DOES CORRUGATION REDUCE FRICTION ON A HAND PLANE

Very interesting!
Scientific testing would indicate that the results should be reproducible.
Lacking the hardware, I cannot participate in the testing.

Wow. I'd say YES.

very nice.  The engineer that's left in me wonders about the other variables involved and how great their influence may be:  smoothness of sole, set up of tool, proper use of tool, and sharpness of blade to start.   I would agree that the corrugation should lessen the resistance, but I have to believe that these other variables can have a greater influence.  Hmm, fully designed experiment, proper gage R&R test, statistical analysis, DMAIC, 6 sigma control ......  Never mind, I'll just go with what Don has shown.

Not 6 sigma please!! 😀

I think a bit of studious application of Johnsons paste wax pretty much renders the argument moot. It may be my imagination, but in restoring planes, particularly the widely used Stanley No. 5s, the corrogated planes always seem to have a heavier build up of saps and paint/varnish residue on the soles. Also, they seem to be more prone to pitting, for whatever reason. Don...have you noticed the same thing?

I definitely haven't noticed a difference in pitting. A heavier build up of gunk just seems logical.

I'd also agree that the corrugated sole doesn't make enough of a difference in day to day operations. I believe it was a way to convince users that it was OK to switch to metallic at a time when it was being resisted. The other point I wanted to make is it wasn't Stanley who was pushing it.
