The linings are 1/8" thick. If you are going to arc them in, you may want to go with a little bit thicker material.
As for asbestos, my father worked in a boiler factory after the war. He said it was pretty much snowing asbestos all the time on the shop floor. He made it to 91 years old with no problems.
Very sorry to hear that Ian. No one should out live their kids. It seems that Asbestos is one of those things which has no effect on some people, but it can kill from just one grain.
At age 11 I helped my dad lag our 12' steam boiler with chicken wire and Asbestos Meal. Mixing it up with my hands with water in an old tin bath and smearing it all over the boiler. I thought it was great fun at the time:white_frowning_face: Ron
Yes it is strange stuff. As you said it effects some people and not others. I look back to the 60s and blowing out brake drums for years, it doesn't bear thinking about.
