Hi @ianpmitchell
I don't know if you have a solution for this already because this discussion seems to have gone a bit cold but I managed to work out how to do this. Maybe you have too and if so I would love to know how you approached it.
Can I first say that I deleted all the joints in the model, aligned the components and then added new joints which took me quite a while so I have not included that part in the screencast but I will if you need more information.
The thing is, doing the above was not necessarily necessary if you know what I mean but I just like to align components and use rigid groups because it makes for less cluttered joints and joint structure and avoids joint conflicts. I think that you should be able to achieve the same thing with your version but let me know if you have problems.
So basically if you look at the video you will see that at around 0.30 in the screencast, I drew a sketch just to get some dimensions. I used the sketch to work out that 10 degrees of rotation of the component Fork 1 would amount to approximately 7.195 mm of movement in the cylinder joint on the component Bottom Pivot 1. I then used this calculation to setup a motion link between the two. You will see this at around 1.34 in the screencast.
I also worked out in the sketch that the component Slipper 1 would rotate roughly 12 degrees in order to remain perpendicular to Bottom Pivot 1 and included that information in another Motion Link between those two components. This can be seen at around 1.58 in the screencast.
I didn't work out either of these things accurately because it is 3AM here and I ran out of time really.
I found that any type of joint I tried to place between these two components locked the rotation of the bevel gears etc. Which it quite rightly should in a complex joint that rotates and slides on a rotating body like the one you have there. Maybe in the future there will be a joint native to Fusion that does this but in the meantime I think this is the only solution. Hopefully someone more experienced will have some information on that.
Great model by the way.
