Yep, you can do that. Might add some weight though, at least the way I do it (I use this mostly on bigger planes). A piece of 4-40 (cut approx 2") all thread, stuck in to CF arrow shaft with JB Weld (not the fast cure) works great. Just make sure get enough JB in both ends. When you do the 2nd end, it trys to push the other end out so you have to create a temporary air passage with the first 4-40. The link shows one on my big profile. Got this set-up on a few planes now and it's cheap and works great. If you use clevises on both ends, make sure you put a lock nut on at least one of them (4-40 nut tight against clevis) to prevent the rod from turning.
