OT swingsets
My kids need a new swingset. I am wanting to build one. Any
suggestions? I mean should I just find one and copy it, buy a book? Anyone have any plans or pictures? |

They aren't that tough an engineering challenge - but go look at commercial versions for design cues. Especially the public park models, they are made to take rough use. Don't try making your own seats, it's like reinventing the wheel, too many design variables. The public park style vulcanized rubber seats can't be that expensive to buy AFAICT. You have to make them strong - because when chains fail and attachments detach, your kid could get seriously hurt. Beefy hardware, and chains rated for more than you would guess - centripetal forces plus two kids on one seat, and you have a ton of force... Gusset and over-engineer the A connections to the main cross pole, for the proper rigidity - because kids do climb up on top and use it as monkey bars it has to be way strong. And anchor down the legs, because the whole thing can fall over. You have to studiously avoid pinch points and finger trap points - a "degloving" injury is as horrible as it sounds. Everything needs to be streamlined and enclosed. Pad all the poles - standard foam pipe padding and pipe-wrap tape. -- Bruce -- |

Most sets you can buy are poorly designed. Go commerial quality. Another hint...if you are HSMer build the A frame heavy enough so you can use it with a hoist to lift heavy items. I know more than one HSMer who has "built" a swingset to camoflage a gantry crane in the neighborhood. TMT |

When my mother was little she stuck her finger in one of the chain links and somehow got a strip skin ripped loose most of the top of her finger. They stuck it back down and it healed fortunantly. I think I got told about that the first day I was on a swing. Everyone's talking about the swingset itself but no one has mentioned the surface underneath. It needs to be sand or some other soft surface and if it's swingset is set in concrete then the concrete needs to be buried under the soft surface. Not that I've ever jumped off a swing at the highest point or anything. Karl |
