I've had this unit in a box for a few years and decided to set it up - but for the life of me I can't figure out how to set up the powder measure trip rod. Anyone have a decent pic? I might be missing a part or 2....
 
There isn't a trip rod. The measure is activated by the funnel in the powder die. You need to adjust this so the measure moves fully from stop to stop, without over belling your brass, as it also acts as the mouth expander.

The rod system is a fail safe, pulling the measure back under the hopper for another charge. You should adjust it so that at reat, there is just a bit of spring tension.
 
Just make sure the rod that pulls the bar back and forth is tight. IF it works loose the bar won't be activated and you will be reloading empty rounds. Don't ask how I know this!
