I can't speak to Maine, but every pre-revival frame I have examined where I could see a joint that was taken apart was undoubtably draw-bored.
In England several years ago, I was at a Framing Rendezvous in Oxfordshire, UK and was shown an old timber with a tenon on it by Steve Turner. The evidence for how they marked the draw could be seen as plain as day -- this timber was from the time before drill bits with lead screws, so you couldn't just run the bit down the hole. Instead, when the joint was assembled, they had taken an awl and poked around the peg hole, leaving the outline of the hole marked with little pin pricks on the tenon. Then they had offset the drill bit and drilled the tenon. Steve said they had wondered for years how they marked the draw without an auger bit, until someone had looked closer and seen the tiny crescent shaped pricked outline on a tenon.
I wonder how much we all miss when we look at a frame or a timber or a joint?
