Lockology Disc Detainer Pick

thingiverse

Still waiting on tubing to arrive from China to finish these. These are made in both 2mm and 4mm versions, enabling top and bottom tensioning depending on the type of pick. Both handles have been checked for structural integrity and fit, the gauge model is super-glued into the tensioner and located by a slide-fit feature. This design focuses on the handle structure, while the rest of the pick will need to be made through filing, grinding, cutting rod, and round bar. Please see the material list and instructions in the included files for these parts, which are identical to those used in my other BB and LPL Disc Detainer Pick designs. Full AutoCAD drawings are provided for those who want to personalize or remix this design. In response to a previous question, I'm using a 180mm length for the 4mm inner tensioning tool, allowing full extension without clearing the gauge on retraction. I personally use 41L40 round bar for this part, purchasing it in annealed form as 6mm rod and then necking it down to 3.9mm. On the "Profile" pick, I drill the central hole before necking it down. This should help with your design process. I chose 41L40 because it's easy to machine and can be hardened and tempered afterwards. Two new files have been added: a 2mm (2.2) tensioner and its associated drawing.
