this is the kind of form I have always used,stole it from my mentor, gary davis, the front is cut out to the amount of reflex you want, then screwed to a 2x6 this allows you to reflex and straighten at the same time, I have different amounts of reflex, and some that are wider for real crooked staves, some that are cut on a angle to take limb twist out, could not make bows without this tool
