Am building an end table, my first, and would like some input regarding mortise and tenon dimensions. The legs are 1 1/2 square and the aprons are 4 in x 3/4 in. My question is how to size the M&T. Thinking tenon width to be 1/4 inch and tenon length to be 1 inch. Width to be 2 inches. Is that reasonable or not? Appreciate any feedback. Thanx.
