    Excellent video on joints. I think I even understood enough to ask a question. Is there an advantage to making the rigid joint between the indexing wheel and the shaft (17:30) over a rigid joint between the indexing wheel and the shaft-key joint?

      @ArnoldRowntreeTeachesFusion360  4 года назад +1

      Thanks Zachary, I did spend a few moments pondering that when I was making it and decided on the spur of the moment that I'd focus on the wheel to shaft joint because the function of the pin is only to stop slippage and reinforce the interference fit between those two main parts.

    Aww look at those cute kangaroos in your backyard!! Haha here in the US suburbs, we see sometimes see deer in our yard instead of kangaroos! 😂Anyways, another amazing series Prof Rowntree! I'm learning so much from you! Thank you again!

      We have some feral deer nearby too but they are much more discreet - they need to be since they are known to be delicious.
      Thanks for your kind words, I'll keep going.

    Awesome, epic. Great video. Seemed overwhelming at first but step by step done 3 times over while understanding it. Its a sinch (; I'm not sure if I got the angle in between the 2 construction lines. My pin seems to be butting the Geneva mechanism and not revolving smoothly.
    Imagine, kangys in your backyard- the life😃

      The kangaroos can be a bit of a distraction.
      If you've worked through this several time you've learned quite a lot. At least you understand the steps even if there's glitchy movement. The idea is that when you come to trying out your own designs or a modification of another Grabcad model, you know how things are supposed to work. That's a big step toward your goal. You may be needing help for a while yet but you're well on the way.

    Very good delivery. Enjoyed learning from you. My only question during the development was how you knew 37 mm was the right distance to place the pin on the driving wheel. Seems that placing two construction circles for the two sides lobes of the slot entry and then averaging their radiuses would get you the proper distance. But perhaps there is an engineering design approach.

    • @ArnoldRowntreeTeachesFusion360
      @ArnoldRowntreeTeachesFusion360  4 года назад

      Good question Gordon, my first attempt caused a glitch in the animation when the pin bumped its way into the slot. I looked a bit more closely and made one adjustment, didn't write down the details or the thought process and can't remember now. My purpose was simply to make a model that animated (nothing like an engineering approach).

    Great tutorial! I like to follow along as you build. I did run into a problem with the animation. I followed you to the letter on the joints but for some reason the pin stops at the entrance to the slots periodically and the key loses it joint and then snaps back into place when rotating the drive wheel. Is there something I need to adjust to prevent this?

    • @ArnoldRowntreeTeachesFusion360
      @ArnoldRowntreeTeachesFusion360  3 года назад

      V4t, I wish I could be looking over your shoulder, there are many things that can cause the animation to fall over. Fusion is calculating large number of alternative scenarios with the geometry and angles within the contact set. What I'd be doing is checking the sketch and the extrusion extents, any variation in size can lead to an interference between the selected components.
      Since its good to repeat the exercises, its probably better to repeat it carefully than to check over all the details. Your call.

  • @jenspetersen5865
    @jenspetersen5865 4 года назад +1

    Great advice - there is one thing though that I do not like in your process and that is that your are not tying things to the origio points - the Z azis really should be through the Geneva wheel, so that the Z axis was common for parts attached to that rotation.
    In larger assemblies it is invaluable to have common centerlines, and it is one of the things that are really cumbersome when you import from other sources.

      @@ArnoldRowntreeTeachesFusion360 One other thing I would love for you to take up - a thing that I have a hard time figuring out in Fusion is constraining in the assembly space. In the sketch environment it looks totally like other CAD packages, but I am spending way too much time on doing the same with bodies - lets say an imported body that is designed at a 5 degree angle that you want to align to the x, y, z grid.

    My biggest problem is some bodies are part of other bodies that should not be. I have to be more aware of "new componant" vs join etc.. I think that is where I am getting in trouble. Spent a lot of time trying to seperate bodies and combine with other bodies to come up with the same components as you. Learning is so frustrating sometimes.

      I'm glad to see you're still going on with my tutorials Joseph. This is the intermediate series you're in now and there's a lot going on. Did you do the 'Bodies and Components' playlist before this one? I'm going to be building that out quite a bit when I've caught up on the revisions since its so foundational to these intermediate level tutorials. There is quite a bit of self discipline needed to keep the browser nice and tidy. Thankfully you can usually re-organise it as I demonstrate in the 'Bodies and Components' tutorials.

      Hi Harley, the hand crank we made in this series probably looks far too basic for you now. It will be a while before I go in-depth on modelling, I want to cover more of the broad areas of Fusion 360 but we'll get there.

  • @OLLE3770
    @OLLE3770 4 года назад

    If I use your method of creating a rigid joint between the BASE and "top level" the KEY does not rotate with the SHAFT during animation. If I instead "ground" the BASE, the KEY will rotate with the SHAFT. Is this a bug? Why are you not using "ground"? Other tutorials on joints uses "ground". I'm a bit confused.

    • @ArnoldRowntreeTeachesFusion360
      @ArnoldRowntreeTeachesFusion360  4 года назад +1

      I know that 'Ground' works OLLE, come to think of it, I can't remember who it was who said to use a rigid joint with the top level. It was someone at Autodesk in a live stream and I don't remember a reason why other than that he said this is the way they designed it to work.
      I'm sure a lot of others who use ground are re-living Solidworks days but on educational level projects like the one in this tutorial you can really get away with almost anything. Thanks for the question though, I'll see what I can find out.

    Right at 6:05 you say, "Make sure this circle is Concentric with the shaft of the indexing wheel." But you have the coincident tool selected. When I try this, it makes my Base too small. Here is what it's doing: ruclips.net/video/9J72PIlIRXA/видео.html

      @ArnoldRowntreeTeachesFusion360  3 года назад +1

      Yes P3D, I see that and well done so far! Thanks for your video, that makes it so easy to understand your question. I think you'll find that if you put a dimension on the radius of the curve or a dimension on the width of the base it won't behave like that. You'll be all over this in no time but please come back if you're still stuck.
