I got tired of hanging onto my old RCBS aluminum powder trickle with both hands to keep it from rocking back and forth, and sliding around on the top of my bench while I turned the knob.
Random Google image of someone using both hands to hold one below.
So I filled the bottom of my RCBS powder trickle up with molten lead alloy,
(I removed the plastic pieces first of course) giving it some much needed ballast.
I'm pretty sure that I am not the first person to have done this modification.
In addition to the lead, I also added a small square piece of old mouse pad to serve as a non skid bottom. Adding the lead ballast to my older RCBS powder trickle made it a lot more user friendly.
With both the lead weight on the bottom and the non skid base, the trickle hardly moves at all while it's being used. It can easily be operated single handed now without sliding around, and is much less likely to get knocked over by accident.
I also found a black silicone wine carafe lid, that fits the opening on top. It makes a nice dust cover for the powder trickle when it's not in use.
