Our front cover features a first place winning clock from the 2000 crafts Competition. This Class 1 (single train clock movement) entry was designed and constructed by Boris Vojvodich (NY) and is a gold plated clock with a simple, single train 8-day, spring wound movement. the principle focus during construction was on achieving an exquisite finish on all parts. During construction, a number of cages were made of perforated PVC material to house the clock parts. the cages were wired internally with wire leads protruding for direct access to the plater, thus preventing the direct touch of shop personnel. Features include ball bearing fitted spring and great wheel arbors; other arbors pivot in carbide bushings ground and honed to a mirror finish. third wheel, escape and pallet arbors have end stones, also made of carbide. To circumvent the hazard of removing the glass dome for winding, the clock is fitted with a winding arbor in its base that is connected to the fusee via a chain mechanism. photo by Jomark Photography. |
