My first attempt at casting involved melting some lead to make window weights. I'd just acquired a Sievert torch and decided the biggest head should be about right. I put all my lead into an old aluminium saucepan, sat it on an old metal chair and pulled the trigger - admired the "WOOSH - ROAR" and huge flame that it spat out. I was extremely gratified when moments later the lead just dropped into the saucepan, but less so a second or two after when the pan followed it. If anyone has a use for a block of leadaminium alloy just let me know.. |

In my workshop days we had a steel mold that we would stick a round bar bar of stainless steel into, and fill the mold with molten lead to make soft hammers. I added some aluminium to mine. They lasted longer, were better balanced for hitting things and still soft enough to do the job. |

leadaminium alloy :lol: Hey! I know where there is a nice batch of stainlesssilverbrazingrodbronze alloy is at now that you mention it. When brazing liquid argon lines goes BAD! |

I will be happy to assist you with your learning process if you need help. Dan --- End quote --- thank you for your offer it is mainly aluminium / alloys im thinking of using in the front steering assemblys as it shouldnt be under too much stress as the finished car wont go faster than 4mph you are a bit far away but i would like to ask a few questions how easy is it to get a propane burner to reach high enough temperatures to melt aluminium alloys is your furnace home made, if so it it easy to build does the furnace make a lot of noise (my neighbours have a baby!!) many thanks malcs --- End quote --- Hi again Malcs, Propane burners will easily melt aluminum. I use waste motor oil myself but it requires a blower which can be noisy. The naturally aspirated propane blowers are reasonably quiet so you probably could melt without waking the neighbors baby. Here's a link to a great casting site that should have enough information to get you going. http://www.backyardmetalcasting.com/ Everything from burner and furnace design to making flasks for pouring.
