Well Scott, I once used a stop watch to track my time on a particular build - never again. There a '49 Ford on my bench that's in it's 3rd week of work ('57 Chevy headlights, '57 T-Bird taillights, radius & flared rear wheel wells, and more). It's requiring extensive body work and that takes me time. I also have a '40 Ford pickup with a VW bus where the box was. That one has been on the bench for several months.
I posted 3 builds in the last couple of days but they were completed, pics taken, and sat around a few days before posting them.
