The block plane I got needed to be set up as I posted previously.
The blade doesn’t come off evenly. So I needed this corrected.
There are numerous descriptions about plane set up on the internet so this article won’t talk about every single step precisely. I just did filing the edge where the blade slides down to shape it parallel.
I think it’s better now as I got the sliced wood thickness less than 0.1mm.
And I worked on a small board and made it partially flat.
I will try some other wood to learn more about the block plane. I should get other types like a bench plane and a low angle plane then I get to know better.
Still I need to work a little more about this block plane: sharpening the blade.
