This construction manual is very extensive. It demonstrates all essential steps for the manufacturing of the LAZOLA Solar Cooker. The cooker can be built in two sizes: standard width (Ls) and double width (Lw). Every single step will be explained in this manual.
The LAZOLA building manual differs from other instructions on building solar cookers:
  • Not only does it tell what must be done, but it shows in every detail how it is done. Every video clip can be reached with a single click.
  • For every part of the cooker paper templates with all necessary information on cuts, holes etc. on a one to one scale are provided.
  • As in every serial production all steps are structured and specified. Thus the building process will be time-saving and fail-proof.
  • This requires the measurements of all small parts like screws, washers, rivets etc. being exactly as given. All screws etc. are made from stainless steel. As these parts won’t be readily available in the countries the LAZOLA cooker is supposed to be built in, the LAZOLA initiative offers to supply them at a reasonable and cost saving price.
  • Many work steps require certain production aids (jigs) that can be obtained from LAZOLA.

    Small things make perfection, but perfection is no small thing.
