I'm building an A&C sofa table. The ends will have 3 vertical 1/2" slats going into 3/4" stretchers. What would you recommend? Groove the stretchers and fill in spacers between the slats? Or mortise the stretchers and make small tenon on the slats? I've got either a 1/4" or 5/16" mortise set. The groove would be quicker and probably easier and really shouldn't be any different structurally should it? Since this is an A&C style I think everything would normally be mortise/tenon but with only 1/2" slats I thought the groove would be better. If I go with the groove/filler, should I glue in the slats? Thanks. Greg
