I posted this under the Paper Patch thread, But felt it would make a Good Thread of it’s own. This is one of the More important Steps in my Casting to Achieve OPTIMUM Fillout, Something i learned through Trial & Error. If there is enough interest in Seeing exactly how i do this, I will set up my Little Video Camera and Run a Short Youtube Video Showing the process
Compression Casting is when you Fill the Mold, And you continue to Hold the mold under the Stream of Lead, even Though the Mold is Full, The Weight of the Lead is “Pushing Down” in the Cavity, it’s called Compession Casting. Certain Molds React Very well to it, and some Not so much
Notice the Shape Of the Pour Spout? Be it Ladle, or Bottom Pour Pot, They have a Slight Taper, Now look at the Hole in a Sprue Plate, it is “Dished“ Shaped, These 2 Fit eachother perfectly. You want to “Marry“ the Spout up with the Sprue Plate, Then Fill the Mold, Holding them together for a Few Seconds after the Mold has Filled.
PRACTICE, PRACTICE, PRACTICE, And Be Consistent
You will learn exactly how long it Takes to fill your Mold. Lets Say it Takes 2 Seconds to Fill, Hold Compression for 3 Seconds, So it takes 5 Full Seconds per Cast Bullet (That is a Just a Close example, You need to Tinker around here til you find what works Best for your Mold)
Compression Casting is where you will get OPTIMUM Mold Fillout
