I have ordered the book thanks Eastgate

Hi Phil,

Apologies for finding this late. I think that I can help you. I have used this movement in two clocks. One is the mantle clock shown in the second photo in a post I made in this section in July 2009. The other was made 13 years ago. I have made a number of clocks and, these smaller two have the only non pendulum movement I have ever used. I have to admit that they are reliable and can be made to maintain quite accurate time but, without a pendulum have some limitations in time adjustment.

The movement does have a silencing lever. I adapted this to a lever on the rear of one clock to avoid opening the back every time.

The spring escapement has a screw adjuster to time it. Turn clockwise to make slower and anticlockwise to quicken. 60 degrees is approximately 10 seconds per day. One complete turn is approximately one minute per day.

I would oil the movement, simply because you do not know when it was made and oiled.

When oiling the clock

1. Only use special clock oil, NOT light machine oil, etc NOT NOT NOT WD40 or the like. Clock oil is formulated to stay in place and not to run away from where it is placed. You can pick it up on eBay! (eg CLOCK OILER | eBay )

2. Only oil the "oil sinks", that is the small indents where the gear axles (pivots) protrude through the plates. Just a half a drop on the end of a 0.5mm wire, or pin is enough. It will "capillary" down between the pivot and the brass plate and stay there.

3. DON'T oil the actual gears themselves! They are designed to "roll" together rather than "slide" together, so there is very little friction between the cogs. Oil there just attracts dust and causes abrasion, rather than preventing it!

4. DON'T bother oiling lever pivot points, etc. Again, just not necessary.

I hope this helps.

cheers
