John,
When you get chance, I'd like to see the pictures of the Bristol 22 that you mention. I've never heard of tabbing on a hull-liner slot. Would be interested to see how that worked for you.
Regards,
Roscoe
P.S. Scott, glad to say that I cannot feel your pain. I'm not sure if it's ever been 10 degrees here. Was a cool 70 today. We pay our dues, though, in an oppressive and miserable way the summer.
