Make is 1913 5'8" Knabe. The bed is not made of laminate but there are some 
joints that needed some epoxy when I was filling in the splits early in the 
project and had it upside down. Was mainly the support beams and rim and the 
outer edge if the keybed.
Before I did any work on the action the keys were chucking. Solved the 
problem when I replaced the balance key pins with .162 (original was .146)
Had to ease quite a bit to get them to fit correct and today found that I 
had overdone it on several - only very slightly. I have resized the holes 
and re-eased and found that it helped but was not the cure I was looking 
for.
