I recon you done great being 1st time pete .I used my small furnace the other day to heat some 2inch x 3inch up so I could shape it .I thought id take ages but it only took about 15mns and it was orange hot and the kao wool inside didn't even change colour .
today im going to have a go at my first pour of alloy .ive made some flasks and have about 140 odd Harley pistons which I ground the carbon off an then degreased them an put them in my powdercoat oven to dry out .I made a crucible from a 1kilo gas bottle and welded a spout on it .im gunna use a mix of playsand from bunnings 6 dollar per bag an bentonite clay dust with water for the mould .
1st pour will just be a bit of round bar 2inch by 9 inch long then if all good after cooling an running a few cuts on lathe I will attempt to make some rocker covers for a Harley motor im building .Harley cases some barrels I made yrs ago at a mates factory I want too make the heads and run an over head cam on each head just something to do rocker boxes will be based of a mix of twincam and evo so gaskets can be easy to buy ect .if my first pour turns out like yours pete ill be happy as .
when my dad was alive he was here with me an my sons an he said if the pour comes out in one piece to start your on ya way he also said they used potatoe as the degasser .have anyone heard of that before
cheers ron
