How to convert 9/16" tuner for 11/16" hole.

So I have these old Grover Wavy Titans and wanted to put them on my Geddy Neck, the issue was that the Geddy tuners have an 11/16" bushing and the Grovers are 9/16". I scoured TB and found some helpful advice and figured i'd post a "how to" with pics - a culmination of my research.

First, here's the headstock with original chrome Fender tuners - I actually might switch back because they really do look great.

I read in some posts that people filled the space with some plastic pipe from Home Depot, I couldn't find one that worked, but I bought some vinyl tubing (.5" ID) that fit the specs pretty well. Here's the tube I purchased:

It's a little snug on the Grover tuner, so I cut two small slits for relief at the ends. Put the washer on FIRST as you won't be able to fit it over the tubing.

Cut excess tub, push the new wider tuner into your existing 11/16", tighten the nut and you're done!

I did a similar thing on a bass except I used short lengths of brass tubing. I found a piece with the right outside diameter and drilled out the inside to the needed diameter. Worked great and you can't even see it from the outside.

how is this holding up? did the tubing deform?
