I always wonder why more people don't see lighting as the heart of the shop. Lighting is such an important contributor for successful projects.
When I'm in furniture mode it's my workbench, other times it's the lathe - wood turning is almost a totally different hobby.
My workbench is always covered in tools. The table saw has to be clear to use (safely) so I do much of my assembly on the table saw and out-feed table. (Oh, Eric, I'm winning the lottery tomorrow.)
I'm so squished in my shop, the most important place is anywhere I can fit...
That is all going to get fixed...when I hit the lottery...
My workbench serves as an outfeed for my table saw so they are both the heart of my shop.
My most important space is the space I do not have. I'm totally pressed for floor & wall space.
