By popular demand. Here's my installation guide. I've installed many of these on new necks and older necks. It's not that difficult installing them. My recommended install is without the Roll pin that is designed to keep the tuner from spinning. Why I don't use the roll pin? It's not required. The last 9 or 10 sets I have installed in recent history have had loose roll pins in the tuner body. They can cant from side to side and drive you nuts during the installation. Years ago, the roll pins were so tight in Sperzel's you couldn't get them out. I guess with the current production is making them with a looser fit. I used a Dremel cutoff wheel to cut it flush with the tuner housing. Nowdays, they pull rather easily with needle nosed pliers. This is not saying these tuners are problematic. They are flat awesome!
I'm going to mention Stewart MacDonald as a supplier here. They have supplied me for years with quality parts. (

Tools -
7/16" socket and handle or wrench.
Peg reamer (if needed)
Calipers or ruler
1. Remove the existing tuners. Determine the tuner hole size. Most newer guitars are coming with 10mm diameter tuner holes. Older guitars or vintage replica types have vintage sizing and often use a push in bushing. The vintage sizing is usually much smaller. 10mm is what's needed for Sperzels, Schaller, Planet Waves and most Grovers. (10mm or .390" is fine)
Reaming (again, if required). These are tapered, so I go from both sides. These are also self centering reamers. A nice touch.
