Hi To All, I havn't been contributing very much on the list as it is on my home computer,and i only go on ti every couple of days. I see that there seems to be quite a lot of interest in to boat boilers which i am interested in also casting/smelting another thing i would like to get into again both alumiumn and cast iron. I contacted the boat links that wilfried gave me the web site address for and it gives me building advice for engines, boilers and hull designs. I glad that the numbers of Alan's list are growing and that most people are pro active, i must get the Emails forwarded to work so i can contribute. yours John Burridge > Message date : Oct 21 2004, 01:03 AM > From : "Ronald" > To : modeleng@xxxxxxxxxxxxx > Copy to : > Subject : [modeleng] Re: Melting Down - Smelting > I have found the if you are just smelting aluminium you can build a muffle > of normal clay bricks and just pack the gaps with mud .Use an old iron > saucepan as a crucible. > ----- Original Message ----- > From: "Bob Logan" > To: > Sent: Monday, October 18, 2004 9:13 PM > Subject: [modeleng] Re: Melting Down - Smelting > > > How far are you from a coal mine? the overburden above the coal seam, is > usually a good fire clay. > > Bob L. > > ----- Original Message ----- > From: "Terry Lane" > To: > Sent: Monday, October 18, 2004 10:11 PM > Subject: [modeleng] Re: Melting Down - Smelting > > > > No Al, not much clay around here at all.
