Depends on the purpose and what tools you have. If you have a lathe just chuck the rod on the lathe, turn it on and hold a pencil to the end. You will either get a dot (the center) or a circle. You can also chuck a pencil or scribe in the tail-stock to make the mark. If you want to drill the center just put a drill bit in a tail-stock chuck.

I have a Starrett square with a center finder attachment. Couldn’t be easier.

Finding the center is one thing. Accurately drilling a hole in that marked location is another. Check Rob Cosman’s jig for this. You can make one for free.

If you are doing this process repeatedly on hundreds of dowels… then make a jig. All you need to do is drill a hole on a board that the dowel can slide through.. not to tight but not too loose.. Then blind one end of the hole using a piece of acrylic plate (this will allow you to see the dowel ends when it is slide through… use screw for fixing the acrylic piece. Finally, on the acrylic piece , drill the center hole for the dowel pin and countersunk it just enough to allow you to insert a marker for the center of the dowel pins. This way you can insert dowels, one at a time to the hole and mark the center of the pins as long as you want without using any rulers or straight edge. Hope this will help.

Grab a forstner of the same diameter and kiss the end of the dowel with the point of the bit.

take a spade bit the same size as the dowel. Drill a hole through a piece of scrap wood so the point of the bit just starts through the back side.
You can now insert the dowel in the opening and mark through the small hole with an awl or pencil.

Google for “Rob Cosman” drilling dowel. I’ll provide the link also but it may go stale over time. http://www.robcosman.com/tools_drilljig.php . His jig is not free, and it only comes in one size. You can make your own in ANY size.
