It's my first real plane, a Stanley #4 of current manufacture, made in England. I've read lotsa stuff about tuning planes, and have spent a lot of time futzing around with this thing. I've got it tuned to the best of my ability, and I think it has turned out pretty well.
So now I've got the thing ready to go, and fooled around to get a feel for how to set the iron just so. I'm making whispy thin shavings, and the plane is just singing along.
So far, so good, but here's where I need help. The surface I've planed is dead flat, but it isn't parallel to the opposing face. Not by a long damn shot. I've been practicing all day, and I've shaved this board down to about nothing without ever getting it flat. I keep ending up with something that looks like this:
==========__________________ ======================================== ======================================== ======================================== ========================================
Of course it's not actually stair steppy. Perfectly flat, just angled wrong. Not only across the width of the board, but along its length too, so I wind up with something that might want to be a structural member in a doll house built by M.C. Escher.
If I try to take off the high side, I eventually end up with a crown in the middle, or wind up making the high side the low side. I've been chasing my tail like that for hours.
The board started with a reasonably flat surface, and I was originally just trying to remove some tooth marks. I don't think the plane is riding on anything to cause this.
I have a really cheap face vise (one of those $12 Columbian deals from Lowe's) with the board clamped in that, if it matters.
Anyway, I could use some tips here. There's a lot more to this than just making whispies, obviously.
