I'm a bit curious how he's using feeler gages to estimate surface

One buys the 70$ surface roughness "feel" gages and compares -
strictly a qualitative measurement.

Sorry, I thought you said "feeler gages".
I was about to offer you my surface thingie gratis (if I
still have it & can find it) but it sounds like you already
have one. Electroformed bit, right?
Up to US$ 70 are they whoosh?

Mine was a free sample from a machine tool manufacturer - but if you
were to buy one they do run up to 70$.
