The Cauldron Jig is a 3 vane advanced fletching system.  It provides the right amount of pressure for excellent adhesion, and you can fletch all three vanes at once so it's a big time-saver.  The snap-in inserts are easy to change and don't require tools, so you can switch from a three degree right helical to a one degree right in no time.  With this jig you can leave the nock on your arrow so you don't need to change the center post - simply twist the dial at the bottom of the jig to rotate your arrow for perfect indexing. The Cauldron can fletch plastic vanes up to 5" length. The Cauldron pressure ring is adjustable with a single twist to accommodate micro, standard, and large arrow diameters.  Cleaning is easy: the inserts can be soaked in acetone for an hour to remove instant glue residue.

The Complete Cauldron includes inserts for Straight (gray), 3° right helical (black), 3° left helical (purple), 1° right offset (red), and 1° left offset (orange). 

The Helix Cauldron includes inserts for 3° right helical and 3° left helical.

All inserts are also available for purchase separately. 

The Cauldron Jig is entirely manufactured, assembled, and shipped from the Bohning factory in Lake City, Michigan. Proudly Made in the USA.
