Wood Glue or PL
 

I was wondering what everyone uses and why 1 local shop says wood glue the other says PL premium or liquid nails i was just curious as to what was the better/stronger choice

my opinion would be pl premium/liquid nails for sure

in case you use pl
 

Just don't get that stuff on your clothes or hands.
It's a b to get out if you can get it out....

the Pl premium is quite the thing to use to bond stuff yet I have not used it on building boxes....

Thanx for the quick replies guys

I use Carpenter's Glue..it tacks up faster than regular white
glue and has a higher tensile strength...
Liquid nails works but the cost is much higher and it is alot harder
to clean up

PL Premium is all I use. For most sub boxes, just glue the pieces and brad nail to keep it together till the glue sets. Otherwise I screw and glue. Stuff works sweet!

You'll get as many conflicting answers here as at different shops. IMO if you can create tight joints then wood glue is all that is needed. If you're cuts are not so good then thicker goop like PL is a better idea.

45 degree corners are you friend,, if you can get them perfect.

Long clamps and glue,, I use Weldbond white glue,, never failed me yet!

Using a brad nailer is good,, Biscuit jointing is the ****! If you can afford a Biscuit jointer router and the biscuits are not cheap either,, but you'll have a joint that's bullet proof!

Screw and glue requires (in MDF) pre drilling, and if your finishing, and I recommend anyways, counter sinking. Screw and glue will give you a strong joint, but you might bow your wood in the screw area.

You can also recess your joints (dato) joint is what's it's call I believe.
commonly used in shelving, and super strong as the one piece locks into the other, glue, nail or screw.

As mentioned, if you use glue and you have some gaps, you're going to need to sillycone to fill,, or if you use PL off the start, it;ll fill the little gaps you made.

But,, if you take your time, measure twice, cut once, use sharp tools and have a little know how, you should come out with a nice product.

If you like the way your box sounds, you can always coat the interior of the box with fiberglass resin. It'll soak into the MDF and seal the whole box up, and provide another layer of stiffness. You can re-inforce the corners with matting or cloth if you want, but essentially, by coating the interior of the box with resin, you'll make a box in a box, and it'll smooth too.

thank you everyone for your input its all apreciated

woodworker magazine did tests on about 30 kinds of glue and the far above the rest winner is regular old yellow elmers wood glue

that i all i use and 18 awg brad nails hold it together till the glue dries the only screws you should use are to hold the woofer in also never screw in to the end of a piece of mdf or plywood


pl construction is for people that ant cut straight and gorilla glue expands so keep away from them
