Micrometer Centring Tool - Ref.  JMW1588

Designed to be used in the 8mm Watchmakers Lathe for centring the wheel and pinion cutter to the work, particularly when cutting small pinions. If not exactly central, leaning teeth or leaves will result. This tool takes all the guess work out of the process.

Mainspring Length Gauge JMW 1082

Mainspring Length Gauge JMW 1082

The length of a clock mainspring is extremely important for the correct functioning of the clock and to give the correct number of turns of the barrel. This gauge will determine the correct length for a given barrel diameter without any need to carry out any calculations. The method is quite ingenious and the tool was designed by Bill Smith of America, who received a Gold Medal for its design.

Micrometer Centreing Device JMW 758

Micrometer Centreing Device JMW 758

The centreing of the cutter to the work when wheel and pinion cutting is carried out is not an easy operation, unless the cutter is at the exact centre line, particularly on pinions the result will be leaning teeth or leaves. There are a number of traditional methods used, all of which rely on guesswork. The Micrometer Centreing Device will ensure the cutter is on dead-centre every time.

See book 'Clock Wheel & Pinion Cutting'.
