    Barr & Poole Brillie A Brillie barely hanging on ...

    Hi EscapeWheel, The link you provided discusses the electrical contacts (circled and pointed to in blue below). And they are an important part of the electrical portion of the clock. The part (tooth) I'm interested in is purely mechanical in nature. This tooth rides over the ratchet gear...

    Barr & Poole Brillie A Brillie barely hanging on ...

    Over the years, I've picked up various electro-mechanical 'junkers' for not much money. I pulled out a Brillie from the collection to see what ails it. To start, it was one the most tarnished and gummed up clocks I've come across. The brass was completely black and the gear train did not want...

    Bulle Yet another Bulle controller ...

    Bryan has made some good products. I still use a MicroTimer of his that I purchased some 15+ years ago. I've always wondered why he retracted his controller from the marketplace. Especially when I've heard people say good things about it. I have a feeling that any type of controller offered...

    Bulle Yet another Bulle controller ...

    Hi Frank, I feel like controlling the Bulle is a knife's edge. When everything is just right, it can be done. But even the smallest deviation from a perfect mechanical setup and the controller doesn't stand a chance. And the rachet wheel ... oh don't get me started. Just like you said, if...

    Bulle Yet another Bulle controller ...

    Hi Peter, To answer your questions: 1) My original calculations gave me a +/- 20 sec per month of error that the controller could correct. During development, I'm finding that +/- 15 is more realistic. 2+3) The isochronism spring is a interesting device. Years ago, when I was first...

    Bulle Yet another Bulle controller ...

    As an controls engineer, I just couldn't help but try to devise a controller to regulate my Bulle clocks. Self imposed requirements: 1) It has to be non-intrusive, meaning the clock is not modified in any way (no cutting wires or inserting other devices). The control system connects to the...

    Standard Electric Standard Electric - diodes and power reserve

    From a prior post, I was deciding upon a diode to mitigate arcing on the contacts. I ended up using a Schottky 1N5817, rated at 1A and 20V. My clock seems to run fine on a 12V source, and draws about 0.5A during contact. No more arcing. Now, onto the power reserve of the clock's spring...

    Standard Electric Standard Electric master winding solenoids

    Hi John, Thanks for the correction. The first suggested diode did seem a bit overkill :) As to the sparking, I'll admit that I took the most dramatic example to post. The amount of arcing has become substantially less as the clock has been running. I suspect the initial bright arcing was a...

    Standard Electric Standard Electric master winding solenoids

    Hi John, I've got the clock to run, not optimally, but running. 18V seems to be what the electro-magnet needs to advance the winding mechanism. As you can see from the video below, I have an arcing issue. I agree that a free wheel diode should solve the problem. I'd like to ask why you...

    Standard Electric Standard Electric master winding solenoids

    Hi John, Sorry to have disappeared for a couple of weeks. Sometimes the clocks have to take a back seat to family/business/etc. Thanks for all the info you have posted. I've come to realize that I have had fundamental misunderstanding about the electrical winding mechanism. I thought the...

    Standard Electric Standard Electric master winding solenoids

    Hi John, Thank you for all the information that you have provided. Between the links, videos, and forum information, I think I have a good understanding of the clock. And all this information has made me realize that I have bought a very tired clock. But no worries, its good to start with a...

    Standard Electric Standard Electric master winding solenoids

    I've taken the solenoid assembly out of the clock. Now that its in hand, and more easily studied, I see that the solenoids are wired in series. Originally, I had thought they were in parallel ( I don't why I thought this and I be wrong). The impedance is around 40 ohms. I've tested them with...

    Standard Electric Standard Electric master winding solenoids

    Thank you for all the information links and your detailed commentary! I know it took you some time to put together a reply like this. I plan on removing the solenoids today to check them out. Your advice about noting the gauge and # of winds is well taken. Rewinding them shouldn't be too...

    Another observation is the discoloration on the brass plate right above the solenoid. This solenoid must have gotten really hot.

    Standard Electric Standard Electric master winding solenoids

    Hi Everybody, I recently picked up a Standard Electric master clock, which has had a hard life - much evidence of many prior hands being in there, so I'm starting from ground zero. When manually wound, the clock will run nicely for 30+ minutes. The 1 minute pulse contact is working -...

    Bulle Pendulum bob holder

    Maybe not too exciting to others, but I've never seen this before. Its looks like an original factor pendulum bob holder. Maybe this is how the factory shipped them out when new? I don't know. I use clothes pins. I'm tempted to buy the clock just to get the holder.

    Bulle Naked Bulle

    I realized that the parts stash had enough parts to cobble together ... well something. I mounted it on some scrap wood that I got from my carpenter neighbor. Routed out a place for a AA battery on the back and it hangs flush to the wall. Visitors seem to get a kick out if because it doesn't...

    Bulle insulation washer on the fork assembly

    What is the purpose of the washer shown below? It looks to be made out of an electrical insulation material but is not serving an insulating role. And I'm having a hard time envisioning a mechanical role for it. I've been playing with Bulle's for years and just today wondered what the purpose...

    Brillie A modified Brillie: abomidation or creation?

    Yes! I felt there was some sort of miscommunication going on here but not quite sure the cause. Maybe 'abomination' was too strong of a word. A more straightforward title would have been: "A modified Brillie: do you like it or not?" And then those interested, could chime in whether or not...
