Sure. I just put the ends on this so that when it's bent it does not slip off, but ends up pretty close to the ends. Push down on the center and you can feel the spine easily on the heaviest blank around. Unless of course you get one that's perfect and has no spine. Don't see those very often.
I also have the dip in the one end so you can hook the tip inder the wheels and set the other set in the middle of the rod. If you give it a spin, it will stop on the spine every time. That only works for the whole rod.
