--- Quote from: AdeV on February 18, 2010, 04:44:12 AM ---....I did wonder about pouring in sections/layers, but I'm not sure what stresses that will set up in the wax. I'd hate to get half way through machining and the whole lot goes "pop" & breaks up... --- End quote --- If you do need to re-inforce it, instead of using discrete candle wicks, how about using something like Rab C. Nesbitt's string vests? would need a test first though - they may pull-out rather than cut when you come to machine them ... |

I'm going with Plan B instead.... :proj: I've just bought 2mtrs of nichrome wire, which I'll mount up on a wooden dowel framework; attach to a car battery, and I've got myself a nice big flat heater, capable of ~200 degrees C (a shade less, actually) - perfect for keeping the wax molten in the mould until I've added enough. Once the mould is full, I can just pull the heater out, and let the wax cool & set naturally. Photos will be forthcoming when the wire arrives... |

If you have a charger, it might be worth using it instead, or (if it won't cope with the load) use both by putting some charge back into the battery while you are discharging it. Andy. |

Unfortunately, that equates to just 25 watts.... I'm not sure if that'll be enough to keep the wax liquid while I frantically melt & add fresh wax... Only time will tell... |

Might be ok - yo just need to delay one layer setting until the next is poured. |
