I have a few other questions. I'm building a simple boat (cajun flat bottom 10 feet) as a starter project. The points of the bottom are plotted on a piece of plywood. What would i use to make a smooth curve? Do you use a hand held jig saw to cut it out? I want to put a fancy deck on it. Would a hardwood veneer plywood be ok? I'm not sure if it is rated for exterior use. Other material to use? 1/4 inch ply is that equivalent to 6mm. Is 5.2 mm luan too thin for sides and deck. Can i join plywood by a butt joint and a 1x 2 across the joint on the interior. All my materials are to be bought from a home depot type store. Looking for inexpensive ??? Scout around for Doug Fir "CD Plug & touch sand, Ext" ... HD ?mite? have it ... a good contractor yard for sure ... or ... 5/16 CD Ext ... usually 3 plys of 1/10" veneer , a good, balanced construct. Better yet .. BC 5/16" or 3/8" Ext ... concrete form ... source = a specialty lbr yard Doug Fir is great sftwd 'veneer' ... "else" is far less so . Plywood Butt joints dont 'cut' it for 'structures' that mite flex ... even with a 'lap' piece . marine plywood 'splices' are made with a scarf joint ... slope 1/12 min , lotsa heat/pressure & ext resin glue Only 8' sheets available ??... build an 8' boat if you cant find 10' sheets. Go for a "3 ply" lamination construction ... .. 3 plys of 1/8" or 1/10" veneer avoid anything with a 3/16" thick 'core' ( ctr ply ) ... avoid 'sanded' ... go for UN_sanded ... the strength is in the face/back ply. Dont splurge on hdwd 'cosmetic' plywood constructions ... ie .. thin face veneer ... go for a =thick= face & back veneer ... Annular ring nails(cheap) work well for construction ... "buggle" screws tend to 'work' & 'pull' the head out ... Paint it, keep it on mostly the hard ... Ed. |
