I've been working on building some literature storage shelves for my office. they are 33" tall and 30" wide and stack on top of each other. We built 20 of them out of 3/4 mdf. I needed a way to cut down the mdf before cutting to size on the ole BT so I built the table shown below.
It starts out with a pair of saw horses bought at the Borg. These work well for this because they have notches on the top that accept a 2x? and each leg is adjustable so if you're working on a slight incline as we were for this project you can level the table out.


The two runners were 2x6 and the cross pieces are 2x4. I made the table a bit longer than 8' to accomodate the MDF.

To saw the MDF in half lengthwise I attached a 2x4x8 to the side slightly raised to act as a stop to push the MDF against. I have a long aluminum straight edge (not shown) which was clamped to a 2x4 screwd to each end, this time raise so the top of the 2x4 was about 7/8" above the table top. With the straight edge clamped in place all we had to do was hoist a full sheet onto the side, slide it under the straight edge and against the stop, then use the circular saw to cut along the straight edge. After slicing 10 pieces in half I removed the long straight edge and on to the next step.

Now we needed to cut the halfs into three pieces that could be handled easily on the table saw. I left the long edge in place and put a similar one on the opposite side. My 4' circular saw guide was clamped so that a half sheet of MDF could be slid underneath it and up against a stop to cut a piece almost 34" long. After cutting that piece was removed and the remainder slid up to the stop to ct another 34" piece leaving a 30" piece.


With the adjustable legs on the saw horses the rig could also be used as both a table extension and an infeed or outfeed table.
