[@elzeno2414]

Under air power or steam power, it's a pleasure to watch him at work. Thanks for posting!

[@ronicard]

Very cool. I've never seen it done by a machine shop before. Thank you

[@josephmagedanz4070]

Sure beats doing it by hand... Thanks for sharing. Joe

My, Mr Waller, you seem to have acquired a new accent. But I am not deceived, I'd know Dave Richards anywhere:)

That didn't look like David Richards steam powered shop.

Hello. This is the bread and butter part of the workshop where Dave has a complete set of automotive machines.

Looks like "try and error"... Better use a professional valve seat tool e.g. the HUNGER valve seat cutter!

[@BritanniaMotorcycles]

Dave has been rebuilding heads for forty years including race engines and his own dragsters. It is the man and not the tool and his valve seats are finalised using a seat dial gauge which reads to 0.0001".

May be - don`t take me wrong, but grinding stones for valve seat repair are out of fashion (for fourty years)...
