Lordy this is a lot of puzzles. I'm sure I'm going to find a few that I'm going to want to build myself.

IF you know SketchUp (or just a very basic knowledge of it) you can resize each puzzle to your preferred dimension and UGH imperial using the "tape" tool.  And then draw in the appropriate measurements using the "dimension" tool.
Alternatively you might be able to convert the SU model into a CAD you are familiar with.

If push comes to shove, I could change the model to your prefered units and base measurements and create a PDF with dimensions.  Would need the puzzles name as there are far too many to do en masse.  

If your first cut is too short... Take the second cut from the longer end... LBD
