Plane sole flattening consideration : plane flex
Just posting something obivious, but took me a very long time to realize.
When flattening a plane sole, you just don’t go over belt belt sander or sandpaper all over : that would be ok if you were to equalize the surface, remove high spot all over, but still not flatten.
A point mentioned everywhere is the banana shape, which is to be cautious about, but I did not have that situation.
But with a convex shape (like a bridge) you would not simply rock the plane over sandpaper because that is going to flex the plane (say a joiner plane) and still take forever. You could do it unless very cautious to not flex the plane and have a very low grip.
I’m taking the layout fluid route and only remove material were it needs to be. Should get there faster, hopefully.
Like other said, if you count the time taken, it’s probably cheaper to buy new ones from Lee valley, but it’s personal now.
Hope that could help someone.
