Thanks to all for the kind words. They are much appreciated.
This is South American wood that looks to me like Sapele. It is to us like poplar is to you guys- readily available and relatively cheap compared to shopping in from the US. It has very tricky grain and a lot of tension, but after it settles down it’s solid stuff.
It is a mix of physical therapy lifting and pushing heavy wood, and mental therapy enjoying seeing a beam opened up and seeing the grain for the first time. There is also aromatherapy- smelling sweet mahogany. :-)
I accounted through prayer and holding my mouth just right. :-) Seriously, though, with mahogany it is a challenge. A close look and you will see that the arch is insert into the shorter stile about 3/4” as opposed to gluing flush to the stile, ie it rests in a little ledge for strength. It was a pain to make that stopped cut, which I did on the table saw and finished on the bandsaw, but it was a critical element to help keep it all right. Not seen is there are tenons in all the joints in addition to the rail and stile profiles. The grain in the arch is also critical. Boards were chosen carefully for the arches. I mounted the top hinge to land right at the start of the arch, as high as possible, which was 50 5/16” up from bottom. By the way, architects are evil and design things in 16ths making me use a lot of fractional math. (Only kidding, architects, but I sure wish at least one thing on these doors was a whole number!)
