CMP brake question

[Grant Bowker]

I suggest caution cutting a spring for this application from a longer coil as the springs I have seen for the snail adjusters have flat, closed and ground ends. I believe most springs of similar dimensions (free length, wire diameter and number of turns) will behave similarly unless there is a large difference in the material properties. I have found several springs wanted for CMP projects at https://www.centuryspring.com/ You can search their catalog online by inputting whatever information you have about the spring you are trying to match.
