    Yes, 'lost wax casting' would be my guess as well! This is very interesting, can't wait to see how it turns out!

    Interesting thing, looks like good sized.
     
  6. Make a fine deduction to structure and then a gypsum form around other casts to pour around from it candles!

    hY all :)

    we talk about gypsum, plaster, cast? I made the mistake to cast lead when the gypsum was not dry enough, the water exhausted to steam and it was destroyed by a crack and little explosion. The liquid metal ran out, but didn´t hit me (good luck).

    I think professionals use special sand instead of plaster but don´t know about exactly. Youtube has videos in making aluminium slingshots.
     
  8. Gypsum form for wax candles!!! @G_Y

    I've never cast anything more complicated than lead ammo.

    My only advice is that before the fire is lit do a dry run. Go through all the motions of the job, just like you would, only without deadly molten metal. Do this with a "worst case scenario" mindset and have equipment ahead of time in that event.

    Your form looks great, hope it comes out good!

    I'm sort of leery of the lost wax process. I was melting some lead for a project and my brother threw a crayon in it. At the temper lead melts, wax explodes. Double up on your safety precautions.

    i'm thinking about try to make an aluminum slingshot with this process. What source of aluminum can be used?

    We have had success with chunks of old transmission casing from an old Chevy. (This was just a simple billet in a steel food can to make a miniature piston out of).
    Its fun to bust up with the sledge hammer too:D

    I think almost anything will do, ask your car nut friends to save you dead water pumps, etc. of cast aluminum.

    Places that buy scrap metal can always sell you some too.

    Edit: Actually, the stuff in your scrap pile is probably fancy aircraft alloys and stuff--maybe even better:cool:

    yes, the professionals use "green sand" it is sand mixed with a few other chemicals.

    Thanks for the advice on all of the safety precautions, i will be sure to do a dry run along with other safety tests.

    Please, don't try to pour the molten alloy on the wax model. This isn't the way it works.
    Go to YouTube and search for "Fertigungstechnik Gießen". In that video every common casting process is described.

    With the materials you have available, you may be better off trying a 'lost foam casting' out og Styrofoam. I have seen good (and safe) results from that technique. I am glad you were not hurt!

    I have lots of external fixator scrap from aluminum. Maybe I'll try to melt those. I was afraid to try, thinking it was an specific type of aluminum to melt.
    Thanks!
