I would like some input on a built in desk I'm building. The overall length
will be 8'6" and 23" deep. The desk will be built from MDF. (Yes I know
many would suggest using a quality plywood, but the MDF was free 5 sheets of
3/4 4x9.) The desk will be supported by basically two boxes 34" wide on
each end leaving roughly 36" in the middle for an work area. The desk top
will be supported all the way across the front and back edge. Is a single
layer of MDF going to work as a desk top or should I double it? The desk
top will have a small TV on one end and a computer in the middle.

Thanks for all the input on clamps. I was getting ready to order other
items from Rockler and will most likely add on some bar clamps.

Thanks
Robert R.

I'd be inclined to beef up the opening. maybe with a cleat across the
front and back. This is going to be very heavy and another layer of
MDF is going to make it a lot heavier.
