I'm in the process of finishing 6 chairs.
Rails, 8 tenons each chair x 6 = 48.
Back support slats 10 tenons each chair x 6 = 60
Back support rails 4 tenons each chair x 6 = 24
Arm rests 4 tenons each chair x 2 = 8.
Total of 140 tenons that need to fit perfectly.
With what I have a tenon jig on the table saw and my miter gauge was the fastest solution.
For the arm rests, due to contours, by hand with saw and chisel.
If I do this again, I sure could make use of a Festool Domino, even although it parts ways with traditional fixed tenon joinery.
