.020? Wow! Legendary. That is better than a plek machine!There are so many hackers out there, I did not trust anyone who was close-by and reasonable. The pros with a good name are too expensive and too long to wait. I bought and made a few tools and re-fretted my Gibson SG Custom (ebony board). Anyone with some manual dexterity and good vision can do it. I made my own sanding beam using a cheap level. I first got a good Stewmac straight edge and took it to the home improvement store. Most levels are truly flat. I did the same when looking for files. The best work is the use of under string levelers. My action can be as low as 0.020" at the 12th fret using these. Definitely practice on a cheap yard sale neck. You learn a lot without messing up your nice guitar.
