Unrepentant Canoeist
I came up with this neat trick while working on composite canoes, but it seems like it would be quite appropriate for real canoes, too. And maybe other folks are already doing this, but I don’t recall hearing of this, and it seems pretty handy.
The issue I’ve had has been driving screws into inwales & outwales. A regular screwdriver doesn’t provide enough torque to be comfortable after the first 15 or 20 screws, leaving about 40 or 45 left to go. Driving with a power tool resulted in cracked rails, which is not pretty.
Lee Valley Tools used to sell an adapter for a ratchet, but I couldn’t find it on their site. Turns out it’s now available at auto parts stores, under different brand names: Titan Finger Grip Drivers, Toolworks Thumb Ratchet, and probably others. It looks like the exact same thing, only it’s a set of three, all the same size; see attached image. Don’t ask me why you need three of the same size.
The adapter fits onto a ¼” drive ratchet, and your driver tip fits in its other end. I hold the ratchet arm, and use the thumb wheel to start the screw (pilot holes, of course), then when I start feeling some bite on the threads, I use the ratchet to drive it home, slowly. The best part is, you can feel when the screw bottoms out in the countersink, so you know when to stop, and the rails don’t end up cracked.
Like I said, maybe some folks already know this... but I was impressed!
