Every finish carpenter has dividers they use most every day on the job. I used a cheap set of Stanley's for years until a brother got a nice set for me at a flea market (the set in the middle). Then my BUDDY (and longtime partner) Jim Rebello gave me a set of dividers that he had made. I want to tell you, these are the best. They are my go to pair everytime. Green paint (his) and all- note the Rebello signature on the side.
