      Made in one shot with screw1_5.rb.

      AND it works also with components.

      This is what we call a rope twist not a barley twist. The barley twist has another (interior) radius. The rope twist looks like rope - though your method may work for a barley twist as well. David R's is definitely a barley

          Love your solution but I need to fit it to the other part of my newel. Gilles method looks like it will work. In CAD I'll usually do a sweep of the newel profile then draw my barley twist profile - sweep the barley profile with the correct pitch then subtract it from my newel sweep. I wish I could do it this way (specifically the subtract function) in SU since this yields the most realistic geometry - though again Gilles looks pretty right (just needs more interior radius to be classified as a true barley twist). Thanks

            Its up to you to create the good profile. ๐Ÿ’š

            You can also do this with screw:

              archturn, you could use the method I showed and create the transitions when you've finished. There isn't any reason you couldn't fit it to the rest of the turning. I did on the table legs. The transitions are similar to creating the pommels which I've showed in several other blog posts so I didn't bother with them in that one. The Screw plugin is nice, too. although you can do multiple starts the way Gilles shows, I would still make a single turn as a component and copy it as I did in the blog to keep file size down and make it easier to adjust the length.

                Totally agree with this. ๐Ÿ‘

                    I can see that I should have been visiting the forum more frequently instead of pulling my hair out. Awesome!!!

                      Yes. You should have. ๐Ÿ˜‰ And as I wrote before, there's more than one way to arrive at the final result in SketchUp. This is a great example.

                        I'm wondering how to use the "follow me keep" plugin". I installed it and though it shows up in my plugin menu nothing seems to happen when I click it.

                          You have first to select both the path and the face and then run the plugin.

                            Just a question: why use two plugins instead of one which does very well the job?

                              I'm going to try them all. I remeber some time back trying the "draw helix" without the "follow me keep" tool. That was one of the times I gave up. The result from using the native "follow me" is pretty ugly so I thought I would see what this tool was all about.
                              Again, I wasted a lot of time by not coming here first.

                                screw1_5.rb.

                                select 3 profiles (in the following case), set start point, set end point, enter n steps n turn and go.

                                Could you elaborate on using screw1_5??

                                      Just a quick question. In reality, can you turn a Barley Twist, or is it more of a carving exercise?

                                        Dale, barley twists can be turned, sort of. There's a machine that combines a router with a lathe and gears them together for creating barley twists and other ornamental milling. Check out this link. I used to have one of their machines and used it a lot. Of course now with CNC-driven equipment, it gets even more sophisticated. I can't say I would recommend dealing with the company but the idea was interesting.

                                          Thanks Dave, really interesting machine. I often wish I was a machinist, boy there would be trouble then.

                                            Here are two videos of turning a barley twist and then a rope twist on my machine.
