A.C. Gilbert

GilbertBldgNew Haven Connecticut, Electric Kaster Kit/Electric Slush Mould Kaster Kit 1931-1942

Gilbert sold “Kaster” sets from 1931-1942. Like all the other mould manufacturers the war brought using lead to a halt. A.C. Gilbert however had other product lines and was able to survive during the war eithout having to depend on their Kaster sets. There were 44 molds produced by the A. C. Gilbert Company. 29 semi flats and 15 slush molds. The first listing of moulds is for pouring solid models while the second listing is for pouring slush or "hollow" models. 

There is a video by bob Zimmerman on how to pour the slush mold. Also old catalogs. Also history of AC Gilbert that can be found at the The AC Gilbert Society: https://www.acghs.org/

Solid Model Moulds
These model moulds were square with the back of one half of the mould having a round hollow piece centered while the other half had a Z like piece centered on it. This was to instert into the mould holder so that the mould could be held in place by the A.C. Gilbert Machine.

Slush Model Moulds
The following moulds were for the A.C. Gilbert slush mould maker and were round rather than square like the above moulds. Note that there are two different types of slush moulds:

  • A shank with opposite inside flats called a flatted shank.
  • A shank that is round inside.

So far I have seen the non-flatted shank in the earlier moulds at least until S45, with the flatted shank appearing at least in S51. Both round types have cut outs or notches on the edge of the mould and holes in the shaft for the retaining pin. This was to instert into the mould holder so that the mould could be rotated to create the "slush" or hollow portion of the model. If you have any models between these two let me know in the comments below which type of shaft you have and I will update this info!

There is also an extremely cool video of how to use the slush mold maker over on YouTube
