For the case of the elbow is the same procedure, bind to the seat and back with the help of nails and screws at different points to support the chair while the weight of the person. I have been admiring your pallet projects lately because we have a few we’d like to tackle. They owned and operated a very small business making wood pallets for a local lumber shop.
Finish the frame by filling solid with removed pallet lengths and just grab the perfect hardware to hold tight each part and portion of chair in place!
Immediately the wood takes on the color of the mixture, however, you need to let it dry that will not ruin the clothes of those who sit. I love the idea of taking a very basic thing and making something functional and beautiful!
We grew up listening to the soothing sound of either a saw cutting the wood or both of them hammering away making the pallets!
