I don't think it has any purpose other than thickness gauging. With a caliper, you'd have to stop frequently to check. With the plugs, you simply keep working, hollowing the inner surface until they appear. The more plugs there are, the more regular/consistent will be the thickness.Bob Holtzmanhttps://www.blogger.com/profile/05878339327766256094noreply@blogger.comtag:blogger.com,1999:blog-6466695305125791022.post-49298212564729458812011-12-01T01:56:37.905-08:002011-12-01T01:56:37.905-08:00Good film thanks.

Or. do the plugs have some additional purpose such as stopping cracks developing during expansion?Edwinhttp://dark-age-boats.co.uknoreply@blogger.com
