I read Doyle Pugmire’s comment on Jeff Mack Woodturning: Woodturning A Goblet with a Twist (Double Helix) that can be viewed at https://www.youtube.com/watch?v=bl45nkMaYvY&list=WL&index=22 “…When measuring out for the twists, I made it for six one inch increments lengthwise and measured the circumference to be 10 1/2 inches divided it by six to get the distances between squares. This ended up giving me 3 twists instead of two that you did (don’t ask me why).”
Is there a ratio that one should use to determine how many longitudinal (end-to-end) lines/sections vs radial (circumference) lines/sections to use in order to have an esthetically nice looking final project? I am a “fairly new to intermediate” level woodturner and I would like my next project to be a barley twist candle holder…I haven’t decided if the total height will be 6″ or 8″. Let’s say the total height will be 6″ with a diameter of 1.875″ (47.63mm). Having a base height of approximately 1.4″ (35.56mm) and a top section height of approximately 0.9″ (22.86mm) will leave me a middle section of approximately 3.7″ (93.98mm) to make my barley twist…these are approximate measurements from a drawing/picture that I have. How do I determine (1) how many longitudinal lines/sections?, (2) how many radial lines/sections? (3) if it will be a double, triple, etc. helix that I end up with? I have included a picture of a similar candle holder that I would like to make (NOT the goblet from Jeff Mack). Any advice from Jack or any experienced turner would be greatly appreciated. I am new/intermediate but would really like to challenge myself for my next project. Thanks in advance.

There are a couple of forums devoted to specifically to woodturning.You may find your answers there.
There’s a good how-to in this 2007 article:
