Good Dividers for the Crucible Engraving Tool

Several readers have asked for recommendations for a budget-priced wing divider that will hold the Crucible Engraving Tool. My first choice is to get the Starrett 6" carpenter’s divider (either used or new) or one of the many equivalent vintage compasses available on eBay.

But if you want to buy new, and you don’t want to pay for a Starrett, I have only one recommendation: The C.S. Osborne 104-6 extension dividers.
