I need to attach legs to a skirt to mount a table top on - the top is 4 by 8 feet. I need to know if it would be stronger to dowel the skirt to the legs or would using large sized biscuits be better or equal in strength?? The legs turned legs, but the top is 5 inches square. I have a 5th leg to go in the middle of the table for strength. The skirt will be made from wood that is 100 years old and measures true 1 1/2" by 5 1/2" and is very hard.
