Where did you come up with a 4-5 lb savings???
By your own weights its 3.1 lb lighter, and thats without the front - or any kind of slide either.
Your math doesn't add up, no pun intended.
The math figures like this. The smaller drawer is roughly 18x18". With a weight of 6.39 lbs, that figures to .01972 lbs per sq inch. 6.39 / 324. (18*18=324).
The drawer I need is roughly 20 x 24", or 480 sq inches, and only weighs 3.74 lbs, for 480 sq inches.
Taking the .01972 lbs per sq inch, multiplying it by the 480 sq inches that I need for the drawer, and we now have approx 9.4656 lbs for a drawer built like the smaller one, but in the larger size that I need.
9.4656 - 3.74 = 5.7256 lbs difference in weight for the same size drawer.
That's how I arrived at the difference, for the approx same size drawer, which they are not, at the moment.
I think you're being overly optimistic, but hey - its your project!
Gotta remember, you still haven't added a front, which individually is the heaviest piece in the drawer, and will need to be bigger on yours. You also, again, don't have any type of slide attached, which, simply by your increased size, will need to be more robust with your bigger drawer.
In the big picture none of this will ever matter but it is amusing.
In addition to the weight is the extra expense. I can buy 1/4" plywood for $18.00, and the 1/2" is about $60.00. I will need about 5 sheets for all the components for the drawers and the slide mechanisms if I use the wooden ones.
$90.00 vs $300.00. Yea, I'll test just a little.
