I would like to know what is the meaning of a "preened wing-nut" in
the context of making a hold down to clamp a piece of wood in a jig.
How to "preen" a wing nut anyway?
I am reading a woodworking book on making jigs. One thing that I am
really interested is making a hold-down with wing-buts, bolts, and
door-stops. If I can make a few of these instead of buying ready-made
hold-downs from stores, I can save quite some money. But one thing
that I don't quite understand in the book is how to secure a wing-nut
at the end of a threaded bolt using "preening".
The hold down as shown in the book is like this:
- A wooden jig has a threaded-through-nut in it.
- An upside-down bolt goes through the threaded-through-nut.
- The head of the upside-down bolt holds a rubber door stop.
- The end of the upside-down bolt has a wing nut on it.
- We are supposed to turn the wing-nut when we want to secure
a piece of wood under the wooden jig. This in turn will turn
the bolt, and the bolt will go down and the rubber door stop
will come in contact with the wood and hold the wood in place.
Obviously, the wing-nut and the bolt will turn independently if they
are not secured together, and we want them to turn together, not
independently. The book seems to say that it can make them to turn
together by "preening" the wing-nut onto the bolt. What does
What's the other alternative besides "preening"?
Thanks in advance for any info.
