   I use my '77 freehand and follow up with a straightedge and a router.  I usually run the grain parallel to the diagonal (front edge) so I'm making 2 shorter cuts at 90 degrees.

   Why not just use a straight edge and a C saw or router with a 1/4" spiral bit.

   I know you would like to have a system where you don't need to fool around with a C saw or router.    :)

   The only thing I can see is building a large panel cutter with a adjustable miter fence. That you will need to use a infeed table to support it at the first of your cuts out feed to support it when you finish the cut.  The tapered leg jig you were using may work if you put a piece of hard board under it so ply sits on it and use two or three toggle clamps to hold ply down.

   Got a skil saw? - alias circular saw.  How about just a plain old handsaw?  You can always clean it up with a hand plane or rasp or similar.

   I'd cut it oversize and then clean up the triangular piece with a router and spiral bit. Can you tell that I hate working with full sized sheet goods?

   I use an 18 inch rip of 3/4  mdf and brad it to the underside of the shelf with the rip parallel to the long side then run the mdf against the fence .With the blade up 2" you  can cut through the shelf.

   I just did this little project for our exercise room.  I ended up cutting a smaller "triangle" out of plywood using my miter gauge (about 12" sides). I brad nailed a strip of plywood to the long side of the triangle.  Place one side of the right triangle against the fence with the other leg of the right triangle toward the back of the saw.  The plywood strip should be at a 45 deg. angle from the fence (front of the table) to the blade.  The blank for the corner shelf was placed behind the smaller triangle with a 90 deg angle under the plywood strip.  I was able to brad nail the plywood strip to the plywood blank for the finished triangle since I cut a rabbet where the nail holes were, but you could put self adhesive sandpaper on the bottom of the strip. Once this was set up, I just ran it thru w/ the smaller guide triangle against the fence.  It worked great.

   I hope this makes sense.   LMK if you need me to explain further or differently.

   It is realy easy just a scrap of 1/4" ply set the width of your saw cirf away from your lay-out line and a couple of brads, then run through with 1/4" guide against the fence. I do it all the time with any odd angle that needs to be cut. Fast safe and cheep.

   That is a good idea, I will have to remember that in the future.
