Our Fletching Jig makes a good looking fletcher, made from steel, although it doesn't have the weighty feel of a Bitzenburger it does have some mounting holes in the base which allow it to be mounted to a solid surface or board.
It has the standard nock receiver adjuster which will enable both 3 and 4 fletching, The one nearest the nock slot is for 3 fletch fletching, just screw it down flush and raise the other one to halfway.
For four fletches just screw down the one at the further end and unscrew halfway the near one - it sounds complicated but it's simple in essence. The jig also has an adjuster on the clamp which allows some adjustment in the tension or gripping power of the clamp.
One of the really great features of the clamp is the graduated scale very clearly stamped along the side - it won't wear off or become unstuck, it is permanent and very obvious.
The magnet operates positively and the jig is easy to use, there is a certain amount of adjustment for offset but no helical option.
