Cold Moulded Timber
TIMBER LIST FOR HULL, DECK & BULKHEADS
The following timber list is for construction of all structural timberwork for hull, deck, bulkheads, engine beds, keel deadwood and skeg. Allowance has been made for reasonable wastage and scarphing. Large timbers can be laminated from smaller sections if necessary. Timber is to be selected, free of knots, shakes fractures etc
Construction detailing is for strip plank followed by two layers of diagonal veneers over the outside.
Building stocks and temporary timberwork are not included. Note that this hull must be built over temporary male station formers, not over permanent bulkheads. This temporary timberwork can be made from any stable low cost timber. |
