Biggest piece of quartersawn maple you’ll ever see

[Boudoir Guitar]

I occasionally use a table saw to straighten an edge of a board. First pass I'll use a chalk line, then flip it and use that edge against the fence. Each time I flip it, I'm using a straighter edge against the fence, so it gives me a straighter cut.

Even though you can't use a chalk line on this, I'd use that same kind of thinking- plane the obvious high parts, then flip it and use that planed section to rest on, shimming where it's not making contact, and repeat.

Plus, it looks like you have plenty of thickness to work with, and it appears fairly flat to begin with.

I’ve got one side done / just the cupping across the face of the board, no significant bowing or twist. This MFer is heavy and flipping it solo is…not something I wanna do anymore than necessary.

Took four passes just because I wanted to be careful to take as little material as possible. Lost maaaaaybe 3/8” total on this side? Other side might sneak up above 1/4” or so. Still not quite sure what I want to target for final thickness, but nothing thicker than 2 1/8” which this should allow for.

Since "annoying YouTube clickbait" is being discussed elsewhere, I will assume anyone reading this thread will love this channel -- no talking. Just making:

I did a first stab at "flat" on both sides of the big slab -- both are "flat enough" but not perfect, but I've still got a solid 3/8" of thickness to work with so can go back and do some iterating finishing passes now that each side is more flat than before as suggested @TSJMajesty

Another thing I do on occasion for really wonky crowned or rough-edged uneven boards that are manageable, is grab another straight board as possible (maybe a plywood rip) close to length and secure with just enough 18 ga nails to the weird board. Then run that straight board up against the fence which will give you a good straight cut on the odd board to get you started.
