for those of you wondering what the inside of your hollow sounding stringer might look like, heres a pic.
this was all caused by the manufacturer not sealing the hole drilled through the stringer at the end for drainthrough.
Thats what mine would look like if they were opened up, I'd imagine....:jawdrop: Ugh.....
Oh damn!!! Thats NOT good by any means
I remember drilling a hole in mine and water ran out Not a good feeling
