Yeah, that's what I was taught, used it numerous times. You're then measuring the wavelength of the light. or some such.light between the part and square will actual turn a blue when within tenths.

Can you direct me to which episode on YouTube he mentions this? I didn't see one that mentioned this directly.
depends on how much weight you apply, use kero or wd40 on soft metals, but you,ve only got to see how many shavings come off when ,say, filing an axe to see how much, btw never file both ways pressure on the away stroke, files are not cheap, as with a hacksaw just pressure on way, lift the tool slightly on back stroke, trade schools are no more here, probs they did not teach these things, but they did 56 years back)Also how much does a file remove on average for fine file and bastard cut file.

Is there any numbers as a reference
I remember looking at others forun stating oil will only cause file to glide and use chalk instead.He means soft metals like aluminum, be careful with oil on steel. Some steels (I.E. 4140 and tool steels) can glaze over with oils, even oil from rubbing your fingers over the work, and your file will just slide over the surface. Not good for the life of the teeth on the file.
i do it by bringing the surface quite flat with conventional technique by holding my file close to my torso and move my body instead and when im nearly flat i and square i will use the curved part of a needle file to file down the hump and its a bit of guess work and leaves frustrated me every time when i dealt with a problem and another shows up.t
here are ways n ways of filing, draw file in the start and yes you can file true, dead true, needs practice, n thas all I have to say 'bout that)
