Crib slat joints to rail
I'm planning a crib design for my grand-daughter. I'm considering the various joints to use to secure the slats to the top and bottom rails.
Among the traditional options are mortise and tenon or a dado groove running the length of the rail with spacers in between each slat.
The slats will be 3/8" thick and 2" wide. Is there a good reason not to simply butt them to the top and bottom rails and secure them with two sheet metal screws through the rails into each end of the slat (4 screws per slat)?
With eleven slats or so, that's a lot of hardware holding the assembly together although I realize it's not exactly a fine woodworking technique.
Thanks in advance,
