Merkin

need some guidance on stuff i need or where/how do i get them

screw or nails?
glue? type?
internal manget bracing fitment directions (building a box for adire brahma)
sealants?
what material to seal the front side

board cutting DIY table saw or store can do it

any sites i can look up?

bbaudi382

3/4" mdf

screws

heavy duty wood glue or construction glue...i used heavy duty liquid nails.

the brahma is like 35-40 lbs right? i dont think you'll need magnet bracing, just some good wood bracing will do. if you want you can use dowels to make a brace

to seal the inside u can use wood glue also. i used something different than liquid nails. i used titebond II cuz it was easier to work with when sealing.

you can cut the boards yourself if you ahve the right tools. a store could do it fo ryou BUT i would draw the lines out and be VERY SPECIFIC as sometimes they are sloppy and make quick measurements and your final box will be off.
