You can build sophisticated jigs like this to solve your milling problem: http://www.finewoodworking.com/workshop/video/a-planer-sled-for-milling-lumber.aspx (Check this out by another LJ: http://lumberjocks.com/Koonan/blog/4733)
Handplaning is another option but to mill lots of lumber, I go with my thickness planer. Here’s my simpler “jig” to flatten some of my twisted, bowed and warped stock:
1) Cut a flat sheet (plywood, MDF, etc.) to size that is longer and wider than the rough lumber, but not wider than the capacity of your thickness planner
2) Place the rough lumber on the jig (sheet) and use glue (from a glue gun) and shims (http://www.leevalley.com/en/wood/page.aspx?p=66917&cat=1,43456), if needed, to “stabilize” the lumber so it doesn’t rock (Tack a couple brass pins behind the end, if desired)
3) Plane one side flat and then plane the other side (Take even material from each side and also cut your lumber to rough width before milling it).
Even if you have a jointer longer and wider than your twist lumber, you may not know or have the proper technique of removing the twist. It is different from milling a cupped board. This simple method is almost fool-proof.
