One of the things that bug most people as they get older is poor lighting in the shop. If you want any degree of accuracy when doing the work we do; you will need good light, and (in my case) some magnification. A few weeks ago I got what I considered a fair deal on medical magnifier with florescent lighting. It has a 5X diopter lens, and I really liked it from the start. I mounted it above my lathe, and it really helps when doing “close” work.
