Connecting Rod proper travel.
I have watched lots of vids but still cant get my conrod's small end to travel up and down in straight line as the crankshaft rotates. They flap side to side. HELP and thanks

If you attach your cylinder heads then you can use a axis constraint.

Referencing your comment; the large end of each connecting rod has to travel side-to-side, and the small end has to be mated to something to drive it up-and-down. If you don't want to see the cylinder head, then Hide it after adding the mate.
Or maybe use a different type of mechanism. A Scottish Yoke provides a pure up-and-down motion of the rod with zero side-to-side motion. (sorry the animation below is rotated)
I know your trying to help, but i make a axis, reference line and a head but i cant not use those 5 options in axis menu to line the conrod little end to travel up and down. sorry. must be missing some lil option somewhere. driving me nuts.
You'll have to add a "parallel mate" between one of the connecting rod's planes (a vertical plane) and the crankshaft's corresponding plane.
But it has to be a parallel mate.
All sorted thanks. Thanks for everyones help. Used the pistons connected concentrically via a vertical line and the piston skirt. Sorry about the extra stuff on the front of clip... https://www.youtube.com/watch?v=07lmCFGz7ic
