A taller porch chair!
Our problem is that our nearly new, comfortable porch chairs are too low and the wooden rail is a bit too high for us to enjoy the view. I'd like to add 5" to the 7/8" OD anodized aluminum legs by sliding another piece of tubing over what we have and then fastening it securely. What type of material that has a 7/8" ID should I use? Or can you suggest another way to heighten our chairs? Thank you,
While you may luck out and find just the right size material at a local home store, if you don't find it there than any metal fab shop should have exactly what you need. Sounds like the best way is an aluminum tube that fits over your existing legs. Give it a couple of inches overlap and a couple of bolts and you should have taller chairs.
Also, you need to use either aluminum or stainless steel tubing. If you use carbon steel and attach it to aluminum, you will get what is called bi-metallic corrosion. The aluminum risers should be attached with stainless steel or brass fasteners for the same reason.
You cam make a wood insert about 6 inch long, of a rot resistant wood dowel that matches the inside diameter od of the chair leg. Insert it about 3 inchs, and secure it with stainless steel screws or nails, then insert the remaining dowel into a matching piece of aluminum tubing
