How do you rebuild a plastic saxophone? Very, very carefully. What seemed like a good idea for an economical, alternative material in the 1950’s presents quite an undertaking to restore today.
The plastic in the body tube of a Grafton won’t dent, but it will crack and will melt. Graftons don’t use needle springs, rather wound springs like in a watch. Lots of fun to take apart, put back together, and adjust. Spares aren’t available. Lots of patience is required. I’ve restored about a half dozen of these horns. Each time I’m relieved when they’re done.
This particular alto was a great example to save. Now it plays as good as it looks.
