I'm getting ready to s&g the keel of my first kayak ever, I can figure out how to stitch it & how to glue it, but I still don't know how will I be able to mesure it's simmetricity. In other words: I want to make sure the keel is simmetric before gluing it. I'm sure it will not be simmetric on the first shot, it's my first kayak, & I'm not that perfect. I will be able to fix it if I'll be able to measure it.

any help appreciated.
