My main work table is 80"x96" with my mat cutter dropped on one end to be flush with the top of the table. It is 36.75" high and I HATE it! It was built by the previous owner by laying bakery racks on their sides and putting a particle board on top. I have it covered with cardboard, but I'm looking for a better solution. Although it has storage underneath for matboard, it is too high for me comfortably use (I'm 5' 1/2") and I have to stand on a stool to cut mats (to have a long enough reach). The v-nailer also sits flush with this table on one side. It isn't the best design since when I go to v-nail larger frames I have to flip up the top of the mat cutter so the frames sit flat to nail them.
I have a counter that holds froggy and a glass sheet to cool drymounted pieces.
I have another counter (42"x146") that I use for installing hangers/bumpons/stickers and wrapping on one end (about 67" of it), and serves as the calendar holder and paperwork "dump" on the other end.
I'm working on building new cabinets for glass, mat, and foamcore storage so I can build a new table. It irks me that the space in here isn't used as efficiently as it could be, and I'm working on fixing that. (The whole work room is about 20'x28')
I do also have an oval mat cutter on a table with wheels, and a table in a smaller back room with the saw, sander, and chopper
I love Wendy's idea about making the table pieces latch together. That may be in the new table plans!
(And just so its clear, NONE of this bad designing was my doing, I'm just working with what the last guy left. Eventually I'll get it all put together in a nice, clean, efficient way!)
