So this is my first project I’ve posted. I saw this technique used on gates, window shutters and a very large set of shop doors. I found this in a small villiage in France where my mother had lived briefly after escaping from East Germany. I was struck with the simplicity and unique common sense of notching the crossbuck of a gate or shutter to keep the weight of the gate from sagging it. Thru My Aunt’s interperting I was shown this by the county foreman, who had built a very large set of shop doors. They were probably 9’+ by 6’. I also saw very tall shutters on some houses that had two diagonal crossbucks with a top, middle and bottom horizontal piece. The bottom of the crossbuck/diagonal was notched and adjacent to a hinge. The other thing I did to try and match
this to what I saw was chamfering the edges. I used a 45 degree router bit after I had it all put together. I later checked my photos and saw that some of the shutters, and gates had all the crossbuck edges chamfered,
even the notches. It gives it a unique look. I’m not trying to show off the finished project as much as the notch technique. It’s something I’ve never seen before. Hopefully, others will find it useful.
