Center drilling hole in dowel?

[louie r/c nut]

5/8" is pretty wide what size whole are you looking to make in the rowel .

If it is walking on you you can use a body remer or an ice pick to get it started .

Also it a good idea to use a good wood bit make sure it is sharp this way you can drill slow .

Finding the center is a little tricky I do it mostly by eye you will have to dill a few as test pieces as long as you get it close and make them all the same you should be fine .
