Hi Lads Thanks Eric , :thumbup: your more than welcome Hi Dean ,, I will post up all the steps in the moulding and casting process , plenty photos ,few words :lol: this build could turn into a long post . Tonight work , the pattern is just about finished , it still needs the lettering done , filleting,and a coat of paint , about a good nights work still left in it. I must put an M&M in the shot for scale :lol: :lol: :lol: :lol: . Then i had a brain fart ,,,,,,,, will the core fit in the oven :bang: :bang: :bang: :bang: :bang: nope ,,,,,,,,, :bang: ,,,,,,,,,, looks like plan B ,,,,,,,, i will have to get some sodium silicate to use as a core binder . Cheers Rob |

And so the story continues.... sodium silicate? Is that the co2 activated liquid? The oven misfit reminds me of a guy in Sydney many years ago... made the evening news..... spent a decade building a yacht in his back yard, by the time he went to remove it the neighbourhood had been all built up including hi tension power lines outside his block..... cranes cant get it out....still sits in his back yard... made it into a granny flat...... :( More pics? Looking great bloke! Rob T |

Rob another way would be to stack 4 casting boxes one on top of the other, the middle two would have to be exact height of the pattern you could then pull each pattern from the mould and save making a core. Though it may not pour so easily on its side Looks good though. |

Hi Lads Cheers Rob .T ,,,,,,,,, :lol: :lol: :lol: :lol: I have the same problem now i have extended my workshop ,,,,,,,, :bang: IF big IF i finish my 4" Tasker Tractor i cant get it out the garden :lol: :lol: :lol: Yep thats the stuff goes of with CO2 . :thumbup: Hi Jason ,,,,,,,, I had thought of using CHEEKS ,,,,,,,,,, boxes that go between the cope and drag , but opted for coring ,,,, I may get away with a green sand core ,as they are fairly large ,, The only way to pore this is on its side , fingers crossed Cheers Rob |

Hi Rob, that's looking like a fine set of patterns and cores, I'm really looking forward to the shots of the ramming of the patterns and the horizontal pour. I hope you have the camera and practice to do a video of the pouring, that'd be nice to see, you've obviously made a pattern or two before, and I'm still working out how you're going to use what you have to ram up a mold. That idea of cheek boxes didn't sound bad, and it was something I could see in my mind. Great work and nice pictures, looking forward, :thumbup: mad jack |
