I have a reasonable array of tools but here's what I found best, in order of usefulness.  With the exception of the table saw, all of my tools are DIY quality, they work but have their limits so they must be used with care. I built two benches, each 2.5 M long, and placed them either side of the table saw.  Without them, I would not have been able to handle the long strips by myself.  With them cutting was just a matter of sliding from one bench, across the saw, then onto the other.

I also built jigs for scarfing, planing, joining scarfed strips and these proved very useful.

Stanley Block Plane Most useful. Used nearly every day.
Spokeshave For those awkward corners
Jig saw ( Black and Decker ) For cutting the forms, hatch apertures etc. 
Sander ( Bosch PSS 230 ) Not ROS. Very useful, but changing paper a bit fiddly.
Clamps You can never be too rich, too thin, or have enough of these. 
Packing Tape Useful for lots of things when glueing. I used 10 rolls !
Inca table saw My old work-horse. Never lets me down. I find it extremely useful as I can't cut a straight line to save my life.
Chisels I have a range of these. Keep them sharp and they can do almost any job.
Stapler I used 1500 staples.
Hand saws, files, rasps For all those other jobs
