I have some 5/4 Maple to make drawer sides. Going for 7/16 thick after resawing. The stock is a little twisted. Cut to length plus 1/2" then rip to width plus 1/2". Ripping twisted stock is a little tricky. First I hand plane an edge kinda straight so it rips to a constant width. My push block is Balsa so the saw can't grab it and throw it back at me. It's big enough to keep my hands away from the blade and it allows me to control the stock. I hold the right edge tight to the table which means one corner on the left edge is raised. As long as it doesn't rock I get a good cut.

Since I have no jointer the next step is another hand tool exercise. Choose a side, set it on a flat spot and rock it to find the high (well low since it is turned over) spots and mark them. Plane them off and repeat. Once one side is flat it goes thru the lunchbox planer.
Then tune up an edge and resaw.
Oops, there is a pic attached of a log with twisted grain. I did not use it. Can't seem to delete it, enjoy.
