This project came about after I picked up a few Eames fiberglass chairs that needed new mounts. The shock mounts on these chairs are often cracked and squished after 30+ years of use, or the glue has failed and they've fallen off.
If you already have shock mounts, skip to the last step of this Instructable for Installation tips. The remaining steps will show you how to make your own mounts.
Since I had 4 chairs that needed new mounts, making them myself was a lot cheaper than buying reproductions. There's no waiting for shipping, I can have the mounts the next day, and I can control the quality myself. Aside from the mold rubber, the only cost is the weld nuts ($1.63 each for Stainless Steel or $.74 each for Zinc Plated). Stainless weld nuts are an improvement over reproduction or even the original mounts, because they won't rust if the chairs are being used outdoors.
