Power planing glued up panners

Map,

I must admitt that I have never attempted this… I do not think this is a good idea, and if you try it do not stand behind the machine, especially if it does not have anti-kickback dogs.

I think your second notion is better and what I would do in your situation, plane to just a hair thicker than your final thickness (0.5 mm) then, with clean, straight, hardwood packers (at least 4 maybe six, for across )top middle and bottom) and well dosed out glue portion and you have it made. and little sanding and glue scraping, but thats not a problem normally.
