Nix the heat idea, It could weaken the shaft (lose temper) causeing more
serious problems in the future, like a broke shaft with a spinning blade on
it.

Ryobi from Home Depot ... I realize it's a reverse thread.
Ryobi supples two wrenches and there seems to plenty
of torque. Still under return for 45 more days but I hate to
return an item this expensive because someone overightened
the nut at the factory. If I get the nut off will I have damaged
anything? ... I mean if the damage isn't obvious. Is there any
damage done from overtightening in the first place?
