Tonight when I did my small orders (5 and less), I decided to refine the box to to make the gluing faster.
I decided to try and have the parts interlock so that I wouldn’t need as many clothes pins to clamp them. Clothespins are pretty fast (what a cool invention) but it’s still a significant amount of time (everything counts).
I was able to get an interlocking thing going that seemed to drop quite a bit of time off the assembly time. Of course it took a lot longer to do the small order boxes (the smallest size I make). But at the end I shaved time off the creation of future boxes.
Now I have box up the larger orders of model airplanes for tonight. I only make boxes for orders under 30 or so since there are lots of off the shelf boxes available for that.
