Dumb box building question

[sonic purity 10+ year member]

I owned a car audio shop for about 10 years, but I closed down about 6 years ago. All of the sub boxes that I built I used wood screws and liquid nails or wood glue. I have seen a few boxes on here that seem to be held together with just wood glue and no screws. Will a sub box hold up to the pressure if you dont use wood screws to anchor it down? Or is everyone using wood screws and I just cant tell from the pics.//content.invisioncic.com/y282845/emoticons/wow.gif.23d729408e9177caa2a0ed6a2ba6588e.gif

Wood glue forms a chemical bond between the two pieces of wood, often stronger than the wood itself. Wood glue > screws //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

Some people use glue and screws, some just use glue. I use both. Up to the builder really.

Glue two pieces of MDF together, let it dry and try to break the joint. You will see that the wood breaks before the glue seam.

I use wood screws and Tite Bond II, only because I don't have a brad nailer.

I just wondered if glue is really strong enough to hold a box together by itself. I probably will always use screws also.

Thanks, I might just try that.

yes certain wood glue is stronger than the wood itself if its applied correctly,clamped and fully cured !!

If your concerned about the screws showing, just countersink them a bit, then go over the tops with wood filler and sand it all down to flush it out. Works for me

Glue works fine. Screws, if anything, make it weaker because of the voids they create. However, if you predrill, you don't have to worry about that either.

I always pre drill, if you dont it splits the wood. Plus I always counter sink em. I might go ahead and try to use just glue on my next box, I am interested to see how strong it will be.

One of the main reasons for the screws was, when trying to build a couple of boxes a day. you dont have time to let glues dry or silicon fumes air out before getting the carpet or vinyl on it and mounting the sub so it can get into the customer vehicle. But now that the only boxes I build are for my own vehicles, I can take my time

Yep, that's the only reason to use screws; they allow you to keep working when the glue hasn't cured yet.
