[Steam-engine] gov/throttle gaskets

[quote] As I remember from Pawnee steam school the governor is never 
supposed to have a gasket between the top half and the valve body. [/quote]

Gosh....???? I always have used a Gasket between the top half and the valve 
body.... Have I been doing this wrong all these years....???? And my 
Governors have always worked Good too...???? Were they talking about the 
type where the top is held on by a set screw...????

Well.... the plug valve throttles are harder to fix than the Gate type. With 
the gate type you can clean up the seats and discs and build them up to 
space them a little wider. I believe about all you can do with the plug 
valve type is bore out the body a little larger and build up or make a new 
plug valve and machine to fit. If you don't have a Good Lathe and a Mill 
this can get to be expensive. I have known some owners to fix them but they 
were Machinests by trade... About the smartest decision I ever made when I 
put my little Case together was to replace the Worn out throttle with a Ball 
Valve....

I have seen on some engines they have fed the cylinder oil in after the 
throttle.... And you geussed it.... The throttle valves on these are always 
worn out....

When I take pieces the the foundry I always fill any bolt holes as there 
will be some shrinkage and I drill the holes in the new piece to fit. Any 
worn spots can be built up with Putty or bondo so you have something to 
machine.  Any rough spots / voids that will prevent the pattern to be 
withdrawn from the sand should be filled. There should be some Draft from 
the parting line so they can get it out of the sand.
