    Home alloy sand casting

    Hi Lionel, I'm a mature apprentice moulder and have just finished my block release at TAFE. I've been in a foundry for about 15 years now. You can do cast iron at home with a small crucible and a home made blast furnace running on lpg with a high air flow, problem is it will take quite a while to melt (average temp to pour cast iron is around 950 - 1100 degrees). Another option is to 3d print the part to use as a pattern and approach a foundry in your area. The only TAFE left in Australia still doing a moulding and casting course is Skills Tech at Acacia Ridge here in Brisbane. Mike McCabe is the teacher and also runs hobby courses for people interested in doing moulding and casting at home.

    Another option for you is to get it welded. I've welded a lot of cast iron over the years.

    There are also many different mediums you can use to make your moulds out of too. The best one for use at home is called green sand. It's non poisonous and is reusable, I get amazing clean results doing aluminum, brass and cast iron in it.

    If you want a hand etc I can put you in touch with Mike another group worth asking are those into hobby railway steam engines like 1/5 scale live steam stuff. They would definitely know who could help you with casting etc.

    Cheers for now

    Join "metalworkforum.com" they started Foundry and Blacksmithing sections about a year ago + a General section for all your lathe questions. It's also Australian based.

    I built a casting furnace based on a book purchased online: 'The Artful Bodger's Iron Casting Waste Oil Furnace', also built a moulding bench with a bathtub full of greensand under a hinged benchtop, unfortunately I just have not had the time to do much casting at all and have not even made an attempt at cast iron yet. All sorts of projects on the list but no time to attack them.

    Hello All,

    Thanks for the link to furnace POD - and for the link to the Australian site Crash...

    Here in Bundaberg we are in the middle of a series of storms that have extended over this weekend. So I have not done much outside today. This has given me time to chase up some YouTube clips about oil fed furnaces. I found a couple of sites that are interesting.

    This is the first in a series of 7 parts... Make a Waste Oil Fired Furnace
    Metal Casting at Home Part 49 Oil Fired Furnace Build Part 1 Wheeled Base

    YouTube


    Here is a different type
    YouTube

    I did find an Australian version by Luckygen1001 which also shows a crucible pour trolley that looks safer to operate than hauling hot metal around by hand. YouTube

    Luckygen also has a clip where the dimensions of the furnace are run through... YouTube

    Plus there is one of the furnace being overhauled YouTube

    Kind regards
    Lionel

    Called on a company earlier today that cast magnesium alloy, possibly the only company in Australia doing this.
    I turned up just as they were doing a pour.

    Mainly race parts for bikes & cars. They had a Repco Brabam block & pistons that they'd cast.

    Interesting stuff, spent far too long chatting to the owner (better than working).
