Some years ago I heard about a product called "chair lock". This product claimed to tighten up chair rungs, spindles, etc by pouring it and letting it ease into holes where these parts are connected to the chair. I would like to fix some dinette chairs that have become slightly loose, but I know I would never be able to take the chair apart and start from scratch. Is there a easy way to tighten these chairs before they become more loose? Lee Ann
