Phllips House in EmleyIn July 2012 Sinclair Harding became proud owners of Phillips House, the building was originally the workshops, pit head baths, medical centre, lamp room and clocking in/out room for Emley Moor Colliery (hence referred to as the Clock Oyle). All hands on deck as Phillips House is currently undergoing conversion to a huge workshop, polishing oyle, packing oyle, and so on . . . .

Its starting to take shape now, partition walls have been removed and the suspended ceilings have been taken down to give more height into the workshop - we've even begun painting. Air benches are on order for the new polishing area which should make a big impact on reducing our dust.

Fusee chain manufacture at Sinclair HardingOur Fusee chain suppliers, Mavis and David decided to retire at Christmas 2013, with nobody coming forward to carry the business on, we agreed to buy their business and in January 2014 collected the first batch of machinery from David's workshop in Devon and moved it to Huddersfield. Over the following few months David and Mavis shared their knowledge acquired over many years and we have been painstakingly learning this almost lost art. This wonderful addition to Sinclair Harding must make us about the most complete clock making company to be found.
