We have no access really. the above pics are of a dragon orb 3 heatsink which im modifying, and next to that the ocpc atlantis nb block which I will be changing slightly with a dremel
Currently doing some research into *if* it would be economical to cast copper and silver into the shapes I want. If any one has any input to this idea its welcome by anyone thats tryed it, but I'd prefer peopple that have only researched it/read other threads not to argue the downsides of it, as that wouldnt be usefull to me....
Attached pic shows how I think i could get around most problems associated with casting (pic attached), for example, there would be no oxygen problems. After its cast the gas is removed, and the steel is hit from behind to knock the silver mould out. The main cost of doing anyhting like this would be the steel, gas, and fuel.
The gas would be pumped in before the steel is heated. Im not sure which type of gas would be best for this either...
