Yes, it's actually 3/4"

I actually had a discussion with a coworker the other day about how stupid the naming convention is for lumber (ex. 2x4)

a 2x4 is actually 1.5"ish by 3.5"s ish because when it is made, it is rough cat at 2x4 then planed down. MDF is man made and not naturally occuring in nature as far as i know so its what it should be since it doesnt need ot be planed.

depends what kind of mdf you get. if u buy it as Ultra Light mdf its about 11/16" but most home depot MDF is indeed 3/4" some are about 1/32 off

he merely used a 2x4 as a ref. he knew that it was not exactly 2"x4".... not sure if he knew why but that's besides the fact. he asked if MDF was indeed 3/4" which was answered. lulz

Well I have a sheet of 5/8" MDF. It's just for 2 13w1's with little power, so I should be alright.

Anyone want to check my math for my cutlist?

Box is 33" wide x 13" deep x 16" High

Cutlist based on 5/8" MDF

2 pcs 33" x 16" front and back of box

2 pcs 33" x 13" top and bottom

2 pcs 14 3/4" x 13" sides

Just make sure and brace it well and it should be fine...

Not gonna work if you want it to be 16"h and 13"d. Might want to subtract the 1.25" of thickness from somewhere //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
