| If I have all the dimensions is there anyone here who can machine a cylinder type handcuff key? |

| I could make them pretty easily if you have an existing sample to take dimensions off of. Not familiar with how that lock mechanism works, so hard to say how important depths are. Do those pins just block the wrong key from entering and actuating the lock? Or do they actually function as tumbler pins? |

If you only need a couple then I would just use the opposite side and a right angle to mark out the edges of the new cut, and mark the depth needed. Then mount the dremel and hold the key to cut the two ends and get most of the material between out. Then use the side of a file to clean up the bottom and bring it to the line. But more than 3 like that would really suck. "D" might be an easier starting point. You'd only need to mark out the edges straight across the end of the key from the existing notch. I'd have no idea how to quote a price but I have some ideas. If I read this right: - You have a narrow long cut that is the 'index'. - You have 4 possible shallow tumbler cuts that are 90* apart and rotated 45* off the index. I'm wondering if I could 3D print a jig to index several at a time and make all the tumbler cuts in all 5 to 7 at once. Looks like a 1/8" endmill would do it if the end of the N key were held facing up. Is it a pressing need you have? I hesitate because I always find it's minimum wage work by the time you get done creating the jigs and setting up the program but it does look like it could be done but with a separate slot cut path at each key's index point. |
