When I had my picture framing business back in the early 80s, I borrowed a video camera to tape myself to determine where I was being inefficient.
I had several work stations for different processes and I learned I spent too much time going looking for hand tools that I shared with the various work stations. I built a cart with those tools and that boosted efficiency, but later I replaced the cart by buying a full set of tools for each work station. That was vastly more efficient. Also, I bought a dozen utility knives and at the start of each day I made sure all had a fresh blade.
Note: I went through 8 - 12 blades a day, typically replacing the blade (or breaking off the tip) for each new process. A poor cut would mean an extra hour of labor to correct it. Note: I cut on a glass surface (48” x 48”) for the cleanest cuts, and that helped dull blades quickly.
In any case, carts are nice. But evaluate. Am I better served with a cart, or with duplicate tools? If you are in a cart-only mindset you can end up with the less efficient solution.
And a wide angle selfie showing you at work can teach you a lot about your processes.
you find something … it’s definitely better than a concrete floor
