There was a very interesting article in the 7.25" news last time (I
think) about a "centralised" drain cock system which I am currently
building. There were no drawings, just a picture of the components and
the assembled item.
One thing I would like to do is test mine before I install it on the
locomotive, the question is, what sort of pressure do the drain cocks
have to cope with?
It obviously isn't boiler pressure as by the time that they are in use
the steam has done its work and it is being exhausted, but there must
still be some pressure there.
Does anybody have any idea how much (so I can set the air compressor
accordingly).
Cheers
