Enhancing our vision, especially for fine details such as those made on ornamental lathes, becomes quite useful. An Illuminated Magnifier is a very useful for that purpose. (An alternate is a set of MagEyes .)
I find it especially useful when verifying my sharpening activities.
A dust cover like the one shown in the picture to the right (flipped up) is useful in a woodworking shop.
