    Free plans to build a beam bench from ana-white.com Follow Ana on Pinterest! About Project Author Notes:  Hi everyone!  I'm so excited today to share with you brand new plans! Remember a little while back when I teamed up with Shanty2Chic to get you plans for this truss table? And we promised you bench plans were coming soon? Well, we are very happy to come through on that promise to you today!!! Whitney from Shanty2Chic and I teamed up again so you too can build matching benches for your table! Here's from Whitney : I am LOVING my new benches!  I love the simplicity of them and how the design compliments the table so well.  The 4x4's give it a really solid look and my whole family can eat at this table at the same time.  The best part… Under $80 in wood for both.  Can't beat that! For more building details and finishing instruction, please stop over and check out Whitney's post over at Shanty2Chic - see you back here for plans following! XO Ana Materials and Tools Shopping List:  2 - 4x4 @ 8 feet long 2 - 2x4 @ 6 feet long (or a 12 footer) 2 - 2x8 @ 6 feet long (or a 12 footer) 1 - 2x10 @ 3 feet long (for the breadboard ends - you can also use 2x8 scraps here instead of buying a 2x10) 2 1/2" pocket hole screws Tools:  measuring tape square pencil safety glasses hearing protection drill compound miter saw sander Cut List Cut List:  2 - 4x4 @ 13 1/2" 4 - 4x4 @ 13 1/4" (long point to long point, both ends cut at 10 degrees off square, parallel) 2 - 4x4 @ 8" (long point to long point, both ends cut at 10 degrees off square NOT parallel) 1 - 4x4 @ 65" 2 - 2x4 @ 65" 2 - 2x8 @ 68 1/2" 2 - 2x10 @ 14 1/2" Step 1 Build two of the leg ends as shown above. There's a ton of different ways to join 4x4s - I really like how Whitney used a Kreg Jig to hide the joints underneath - check that out here. Step 2 Then attach the bottom stretcher to the two legs ... Step 3 Next, add the two side aprons - these will give structure to the seat and look like 4x4s from the outside. TIP: Drill 1 1/2" pocket holes facing upward on the inside of the aprons before attaching for attaching the bench top in the next step. Step 4 Finally, build your bench top first (I recommend building with 1 1/2" pocket holes and 2 1/2" pocket hole screws first) and then attach to the bench. Finishing Instructions Preparation Instructions:  Fill all holes with wood filler and let dry. Apply additional coats of wood filler as needed. When wood filler is completely dry, sand the project in the direction of the wood grain with 120 grit sandpaper. Vacuum sanded project to remove sanding residue. Remove all sanding residue on work surfaces as well. Wipe project clean with damp cloth. It is always recommended to apply a test coat on a hidden area or scrap piece to ensure color evenness and adhesion. Use primer or wood conditioner as needed. May I Suggest a Finish?

  6. Week 6 Journal: Finally Making Some Progress

    Blog

    FromPosts tagged: bathroom

    It finally feels like we're making some real progress on the Curbly House . After weeks of demolition (and basically just making the house  worse  than it already was), this was the first week where we actually started  improving  things. Read on to watch my weekly video journal and read about all of our framing adventures. If you haven't been following along, just a reminder that so far we've demolished all the ceilings on the first floor, as well as the ceilings in two bedrooms on the second floor. This exposed a bunch of structural problems that we never would have known about, but really needed to be fixed. So this week, we started upstairs. We 'sistered' every single ceiling joist (technically these are called "collar ties"). Sistering is where you reinforce an old structural support by putting a new one in beside it. The joists in the bedrooms were sagging up to four inches in some spots, and a few were cracked right through.  Sistering the joists will level out the ceilings upstairs and let us sleep soundly knowing the attic isn't going to collapse on us. Next, we moved downstairs into the music room. This room isn't original to the house; it was created when somebody knocked out an exterior wall into the porch, and converted that into a living space. Unfortunately, when they did it, they left the framing in disarray.  So we cut journals into the walls, added posts on both sides, and threw in a giant 4-ply 2x6 header. We engineered this header to take 60,000 pounds of load. We also jacked the house up about three inches when we put it in, flattening out the floor of the bedroom above (bye-bye, roller coaster floors!). The framing under the bathroom was also a mess, and we needed space to run our new plumbing. So we ripped out most of the old stuff, and re-framed the ceiling with 2-ply 2x8 joists . In doing so, we created a new 16-inch wide chase in which we'll be able to run our new plumbing. No more raised bathroom floor! Last, we ripped out the doorway and closet that separated the living room from the kitchen. We want the whole downstairs to be open, like a big donut centered on the fireplace. After ripping out the old entryway, we added a new header that will let us create the opening we need. Whew! That's what I call progress! Check back next week to see what trouble we get into next on The Curbly House!  This is a post in  the Curbly House series ! Follow along as we document every step of our complete home makeover, from gutting the walls to putting up the finishing touches. And don't forget to let us know what you think in the comments!
