If you work with rough lumber, a planer will be absolutely necessary, except for the most rustic of projects. Every piece of rough cut lumber ends up somewhat not straight, not flat and not consistent in thickness, either from variations during the sawing or from stresses which occur while the wood dries. The planer, combined with the jointer, is a one-two punch to remove these variations and produce straight, flat and consistently thick lumber. The reason the planer is ahead of the jointer on this list is that some lumber is straight enough and flat enough to plane without jointing if the job is a little less finicky, thereby skipping the jointer.
Timely article indeed. I’ve been playing with the shop layout tool on Grizzly’s website (http://www.grizzly.com/workshopplanner) which helps you see how tools fit in a specific shop size. However, your insight and experience really helps with ergonomic considerations. When I first built my shop, the first thing I did was installing a wall mounted work bench – as my fore fathers had all done – Big Mistake! Soon-to-be project: ripping it out and building a mobile work bench on wheels (like the one you have pictured).
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.
