I did a 3 piece a while back with that I though was minimal tools and I had: Japanese pull saw, rasp, files, Benchtop belt sander, homemade lam grinder, drill, and about 100 spring clamps .... plus the form obviously. Also had to buy the hardware to put it together, which isn't terribly expensive, but doesn't help keep the cost down either.
My last plea is this: for four years I drove and hunted using a 2 door Audi TT coupe. In all that time, even with the tiny interior, I never bothered taking apart either of my three piece bows for transport .... it's just not that convenient, and I found that it was a novelty I never made use of.
Anyway, keep us posted.
