We did use a lump of wood to hold the flywheel, because it most closely resembles what our
heads are made of....it worked well enough though, both on undoing those forking-tight flywheel
bolts and then doing them up again afterwards, although I seem to remember we didn't go the
whole hog of doing them up to the book-torque of a massive 105 Nm........you have to leave a
bit of room for creativity when wrenching, or the machines think they're better than the humans
and that would never do.
