To date, this project is on hold for manufacturing | |||
* Workshop <br> Determination of the workshop for manufacturing: | |||
: This project is considered as belonging to the group of Appropriate Technologies, for which it has been developed with the intention of the greatest possible access to processes and materials by the developers, with a basic, moderately equipped workshop, however, it is necessary also have the following facilities: | |||
:: * Tools and materials for working with polyester resins | |||
:: * Tools for carving wood, in the case of blades | |||
:: * Adequate spaces, tools and equipment to carry out electrical work, in the case of generator connections and the associated electrical network | |||
: Although these conditions do not pose a greater difficulty during manufacturing, it is left to the developer's discretion to choose between carrying out this work or requesting the services of a third party to guarantee a professional work | |||
The purchasing, prototype manufacturing, testing, and documentation updating sub-processes, will be developed once the manufacturing stage is completed | |||

** Lateral slack: Apply moderate force on the lever, from left to right and vice versa, alternately. The plates do not tilt | |||
** Example of real use: Making cuts of the samples of plate and sheet | |||
** Visual detail of the cut: Straight shape of the cut, Straight edge, no burrs | |||
<div style="margin:110px"></div> | |||
* Updates of technical documentation <br> Updates of plans, parts lists, assembly instructions: | |||
** 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 | |||
** Mobile blade (piece 2.7), with dimensions adjusted according to the leaf spring piece achieved, recovered material | |||
