ok how do you folks determine your radius's for a preselected arch,,
example need a arch that is 13.375 long and 1.75 high.. i am sure there is a formula to do it out there but this old noggen has forgotten it and the string trick is getting old.. help also need the radius for a 15.375 arch as well
