#WBG001 Wing Bolt Drilling Guide. Installing wing bolts has always required unrealistically good luck. Harry Higley recently developed a new procedure that removes most of the guesswork from this difficult task. It uses this steel guide, which measures 1 1/2" round, 3/4" thick and weighs a hefty six ounces. The guide works for 10-32, 10-24 and 1/4-20 bolts. Your wing will be perfectly aligned, and the bolt holes drilled and tapped with the precision a toolmaker would applaud. The guide comes with step-by-step instructions with sixteen photos showing our his wing mounting procedure in complete detail - along with a few anecdotes that only Harry could tell!
