Dimensioning pallet wood

[tatcho]

I'm looking for some advice on dimensioning pallet wood;

I'm making some shelves and cutting the pallets down to size and shape and over cladding (gluing then pinning) a piece of ply.

My question is; I want a uniform thickness to ensure as flat a surface as possible - but only want to reduce the thickness of the 'bottom' of the boards as I want to keep the weathered patina as a feature. What's the best and quickest solution?

I was thinking maybe a power planer?

I know all about selecting the right pallets and have a metal detector to ensure they are de-nailed etc, so no lectures!!

Thicknesser. The trick is to put them through concave side down so that they stay steady and don't rock. If necessary you might have to take some high points off the surface so it'll go through steadily. Scrub plane!!
