Each strip is 1/2 the final dimension thick (obviously), but is the full dimension wide. Two things. First, after roughing down the strip, to get the sides square, and most of the pith planed off, I then proceed to scrape off the enamel. I then finish planing, from the pith side, to the rough dimensions. This is before heat treating. Second, I leave the strips quite a bit wider than is needed. In the tip, my strips may be 4 or 5 times too wide when I glue them up. I do work the sides down some, as I don't want a 0.038" thick strip that is 0.625" wide. On butt sections, I often don't plane the sides, at the roughing stage, beyond getting them square.
I don't have your dimensions, but based on the Lee Wulff Ultimate that OSD posted back in 2009, the rough planed tip strips should be something like 0.036, 0.043, 0.051, 0.058, 0.065, 0.073, 0.081, 0.089 (in thickness).
Once glued together, you then plane and scrape the section down to final dimensions, which should be something like 0.068, 0.082, 0.097, 0.111, 0.125, 0.143, 0.158, 0.173.
Your numbers are probably a bit different, as all I did was a quick .95 conversion on the hex dimensions, but that should give you the idea.
I plane the sides to final dimensions first, and then plane/scrape the top and bottom. Be sure to try to take just about equal amounts of material from both sides, and sight down the section frequently to make sure you aren't gouging.
