MikeB_UK ..... my blog is for smaller dowel you use often in joinery and hinges. Typically 1/4" - 3/4" dia.
IMO, a lathe is not practical for small stuff like 1/4". I'm not saying it can't be done but wouldn't be my choice going this route.
I've never used a rounding plane to make dowel. I welcome your input on the blog I posted.
Cheers!
