Plan of Procedure
1. Gather all materials listed in the above tables, and bring them to the working area.
2. Gather all measuring and marking material and bring them to the working area.
3. Measure and mark out, “A” 10 3/8” (See Figure 1 below and Table 3 above).
4. Four lengths of this size are required (repeat three more times).
5. These lengths will than be cut accurately on the band saw.
6. Proceed to measure and mark out “B” 1’-0 1/8” (See Figure 1 below and Table 3 above).
7. Two lengths of this size are required, repeat once.
8. Cut these two lengths using the band saw.
9. Proceed to measure and mark out “C” 2 3/4" (See Figure 1 below and Table 3 above).
10. Six lengths of this size are required so repeat step “9” five additional times.
11. Cut these six lengths of PVC with the band saw.
12. Now all of the pieces that need to be custom cut have been completed the pieces can now be cemented together.
13. First begin with item “E,” (See Figure 1 below and Table 3 above), use the brush in the primer can to spread the primer inside the joint on the top or cap of the of the “Tee.” Do this in a circular motion until the entire inside of the Tee to the first ridge is covered in primer.
14. Do this on both ends of one Tee.
15. No time is required for the primer to sit; after both sides of the top of the Tee have been primed, proceed to apply the PVC cement in the same fashion on both sides of the top of the Tee. NOTE: Do not yet apply primer or cement to the bottom of the Tee, this will be done later in the construction.
16. After the PVC cement has been thoroughly spread on the inside of the top of the Tee, insert “A” (one of the pieces cut out in steps “3” and “4”) as far as the Tee joint will allow the piping to slide. Sometimes a moderate amount of force will be required to ensure that the piece is all the way in.
17. Repeat step “16”on the opposing side of the Tee.
18. Repeat steps “13-17” with the other “E” piece and the two remaining “A” pieces.
19. Begin with one of the “D” pieces and apply primer and than glue to the inside of one side of it as done with piece “E” in steps “13” and “15.”
20. Repeat step “19” on another “D” piece.
21. With two pieces of “D” primed and ready to be bonded with PVC insert piece “B” into the appropriately prepared opening.
22. Take the second prepared “D” piece and push it onto the end of “B” so that it is at the same angle as the other “D” piece and so that one of its openings is facing down like the other “D.”
23. Now repeat steps “18-22” with the remaining “B” and “D” pieces.
24. After these four sets of pieces have been assembled the basic rectangular shape is ready to be assembled for the structure.
25. First prime and cement the insides of the all four “D” pieces.
26. Next insert the one of the “A” pieces into the “D,” while inserting this pipe into the joint make sure that the Tee’s open hole is facing downward in the same way that the open “D” hole is.
27. Repeat step “26” on the other side of this set.
28. Now push the remaining set of the “A” and “D” pieces together with the exposed “A” pieces (as seen in Figure 1).
29. Now let the competed rectangle sit for several minutes until the cement hardens and the joints become inseparable.
30. After the rectangle sets and becomes one piece prime and cement the opening on the two Tees and the four corners.
31. When all six of these openings are prepared insert the “C” pieces (as seen in figure 1).
32. Let these set joints set; when these are solidly joined the assembly is finished for the time being.
33. Now piece “G” must be measured and cut to the appropriate dimensions.
34. Use the band saw to cut the plastic mesh to the proper dimensions.
35. Set the cut plastic mesh inside the rectangular structure.
36. Use zip ties to fasten the hard plastic mesh to the frame.
37. “F” pieces will be permanently cemented on at a later point after the buoyancy measurements are completed and the craft is ready to have the final counter buoyancy weights attached.
