Just as a FYI I finished all of the 200 parts on Tuesday. I had to machine all four sides and take 0.014" off of them. If I only machined two sides the material would bow about 0.020". But by taking 0.014" off of all four it stayed within 0.005" of flat. Good enough for a 7" long part.
I wish I could use 1/2" material but this bar has to go between two other parts that have 12mm grooves machined in them.
Thanks again,
