I recently bought an old Boice Crane model 640 12" thickness planer
that was in serious need of an overhaul.

The overhaul is now nearly complete. I've reached the step where I'm
putting the blades back into the cutter head.

There is easy access to the head and cutters from the top of the unit
but access to the business side of the blades is extremely limited due
to a couple of cast iron blade guards.

I'm considering purchasing a planer gage but I haven't done it yet
because I can't figure out how to use it.

Should I buy a planer gage or how would you go about setting the
knives on this (or any) thickness planer?
