I had my first go at casting tonight. I thought I'd be able to make a blank with 3 colours but it goes off all of a sudden and the red was a lump as I poured it and so it was impossible to mix the colours together and so also a few small pinholes. I put it in the pressure pot but think the damage was done before I put any air in at all. A disappointment was that I used pearlex for the colouring but there is no shimmy at all. Roll on MkII tomorrow.
