John Wilding 3\/4 Second Hipp Clocks<\/h3>\n

These clocks are modelled on a John Wilding design.\u00a0 With most clocks, the power is supplied by either weights or a spring; with the Hipp-toggle clock the pendulum provides the power, as well as regulating the clock.<\/p>\n

\"\"<\/a><\/p>\n

The power comes from a couple of 1.5V batteries, delivered via an electromagnet.<\/p>\n

One deviation from the John Wilding design is the clock dials.\u00a0 I couldn\u2019t decide if I preferred Roman or Arabic numerals, so drew up both on Autocad.\u00a0 They were then photo-etched and delivered to me as etched brass sheets.\u00a0 These were cut and filed to size, sprayed black for the numerals, polished back to brass, silvered and then lacquered.<\/p>\n

\"\"<\/a> \"\"<\/a><\/p>\n

The cases are to my own design.\u00a0 They comprise a backboard and base, wall mounted, and a hood.\u00a0 The hood can be removed for access.<\/p>\n

These clocks can be noisy, so the backboards are19mm veneered MDF.\u00a0 The hoods are composite \u2013 12mm veneered MDF for quietness, with a ply outer for strength.\u00a0 Veneer covers the ply.<\/p>\n

\"\"<\/a>The cases have modest ornamentation \u2013 I didn\u2019t want them to be wholly plain, but I didn\u2019t want them to be too fussy either.\u00a0 The result is a crest-board on top, with a pedestal underneath.\u00a0 The bottom board is profiled so sharp edges are avoided.<\/p>\n

I started out to make one clock, however my workmanship is so bad that I ended up making at least one additional of each component, so it seemed a waste not to make them into a second clock.<\/p>\n
