Plane Sole Flattening
Not quite finished photo firstNot finished but as far as I'm going to take it.
Many hours later I still had quite a big void in the sole but no more patience for sharpening. The rest of the sole seemed reasonably flat I decided to start working from 120 grit to 600 and a quick finish on 2000 grit.
SuccessEven with a large concavity in the sole the difference was night and day. I did do a little bit of work on the back of the iron taking it from the factory finish to a cloudy mirror finish.
I could probably get it better with many more hours of work but I decided to take a break before I became sick of it and never wanted to see this plane again.
Getting BetterAfter a few hours it became obvious this plane had an issue and I was going to have a big job to get it totally flat.
Cue a few hours lost browsing Lie Nielsen and Clifton but eventually figuring I shouldn't be let loose with the proper equipment until I have had plenty of practice.
The IssueI was having success using my old plane for softer more forgiving timber but when it came to starting work on my Red Oak Tripod Lamp no amount of adjusting could get it working nicely. I treated myself to a float glass sharpening plate and starting work on the planes sole.
A short time later the lack of flatness became apparent.
