With the c-channel insert and bottom metal securely installed, an 11/32 bit was used in a drill press to drill though the stock and c-channel for the rear action screw, and through the bottom metal and stock for the front action screw. Using a drill press ensured both of these holes were drilled square to the receiver. Using standard 1/8” IPS lamp repair pipe for the pillars, both holes in the stock for the action screws were tapped. For the rear hole, the tap was run from the top down all the way through the wood, and for the front up through the front hole of the DIP bottom metal and through what little wood there is above it;
