I received an email from one of our ShopNotes kit customers concerning how to install our backs. The method another vendor uses generally will not work well as our backs typically hold a bit tighter–and correspondingly are more difficult to install.
When we got in this morning, I photographed one of the boys illustrating how we install a folded brass back.
