Yeah, start with those and add a flip down set of auxiliary
magnifying lenses. My eyesight has never been great and
age, injury, and surgery haven't helped things. So I keep a
set of moderatly magnifying eyeglasses in the shop with an
old (OT content: Bought 'em at a MWTCA meet) flip down
lens set added. Works good for a lot of things. Plus teeth as
fine as you're dealing with here are just darn small. Don't think
I've done anything finer than 11/12 tpi or so, and that was much
less fun than a nice 6 tpi'er.
