I guess I would have to buck the trend as I have not changed my shop layout very much. Now this might be because it is small in size (12 x 24), but I tend to think it is because it is laid out pretty well.
The thing of it is, I had some very crappy shops over the years, from a 1950's built logging camp, to a a spare bedroom in the house. So when I got money enough to build a decent shop, I had been planning it out for years.
In the three years since I have had my shop, the only change I have made is moving the band saw closer to the front of the shop. That was because my bandsaw is my go-to machine and it was just too many steps away.
I have no intention of traveling from birth to the grave in a manicured and well preserved body; but rather I will skid in sideways, totally beat up, completely worn out, utterly exhausted and jump off my tractor and loudly yell, "Wow, this is what it took to feed a nation!"
