Many Thanks lads for all your comments and interest in this post :bow: :bow: :bow: :bow: :nrocks: I hope that sharing the tail so far (more to come) may help inspire others to have ago at setting up there own foundry and casting up some parts. Thanks Don , :beer:, I am pleased with the way the Ridder Ericson engine casting came out , it took a few goes to get there , I could take some better photos of the engine and patterns , if anyone wants a look ,,,,,,, OH yes BIGGER castings :) Thanks David D and Joe ,,,,,,,,,,I still have to try out the chimney , hopefully over this up coming long weekend . :dremel: Hi Rob T ,,,,,,,,, No,,,,,,,, hats off to you :bow: , you are melting and casting Brass which is allot harder to get right , than the Bronze i cast the above parts from . I would say Brass is the hardest of the metals the amateur is likely to cast and get right For those that don't no , Rob .T , mentioned good temp control when casting Brass , this is because if you over heat Brass , the Zinc starts to boil off , and also when you over heat Brass you tend to end up with allot of dissolved gas in the molten metal , leading to poor quality castings full of porosity , I have not been so successful with Brass , so i melt Bronze instead , it dose melt at a higher temp , but its allot more forgiving .I will be trying my hand at brass again . Cheers Eric and Dean ,,,,,,,,,If anyone is ever in the NE England please feel to call in for a brew and a chat :thumbup: Rob (Slowcoach) Go for it , tizz great fun :thumbup: If your scarp is not swarf you may as well cast it up ,,,,,,if anyone is going to use swarf , first it needs a wash and THOUROLY DRIED, then you have to start with a good half full pot of molten metal , because if you just fill the pot with swarf and heat it up you end up with nothing , due to the very large surface area and the swarf being thin in section , it just oxidises away to nothing , so you fill up brown paper bags with swarf , scrunched up tight , then you plunge the parcel into the molten metal ,holding it under the surface , allot of faff for a little metal . Thanks Rob W :D |
