A bit of a helpful video.

  Found this on Youtube.  It is of the Salisbury cathedral clock.  Although it predates the clock I am working on, all the parts are basically the same.  At about the 30 second mark is some good video of the verge and foliot rotating as well as the crown wheel.

More progress...

  Managed to spend more time on the forge today and made some decent progress.  Mainly I was working on the arbor for crown wheel.  Not really anything special about it.  The process was very similar to working on the arbor for the great wheel.  The arbor is mostly formed.  It just needs a bit of touching up.  I will post some pictures of it later.

Progress...

I am attempting to drive to getting the clock to actually ticking so I continued work on the escapement assembly.  Today I made two simple pieces.  The first was an "L" shape at the bottom of the verge and foliot.  This piece has two purposes.  The first is to hold the verge and foliot in place as it comes in contact with the crown wheel.  It is also a bit of a safety feature.  If the wire holding the verge and foliot breaks, this piece helps to keep it from falling through the clock.  It was a pretty simple piece and these pictures show it being made.





This final picture shows it riveted to the frame.  I have the verge and foliot resting in it.



  The next piece is mildly more complicated.  It is a "U" shaped piece of metal.  It is designed to hold one end of the crown wheel arbor.  Because of the placement of the verge and foliot, the end of the crown wheel arbor cannot hook into the frame.  This piece is designed to wrap around the verge and foliot and provide the arbor with someplace to rest.

  I started by rounding the end of a piece of metal.



The center part is then thinned out.



After some more thinning, a hole is punched and drifted to form the hole where the arbor will connect.



The other end is spread out and I punch two holes for rivets.



I give it the "U" shape.



The piece is riveted to the frame.  I used the old arbor from the great wheel to show how it works.  Notice that the end of the arbor goes into the piece rather than the frame.  This allows the verge and foliot to be in its proper positiong.

Perhaps I need to make a marking tool...

  So far, with all of my blacksmithing, I have yet to make a touchmark.  None of the pieces I've made have an identifying mark.  I just came across this article.  http://www.yorkpress.co.uk/news/yorknews/display.var.1280776.0.turning_back_time_to_york_1300.php

It's a nice design.  I could see doing something similar but different enough to not be a copy.  Now, if I only knew someone that knows how to make things like this...  :)

 

The best laid plans...

  Well, I had set aside the entire weekend to work on the clock.  Unfortunately I got the flu on Friday.  I probably picked it up on the airplane.  Anyway, the fever did not break until Sunday evening.  Oh well...  Here's hoping for next weekend.  I am really, really anxious to get back to the clock.  If I can get the crown wheel done soon, the clock could be ticking within a few weeks.

No updates for a few days...

  I am on the road on a business trip at the moment...  So no new updates for a few more days.  However, I am trying to keep this weekend clear (including Friday) so I hope to get in a decent amount of work.  I am going to try and finish the verge and foliot.  This includes some hardware on the frame itself.  Then I would like to get a start of the crown wheel assembly.  I think my goal should be to get a "U" shaped assembly done that holds one end of the crown wheel arbor as well as getting the hole punched on the outside of the frame for the other end of the crown wheel arbor.
