I have a joinery job coming up which will necessitate around 40-50 mortise and tenon joints to be cut out. Now apart from the fact that this will be a mind-numbingly boring task, it will most likely take forever. Is there any good reason why I shouldn't make round mortise and tenon joints, turning the tenons (see, it's not quite off-topic!) and simply using a forstner bit for the mortises? The only reason why it wouldn't be quite as good as traditional m & t joints is that round tenons could potentially be more susceptible to rotation in the mortises but decent glue-up and tight-fitting tenons. together with a screw or dowel driven laterally through the tenon when it's in place should get rid of that. Apart from the fact that turning a round tenon on the end of square stock might be a little tricky I can't see any reason why it wouldn't be a good idea. Can anyone spot anything I might have missed? Any reason why it's not used more often - is it just that most woodworkers probably don't have access to a lathe? Thanks in advance.
Kind regards
