Thanks

1-5/8'' drywall screws and titebond II or elmers probond will do the trick.

coarse thread drywall screws...don't need to be very long. And pre-drill before using them.

Yea I get 1 5/8 or 2" coarse dry wall screws and tite bond 2 from lowes or home depot. And +1 on the screws are just there to let the glue dry)thats what holds the box)

I only use 1.25" screws now, the primeguard ones from grip-rite (grey box, not the orange box). They seem to countersink a lot easier than the orange ones do.

Just get a counter sink bit and use it while predrilling so u have a better chance in not splitting the mdf

Titebond II or III, if someone in Home Depot hasn't heard of Titebond glue, they are a retard and go find someone else who knows what they are talking about. It is in the area of the paint/caulking/stain.

Get 1 or 2. Unless you're working in Alaska or have to bond together speakers being crushed by a semi, T3 is a complete waste of money. I use T1 and T2 regularly, the only difference being how much time I have: T1 dries faster and sands easier, T2 is a better bond and dries aesthetically clearer. Both bond stronger than wood, and I've run enclosures for 3 18s with T1 and enclosures for 1 3" driver with T3 so it all depends on the environment and your time, not the application.

I use my brad nailer to hold the box together till the glue drys. Once its dry the glue will be way sronger than the glue. I have used several types of glue and never had any problems, elmers, tb, tbII, Gorilla glue and GG wood glue, and liquid nails. Nothing seemed to perform better than others but most was with ported boxes.

i use this glue, you will distroy the mdf to get it apart after it dries. I also use a brad nailer 1 1/2" to hold it all together till the glue sets up

I used liquid nails back in highschool. That was like 10 years ago. That was for a pair of soundstream spl 10"s on a 1k rubicon sealed. But like I said I never had a problem with sealing or box coming apart. Plus the wood glue is cheaper.

Use tite bond it's better and studies show this. Some ppl on here have done tests with the glues and shown tb is best

Liquid nails is a construction adhesive. It makes a physical bond with the wood pieces. Wood glue makes a mechanical bond (chemically fuses the wood together) which is leagues stronger.

Titebond glues are stronger than the elmers wood glues, although all are strong enough for any enclosure. :( I can't find elmer's pro-bond anymore. It used to be my go-to for the winter months since it's about the same as T2 as far as performance, except it has a much lower working temperature.

tite bond and brad nails....I HATE SCREWS.....if you use screws and decide to router the edges the screws will F up the router bit.....Brad nails will not hurt router bits.

tite bond has been shown to be one of the strongest wood glues...

if you use real router bits the slight amount of screw head will not hurt it and if it does you have them sharpened lol

you can find high end router bits online on sale all the time if you look
they use the same type of hardened c3 and c4 carbide tooling for metal work as they do on good quality R bits, but if you use off the shelf hardware store bits i can see why you dont like doing it. i router right thru screw heads all the time on cabinets usually it is due to my screws being a tad to close to the edge

LN works titebond is superior tho

Hmm, didn't know that. It's all I've ever used and I've never had a problem...I just like it because it's thicker than regular wood glue and doesn't run all over the place

No matter what type of router bits being used, I'd rather not have them hitting metal screws and having sparks fly. IIRC, they were made to cut wood.

if you look closely at a metal router bit what do you see different?
nothing but the name they are made from the same c3 and c4 hardened carbide tool steel only the bit itself looks different my brother is a cnc machinist and gives me all his worn down round over bits that i have sharpened and reuse for wood his bit looks no dif than my 65$ rockler bits no dif at all

Thank you james bang............I use really good bits thank you Sic No matter what bit you use its better for the router to hit brad nails than screws....besides screws take toooooo long and f up the edges of the box if not done right.......besides who uses screws anymore.

i glue screw and brad nail/ clamp every box i make, which is quite a few lolz

it is never good to hit a screw it is very dangerous, but it does happen now and then which is why i use the best bits i can afford.
