I posted yesterday about where to get new knives for the Rockwell
jointer 37-315 that I am restoreing. Thanks to all who pushed me in
the right direction.
As experinced woodworkers might have geussed that before the knives
can be replaced you need to get them off the cutter head. That is
easier said than done. I need help un-freezing the nuts that hold the
knives in place. As soon as I came to a stuck nut I stopped in fear
that I would strip them.
Thanks again to the people that have been helping me out through out

The thing that helped me the most was to take a large hammer to the
side of the thickest 8mm wrench I could find that would still fit in
the slot in the planer head. Whacking the side on an anvil closed up
the wrench until it was a very tight fit on the nut. That let me but
more torque on the nut without fear of rounding it.
If you try to apply heat to the bolt head it will work to expand the
bolt and cause it to freeze even more. You want to heat up the area
around the bolt but not the bolt itself. Sometimes that is easier said
than done. I would go for the lubricants first. But be aware that if
you do use them you should not put a flame anywhere near them later on.
I would use a six-point socket on the bolt rather than a wrench. You
can add a breaker bar and apply tremendous torque if you need to. Be
sure you rap the bolthead with a hammer several times after applying
