Alan, Could I be so presumptuous as to send you drawings of the saw nuts I have made? They are similar to the TFWW nuts in that they use a lock washer instead of a square shank to keep the bolt from turning, but the nut has an extended shank to provide much more thread engagement. The head of the bolt and the nut both require the handle to be counterbored to the same depth to end up flush. Anyways, if you are interested in taking a look at them, I can email the drawings if you send me your email address. If you like the design you are welcome to use it. I would not ask for anything if you decide to use the design. The only interest I have is in developing another source in case my machinist stops making them. Regards, Isaac
