Also as a note these small boilers do not need a "pop" type safety, they tend to drop the boiler pressure to much. The larger ones it works ok for, as they have the steam volume for them. The weeping safety's in my mind are the best for the boiler on the mogul.

I know of some people that have attempted to make true scale safety's but they seem to run into the problem, that even with a short burst they release to much steam pressure. The problem seems to be that with the smaller boilers there in not enough horsepower (flash rate) to over come the pop safety valve. They seem to work much better on the larger, higher pressure boilers because with the higher pressure is higher a higher water temp. Thus making the boiler have a greater flash rate and can overcome the pop type safety. I would like to have a scale working valve as well but for now I will take what works the best for the application.
