The old fishing reel line winder. You have to share this design with us. Maybe a longer screw action. I do not have a project in mind but have been thinking about this reversing screw for a few years. Thank you for sharing your build with us.
Yes it is John! It's also a mechanism similar to the old high speed dot matrix 2d printers. I'll finalize some issues with the model and publish them. Greg
When the factory I worked for bought new cnc lathes, an application engineer came down to help set them up and train us on the programming and running of the lathes. He told me he went to Florida to set up some lathes to make this part that was used in fishing rods. I think he said it took a couple of weeks and many 12 foot bars of brass stock to get the spiral part right. The engineers in Japan, they were Citizen Swiss type lathes, said the machines weren't capable of making the part but he figured it out. The lathes were replacing screw machines, Browne and Sharpe, if I remember right. It took some serious brain power to design machine tooling for the screw machines to make that part. In the past I've searched for info on making this part but haven't found much. It would be very useful in winding operations. I would love to see how you designed the part in Fusion 360.
Slap in two of these together arranged vertically and synced and you'll have a nice diorama of the goal tape from Super Mario World. I tried designing something like that earlier last year but couldn't quite figure out a reliable design.
Thank you MoAvW, I'm glad you enjoyed it and you're very welcome! The design of the traveler is such that the traveler tail is long enough to keep the travel nose straight through the intersections, but short enough to make the turnarounds. Greg
Thanks GrandadsOtherChannel, like John from Robothut, I've been thinking about designing and 3D printing this mechanism for awhile and finally found time to accomplish it. Greg
Hi bixbybill3342, I used this model in the following three mechanisms: www.instructables.com/Self-Reversing-Screw-Mechanism-Walking/ www.instructables.com/Self-Reversing-Screw-Mechanism-Slinky/ www.instructables.com/Marblevator-Reversing-Screw-Lift/ Hope that helps! Greg

Very useful for a filament respooler. Similar to what bambu ams needs.
Well I did not think of that, but it's a great idea!
Greg
I’ve seen it used for such .. anywhere you need to coil wire.. such as copper cores for motors, etc.@@popzct

Well that would work, and I did not think of that!
Greg
Awesome. Curious to see where this end up being used... looking forward for the follow-up videos.
Thanks rodirob, I truly appreciate it!
Greg
I know I'm going to use it somewhere. Thanks for sharing! How did you make sure that the traveler won't catch its tooth in the between transition?
Thank you MoAvW, I'm glad you enjoyed it and you're very welcome!

That is fascinating 🤔👍

Very nice.
Thanks again MicrobyteAlan, I always appreciate your support!
Greg
where can i get the STL for this?
Here's one: www.instructables.com/Self-Reversing-Screw-Mechanism-Walking/

hello, I would like to download the stl files, where can I get them
thank
