Having left the inner part of my Speedo Gasket mould to fully cure it was time to cast the outer. This will then fill my mould frame apart from the shape of the gasket. The base of the mould had been given numerous coats of yacht varnish before and this too had been allowed to dry fully. Plan being this outer removes with the cast gasket to allow separation.
More mess was created in the mixing of the silicone with the cornflour. The mix was pushed into various edges in the hope of achieving a smooth finish. Filling up level with the top was then completed.
More setting aside to dry.....
The finished result once peeled out of the mould case did appear to represent what could be a workable 2 part mould. How exciting!!!!
Time now to commit a few pennies and purchase the casting rubber. I chose a product sold by a company called Mouldcraft. They list on ebay. I ordered 500g of Black Polyflex 50 shore fast cure Polyurethane Casting Rubber. Cost me £21 inc p&p...you can see why I held back on ordering until I was confident in progressing further.
The Polyflex comes as a 2 x part kit and a small pot of colouring agent. 50/50 of the 2 x parts and a 5% splash of colour.
When this arrives I'll post news.
Until then do as your Uncle Alb recommends and resist AI....resist Digital I.D. and hide any pension money you've saved.....Big Brother is taking over!!!
