      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.

                                        That's Great. So can you directly import from SketchUp to you machine?
                                        ( Oh and, I guess I'm still living in the past, as I was thinking of how difficult if not impossible to turn it by hand. ๐Ÿ˜ณ )

                                          My machine is not a full CNC but a step below it. It is a hydraulic copier so it traces a profile. The indexing function (used for the twisting) however is computer controlled so the setting up of gears and indexing pins that Dave R referred is not necessary. The templates I use for the turning profile are drawn in CAD and sent to a machine shop with a laser CNC so I can get a pretty fine template for tracing

                                            As for turning by hand, it's not impossible but I wouldn't want to make a living like that.
