mdf
Wienerdog:
20%... sorry, I was just stating the obvious. 3/4" is 20% heavier than 5/8" but your cab has lots of weight from the monitor, computer, controls, etc. I'd honestly consider 5/8, because 3/4" is just SOOOO heavy. A full 3/4" sheet of MDF is around 90 to 100lbs.
crashwg:
The density of the core is expressed as the weight of a one cubic foot (1'x1'x1') block of the material. Therefore, an MDF sheet using a 48# (pound) core, will weigh 102 pounds. (49"x97"x3/4"= 2-1/8 cubic feet)
A 5/8" sheet of the same 48# core would weigh 78 pounds (49"x97"x3/4"=1-5/8 cubic feet)
Lets say you use 3 sheets of mdf on your cab. 3/4" will make your cab weigh 306# and 5/8" will make it weigh 234#.
Only question that remains is which is more important to you, 72# or the beefyness/extra strength of 3/4".
;)
the3eyedblindman:
if you put casters on the cab, weight wont be that big of an issue.
cholin:
Even with casters, 72 pounds is a big difference.
Witchboard:
Since you're building with MDF, I would go 3/4". If you were building with plywood, I would suggest 5/8". Just my prefs.
