Sallaz Miniature Tapping Machine and
Precision Drill Press Type KDFFO
Typical of its type with two pulleys, one for drive the threading tap downwards and the other to withdraw it, the first set of pictures shows a Sallax tapper made by Gebruder Sallaz Aktiengesellsschaft in Switzerland (Aktiengesellschaft Swiss Germanis just a word for 'limited company'). Sallaz also made a variety of high-class machines for watch and instrument manufacture. Unfortunately, the drive system of the tapper that rotated the pulleys (by using a round belt) is missing.
The lift of the tap appears to by be a weight attached to the operating arm; pressing the arm down engages downward drive pulley; releasing the lever allows weight to lift the arm, engage the reverse pulley and allow the tap to be unscrewed.
Both machines on this page - and the Luthy precision drill press shown here - are believed to have been used in the Bolivia watch factory once located in Queens NY; the evidence being that a Bolivia bench micrometer both came, originally, from the same USA seller.
Other makers of small tappers of the same type include Aciera, Dowling, Oldak,
Essex, Herke, Schaublin, and Wiest.
Shown below the tapper is a miniature precision drill press by Sallaz, this having its original variable-speed 3-phase motor.
Other lightweight drill presses and similar models include Aciera, Cameron, Baby Grand, Champion, Baldwin, Dixi, Dumore, Hamilton, Hauser, IME, Luthy, Meepos, Micromeccanica, Oldak and Apex, Paco, Progress No.10, Ruka, Schaublin, Sher and WA-CO..
