Is there a rule of thumb regarding where the pins ought to go in the stile in a pinned tenon? I have made some very large arched-top doors using 5″ rails and stiles. It is 2″ red oak with over a dozen mortises to pin. The middle rail is a through tenon and the kick rail is a double tenon all others are getting one pin but I was wondering, for both aesthetic and practical joinery reasons, if there is any wisdom on this.
Thank you for your time.
