>I put the stock in the planer to get it square and true,
This is one of the most important operation, I knew. But this is impossible for a person who has no skill on hand-tool or power-planer.
I try to plane. But piece went worse.

(Thank you for showing a usage of "true")
>just a little bit over size then put them on the sander to put on the nice smooth touch with 600 grit paper
Thank you. I will try next time. (I wish I could.)
You are a kind to all members, also bank robbery, aren't you.
