Issue 10, stage 5 of the Launch build and adding the final Keel section.
Lightly sand the edges of the frame parts being careful not to alter the shape, carefully store mast support #6.
Install the final Keel section as per the Steps, (it is very imortant that the entire length of the keel runs perfectly straight), ensure that neither Brace encroach into the slot/frame space ether side of the Keel joint, and that both braces are level with the top of the Keel.
Don't glue any of the frames into the Keel at this point.
Continuing with the Launch build, the inside of the hull should be painted before adding the Floorboards, Duckboards and Thwart supports, you'll need the 1x3mm strips, 0.6x3mm strips, 2x mesh grids (Duckboards,) and the mast supplied within issue 9.
If you've opted for the painted finish, you should paint the Floorboards before assembly.
The Floorboard section is made up from nine 1x3mm wood strips, cut four boards to length as shown in the photo, the central board is laid in two sections, the gap between the two sections is for Mast location, trial fit the mast for a snug fit, when happy glue the boards into place, and as you progress to the outer you'll need to shape the outer boards to suit the curve of the hull.
Fitting the Thwart rails, these are made from two 0.6x3mm strips, again if you've opted for the painted finish these should be painted before placement. Cut each strip to length and glue at each frame contact point.
Fitting of the Duckboards, mark around the two Duckboards onto paper which will be used as a cutting template, cut the paper to shape. Trial fit the temoplates into the Launch, carefully mark and cut the paper where necessary, then lay each Duckboard onto the templates and cut the Duckboards to shape, check the fit and then paint both metallic black, though apply the paint thinly to avoid clogging the grids, when dry glue both Duckboards into the Launch.
