    Why did E. Howard paint their marble cases?

    I recently came across an online auction where an E. Howard wall clock was offered. The case was described as painted marble, and the photo showed a white, slightly marbleized (or smudgy) dial. The chapter ring numerals were painted on and a bit faded/worn. I'd attach a photo but the auction...

    A faceless wooden wheel clock from central Europe

    I’m seeking help to identify a somewhat uncommon wooden clock that is missing key pieces to complete the picture. The photos tell most of the story. The clock was obtained out of western Germany where the seller bought it some years before as-is from a collector in southern Germany. Missing...

    British longcase calendars - did "flip" times depend on religions?

    I was exchanging clock observations with a distant friend recently when we got to talking/writing about what hour the calendar would "flip" on British longcase clocks - either 30-hour or 8-day. Wikipedia, under the subject of "Hour", points out how early on days began more often in accordance...

    Anyone recognize this movement, or whole clock for that matter?

    I acquired this wall clock off Italian eBay a month or two ago. Normally I am looking for older clocks, but just liked the look of this one, which I'm thinking may be a 20th century model. Dial is 10" (25.4 cm) in diameter Here are some findings so far: 1. movement has serial number...

    Seeking referral for pivot repair - iron arbor with split

    Help! I am working on my c1720 Quaker birdcage clock and have a pivot split clean through the pivot. I've tackled 2 or 3 re-pivots but this one has me spooked. I had a quick go at removing the old pivot but the metal proved unexpectedly hard. I am assuming then that it is iron and may...

    English Quaker hoop & spike: how'd they make the bob?

    Back in October 2018 at the R O Schmitt Fall auction I acquired an English hoop & spike wall clock. One of the images shows the description. I first saw the auction listing a few weeks in advance and went to the NAWCC library and took out (by mail) Brian Loomes’ “British Clocks Illustrated”...

    Can anyone date this pewter/tin chapter ring?

    Can anyone date this pewter or tin chapter ring? It has unusual markings in the numerals - sorta zipper looking impressions. The ring is divided for a single hand which would usually indicate an older clock, say prior to 1750. But I wonder if the numeral markings indicate a newer period, say...

    Did Riley Whiting use movement "serial numbers" like this?

    I am working on a friend's Riley Whiting long case movement removed from a dilapidated case that is no longer available (except for the bonnet). So there is no label to look at. On the back of the dial and also on the seat board is a series of numbers/letters in faint pencil. As best I can...

    Whiting/Hoadley minute hand retaining method = ??

    I'm working on a tallcase Riley Whiting (Hoadley) movement. The center arbor/minute post is missing 90% of the flats where the minute hand is mounted. I'm wondering if there originally was a square brass sleeve that went over the flats to keep the small square section from being worn down so...

    What is correct size for Riley Whiting tallcase pendulum bob?

    A friend has trusted me to help rebuild the family Riley Whiting movement. Already I am stumped (doesn't take much). It is a movement from a Riley Whiting tallcase, where the lower portion of the case has been discarded after ages in a northern barn. The movement will become a wag-on-wall or...

    Proposed heat & beat repairs of a lantern clock (brass & iron)

    Just received an old lantern clock and a few parts were damaged in shipping. Before I tackle repairs I wanted to run the situations by some other folks with more experience than myself. Here's what I've found so far: 1. brass finial is bent. I would propose to heat the bent area with a...

    What is the best way to coat a polished pewter chapter ring?

    I am in the process of preparing a recently acquired replacement pewter chapter ring for a one-handed clock. It currently has a ring with numerals/divisions for a two-handed clock, so I wanted to get a proper replacement installed. Witness holes in the wood show that the current ring is not...

    Identification of this German or Austrian or Swiss wall clock

    Towards the end of last year I acquired a clock from an antique shop in Austria. Based on the 3 bars in the rear of the movement (3 trains) I thought it was a clock from the Bergland area of Germany (west central area). The seller thought the clock was from west Germany or Switzerland, circa...

    Is this a 'brown wash' wood coating? and how is it done?

    For some time now I've been working on a wooden frame clock. The outer surfaces have what appears to be a brown wash on them. It is lighter than a paint layer but heavier than a stain. In the photo (a work in progress) you can see the difference in the outer surfaces and the inner ones that...

    Seeking advice on translation software and strategies

    I have a growing penchant for European clocks, especially the older (<1740) ones. I try to do research on what I find, but most of the books/magazines/articles are in languages other than English. A few times I've spent hours manually translating portions via Google translations. This is hard...

    Seeking guidance on ST balance and lever system set up

    While cleaning an early (1878) Seth Thomas Ship's Bell clock with platform lever escapement, my latex glove caught on one of the little brass rods that limit travel of the escapement lever. I must have pulled the lower lever out of position a bit as upon re-assembly and test the escape wheel...

    Seeking German or Austrian Uhrmacher with initials VZ circa 1700

    The newest old clock now in the house is a zappler (fast moving pendulum) with a painted iron dial and small brass movement. The rear plate of the movement is engraved with the year 1704 and the initials V Z, presumably the maker. Can anyone suggest a clockmaker (uhrmacher) in Germany or...

    Questions on lube points on new-to-me lathe countershaft & motor

    Recently acquired a used Levin countershaft and motor unit. I'm cleaning them up now and want to renew the lubes but I'm not sure which lube type to use. The countershaft has fittings at each end with a spring-loaded ball in a cap housing over the bronze bearings. Looking inside the bearing I...

    Why did they dish a clock dial?

    Read recently that a tavern clock made in the USA around 1830 had a dished face. What is the advantage of that, especially with heavy iron dials that wouldn't have been easy to dish? If it had to do reflections wouldn't it be negated by flat dial glass? Why not use a convex dial and/or convex...

    Step-train vs Alternate-train: what are they?

    I am reading Paul Foley's "Willard's Patent Time Pieces". In his movement descriptions he used the terms "step-train" and "alternate train", but I can't make out any differences. Can someone elaborate on what they are and why one might be used rather than the other? Thanks, Jim
