Subject: [FlyRotary] E shaft nut
Y'know that massive nut that everyone has trouble getting off?
Any tips on how to get it on?
Tracy says 350 ft pounds. Phew. That's me jumping on the end of my torque
wrench.
How do I hold the shaft / counterweights / airplane still while I do this?
Any suggestions on where to get a 2 1/8 socket? That size seems to be
missing from my $9 socket set :)

John Slade (torquing up a storm)
John, most auto parts stores (real auto stores) will have a 2 1/8" socket,
sometimes they are a bit pricy thought - might try one that caters to
pickups and trucks. What I suggest is to get a plus 700 lb-ft air wrench
(borrow or rent - a smaller one may do, but most with a 1/2" socket are too
weak). It will spin the nut off in 3 beats and you dont' have to anchor the
motor, the motor's inertia is sufficient to counteract the torque with an
air wrench.
