I am about to embark on making solid wood doors.
I am thinking of using the 2 following methods. Doors will be +-50mm thick (2 inch)2040 X 820 and some 1200 wide.
1. 5 off 10mm thick X about 150mm wide purpose cut, planed to exact thickness, grooved joint ( finger joint) and then glued up.
The 2 outer layers will be strait up and down the door to look conventional, and the 3 inner layers will be glued up at 15 degrees to each other ie: 1 left 1 right and the last one left.( cross veneered all in the same timber).
All of these glue ups then vacuum bagged to glue up the final veneerd door( a lot of work but I am advised worth while and very stable?).
Method 2
2. Making up a rail and stile assembly using say 150mm wide X 50 thick rails and stiles mortised together, and also cut a groove to suit 16mm marine plywood around the inside of the frame (prior to glueup) and fitting the marine ply insert and then veneering on each side 17mm X 150 wide solid wood planks onto the marine ply, these planks will have finger glue joints for added strength, the whole lot vacuum glued together to form a seemingly solid wood door..
Please comment on the above as I don't want to get it wrong from the beginning.
By the way these doors will be for exterior house/office use mostly under cover but still getting cold on the exterior warm inside ( winter days) and generally not rain wet.
Also would anyone like to suggest adhesives types.
Many thanks
