[pianotech] green piano with bass bridge problem

[Terry Farrell]

Just curious Ron, did you use West System epoxy? Did you use fillers?  
If so, what kind? How did you measure your 5:1 mixing ratio? I don't  
like the pumps at all for measuring. I always use a good scale. And in  
the case of mixing up smaller batches, it becomes more and more  
mandatory to measure with a good scale. Temperature can also be an  
issue - was it cold?
