Help on hammerless

[BIGHAMMER]

I recently took apart my hammerless and polished some parts. I have reassembled it and it would work fine for like two pulls.
Then the trigger will pull but the founder will not rotate.
Taking the side plate I see that the bar that advances the cylinder falls sways from the cylinder.

I notice there is I spring leg in the trigger that may I may not be holding the bar "forward" does this make any sense lol?

Thanks for any help in advance.

With all due respect, before you open up a revolver again, I strongly recommend getting Kuhnhausen's book:

Heritage Gun Books - S&W Revolver Repair and Maintenance Manual

You will learn the names of the parts inside so that we can understand your question(s). You'll also learn how the action works and how all of the parts interact. Finally, you'll learn how to put it back together correctly.
