In order to make the table saw move in the directions I need it to, I need casters on all 4 corners. I am not a fan of this arrangement, it gives less control than having 2 wheels fixed. But I have to make compromises in order to get the shop arranged (or rearranged) the way I want it.
So, starting with getting the Bosch saw, and needing a place to put it, began a series of events that lead to the whole shop changing. This is just one of the events along that path.
