Hardwoods, botanically known as angiosperms, are deciduous and shed their leaves annually with temperature changes. Softwoods come from trees botanically known as gymnosperms, which are coniferous, cone-bearing, and stay green year round. Although a general pattern, softwoods are not necessarily always “softer” than hardwoods, and vice versa.
Once the workshop location is determined, it's time to begin planning how to lay it out. First, acknowledge the need to formulate a plan that's realistic in terms of the space allotted. The size of the structure or workspace will place some constraints on how much can be done. Taking into account size limitations, begin fashioning a plan that keeps efficiency in mind.
I have never worked with my bench up against the wall, because I like to work from all 4 sides of my bench. I do like my machines pushed up against the wall and a large open space in the middle of the shop to facilitate easier movement. I have a Minimax combination machine so by necessity my tablesaw and jointer/planer are bundled together but I would actually prefer they not be (like a Felder machine that breaks apart). I would never put my tablesaw central in my shop, always at one end with a clear entry and egress for the sliding table, space permitting. Putting a tablesaw in the middle always struck me as one thing I’d always have to walk around and/or fight the temptation to stack stuff on it.
