Why is My Slot Cam Mechanism Not Working

Hello,

 

I have created a slot and pin type cam follower mechanism, depicted in the image 1. There are 3 components in the assembly:

  1. A ground plane
  2. A bolt carrier
  3. A bolt inside the bolt carrier

I have created a slider as-built joint between the bolt-carrier and the ground plane and a cylindrical as-built joint between the bolt-carrier and the bolt. I have enabled contact sets and added the 3 components to the set.

 

On the side of the bolt there is a pin (part of the bolt) and on the same side of the bolt-carrier there is an angled slot.

 

Now according to my expectations, when I move the bolt-carrier forward, after hitting the ground-plane's perpendicular extrusion, the bolt should rotate clockwise because the the pin following the slotted-cam. But that is NOT happening. Moving the bolt-carrier backwards the bolt-carrier and bolt move back as expected but only when I move them forward and hit the upward extruded ground plane, the bolts stop.

 

Why is the bolt not rotating as per the slotted-cam and pin mechanism is my question.

 

File attached.

Sir after watching the video and @jhackney1972's method (by going through the design history in the attached file) I have found both the procedures to be little bit similar in that they both have the "sweep along a path" cut to make the slot. This has worked out for me and I'm marking this as the answer so that others can know both the methods.
