More great info! I appreciate that. Your process is generally what I am planning when I get done flattening the back of this blade. When I got it, it was way out of square and about as “unflat” as I’ve seen. I was also going to give my plane a little time to climatatize to my area. It came out of Washington state, spent a week in a Fedex container, and now it’s in West TN with me, so I didn’t know how much it would move.
As far as the lateral adjuster, I have files the pins on a metal plane or two when runing them up. I just am still pondering the thought of retrofitting another on this transitional. The rote appears closer and taller than the metal counterparts, and I’m not sure its going to fit. What would you do, Mike?
