Edit: "I just got done making one of my by-pass tools this morning without taking a lock apart as reference. I used a scribe and a dial caliper to mark 11 lines on some wiper blade material from the edge. #1 @ 1.300 (providing a .290 throat cut). #2 @ 1.010, #3 @.930, #4 @.806, #5 @ .726, #6 @.602, #7 @.522, #8 @.398, #9 @ .318, #10 @ .194, and finally, #11 @ .114. Cuts were made leaving five bits with a height of .080 and with a bit separation of .124. The wiper blade material was filed down to a width of .046. The wiper blade was ground down between bits to .030 and then filed round to create a needle (necessary -if you want the tool to rotate ninety degrees). The tool works perfectly."
Dimensions are in the thread. I have not tried them, but being that they were written by the inventor of the bypass tool, you might give them a try.
