hi
just want to show off ( youhou ) my first board using vac pump.
it's a mutant, around 150x48 or so, so light wind ( there is no fucking wind here in quebec ).
used 3 times 1/8 inch ply ( baltic birch ) glued and screwed on the rocker table.
used 3 plys cause my inserts are .375 inch and i dont wanted to cut them.
epoxy rail all around.
rails / channels front and back ( real pain in the .....to do, but with a dremel tool ( well, the 14 dollars one from wallmart) ) works good.
one layer of 6 oz glass on the bottom, colored one ( red pigment and grphite powder) plus paste ( epoxy and coloidal silica ) in the rails / channels to seal them cause they delaminated a littlte the plys off wood !
put on vac under 22 inch, hoping to unbag tonight hope the rails are nicely wraped.
BIG mistake : using polyethelene plastic from hardware store instead of special one ( no way to get a slick wrap, i'm going to hav eto sand it after ! ) no way to get it nicely into the channels...
planning on just painting the to side not to ad to mutch stifness ! with my special salt grip.. and colored resin.
