Stalagmite                            Pouring Open_Bases

Arch Open_Base:
                            
Stone is teased around all pins and index grooves are filled with stone. Vibrating the model a little will help settle the stone around the pins and help eliminate bubbles. After making sure a Mounting_Plate is attached to the Open_Base, fill it with stone and slightly vibrate.
   
      
The pin side of the model is lowered into the Open_Base (make sure the vertical web behind the snap falls between the two centrals). Tapping on the side of the base will help settle the stone. Remove excess stone and allow to set. The bottom of the die area should be even with the top of the Open_Base. After the stone sets, excess stone can be easily removed from the plastic base with a wet sponge without getting the die model wet.

Since die pins are available on the market in variable lengths, the pinned model should be placed inside the base and checked before pouring. Also, the vertical web behind the snap should end up between the two centrals. The vertical web behind the snap may need a little trimming near the top to allow the die pins to slide down on each side (usually only a problem on the lowers because the teeth are so small and close together).
