Preview: Three Tricks of the Rigging Trade
September 30, 2012
Use of Drill Taps:
Rigging modern boats with metal spars entails a whole lot of drilling and tapping, usually into aluminum. Riveting is an option, and is very attractive from a profitability standpoint, but machine screws are stronger in both tension and shear, and are removable for inspection or for replacing hardware. But drilling and tappingfor machine screws can take a whole lot more time and skill. I can’t do anything about the need for skill, but I can recommend a way to save time by using a combination drill bit and tap, so you do both operations in a single shot. No more finding the right sized bit, then drilling, then switching to a tap.
