Thanks again for sharing your advice, and information.   I,m not at my shop when these simple molds are cast.   I'm thinking that the plaster can be filed with a rotary file back home for making the sprue, the vents might be just on one side of the mold.  All of the lead I've ever casted had no vents.   Now I,m learning.  Maybe others are learning too?  Thanks for sharing.   Lets all have a happy holiday.   More soon. ;)

Thanks to your suggestions and a new year some more practice plaster o Paris molds seem to be a bit cleaner and easier to build.  These are about 20 oz. and are poured without the clay as when I started.

 Removing the pattern is somewhat easier now.  I,m hoping with the wire eyes and hook loop in the lead as well as the sprue to pry and lift with it will be easier for removing the jig.
   I,ll pour some and take you some pictures.    Thanks again for your help. ;)
