What is the traditional way to pull this off? Do I need a pour spout on each side or will one suffice? Will the index finger and thumb hold with super 77 or do I need pegs? Thanks.
One pour spout at the top should be fine, as long as you have bleeders at the top to allow that last air pocket to fill up.
You can use magnets or even super glue (sparingly) to hold the thumb and index finger portion of your core together during the pour. I would just keep glue to a minimum as you'll need to break the two pieces apart for demolding.
Hot glue is also an option, as you can heat up the mold to help the glue release.
