I purchased the plans, movement and lumber years ago. A variety of moulding planes and other tools accumulated over time, until I decided last fall to tackle this &#8220;bucket list&#8221; project. I have very much enjoyed every minute of the project, even the adventure of acquiring the glass. The result now hangs on the wall between a couple of large bookcases.<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"alignright\"><a href=\"https:\/\/www.bob-easton.com\/blog\/wp-content\/uploads\/2018\/03\/reg-clock-glass-points.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"680\" height=\"510\" src=\"https:\/\/www.bob-easton.com\/blog\/wp-content\/uploads\/2018\/03\/reg-clock-glass-points-680x510.jpg\" alt=\"photo of glass retention using framing points\" class=\"wp-image-6055\" srcset=\"https:\/\/www.bob-easton.com\/blog\/wp-content\/uploads\/2018\/03\/reg-clock-glass-points-680x510.jpg 680w, https:\/\/www.bob-easton.com\/blog\/wp-content\/uploads\/2018\/03\/reg-clock-glass-points-150x113.jpg 150w, https:\/\/www.bob-easton.com\/blog\/wp-content\/uploads\/2018\/03\/reg-clock-glass-points-1200x900.jpg 1200w, https:\/\/www.bob-easton.com\/blog\/wp-content\/uploads\/2018\/03\/reg-clock-glass-points.jpg 1600w\" sizes=\"auto, (max-width: 680px) 100vw, 680px\" \/><\/a><\/figure><\/div>\n\n\n\n<p>The last steps before final assembly were installing the glass. I used framing points to hold the glass in place, and supplemented those with a thin bead of clear silicone caulk to ensure the glass stays where I want it within the openings, and to dampen any tendency to rattle.<\/p>\n\n\n\n<p>Wall mounting uses two screws. The top screw is one intended for plasterboard application and rated for 80 pounds. A single &#8220;hang hole&#8221; in the back board hangs the clock on that screw. A lower screw protrudes from the wall only far enough to fit into a snug slot on the back of the back board. This screw keeps the clock firmly positioned vertically. Mechanical clock movements are sensitive to the vertical axis for keeping the pendulum swinging smoothly.<\/p>\n\n\n\n<p>Total weight is 38 pounds. Those two brass cylinders contain lead weights. Combined they weigh 12 pounds and provide very constant motive power for the time keeping part of the clock. Two chime movements, one for the Westminster quarter-hour melodies, and the other for the hour strikes, are powered by springs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">On being a &#8220;Regulator&#8221;<\/h3>\n\n\n\n<p>We all know mechanical movements are no longer the most accurate time keepers. Electronic crystal regulators surpassed mechanics long ago.<\/p>\n\n\n\n<p>BTW, very few mechanical clocks or watches and the vast majority of electronic crystal regulated timepieces are still not accurate enough to be considered <a href=\"https:\/\/en.wikipedia.org\/wiki\/COSC\">chronometers<\/a>. Chronometer accuracy is critical to determining <a href=\"https:\/\/amzn.to\/2pW88EJ\">longitude<\/a> at sea and is better than -4 to +6 seconds per day.<\/p>\n\n\n\n<p>Accuracy is a relative thing. In the era where mechanical clocks were the only clocks, the Regulator was one of the more accurate. Every jeweler and clock maker kept at least one regulator which they used as the reference for setting all other clocks and watches they touched. The key to the regulator&#8217;s accuracy is the use of a weight driven timekeeping movement. Springs, the normal motive power for mechanical clocks, offer too much variance in behavior: strong when wound tight, weaker as they unwind. Gravity is far more uniform. The gravitational force on the weights provide a uniformity that springs can&#8217;t match. That uniformity gives the clock much of its accuracy.<\/p>\n\n\n\n<p>Even with that uniformity of motion, this clock is not as accurate as a chronometer, no where close to being one. Yet this clock is currently running&nbsp; to +\/- a dozen seconds per day. Regulation is&nbsp;by a small nut that lengthens or shortens the pendulum.<\/p>\n\n\n\n<p><a href=\"https:\/\/www.bob-easton.com\/blog\/2016\/4128\/\">Gratitude:<\/a> hearing the chimes of a mechanical clock&nbsp;&#8211; <a href=\"https:\/\/www.youtube.com\/watch?v=xnI1S5LkxzI\">video<\/a><\/p>\n\n\n\n<figure class=\"wp-block-embed-youtube wp-block-embed is-type-video is-provider-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"regulator clock chimes\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/xnI1S5LkxzI?feature=oembed&#038;rel=0\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n<h2 class=\"wp-block-heading\">Other articles in this series\u2026<\/h2>\n\n\n\n<ul class=\"wp-block-list\"><li><a href=\"\/blog\/regulator-clock-done\/\">Regulator Clock \u2013 Done<\/a><\/li><li><a href=\"\/blog\/regulator-clock-woodworking-completed\/\">Regulator Clock \u2013 Woodworking completed<\/a><\/li><li><a href=\"\/blog\/regulator-clock-scratching-the-frames\/\">Regulator Clock \u2013 Scratching the frames<\/a><\/li><li><a href=\"\/blog\/regulator-clock-door-hinged\/\">Regulator Clock \u2013 Door Hinged<\/a><\/li><li><a href=\"\/blog\/regulator-clock-case-dry-fitted\/\">Regulator Clock \u2013 Case Dry Fitted<\/a><\/li><li><a href=\"\/blog\/jelly-side-down\/\">Regulator Clock \u2013 Jelly Side Down<\/a><\/li><li><a href=\"\/blog\/regulator-clock-case-frames-2\/\">Regulator Clock \u2013 Case Frames &#8211; 2<\/a><\/li><li><a href=\"\/blog\/regulator-clock-glass-2\/\">Regulator Clock \u2013 Glass &#8211; 2<\/a><\/li><li><a href=\"\/blog\/regulator-clock-case-joinery-part-1\/\">Regulator Clock \u2013 Case Frames &#8211; 1<\/a><\/li><li><a href=\"\/blog\/regulator-clock-the-works-work\/\">Regulator Clock \u2013 The Works work<\/a><\/li><li><a href=\"\/blog\/regulator-clock-glass\/\">Regulator Clock \u2013 Glass<\/a><\/li><li><a href=\"\/blog\/regulator-clock-tongue-groove-planes\/\">Regulator Clock \u2013 Tongue &amp; Groove planes<\/a><\/li><li><a href=\"\/blog\/regulator-clock-completed-mouldings\/\">Regulator Clock \u2013 Completed Mouldings<\/a><\/li><li><a href=\"\/blog\/regulator-clock-stick-mouldings\/\">Regulator Clock &#8211; Stick Mouldings<\/a><\/li><li><a href=\"\/blog\/regulator-clock-plate-mouldings\/\">Regulator Clock &#8211; Plate Mouldings<\/a><\/li><li><a href=\"\/blog\/regulator-clock-egg-and-dart-moulding\/\">Regulator Clock &#8211; Egg and Dart Moulding<\/a><\/li><li><a href=\"\/blog\/regulator-clock-eat-dessert-first\/\">Regulator Clock &#8211; Eat Dessert First<\/a><\/li><li><a href=\"\/blog\/jewelers-regulator\/\">Regulator Clock &#8211; original description<\/a><\/li><li><a href=\"\/blog\/jewelers-regulator-stock-prep\/\">Regulator Clock \u2013 Stock Prep<\/a><\/li><li><a href=\"\/blog\/jewelers-regulator-plans-for-moldings\/\">Regulator Clock \u2013 Plans for Moldings<\/a><\/li><li><a href=\"\/blog\/taming-the-rabbet\/\">Taming the Rabbet<\/a><\/li><\/ul>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Ding Dong the Clock is Done!
