I still had plenty of plywood scraps laying around so decided to make desks for the kids.
I bought plans from the nicest woodworker in the southern hemisphere and went to work. I still had enough material for the base and drawer unit and only had to order the tops. I went with 29 mm birch plywood with a laminate top layer.
For the undercut bevel, Neil uses his table saw but I was not very comfortable doing it that way (one of the many laws of woodworking I abide by, don't make the cut if you don't feel comfortable doing it). I used my new tracksaw and overhung the track a bit. Worked mighty fine. This method can only produce 45 degree cuts of course. You could prop something under the track to make a bigger angle, but again, I was not very comfortable doing that.
