I'm building a couple of Isettas as Christmas presents, where the Isetta is a small but kick butt bluetooth speaker designed by Paul Carmody https://sites.google.com/site/undefinition/isetta. If you look at Paul's original design, and then the finished speaker https://f48a8583-a-62cb3a1a-s-sites....ta/Isetta1.jpg, the screws holding the front on aren't over any part of the cabinet design, they're just kind of out there in empty space, which tells me he probably added braces in the cabinet and screwed the front to those. But I'm kind of far along here so while I can fit some braces, there's no easy way to make them stick other than glue or epoxy, which is what I'm leaning towards, and then I thought I'd add some threaded inserts and use some nice looking black hex cap metric bolts I have. I have limited experience building anything like this, though, so I thought I'd ask here. How would you stick it on there?
Here's a pic with the braces cut, but not fastened in. They're a tight fit! https://i.imgur.com/8BEuaBm.jpg
More pics from the build here. As you can tell, I am trying to make them look nice! https://imgur.com/a/nlgW5E0 Let me know your thoughts on how to get it done, thanks!
