Hi Adam,

Love this, really neat piece of engineering. If only I'd have known about them 4-5wks ago!!

Agree with the 640 and not making it an overly tight fit into the web; iirc, Loctite do specify a minimum clearance don't they? i.e., to ensure that the 640 doesn't get wiped straight off when installing into a press fit scenario.

One Q: with the home mechanic in mind, and thinking at the most unlikely scenario (maybe), would it be sufficient to use blue 242 for the cap fixing (#4)? I'm thinking that it would be quite possible for somebody to over-do the heat to remove the cap and also soften the 640 holding the barrel into the case, ending up with a spinning and/or a partially removed barrel. It would also allow cleaning of the internal thread to be easier (assuming a diligent blowing through with cleaners and air).

But well done, like it [thumbsup]

Spencer.

ETA: Do the turbo motors use a different orifice squirter than the n/a motors, to maybe spray more cooling oil under a hotter piston? (thinking specifically the 964 Turbo, selfishly)
