(Question)
How is the arc adjusted? By a wrench or a handle?
(Answer)
The Crown Arc Uses A Crank Handle to push/pull the tube.
With
each pass you use a socket or racket wrench to tighten the center bolt
increasing the amount of arc produced.

(Answer)
On small to medium sizes boats you can
use 6" to 8"radius. (7/8" Tubing) On larger Boats 10" & 12" Radius

(Question) We are arcing 7/8” tubing with a crown arc bender. When we pass the tubing through it arcs properly but we are also getting a bow in the frame. Why is this or what could be causing this?

Otherwise you will get a bow in the tube.
Use wooden blocks to support the tube on both side of the crown
