I made one very similar to Roger's, but with no cover.
One problem that I've found is that different so-called 10" blades are different actual sizes (I suspect, for example, that the Freud blades are actually 25 cm, as they're a little smaller). The smaller ones are right on the edge of falling out of their slots (I foolishly made the thing sized for 10" without checking actual blade sizes first :BangHead: ).
Due to that minor size difference, plus having an assortment of 7" blades, the "chest of drawers" approach in the other related post is looking better to me.
