Since my 47 year old mechanical school clock<\/a> left home, there’s been an empty spot on the wall where eyes land several times a day, finding little but a faded outline and silence. It’s time to change that.<\/p>\n\n\n\n

\"Jeweler's<\/a><\/figure><\/div>\n\n\n\n

Back when clocks and watches actually had mechanical things inside, watchmakers and watch repairers (often jewelers) needed an accurate timepiece from which to set and check times. “Regulators” were accurate enough, probably not quite as accurate as H4<\/a>, or other chronographs used for navigation, but close.<\/p>\n\n\n\n

Many case styles exist for regulators. Two of my favorites are movements with longer pendulums, the Vienna Regulator<\/a> and the Jeweler’s Regulator<\/a>. Here we have a Jeweler’s Regulator that has been offered for many years by Klockit<\/a>. I’ve admired it for as many years, keeping it on my bucket list as one of the clocks I want to build. Nope! I am NOT building a kit. Klockit offers drawings for this clock, 8 large sheets. I’m working from those drawings and using some Cherry that I bought last year. However, I will be using the mechanical movement components the clock was designed around, a Hermle regulator movement. When I built that school clock 47 years ago, mechanical movements were very plentiful and reasonably affordable. That was a decade and a half before the rise of quartz movements. The transition to quartz is now nearly complete and mechanical movements are becoming rarities. Demand has fallen, resulting naturally in fewer choices and dramatically higher prices.  So, I caught this one during a 20% discount sale before its cost escalated yet more.<\/p>\n\n\n\n

Rarely do I build from plans. In this case, I’ll stick close to the plan but will make some alterations, specifically to allow some carving. At the moment, I’m thinking the biggest change will be replacing the dentil molding<\/a> in the crown with egg and dart<\/a>. Maybe more…<\/p>\n\n\n\n

In any case, we now see the reason I jumped on that set of hollows and rounds<\/a> a while back. They were bought for clock moldings. Learning curves ahead…<\/p>\n\n\n\n
