I am building kitchen cabinets using 3/4" oak plywood. I'm using dado

attach faceframes to the box, but I've never tried using them to
attaches shelves to the side panels. Is this a feasable option? Can
biscuits hold the weight of heavy dishes on shelves? Most of the top
cabinets would probably get three biscuits on each end of the shelf.
If seems that there's not alot of wood to support the weight of the
shelf and the dishes.

Anybody try this before?

If you're going to dado the shelves into the gables, there would be no
real reason to use biscuits there....imho.

I was thinking of not dadoing the gables and just using biscuits on a
butt jount. Just concerned about the strength of the biscuits.

Rob

I don't think biscuits were ever intended for support. They can certain
reinforce something like a corner butt joint on a frame, but never
anything like shelves.

Hardwood splines, glued in place would have the strength you're looking
for. However, with plywood, keep in mind that if you put splines in the
center, only half the plies will be holding the weight. Dadoes would be
the simplest and strongest option, imo.
