Making a box for a 12

[nathanh 10+ year member]

use gorilla glue. it expands as it dries so it ensures a good seal. not to mention it makes a bond that is stronger than the mdf itself. you need to use screws tho so you get some clamping pressure.

... gorilla glue needs to die. a 45 rip on all 4 sides with a sparing about of rolled yellow glue will give you a hold that will bond tighter and stronger than the wood. i have used gorilla glue and it doesn't penitrate like yellow glue so it wont bond to all the fibers. and white glue sets up way to fast for a box build. any yellow glue will work, tightbond, elmers... same shit. I, II, III... doesnt matter. i have fabricated countless mdf mantles and used all sorts of glue and other bonding agents...

epoxies vs. glue... doesn't matter, any yellow glue will do. i have fabricated many radius hand rails and skirt boards and epoxy is harder to use and does the same.

now for filling gaps, epoxy is great, cause yellow glue wont bond unless it is a tight fit... any gaps and all integrity is shot... one down side to yellow and white glue.

construction adhesive is probably the worst you can use unless it's pollyurithane... liquid nails is garbage.

pallyurithane will penitrate well into the wood but regular stuff is garbage. it is too thick to use so your joints will gap and your box will expand.

little fyi on glue.

Im not that you are saying this or not but just to clarify gorilla glue is not technically an epoxy.

if you didnt get good penetration with gorilla glue then you didnt read the directions.

it has more penetrating power than all the others because you are supposed to dampen the surface before applying the glue. the water seeps into the wood farther and faster than any glue will and then the glue slightly dissolves into the water meaning that the glue is pulled into the fibers of the wood. the water also in necessary for the chemical reaction to occur so that the gorilla glue will expand and harden. without the water the glue is weak. Pressure is a must however because the expansion can actually separate parts. the joints are also stronger than the wood, if you read my other post about it you would have seen what happened to me.

not to mention that gorilla glue will work on just about anything you can think, except for rubber, ive tried it and ill tell you dont use it. its my go to glue after super glue since its not clear. but for building boxes i wont use anything else. plus it guarentee's a seal without having to caulk, even tho i caulk all my boxes anyways.

but enough about glue. go build a box. its a great learning experience at the least. and i think its fun.
