Thinking about combining the three items in the pictures below to create a homemade fish scale/measuring tool. Essentially a tray with a sewing mat cut to fit and glued in the bottom that can be placed on a kitchen scale. The whole think should cost less than $30. Has anyone done anything like this? Think it will work? What should I do differently?
I realize that if I catch a fish that weighs more than 11 lbs the scale won't be big enough or if I catch one longer than 16" my tray won't be big enough but I think I am well within those bounds for a few years.
