Spill plane build 1, removing rust from the blade.

I am not much of a tool maker, but I have read about spill planes a couple of places and I think that they are interesting tools.
My boys would really appreciate a plane like that in the shop that they could play with and make shavings for a purpose.
One time I bought a large box of old wooden planes. It wasn't as nice as it looked on the pictures, and I didn't really need those planes. I can't even remember why I thought it was a sensible deal at that time. But that box at least contained a couple of extra old plane blades.

I found an old Ward blade that didn't have a chipbreaker, and I figured that it would make a fine blade for a future spill plane.
I also found a nice chunk of beech that Brian Eve gave to me during the Danish Chairbuilding Extravaganza this year. I brought both the blade and a piece of the beech with me this time with the intention of building a spill plane.

There are several different methods that will work for removing rust from e.g. a blade. Previously I have used sulfuric acid out here, because I wanted the job to be quick, but this time I am not in a hurry, so I have switched to the less aggressive household vinegar instead.
I once used that at home, and it works perfectly.

My setup is an old plastic container which will hold the blade, and then I simply poured vinegar in until it covered the blade.
Tomorrow the blade should be clean from rust if all goes as planned.
