Birch box construction

That is after I pre-drill with counter sink I put in a dab of glue.As well as gluing the edges not just glue in the holes sorry.

You NEED to pre-drill w/ MDF... Even when screwing two scrap pieces together... It just doesn't work unless you pre-drill...
Just make draw a line across where that you want all your holes on... Pre-drilling is easier than drilling the screws in...

i know that.

im asking do you pre drill before the glue or while the clamps are holding the glued pieces together?

i always just used clamps alone, so i dont know. //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

OHHHH. Gotchya.

He's talking about EXTRA glue. Yes of course still glue the entire edge together, but he ALSO puts glue on the screws... Holds them in tighter, and would make it more airtight.

You can still make a good box by simply using ONLY screws through the entire box.. then sealing all tha edges/corners w/glue.. (Liquid Nails is my preference)

& no, I don't CARE what kind of glue YOU use or what kind of glue YOU think is better. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

All this talk about screws backing themselves out & the bond between the glue & wood breaking.. is bullshit.

You know how hard it is to pull that shit apart? Yeah.. your sub isn't going to do it.

Only thing I've EVER seen like that is a sub backing it's mounting screws out..

Or stratusrt01 had a folded horn that he only used glue & brad nails.. & the side of the compression chamber came off..

Correct this is just a little insurance that everything is thight and well bonded.I don't think everyone does it but hey can't hurt anything.

Wrong. You build shitty boxes if you build em that way. I know thats how I started building em. I finally moved on to wood glue and it makes a world of difference //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Most failures are from improper bracing which causes joint failure due to unwanted vibrations.

I don't build my boxes like that..

BUT my past 2 boxes (DD 3515 & HD3 15") I've built w/only screws, no glue.. then Liquid Nailed it to seal it inside..

Not a single problem. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

NO air leaks.. at ALL.. can't really deny it.. or disagree, I've had good luck with it..

Does it work, Yes.

Would it work if i ran 8 gauge power wire to my saz 3000ds. Sure, Is it optimal of coarse not //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

And I think someone did a test and found wood glue to be far superior to liquid nails(the choice of beginners).

Sure you can do that, but what's the point?

For the money you spent on liquid nails you could buy a TON more wood glue and use that along with the screws.

Wood glue is way cheaper than liquid nails.

And fyi, I have broken a joint that was screwed AND glued because the box flexed too much. A little threaded rod took care of that. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

It works just fine if you don't predrill. It is just more difficult and more tedious.

Don't ever give advice to this forum on this topic. You are blatantly wrong, and there are published articles by people from woodworkers to materials engineers that state that wood glue is the strongest way to bond wood.

It is stronger than anything else besides wood-wood joints (dowels, dovetails, biscuits, etc).

I guess if you can hold it down... It's hard to be accurate while pushing down with allot of force..

But I guess your right, it's possible, just not ideal.

Also he was NOT arguing that wood glue was not the strongest.. He was arguing that you don't NEED wood glue to make a decent box.
