I was having a problem getting decent boolits from a premier brand mold. I thought it to be appropriate to make sure the mold was the culprit as my Pro Melt had been dripping lately (yes, Pro Melts drip too). I've cleaned it before & really hate the job. Every time I tackle this job, I start out thinking one way & fortunately I discover that my thinking was wrong before drilling out some metal I can't replace.
Check out the photos. 1st impression (to me) always assumes that the "A" surface is the valve surface that needs lapping. It looks made to order to line up with the large opening in the photo (inside view). They even have the same angle. Furthermore: the distance from "A" to "B" is exactly the same distance as "C".
Measurements prove otherwise:
1. The diameter of the discharge hole is .106
2. The diameter of the small end of the valve is .150
3. In order for the large sealing surface on the valve to match up with the large seating surface, the valve rod would need to be longer.
I'll lap the "B" end of the valve rod with the small step type seat just below the large opening.
If I'm wrong, please correct me. I'm getting accustomed to being corrected.
Henry
