[SEL] Making valves

[rdhaskell at juno.com]

Hi Ray.
Go looking for a used automotive valve at your local rebuilding shop.  I
have cut down lots of them for use in my engines.  Just off the top of my
head I think you will find a metric valve that is just a few thousandths
of an inch bigger than 5/16ths.  That way you can ream your guide to fit
the new valve for a close fit.
