Pallet Reclaim Swing
I work for a large manufacturing company that frequently has 'desirable trash'. Found 3 beautiful, heavy-duty pallets with beautiful wood on them. Took them home, took them apart, and got to work. The wife had been wanting a swing out near our children's playset so she could sit and watch them. Used Kreg pocket holes for everything that I could so as to hide as much hardware as possible.
*Side note regarding why I did the rope the way I did - the original post had mentions of it being a bit tipsy (particularly with little ones!). With this design, there's no flip front or back and the rope only gets tighter the more weight that is applied.
