Universal Swingset Add-on Plans

For attachment to the Apollo, Endeavor, Triton, or Gemini Fort designs.... If you have an existing fort or playset with 4" x 4" corner post and no swings, this universal swingset add-on plan will give you the information you need to add-on 2, 3, or 4 swing positions. This add-on plan may not fit your particular structure, but it will lend you valuable information on how to construct a sturdy a-frame and where to position your swings.

Lumber, swings, or hardware are not included

Options are available... These plans will also give instructions for using the 3/8" bolt thru beam swing hanger or the ductile iron hanger (shown above). Either hanger will be sufficient to hold large children and some adults. It comes down to what you want and what you want to spend. I like the look of the ductile iron hanger and I tend to over do things. This hanger appeals to my sense of bigger is better.

You will not doubt the strength of this design... Plans are for a rugged all wood a-frame assembly and 4" x 6" swing beam. Solid 4" x 4" a-frame legs and a-frame blocks work together to hold up the 4" x 6" wood swing beam. Bolt thru beam 1/2" carriage bolts secure everything together. All recommended hardware is heavy duty 1/2" or 3/8" carriage bolt or hex bolt for added durability, strength, and peace of mind.  My all wood a-frame assembly is built to support any load your kids can dish out. The spread of the legs is greater than the height of the swing beam and legs are staked to ground to add increased strength and stability.
