Wow! Amazing videos. Took me back to my graduate apprentice days in Hillington. Those long cylinder head holding down studs - on Friday afternoons near finishing time the six of us GA's used to meet up in the experimental shop and have a competition to see how many of the nuts (28 of them) you could torque down on a Merlin before your arms gave out. Loser bought the beer. Thanks for the lead to that site. Happy days indeed.
