cut list for 2x4 sofa
Hi! I previously made two of these sofas into a sectional (amazing, easy, everyone loves them) and I'm planning on adding a third this weekend to make a u shape sectional. My question is: Do you have a cut list for the 11 2x4's? I used more than 11 each time. and I also had alot of waste...

I'm so glad to hear! Maybe…
I'm so glad to hear!
Maybe try cutting all your long cuts first (the 72" ones) and then from the scrap pieces, cut the shorter arm/legs pieces

Cut your 9 2x4x10 at 72”…
Cut your 9 2x4x10 at 72” first, then use scraps for 25 1/2
use the 10th 2x4x10 to cut the 4 other 25 1/2
the last 2x4 could be only 6” as you will cut your 2 last at 28 1/2
That’s 10 - 2x4x10 and 1 - 2x4x6 with 11 scraps (9x 22.5 - 1x19 - 1x15)
it is plenty!

Your cut list is deceiving…
Your cut list is deceiving. If I’m building to suit specific cushions I don’t need 13 pieces that length. 4 of them still need to be the length of the height of the arms. Kind of a pain in the ass when you’ve pre stained/sealed based on the cut list and then end up with pieces that won’t work.

Hmmmmm.... did you use…
Hmmmmm.... did you use 2x4x10? Because the only way you would end up with 13 unusable pieces would be if you used 2x4x8 . One thing about Ana I noticed is all her plans Minimize scraps, if any at all.

Thank you for this build. I just built the couch last night. My only question is this:
Step 5 doesn't have any instructions. It's kind of self explanatory as to how to connect the arms in Step 4 to the seat base of the couch, but what isn't clear is how many screws to use? I only attached the arms to the seat with 3, #10, 2 1/2" wood screws. So that's 3 wood screws on each arm holding up a lot of weight when you take into account the weight of the top of the couch and anyone sitting on the couch.Is this enough to hold the weight?.... or should I find a place to bolt the arms to the seat.
That particular piece of wood in Step 4 already has a ton of screws in it. It has pocket screws in each end and pockets screws in the side to attach it to the board in Step 3, and then it has 3 wood screws attaching it to the seat base.
Any help?
