Topic tags/keywords: design question

I’m designing a cart/enclosure for my BBQ smoker (a Weber Smoky Mountain). I’m envisioning the unit being roughly 3’ high by 3’ deep by 8’ wide.

Which is better—building two 3×3 frames and connecting them using 8’ stringers, or building two 3×8 frames and connecting them with 3’ stringers? Is there a construction/strength reason for doing one over the other, or is ti largely a matter of aesthetics?

It’s your design and you know what kind of lumber is available. If you can get straight 8’ lumber go with 8’, if not go with shorter.

Do you have a picture? Stringer?

Building the 3’ x 3’ frames first and then connecting them with the 8’ rails might be easier. The 3’ x 3’ frames would be easier for me to handle during construction. I can think of no structural advantage of building one sized frame over the over first.

I say six of one, half dozen of the other. You’re really just talking about where the joint occurs, and if it’s not a unit being pushed or pulled around I don’t think it matters.

I realize my cart is lighter weight and considerably smaller than your plan, but it is simply four face frames attached together with a wall in the middle to add support.

I used cedar along with cedar fence pickets planed so they are sorta smooth and edged with a chamfer bit to resemble bead board.

Like already said, got any plans we can see?

Here is my project post. —>
