[Steam-engine] Gauge glass valves

[Richard Selway]

Hi folks,

Would just like to get everybody's opinion on bedding in a couple of valves 
that leak constantly on a gauge glass set up on a friends traction engine.

I've applied engineer's blue and there are a number of scores on the tapered 
plug and seat. I don't think they justify setting up the valve bodies and 
plugs on a lathe and re-machining the seats (which is a job I don't really 
fancy if i'm honest!) Somebody mentioned using grinding past, but would this 
not bed itself into the valve surfaces permanently and constanly be 
re-cutting?


Any advice would be gratefully received.

All the best,

Rich
