Nowhere have I seen anyone advise cutting tenons on a table saw by laying the stock flat and first cutting the shoulders and then nibbling away to cut the length of the tenons. Most 'experts' use a tenoning jig where the stock is perpendicular to the table.
A instructor in my son's school suggests using the former method, i.e. where the stock lays flat on the table. Why not use this method? He says it is a safer way to cut the tenons and gives just as exact result.
Thanks...
