Flattening a Smoothing Plane Sole (with a Bridgeport) - is 0.001" noticeable?

[@danaparish1644]

Nice job! Great effort on showing the effect that a “dead flat” plane sole has on the efficiency of the plane. I don’t know of anyone else who’s done that work…

Thanks! I think it was a lot of work for a little gain but now at least I can repeat the process very quickly on other planes. It was a fun learning experience too.

Not trying to be negative or put down the effort and work you did at all with my incoming comment. I’m sure you did a fair amount of work figuring the issues out, as I get short fused with dialing in work. Me as a viewer, wonders about the blade used in the planes. Are they equally sharp? Are the cutting depths similar, angles, etc? It’s a gift and a curse to have a brain like mine 🥴 I enjoyed the video. Keep up the good work.

Perhaps that is a shortcoming of my presentation. The two vintage planes are very similar in every way and set up identical. Same iron, same sharpness, same chip breaker, same size. I intended to simply ‘make metal flat’ and ended up noticing that it actually makes a difference - albeit I only looked at very light finishing passes on a smoothing plane so mileage will certainly vary on different size planes and depth of cut where out-of-flat may not matter at all. I still have the plane that is out of flat so further comparisons could be done before I machine that one. - if you have follow up tests you are interested in ask now. I tend to over analyze and was worried this was getting out of the realm of practicality and becoming simply an endeavor in chasing zeros so once I had flat I called it a night.

@@samuelwiltzius "chasing zeros..." Love that phrase.

Interesting.🙂
