I don't receive Guitarmaker. What's the article about?

I was surprised on the results . It was a glue hardness study. Very interesting article. ASIA is back on track and we are hoping for better things in the future. If you were a member , please think about rejoining. It is a terrific organization.

Although the hardness of the glue is probably one variable that makes a difference, I don't think it's the most important one, nor am I convinced that 'harder is better'.

I wonder about the fact that his testing showed HHG as softer than Titebond original: he does note that the HHG had a tendancy to crack in bulk due to shrinkage, and that could easily have lowered it's 'hardness' score.

As many people do, he seems to associate hardness with low damping. This is not always true.

In using the dictionary definition of 'dampening' he gets away from a more physically rigorous and useful one, where 'damping' is related to the rate of energy dissipation in the material. I do think that the damping factor of glue is probably important, and I think we need to do some tests to look at that.

As always, I'm happy to see people experimenting, even when I don't agree with their methods or results. The important thing is to open things up for debate: it's really the only way we'll ever get it right.
