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
