[Public-List] Epoxy failure [was Steam bending Teak]

[Rachel]

Bob,

Thanks for the links.  I was offline due to the storm this weekend, so  
I'm just looking at them now.  Reading the first one, it seems they  
are not blaming all epoxy, but that the tunnel constructors used fast- 
set epoxy rather than "normal" set epoxy.  Apparently fast set is more  
prone to creep.  I've always used the regular stuff, myself.

Have you heard of any instances of failure due to creep of epoxy in  
sailboat construction or repair?  I have heard people talk about the  
possibility for such, but have not read of an actual failure (of  
course I'm not counting cases where the epoxy didn't set up due to  
improper mixing, or where there was some other mistake made).  I'm all  
ears though, since I do use epoxy.

Wouldn't cold-molded construction be a prime candidate for failure?

Thanks again,

Rachel
