You will need a few tools to finish your Hybrid 80% Liborator. We recommend a drill press, cross slide vice ( x,y vice), and a rotary tool (similar to a Dremel).
Using the supplied 5 smaller screws enclose the entire jig securely. This will ensure all the holes line up exactly where they need to go. The entire assembly should be secured inside a vise during machining.
The trigger pocket is by far the most critical portion of the machining process. We recommend the use of a drill press and a cross slide vice ( x,y vice). The most important thing during this is patience. This is not an easy thing to do by hand that is why we suggest the cross slide vice ( x,y vice). Remove material with the end mill in .25” steps in the shape of the fire control pocket. Remove material till you reach a finale depth of 1.22" Use of a rotary tool and sandpaper can help smoothing the material to a finish.
The trigger hole guide is simply to make the hole for the trigger to go through. Using the drill bit carefully make the hole all the way through the bottom. Afterwards, clean the edge using some sandpaper or a Dremel tool.
When drilling the holes for the trigger pins and safety selector DO NOT drill all the way to the other side. Flip the assembly over and drill from the correct side. The jig is designed to center the part on the bit so before securing the jig to the work surface center the bit on the part with it not moving to ensure it is aligned. Do not reuse the jig after assembly. They are designed for a single use only.
