Ok so getting further on with the project, have been chambering the sections which take about 45mins a piece.
I was a bit worried about my lack of clamps and trying to glue back together to many sections at once so i am doing it in stages.
Chambered the 6 center pieces and glued them up. next done 3 more either side as sections 2 and 3. leaving 3 more outer strips on the left and right outside, the outer 2 are to small to chamber so will only have to do one of each side of that section.
then will glue the up as a 3/6/3 then finally a 3/363/3 if that makes sence
The chambering has taken more weight out than i though, weigh the center 6 section and one of the 3's and it only came to 3.5lbs so i;m guessing a 7 to 9lbs
I guess you could also use a rasp, to make all the inside even to make it even lighter, but i dont think it worth the extra work.
I am considering marine varnishing the inside before it goes together as a sealer, any opinions on that?
