> So if any contented yuppie bastahd infill owners would
like to run a feeler gage through the mouth of his or her pride and joy,
and speak to the agony, or ecstasy, of plane with that configuration,
I'd be appreciative.

   I used a custom Hock blade and lapped it to get a mouth opening of .003.
I had to get a custom blade because Ron didn't offer his infill replacements
back then.

 Why a .003 mouth, you ask ? Cause it finally slipped through the mouth
opening and I was tired of lapping.  It can plane most any wood I've tried,
with or against the grain, with no tearout.

  Stick a 3/16" chunk of metal or something in the plane and see if it
clears the mouth. Then order a plane blade of appropriate thickness.

 Go with the tighest mouth you can accomplish, the whole point of these
infills is final smoothing, and that is best done with a tight mouth. You
can do your preliminary smoothing with a regular smoother and save the
infill for the last few passes.
