Looks good Jerry, When I do deck work I bend the balsa core over a piece of large PVC pipe and wet out the scribes in the balsa. In my mind I think it will make the deck stiffer and if it should leak at some time in the future it will slow down the spread of water. Do you see any benefit to my method? Yes it is a great time of the year to be doing this type of work, that 100 degree stuff was just too much.
