Screwcutting on the DB200 and SL1000 was only possible by employing a very old-fashioned (but accurate) system of using Master Thread guides and a "chasing" arrangement; this limited the range of treads to those provided by the maker.

The Master Thread Ring can be seen positioned behind the chuck; the pitch of the master thread was reproduced on the workpiece by a cutting tool sliding along the upper round bar.

Metric threads of: 0.5, 0.6, 0.7, 0.8, 0.9, 1.0, 1.25 and 1.5 mm pitch were available and 16, 18, 20, 22, 24, 26, 28, 30, 32, 36, 40, 48, 50 and 56 t.p.i. For screwcutting very much slower speeds than those normally provided were necessary and Emco offered both a mechanical slow-speed kit (a motor-mount bracket that carried an extra pulley) and electronic speed control of the motor.

If you damage a "Master Thread" check to see if its made of "brass"; if so, you may be able to carefully peel away the spoiled top layer to reveal another set of threads beneath--the unit being made up of layers.
