Barry, what you have done sounds just fine to me.

Once I leave fresh boards for a while, I sticker and clamp them. They relax and stay flat ...

What I want to suggest for future re-sawing for drawer sides, depending in the thickness/width of the rough sawn board, is to saw it up in such a way that you can glue it together to create quarter sawn sides. This is the most stable grain direct for drawer sides. It takes extra work, of course, but for the piece of mind is worth it.

The process involves ripping a flat sawn board into strips, glueing these as a stack, and then re-sawing the result. It is not economical, but it is better construction.

Regards from Perth
