Brilliant, thank you Michael. They are a lot neater than mine !

David

Thanks Jeff, yes, I bought a metre of the belt and hot welded it noted the length in case I need another 7 5/8"

Thank you Michael, I don't know anything about ornamental turning. It sounds like a rabbit hole too far

David

Hope this a little clearer?

Sorry Bernard. This is a rig to enable me to cut the internal teeth on a clock which has epicyclic gearing.

It is clamped to the quill of my mill and has a home made cutter driven by a flexible drive from the mill.

Hope this helps.

At the moment, I seem to have a slight twist on it which I'm trying to resolve.

When I mentioned a while ago that I was thinking of starting to build the Strutt epicyclic clock, a few people made suggestions on cutting the internal teeth.

I seem to have combined some if not all the suggestions! This is my attempt, it has yet to be tried as I have a couple of problems to iron out.

Comments/thoughts are welcome as always.

David

Certainly quicker but I have a couple of caveats :-

Don't have the oven too hot and, probably more important,

beware of upsetting the lady of the house as the smell is 'interesting'.

It could be our love of round numbers that makes seem strange.

A mixture of enthusiasm and trepidation at the moment 😊

Thank you Duncan.

Thank you.

David

Steam of course. Hence the clack.

Of course if you could hear it running, you might think otherwise! It is a bit noisy.

David

Double post,

oops!

Finally got around to making a glass dial for the Murday clock I made a couple of years ago. I also added a 'new' base which I thought looked better.

This isn't a wall clock, it's just the photo orientation! I thought I had better mention it first

Moderator Edit: turned the clock clockwise!

Hello Doug,

If someone doesn't reply sooner, I'll find the plans tomorrow and send a photo.

David

I like that a lot, thanks Tim. Not just for the job in question but I can see lots of other times your idea would be helpful.

David

Brilliant answers thank you.

David

As a very new clockmaker, it's time for me to ask what might be a silly question. (It's just as well that I'm old enough not to care)!

I thought that the speed of a pendulum didn't matter because the period remains constant. If this is correct, what is the purpose of the fuseé that I have made for one of John Wilding's clocks?

Many Thanks, David

Are you sure it's the epoxy and not resin from the wood?

David

Here you are Michael,

Precision and accuracy are both terms that are often used in the context of measurement and data analysis, and they refer to different aspects of how well a measurement or calculation represents the true value or intended result.

Accuracy refers to how close a measurement or calculation is to the true or intended value. In other words, it measures how well a measurement reflects reality or how correct a calculation is. For example, if you measure the length of a table with a ruler and get a result of 1.02 meters, but the actual length is 1 meter, your measurement is not accurate.

Precision, on the other hand, refers to how consistent or reproducible a measurement or calculation is. In other words, it measures how well a measurement can be repeated and how consistent the results are. For example, if you measure the length of the same table multiple times with the same ruler and get results of 1.02 meters, 1.03 meters, and 1.01 meters, your measurements are precise but not necessarily accurate.

In summary, accuracy measures how close a measurement or calculation is to the true or intended value, while precision measures how consistent or reproducible a measurement or calculation is.
