I've never used any glue with this system. I've built 11 acoustics and resonators using this setup and haven't had the slightest problem with any of them. However, as I said above, I generally place the mount directly under the 19th dot inlay but in this case because of the location of the upper bout brace, I wasn't able to extend the support that far. So I had to place the mount under the 17th instead. In the future, I may eliminate the upper bout brace on this model. The solid fretboard support under the soundboard should adequately support the top without the need of that brace and it would allow me to place the mount closer to the end of the fretboard.
