Last time I cleaned my first gen RCBS bottom pour I realized the spout is conical but the rod that stops the alloy flow is just a regular bar with a flat base. I was wondering if anyone machined that rod to be also conical and close the spout better.
One of my first gen RCBS is very old and it won't close that good anymore. It drips especially when the temperature is on the high side.
Just looking to see if others have done such thing or I'm thinking to far.
