Good Info....And here I thought you only had big dog and a woodstove in that shop!.............:biggrin:Hey there Ds73 -- A drill press makes the whole operation much simpler. If you fit the stock to the tangs first, you can save some of the precise measuring that Tomray mentions.
With the stock between the tangs: Mark the top hole with a center punch in the center of the tang screw hole. Mark the bottom hole (lower tang) the same way.
Set up a pointed auxiliary center on the press table directly below the chucked drill bit center. Put the center punched lower tang mark on this center. Secure the stock so the drill bit enters the center of the upper punched mark. Support the stock in this position and drill 98% through the stock. Remove the stock and finish the last of the hole by hand.
The picture is of a long stock hole on a project here, but hopefully with the super-imposed stock diagram it will help clarify the process.
