The New Temporary Workshop Episode 2 – Post and Beam

Working on the new Temporary Workshop, I placed the anchors the other day. My son Patrick and my friend Carl came over to help me get the frame up.

I have the posts up and Patrick is marking the lines where we will cut them. Used one of those laser levels to establish the lines. What a difference a little technology makes. This used to be done using a long piece of plastic tubing and water.

I built the beam out of 2×6’s and a 1/2” plywood center. Nice having a 75′ driveway for laying this out. I started with a 8′-2×6 and a 4′ plywood spacer. I butted a 12′ 2×6 and more plywood, until I had a 29′ beam. I built this so as to stagger the joints. Triple nailing on both sides and it is done.

Anything to do with roofs and beams, you need to crown your material. Solid wood has a natural tendency to bow, so that when you look down the edge you will see that one side has a bow in it. When this faces up, the material is crowned. This helps you when you apply material to roofs and beams. The additional weight is pushing on your structure, but it is flattening it out, rather than forming a bowl.

While waiting for Carl, we measured, and installed the joist hangers, and crowned the joists.

When Carl arrived, we hoisted the beam and screwed it in place. I used #7 Deckmate Screws which are the greatest screws for this type of work. (Yes I could have used joist nails, but I don’t like stuff falling apart)
Work went quickly, as we had pre staged everything possible. I attached the roof joist to the beam using hurricane straps and screwed them in place.

I used 12′ 2×6’s as I had a 10′ pad and my house joist was attached to the rim joist of the old roof. It has a 1′ overhang, giving me a three foot eave off the end of my project. This is Arizona. I had to cut a maximum of a 1/2” off the ends of the rafters, to square them up for the eave joist.

Here is a shot my son took as Carl and I were decking the roof. I used OSB for the roof, but I used 5/8” material as my rafters are 24” on center.

4:00 pm and the frame is done and the roof is decked. That ate up Saturday.
