When you drill for pillars, do you use a jig or can they be free handed ok and trued up when epoxied into place?
Using "stud" bolts in the action that are wrapped with tape to just fit into the pillars, will center the oversize holes in the pillars so that the action screws will also center up nicely.When you drill for pillars, do you use a jig or can they be free handed ok and trued up when epoxied into place?
Thanks. That link is worth a lot.....never seen those before.Correct way to do this is a piloted counterbore- and it will run true enough by hand in a drill (due to the pilot) for good results.
Select a snug-fitting pilot to match the size of the holes for the action screws, and the counterbore slightly oversize of the pillar OD to allow room for epoxy.
Best to drill most of the way through from the top, then flip the stock over and finish from the bottom to avoid splitting the bottom wood/fiberglass when running all the way through from the top.
I have actually use lamp nipples for pillars and tapped wood stocks to fit the nipple thread (1/8 NPT). When tapped clear through the threads are loose enough to allow for the epoxy.I do it with regular action screws with release. Definitely oversize the holes so the epoxy has plenty to grab. Even considered running a pipe tap in the holes for a better surface, but never done it.
