Out of little more than idle curiosity, does anyone have a link or a description on how a Bond escapement works ?
Ive done a brief bit of surfing and there's nothing immediately obvious shortof buying a book
!
Thanks

WALLACE.

HERE it is.

That looks like a tricky bit of construction!

Thanks everyone (except possibly Andrew !) - yes, it does look a bit tricky - it was only a thought for a way in the future project.
I remember seeing a photograph of a Bond Astronomical Regulator in a book years ago and it stuck in my mind how 'good looking' it was.
Apparently one went for auction for about half a million dollars so I think home construction may be the only way !

Wallace,

As promised; here are a few links

A, B, C, D, E, F

The example at Liverpool Museum is particularly interesting because of the modifications that were done at the Observatory.

Ahhh.. I've just read it a bit more thoroughly -and I'm not sure it's the one that I'm thinking of.The one I have in mind has a conical penpendulum going around in a circle mounted on the top of the clock - is it the same one as described ?

Wallace,

The conical pendulum is only a minor part of the mechanism.

I have a long case clock at home with this type of escapement it is one of two built by my late father Frank Monk FBHI in the 1970s the other went to a friend of his who made the cases, it is still going and keeps very good time.

If you want any pictures I am quite happy to take them,

I did see the lego YouTube one - it's a little noisier than I was expecting ! I'll go back and read the links more throughly.
Ollie -any photos would be great - possibly a bit much for a first clock for me but then what is life without ambition ? !!

Thanks again to all..

W.

If you can beg borrow or steal a copy of Philip Woodward's My Own Right Time it has an excellent description of the escapement. As well as that it is in my opinion one of the best horological books ever written.

I will Second that

Edit: MORT is a superb compilation of Woodward's contributions to the Horological Journal.   When it was published, there was supposed to be a DVD of illustrations, to follow ... unfortunately, this was never issued.

Sincere apologies ... Please ignore the edit in my previous post.

That comment refers to another book: "Woodward on Time"

Wallace,

My copy of "Antiquarian Horology" arrived today.

In their note regarding the forthcoming Symposium "Time for Everyone" they mention this video, which includes some excellent close-up of he Bond Escapement in action.
