Mould modification

[Steveu]

All,

Has anyone else have a mould that has a dog-point screw like this? It also has a small brass plug to put tension on the sprue plate pivot screw. The mould looks like it has been modified for a casting machine. I called Magma and they said it did not sound like their modification. I would like to do this to my other moulds.

Cheers,
Steve
