To cut or not to cut?..that is the question

So i cut the majority of the internal timber from the stringer as most wooden board shapers tend to do to help reduce the weight, but after looking at the total amount of weight removed (72grams!!) i wondered if i needed to.... i still got the internal part of the ribs to cut out as well, so i thought i might as well weigh the whole lot once i'm done for future project knowledge...stay tuned for total weight
