I have scrapped building the separate workshop, but am going to reconfigure my garage workshop with the new Delta Unisaw as the heart of it (what else would a table saw be?).
I am going to remove my existing attached workbench that takes up 16 feet of wall (bends around a corner). It will be replaced by a 3 foot wide by 2 foot deep attached shelving unit that will stretch from the floor to the ceiling that will house everything under my existing workbench.
A new workbench will be built that will not be attached to the wall. I am looking at 24 or 30 inches deep and 6 to 8 feet long depending on space. It will based on workbench designs by Christopher Schwarz.
I will add a floor band saw and floor drill press to accompany the Unisaw. Everything will be on mobile bases. Due to space, I do not plan on having a floor jointer or planer, unless I find that they will fit (the Grizzly shop planner doesn't show them fitting). The plan is to use hand planes to prepare my stock, which means I will add them to my tool collection. The drill press will be used for mortising to save taking up space with a dedicated mortiser. I have removed a free standing metal shelving unit from the garage that took up space and have all the items from it under my current workbench.
It will not all happen overnight, but I hope to have it complete in the next year.
This will be a compromise from what I really wanted, but it results in me not building a smaller building that I want. I can transfer the workbench and tools to a new workshop building in a few years and then add a jointer and planer at that time. By then, I will have honed my skill with the hand planes, which will be a good compliment to power equipment.
Since the truck will be parked outside during this transformation, I may get used to it.
It is the only vehicle of ours that has an alarm system in it. It could lead to the car leaving the garage too, but my wife would never allow it.
I do thank everyone for their suggestions regarding workshop doors, size, heating, cooling, etc. They will be incorporated into a future detached workshop.
