The build starts to come together now, a simple rocker table is formed by securing the assembled spar and rib unit to the cross bracing above the table, this is done in three places, normally nose, centre and tail but add more if you need to or if the rocker is unnatural . The spar and rib assembly is just hot glued to these leveled braces so that it 'hangs there'. The bottom lamination can then be brought up to meet it and supported by shims and spacers underneath it, then 'eye it in', and check for level then pecil mark all the positions of the ribs and down the length of the spar for glue. The glue used in this build is Semperoc v, a D4 class marine glue, very happy with some tests on this product so I decided to give it a go here. The rib and spar area likely to take the greater stance weight and loading are given extra Balsa pads under the ribs, see photo, also an extra balsa spar will be added between the spar and rails later on.
     Ok, glue is on and the bottom panel is lifted and supported in place with shims and spacers so time to step back and check down the line for twist and any wobbles! If all is good clamp up and wait for the glue to cure, for Semperoc rapid this will be about an hour, time for a cup of tea to celebrate!!!!
