I built this swing for my wife for mothers day this year. Its up on blocks in my not-so-level yard for the moment until I build my island deck.
Basic treated lumber, stained with Minwax Provincial and 2 coats of Thompson's water seal. I'll cut the chains off after I get it set up on my island...
Garden swing, inspired by my neighbor's respective piece.
The seat is heat-treated aspen, and the structure is pressure-treated (thanks Travw) pine.
There is absolutely no squeaking, as the axels for the chains have ball-bearings, hand made by the said neighbor.
