I've made RR's from fiberglass driveway markers a time or three, but wooden RR's look a lot better.
Please remember to take care when using your RR, as turned dowels can split out on the side, when a grain runs out - and stab your palm.
I know I may be preaching to the choir, but the best wood RR's are made the same way you did that one, but from split Hickory.
FWIW, after the ends are attached (epoxy) & pinned, my wood RR's get a 30-day kerosene bath in a 3' long section of 1/2" PVC pipe, capped solid on one end, with a loose cap on top.
I've never had a deer shy from kerosene odor, but when the kero evaporates in a few days, there's no odor that's discernable to me. (YMMV)
The most laughable RR's to me are those very flexible plastic (?) RR's issues by some gunmakers (mostly in-lines).
