alway got to put your 2 cents in mr cnc LOL

 

i use nail gun and lots of wood glue. havent came apart yet and its abused daily lol f(amilly van) its a bare box but there is alot of crap that has to sit on it. bang on it. and its still holding great

 

I have an 18 gauge brad nailer I can use . . . Or should I use a framing nailer?

 

framing nailer will destroy the mdf lol. brad nailer is fine. i think it was 18gauge nailer i was using. or was it 16??? either one anyway. i wasnt shy on nails either. 1 nail every half inch lmao

 

lol that box is more nails then wood,
if anyone here knows about building with wood its joef!

 

ya its way overkill lmao. im a finishing carpenter by hobby. i do furniture and now sub boxes. overkill is better than underkill. dont do it twice only once. thats what i go with hahahahah


next box tho is with screws

 

Yep, that's right about the glue only holding onto the surface layer of the MDF. MDF can and will pull apart in layers itself, even though it's just thought off as a mush of sawdust and glue. I don't know exactly how they make it but I'm guessing they lay it down in layers as you can see these layers separate if the wood is being pulled apart. Anyway, I built a small sub box once for an 8 and screwed and glued and then took the screws out, since I wanted to round-over the edges for a smoother edge look before carpeting. After moving the box around in and out of the vehicle a few times, one of the walls started to pull away. Had to end up brad-nailing it and then later on, put the regular screws back in.
