Bench grinder wheel dresser
Bought my first dressing tool. Both wheels on bench grinder had deep grooves in them. The dressing disc wore down to round washers in first use but still working. I decided to make my own disc from 1/4" steel plate, slugs produced from iron worker. Used 1 1/4" punch , drilled 1/4" hole through concave side made by punching plate. Grind down the convex side of washer making it possible for to install 2 washers in dressing tool. Works better and longer than original tool.
