I made up something quite similar for several of my tools. Made a
base which has a recess in it that fit's a 20" x 10" x 3/4" piece of
plywood ( basically an oversize router table ). Then I made up
several boards of that dimension and mounted my planer, table saw,
mitre saw and benchtop router table on each of them.
Whenever I need to use a tool, I just pick up the (planer, table
saw, mitre saw etc ) and place it in the base. Leaves me more room in
my small shop having one base for many tools. When not in use, the
tools have a shelf of their own and stack quite neatly in one corner
of the shop. The single base only takes up a fifth of the room that
all of them would need.
It didn't take me long at all to make up the base, nor the boards to
mount the tools to. Hope this helps.
