Marc, would not assumptions for a Festool shop differ considerably? Far fewer big machines, and more carrying lightweight precision machines to the wood, for example. I only have a few Festool machines so far (took quite a while to get past the sticker shock), but I am beginning to see how it could change the way we work. My 400 sq ft shop is getting awfully crowded with floor-standing machines and implementing your guidelines, sound as they are, is difficult.
Well you can only do so much with your given space. These guidelines are just general best-practices, but that certainly doesn’t mean everyone will be able to execute them to the letter. Even I make concessions for my personal situation. And yes, there would be differences in a Festool shop. I imagine everything would simply revolve around an MFT. :)
Even if you buy your lumber already planed, you will still encounter many circumstances that require the use of a planer. For example, you might want to build a simple and delicate jewelry box out of small scrap pieces lying around the shop, and you will end up making a small and clunky jewelry box because all of your lumber is 3/4″ thick, and that’s how it is going to stay. That is just the first example. Think about all of the other times that you will pick up a piece of lumber in the shop and it will be the wrong thickness, either just slightly wrong or in an entirely different size category. A planer is a real problem solver and can fix all of that.
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.
