What would you recommend to buy as a beginner piano tuner? (equipment)
There are many tuning kits available on Amazon (for example) that include various tools depending on the package you select. My simple kit includes a tuning hammer, a felt strip to mute every other string, assorted rubber dampers, and an A-440 tuning fork. You can also get a digital tuner if you don't have the ears for tuning a piano, but that will not result in a proper 'tempered' tuning.I strongly recommend that you get some training before you even touch the insides of a piano. You can learn best from a seasoned piano tuner who is willing to give you some lessons. But that's just the basics of a tuning. Caring for a piano involves diverse skills and knowledge. There will be all sorts of little mechanical things that can break.The very most important quality you must have to tune a piano is a good ear. Normally when you tune an instrument (such as a guitar) you tune the pitches until you hear no 'beats' in the sound. A piano must have tempered tuning. That means you must get one octave of middle notes tuned so that there a proper number of beats in the overtones. You start out tuning fourths and fifths, for example. One grizzled old tuner I used once told the timing of the beats equals the timing of saying, "From Cincinnati to St. Louis." You then tune all the octaves of the middle notes until they have no beats. You will find piano tuners have eccentricities, and they vary.I have a pretty good ear for pitch but I have not mastered tempering. So I just stick with tuning the unison notes until they have no beats. That will work for a while, but eventually (every six months to a year) I have to have a professional tuner come and fix it properly. You can experiment on your own piano if you want but unless you have proper training, chances are you will end up hiring a pro to undo your mistakes.(Might be better to go with Godfrey McDonnell.

How do i teach beginner piano?
You are about the most radically unqualified asker of this question I have yet to stumble across in two years of being on Y/A. Others were teen-aged kids with at least five years of lessons. The answer is you don't - you are self-taught, and basically know so close to nothing about the piano, how to play it, the most fundamental of theory, and zilch about how to teach, a craft apart from being able to play. Your friend wants you to do it in the hopes of avoiding an additional expense. Bow out. Tell your neighbor you are entirely unprepared to teach, and her son is better off learning from someone who knows how to structure the learning progression, This is certainly what the school means and expects when they require 'piano lessons.' Recommend she inquire of the school or the band director about any affordable teachers in your area, and get back to using your time for your own self-study of the piano. Best regards.
