Re: Action v: Screw and wingnut
How do you mean? How would you implement the pulley?
I can't think of anything else to put here, so I just wrote this...
Re: Action v: Screw and wingnut
If a pully system is making the threaded rod rotate, then no, these would be parallel.
If the wingnut for example knocks something into a pully system after it has traveled 2 cm, then that would be ok.

Re: Action v: Screw and wingnut
If you use a pulley for the wingnut but dont count it as one of the actions i think it should be fine.can i use this with the pully?

Re: Action v: Screw and wingnut
I'm having trouble moving the wingnut far enough. I have a string wrapped around the screw with a weight attached. When I let the weight go, it rotates the screw and the wingnut moves along, but it only makes it about 1cm before the weight hits bottom.

Re: Action v: Screw and wingnut
Try attaching a big wheel to one end of your screw and wrap the string around that.davidemartin wrote: ↑November 30th, 2019, 8:01 pm I'm having trouble moving the wingnut far enough.

Re: Action v: Screw and wingnut
Thanks for the suggestion. Unfortunately, a big wheel on the end makes it worse. The wheel turns quickly but the screw in the center turns more slowly.

Re: Action v: Screw and wingnut
In order to minimize the weight drop, you need to attach a shaft on the end that is smaller than the screw, which is really tough. Or you could also set up a pulley system with an IMA less than 1.davidemartin wrote: Thanks for the suggestion. Unfortunately, a big wheel on the end makes it worse.

Re: Action v: Screw and wingnut
I ended up using a pulley with IMA of 2 to get enough distance. More complexity, but it works.
