[Healeys] 100 engine bore for sleeves

[Larry Varley]

Thanks Greg, as with any machining operation some machinists are wary of 
anything that could cause a problem to them, and fitting liners does 
require skill and decent quality equipment. I'm using Andrew Blackwell 
race engines here in Melbourne for the machining and have no problem 
with his ability to do quality work. I'm happy to report back to the 
list on how it all goes.
Cheers
Larry
