Planning out your workshop usually means a lot of moving stuff around and trial/error, here’s another approach, make a miniature model… Pfred1 writes – “I used the architectural scale 1/4 inch to the foot as my scale. Heck, after a while it was sort of fun to make scale models of all of my junk. In the process I even remade a few of the models nicer than I had initially. The models are made out of scrap cardboard, and toothpicks, hotglued together, then painted with craft paint. Nothing too fancy there. But everything is to scale.”Link.
