Looks pretty good from Here. If you are like me you are your own worst critic! Take it easy on yourself!!! On large thin sections like that a friend of mine would use "caplets" (Spelin) They are thin aluminum spacers that are placed inside the mold cavity when you reassemble the cope and drag before you pore. They help hold the cavity apart and they partially melt because they are so thin. Just an idea:o) Thanks for sharing, Wes |

Hi Stew Davo and Wes, I guess Ive been on this project for a long time and I have remade several bits due to being my own worste critic... This thing is due ot be painted so I can live with it.... but thanks for the encouragement... :beer: Wes, Im certain there are ways... and even though Ive been doing this a long time I am inexperienced (in commercial terms) so Im going to research caplets..... maybe I can get a better result... ow shut up Artie and get on with it.... :doh: :bang: :zap: More soon.. Cheers Rob |

That looks pretty darn good to me Artie/Rob. Nearly big enough to be a griddle. You know, between you two Robs, a guy can learn a lot just from visiting this one forum. A question from a fellow who doesn't know casting; When you pour something long and flat like this base piece, is it more likely to cool too fast on one end before the molten metal gets a chance to flow into the whole cavity of the mold? Thanks again for your pics and efforts here! |
