It has made me really think about doing things in an order which optimizes the switching around of machinery. One thing I did do which has really helped and that I would add to your list is SOUND PROOFING! Didn’t mean to yell there.. lol. Sound proofing has has allowed me to keep the workshop operations from bothering the rest of the family when I am in my man-room.
I’m 91 years old, but I still enjoy spending time in the wood shop. I like to make wooden toys and give them to my great-grandkids and charity groups. One trick I’ve learned over the years is to use emery boards—the kind for filing fingernails— to sand small parts. Emery boards come in different sizes, and some are more abrasive than others, so I keep an assortment on hand. — Joe Aboussleman
Position #3 is where you will likely spend most of your time in the shop. The diagonally placed workbench is the heart of this plan. The wall-mounted workspace that surrounds the bench forms an ideal “work triangle” within which each of your most commonly needed tools is only one or two steps away. The band saw can be placed outside of the work triangle because it is used slightly less frequently and often needs a little more space around it for your lumber to move.
Unless you’re a big fan of frequent shop remodeling, planning the layout of your workshop early in its development will save you a lot of time and trouble and also can keep you from spending years in an uncomfortable, poorly organized space. And if you already work in a shop that’s as organized as a trailer park after a tornado, careful planning and a little remodeling is likely to help you make a quantum leap.
