Cabin Roof

30mm MID SECTIONS

Weight; 125 Kg for Rear Section

This section is to be made in 6 pieces. The main section is to be done in two sessions. The cabin roof has been extended by 100mm aft to allow the supporting beams to be used as guides for a height adjustable swim platform. The Aft section of the roof has a stiffening beam down the centreline & we have also placed one across the back.A 32mm conduit has been cut into the centre beam for electrical wiring later in the build.A smaller conduit has been added to the cross beam 50mm in from the back edge. the wiring is for a winch for raising the swim platform,cockpit lights on centreline & under rear thickening, navigation stern light & 2 aft flood lights

. The photos show the conduits extending out of the panel to be wrapped around by the nylon film. The cut out on the side is the 600mm by 800mm access hatch to the upper deck. The surrounding gutter is made using 15mm * 20mm timber including 75mm radiused corners. The outer skin is wrapped up & over the timber jig & the inner skin is just laid over the jig.All rebates are double sided. Below is the infusion setup for this panel.

Weight; 100 Kg for Front Section

The photos below show the front section of the cabin roof. The conduit & stiffener beam are extended 2 metres into the front section to finish at the bedroom doorways. The conduit will join up with the one in the back section. We have reduced the number of infusion tubes to 5. This worked quite successfully.

SIDE SECTIONS

Weight ; 60kg for 2 front sections

These sections are back to 20mm foam.Fishing line was used to hold the resin tubes straight. The line sealed easily through the tacky tape. Infusion went evenly across the panel with no problems.Weight ; 44 kg for 2 rear sections.

When the Cabin Roof is assembled a conduit will be glassed around the edge to form a gutter.CURVED FRONT CORNERS REQUIRE BENDING

Weight ; 15 kg for 2 front corners

These 2 panels have been infused with only the outside skin.as they have to be curved later to join the side panels to the downward sloping front section of the middle panel. Both panels were infused together with the short straight sides together.The set up was having the resin line set up around the curved edge on the table with shade cloth touching the foam. The vacuum line was set up on the table as normal at the centre of the junction of the two joining straight edges about 1 metre in length. The scored surface of the foam was places on the under side. The dark circles are where the resin has come up through the holes in the panel. The resin had a distance of 1 metre to travel at the widest point. By shortening the vacuum line the resin from the 2 ends of the resin line had further to travel to reach the vacuum line. The infusion took 3 minutes and worked perfectly. Forgot to get a photo of the set up.I think this set up will work well for the lower section of the hulls as the resin traveled well under the foam.
