"GLASS-FIBRE WOOD CORE" by Van de Stadt Design|
Manual for the new high quality round bilge construction method, using Western Red Cedar battens covered with GRP.
33 Pages with illustrations.
|This building method results in a light and very strong hull.|
|Maintenance is comparable to GRP, the wood core making it extra strong.|
|The core is formed of strip planking laid horizontally over moulds. A lightweight wood with straight grain is the best, e.g. redwood or western red cedar. The planks are glued together and nailed.|
|Once the shell is completed and sanded flat, glass-fibre soaked with resin is applied diagonally. For this process special unidirectional glass fibre roving is necessary of which at least 80% of the strands run in length.A second layer of roving is then brought on at 90 degrees to the first. It is positioned without overlap and is continuous from board to board so that the shell remains fair.|
|The continuous glass-fibre roving leads to an unbelievable strong hull.|
|After the shell has been well sanded and painted, the hull is turned over.|
|All moulds and accessories are removed so that a smooth inside shell is left. Glass-fibre is now applied to the inside with epoxy resin at an angle of 45 degrees. Bulkheads are made using the measurements taken from the moulds.|
