Dear all
I have a query about my oag gazebo project. New member so please forgive any i accurate terminology and general newbie errors!
My gazebo will have a pair of parrallel tie beams joined to the four posts by mortice and tenon joints (100mm deep mortices, 1.5 inch thick tenons). The beams and posts are 150mm. I plan to place two more beams on top of these beams and join using a mid lap joint similair to the images attached below.
Bearing in mind the mortice in the lower beam is 100mm and the beams are 150mm, how much depth can I cut into each beam to create the joint without the lower beam being weakened too much?
I hope this makes sense and forgive if my terminology is not quite accurate
Regards
Jon
