In a comment on the post about refurbishing the Disston saw, Ralph mentioned he had trouble focusing on things that small. I’m not sure whether “focus” meant a real vision problem, or interest that wanders away. If a vision problem, this might help…
I’m shamelessly stealing the idea from Megan Fitzpatrick who recently wrote about updating her bench. She included pictures of how a ubiquitous magnifying lamp was adapted for use on the workbench. The lamp stands on a column 1/2 inch in diameter. My bench as a whole bunch of 3/4 inch holes for holdfasts. I took a block of scrap 2 by something. drilled a 1/2″ hole all the way through, flipped it over and drilled a 3/4″ hole most of the way through, and glued a 3/4″ piece of dowel in that hole. Now, I can locate that magnifying lamp almost anywhere.
