Pin-Locator
and RTP_Base relationship:
The offset or step on the Pin-Locator pins helps to
determine how much trimming of the impression will be necessary before
the RTP_Base replaces the Pin-Locator on the Pouring Jig. Once the
RTP_Base is attached to the Pouring Jig after the alignment process is
complete, the RTP_Base is lowered into position. The yellow Swing-Arm
Stops must contact the green Pouring Jig Stand when the RTP_Base is
lowered into position without any interference from the impression. If
the RTP_Base contacts the impression before the stops make contact, then
you must trim more of the impression or lower the Pouring Jig Swivel
Table. Lower the Swivel Table if you must, but remember that your stone
die will end up longer.
Caution:
Getting the
upper and lower Pin-Locators and RTP_Bases mixed up
is the mistake most frequently made when learning this system. If the impression is an
Upper, then you will use
the correct size Upper Pin_Locator to line up the impression on
the Pouring Jig. Since the impression and the Pin-Locator is an Upper,
you will need to use an Upper RTP_Base. How you minimize
this problem is explained on the following page.
