** Lateral slack: Apply moderate force on the lever, from left to right and vice versa, alternately. The plates do not tilt | |||
* Updates of technical documentation | ** Example of real use: Making cuts of the samples of plate and sheet | ||

** The main plates (2.1 to 2.3) were manufactured in a thickness of 12mm, which is sufficient, instead of the 16mm initially proposed | |||
** Modification in the length of the bushings, according to the new plate thicknesses | |||
** Pieces 2.5 and 2.6, manufactured in 1/2" square bar, available in the workshop | |||
