THIS... IS... STUNNING!!!! and STICKY TOO NOW!
Good day folks,
More pin modifications!
But let's do something different this time.
Pin in pin! The goal was a zero feedback lock picking experience. While the drivers may bind under tension the key pins would still feel springy.
The pin centers were drilled out using a 1/16 inch drill bit. Ideally this would mean a perfect 0.0625" diameter axial cut. Considering I was holding the drill bit with a pair of pliers while the dremel spun the pin the resulting hole probably fell into the 0.065-0.070" diameter range. Next, the serrations were formed using a diamond encrusted cut-off disc. By now the pin walls are very thin in certain spots. I had some penny nails with 0.050" inch shafts to use as the internal pins but I was worried that the brass outers might deform when tension was applied to the plug. Instead, I found the closest sized nails that were slightly larger than the hole diameter. The nail heads were filed down to fit into the bible chambers and the nail shaft was filed, sanded, and cut to fit inside the brass without binding. This was by far the most time consuming step.
The last picture does not show the final product. At that point the internal pins are still ~0.100" too long. They were shortened to accommodate the space taken up by the springs.
The above pins were lovingly placed into a Yale KIK challenge lock with paracentric keyway and sent to Farmerfreak. He has not been heard from since. RIP.
Thanks for stopping by!
