Hello,

Just trying to imagine squaring up the peg holes in an entire frame because I have not done it on that scale all in one go and so my reaction, based on what I have done is that squaring up the holes is not really a big deal and even doing them by the hundreds doesn't seem like it would be so bad, and in oak would go quite well. It really comes down to a personal judgement.
On a practical level I have noticed holes being squared by taking the chisel from a mortice boring machine in the hand and using it with a hammer to square up round holes. There are some disturbing aspects of that idea that maybe could be worked out though. Also remember that Japanese pegs holes are not drawn, just straight, so draw boring with a square peg, while I've done it, is an incongruity in the strictest sense, (think about deflection of the peg for one thing), for what that's worth.

Greetings,

Don Wagstaff
