I hope it's okay to post the question here for all you construction geniuses. I've been wanting to make a basic sturdy wood A-frame swingset with at least 3 swings for my boys for a long time. I have 5 4X4 posts that are 12' long and finally got some gift $$$ to buy the rest. I plan to order some metal brackets from Lowes, but don't know if I need the triangular ones or the little L-shaped ones. Or both. Also, I'm uncertain about how to connect it all together at the top. And if I should use the 4X4 for the top bar, or use a couple of 2X6s on end & screwed together. I guess a 2X4 can be used to make the cross bar for the A parts, but what is the best/safest angle? I'd love to see photos of your projects, or get links to online plans to help. I want this to last for as long as my boys want to swing, and then be used for a chicken coop. Thank you for your help!
