So I have this gratifying pile of tweaky GT6 engine bits (ported heads, HS6
carbs, lumpy cam, tube pushrods, ...) waiting for assembly in the spring
(windcill of -44 today and my garage isn't heated), and I get to thinking
that a faily simple lathe project for whiling away a few winter hours is to
make a set of spring keepers out of 7075 T6 aluminum. Dig out the mics and
calipers and draft up a set of plans from the originals and note a
peculiarity that I hope the wisdom of the list can shed some light on:
Why is the gt6 (and TR6) exhaust spring retainer (upper spring collar) made
in two parts? Am I missing some key bit of mechanical insight here or is
this just another example of British "never make it simple when there's a
more complicated way" of engineering?
cheers
Scott
