I'm wanting to add a bead to be aprons of a nightstand I'm working on. I'm relatively new to woodworking and have yet to attempt any projects with a bead component. I thought I would give it a try. I know I have some options: dedicated bead planes (old fixer uppers and some new makers), dedicated beading tools from premium makers (LV and LN), scratch stock, as well as beading blades for a plow plane (I currently own a 2017 LV small plow plane). I know there are multiple ways to do this, I'm just wondering what recommendations you all have? I don't mind spending money on a dedicated tool if it performs well. What are your thoughts?
As a side question, is 3/8" the most common size? That's what I seem to have seen the most in researching in forums on line.
