I Built a $12,000 Outdoor Patio Sectional for $997

What happens here

After cutting, the creator identifies several pieces of Douglas Fir lumber that are warped or 'cupping'. He explains that these need to be flattened for a high-quality finish. Before feeding the lumber into the Ridgid thickness planer, he carefully removes any embedded staples using a screwdriver and pliers to protect the planer's blades from damage. He then runs the lumber through the planer to achieve uniform thickness and straight, square edges, which will give the sectional a 'luxury' rather than 'dimensional lumber' appearance. This process also generates a significant amount of sawdust.

Goal: Correct warped lumber and create smooth, square edges for a refined finish.

Tools and materials

  • Pliers — Pulling out stubborn staples
  • Screwdriver — Prying out staples from lumber
  • Thickness Planer Ridgid — Flattening warped lumber and creating uniform thickness
  • Douglas Fir Lumber — Lumber to be planed and squared

What they say

Hide

chopping all the wood up. So, for this project we're going with a Douglas fir. Now, don't worry. Douglas fir is one of the hardest things to stain just cuz of the red pigment inside of it, but we're going to be painting this. But, we still need to kind of flatten some of these things out. Like this one's kind of cupping right there. I have my thickness planer here that we can fix that problem, but to make sure that you take care of your equipment, make sure you remove any of these staples that are in the wood. Um and don't just prime out or try to prime out with your screwdriver. Um I like to lift them a little bit, but then use your pliers. And the reason why is if you break up a piece of one of these and still in there and you run it through your joiner or thickness planer, you can say goodbye to those knives. They're gone. You're going to have to get new ones and get that re-sharpened. So, >> [sighs] >> and then ask me how I know that. Cuz I've been there. And in fact, the joiner that's right behind Kyle that's standing there, uh it's creating a bunch of different cuts and grooves. So, I got a new set of blades that's sitting right there. Let me pull these out. We'll flatten them out and then I'm going to trim off any of these round over edges just so we get nice clean lines cuz we want this thing to look luxury and not just out of dimensional lumber.
