  • Max beam span kids fort

    Hi. Thanks for everyone's advice on my post situation. My question is now this - I was going to use 12' long double 2x10" beams to span 11' between posts. After some pontification I've come to the conclusion that won't be enough. Will double 2x12s work? Triple 2x12s?

    I'd have to see your plans, could you post a drawing?

      Ended up using 3 2x12s on each side to cover the 11" span. Should be sufficient

            All depends on the wood used, the calculated live (max number of kids) and
            dead (weight of fort components that bear on the beams) loads, and maybe more
            important, how you connect the beam to the posts (nailed, bolted, joist hangers, etc.).

                Lets see , what size tires for My vehicle ? Vespa Scooter or Lincoln Town Car ? Doubled up , back to back 2"x12 " channel iron should be safe . Skip weld with 3/16 " 7018 every 6 "
                I can build anything You want , if you draw a picture of it , on the back of a big enough check .

                  A W12X22 beam should span 12 feet of children playing just fine....LOL

                    a typical re-enforcing trick we use is to sandwich a plate of 1/8 steel between the 2 x 12 (the 2x12 keep the 1/8 plate from bending) and this arrangement supports a lot of weight
                    shooting the s*** is a lot more fun when you use hollow points (much more splatter)
