Re: stuffing cylinders with nylon rope to remove flywheel nut??
The best way I have found to hold the flywheel is to take a ratchet style strap or webbing strap, a nylon one about an inch wide will do the trick. Line it up on the edge of the flywheel and wrap it around two and half times so the end goes underneath the overlapping bit of strap. The flywheel should be rotated to wind on the strap until youve got two and half lengths wrapped around it. Know you will need to know whether your tightening or loosening obviously so you need to make sure the strap is wrapped around in the same direction your going to want it to stop rotating.
Take the end of the strap and wrap it several times around your boats mooring attachment to give an anchor point.
Take a big ratchet or socket wrench, hook her up to the flywheel nut and start loosening/tightening. Make sure the strap stays nice and straight and flush with the edge of the flywheel. I've easily got 105lbs doing this way and the flywheel never ever budges. I have loads of webbing straps lieing around as I use them attach the boat to the trailer, canoes to the car, surfboards to the car etc....!
Don't bother with a strap wrench, you wont get a good enough anchor point without another person to help. You can do this on your own.
Oh yeah, you need a flywheel with a fairly thick edge for this to be really effective I guess?
