Ha. Good stuff.
My first frame was out of DF, reclaimed at that. Is there a more painful splinter than DF? I doubt it.
Sometimes I think that if the natives of New Guinea made their blow darts out of dry DF they wouldn't have needed to look for poison frogs.
Used a 1" Marples Blue-Chip for the whole thing. Holding on to the chisel top with 2 fingers in a deep mortice wilst trying to wack it. LOTS of smashed knuckles.
Bored every mortice with a electro-magnet based portable drill press. Had to weigh 80 lbs. Clamped it down for every hole.
Cut every brace mortice at a 45...all the way to the bottom.
