Default for a wood chassis, is glue enough?

Building a DAC chassis out of 3/4" solid mahogany used for base and 4 sides. Top wil be 3/16" perforated aluminum. Dimensions are 12"x16"x5". Sides will be connected together using mitered edges. Aluminum top will be screwed down into top of sides.

Do I need anything other than glue (wood screws, etc.) to glue the 4 sides together, or the sides to the mahogany base?

Biscuits would help align things during glue up, but other than that, if your joints are tight and you can clamp the assembly properly, you should be fine.

Well, there may be a couple of issues.

First - as you likely know - wood movement can be an issue with cross-grain joints. You are probably OK with Honduras mahogony (Swietenia macrophylla) but some of the other "mahoganies" can move quite a bit; and 12" is quite wide.

Second, if you decide to make the ends with vertical grain to avoid the first problem, you are now gluing end-grain to end-grain, which is a challenge for most glues. A possible solution is to put in a couple of small butt-blocks at the joint (not a single full-length cross-grain block, of course). This will also help with aligning the joint while gluing up, since mitre-joints made slippery with glue are awkward without such things as biscuits, splines, or dowels.

Hi,
I second all those remarks.
End grain, slippery joints, biscuits help, additional internal glued strips are a low cost and very effective solution.
The glued strips can be square or triangular (half a square).
