  Print hull components

  Print hull components using 3D-printer. (currently needed printer size: 300*250*450mm
  

  Recommended settings: 3 walls, nozzle diameter 0.6-1.2mm, Z-hop when retracted to avoid layer shift. Raft. Support. Cubic infill pattern. Print one component at a time, to limit time lost in case of print failure.
  

  Closed build volume strongly recommended, due to tendency to warp.

  Produce other hull components

  1. Using miter saw or equivalent, make an appropriate number of metal guide pins. Remember to deburr them for safety and easier assembly.
  2. Cut aluminum profiles to length, and drill holes for mounting to hull ribs.
  3. Cut pieces of metal tube so that they barely reach from the bottom of the hull bow section to the top face of the "tube & servo fixture".
  4. With a turning lathe, make thruster mount axles. (details to come)
  5. Put axle, upper ball bearing, non-toxic water stopping agent and lower journal bearing into metal tube. Stake tube ends to avoid unintended disassembly.
  6. Make thruster mounts.
  7. Using a laser cutter or equivalent, make the top deck of your desired material.

  Assemble hull components

  1. Put some glue in the guide holes on one side of one hull section.
  2. Insert guide pins and let cure.
  3. Put glue on the protruding part of the guide pins and slide on the next hull section.
  4. Apply even pressure until glue cures.
  5. Repeat steps 2, 3, 4, 5 as necessary until your vessel has reached the desired length.
  6. Try inserting nuts in recesses of hull ribs.
  7. If step 7 succeeds, fasten hull ribs to hull.
  8. Using glue, mount metal tube assemblies in hull passthrough holes / tube & servo fixtures.
  9. Cover hull with epoxy resin, or equivalent.
  10. With the current CAD files, you'll have to saw a small gap in the top of the hull to place the aluminum profiles. You will also need to drill two small holes on each bow end to fasten top deck end sections. This will be remedied.
  11. Mount servos.
  12. Mount servo gears.
  13. Mount aluminum profiles to hull.
  14. Mount top deck. (some waterproofing measures are recommended).
  15. Mount thruster mounts.
  16. Mount thrusters.
  17. Mount deck- and electrical equipment of choice.
