Once the stencils have been created this becomes a easy construction process.
Materials used:
3 off 900 x 600 x 3mm MDF
3 off 900 x 600 x 12mm MDF
1 off PVA wood glue
50 off 10g x 50mm Woodscrews(Self drilling)
Having printed seven copies of the Hull drawing. Carefully create the stensils by cutting and pasting on 3mm MDF. Sand edges to match profile.
Place stencils on desired material you want the hull ribs made from. Ensure a straight edge is used where the ribs are going to be joint the cockpit tub.
For the ribs 12mm MDF was used as its strenght can support any type of skin material I may choose to use in the future. To reduce the weight of the ribs cut out hollow sections and route the edges.
There are fourteen hull
ribs in total. Two are identical for each fuselage station.
Carefully mark out the
fuselage station following the CAD drawing. Each station is 12.5 inches apart. Route a 12.7mm x 0.5mm deep flat groove to locate the ribs for assembly. This will enable the hull ribs to be easily screwed and glued.
Next stage is to fix the consoles.
Incorporating real parts helps to obtain the correct angles.

Back to the ribs. The routed groove can be used as a guide to drill the necessary holes for the woodscrews.
Take the time and care to screw and glue each rib to the port and starboard swinging panel.
Make sure the ribs are square and on the WL91 centre line.
