Can anyone tell me what this is? It is made of metal, covered in some kind of fabric and has a nail shaped hook sticking out of the top.

This is a link to it because it wouldn't let me directly upload it.

Thanks in advanced.

OK, they're called "Batten Weights" and are used to hold in place the flexible 'splines' used to layout 'loft' lines on a horizontal drawing board, as shown below:

RE: Unknown Object

Seem to recall they were called "ducks" or some such...

The problem with sloppy work is that the supply FAR EXCEEDS the demand

RE: Unknown Object

Yes, we've called them "ducks" but officially they're 'Batten Weights' although I've also heard them called 'Spline Weights'.

Baker,

Sometimes one is all you need.

RE: Unknown Object

JohnR, never heard a "real" name for them, thanks.

RE: Unknown Object

They give rise to the phrase, " getting all of your ducks in a row." as referred to in Lofting, either in aircraft lofts, or boat yards. Sadly now replaced by a keyboard command . P spline.

You are judged not by what you know, but by what you can do.
