The idea that machine work is some genie in a bottle is simply insane. You can certainly learn to do it yourself. I do a lot of my own cylinder head work. I've never posted it on here and never will, because I use old school methods such as stones and diamond sharpeners. Those who suck the serdi's balls would make fun of me so you'll never see me post up. I thought about doing a how to, but no way in hell.
