Sztrandek - documentation
Sztrandek documentation.
         For all who want to build the Sztrandek just for himself, the documentation is for free. Everybody can print it from the web site. If the builder wants the Sztrandek to register, then he may need the licence. I can send the licence by mail if someone wants it and if someone sends me the photos of a building boat in the first place. I wil place them on my web. The photos will be useful for another builders. They will have a chance to see on the photos how to do that, maybe get some help and it will be easier for them.

Comment: 
  1. In anticipation of tough utilization, it is better to use marine plywood  8 mm. 
  2. Sticking should be realized on the set up patterns, placed on the assembly base.. 
  3. In the middle layer cut the hole and fill in with lead according to sheet nr. 21, 22.
