure.
Just my 2¢ worth....

A really nice boiler build, thanks for sharing.

safety first most DEFINITELY

We all like "pretty work", but I'll take safe and solid over pretty most any day!
Looks to be a really nice large boiler Stewart .... what'ch planing on powering with it?

Copper boiler build. Built this one a while ago just got around to finishing it . I guess its safe checked it at 80 PSI for two hours it didn't go flying off to the moon. Its heavy 24 pounds
