The Opposing Index-Plate is used to lock the Opposing_Base (quadrant or arch) into position when using the Pouring Jig to pour Triple Tray impressions.
Do
not confuse this procedure with the Articulated Triple Tray System. The
Articulated Triple Tray System is a stand-alone design and does
not need the Pouring Jig, refer to the Home Page
under section entitled "Using the
System," and go to"Pouring Triple Tray Impressions (using
the Articulated Triple Tray System)."
The PJ_Pin-Locator Swing-Arm Stand Extension is used to compensate
for the added thickness of an Opposing_Base when pouring a Triple Tray
impression using the Pouring Jig. Refer to the Home Page under
section entitled "Using the System," and go to "Pouring Triple Tray Impressions (using
the Pouring Jig)."
