I' ve been thinking about purchasing the Bitzenburger Dial-O-Fletch. Does anyone know what the degree of helical twist is on a Bitzenberger right helical jig? If the helical twist is too severe and causes clearance problems with my rest, can the Bitzenberger jig be adjusted to reduce the severity of the helical twist? In other words how versatile is the Dial-O-Fletch?

If a straight offset is desired would an additional straight clamp and straight nock receiver be needed? If so can a straight clamp indeed be turned or slanted to produce an offset vane or feather?

The right and left helical clamps on the bitz. are full helicals . you use the the dials on the jig to make the clamp fit flush on different size shafts. If your using a prong type rest i would' nt recomend the helical. I' m shooting right helical with a muzzy zero effect rest (drop away) on easton carbon evolution shafts. You can use a straight clamp and offset the fletch as much as you want with the dials, get a (tm or cock feather style nock receiver) for the straight clamp i use it on right helicals too. the bitzenburger is the best and most adjustable fletcher i' ve used.

So you are saying that the Bitzenburger helical clamp is what it is. There is no adjustment. Whatever the degree of helical twist the clamp is designed for is what you get. There is no way to use the helical jig and still get a less severe helical twist, correct?

However, a straight offset can be easily adjusted by turning the dial, correct? So one could fletch arrows with a very slight offset all the way to a very pronounced offset, all with the same straight clamp and jig, right? What exactly is the additional nock receiver (cock vane down) needed for? I use uni bushings and super nocks and don' t really see an advantage to such an additional nock receiver since I can just turn my nocks to the desired position. Can you explain the advantage of using the cock vane down type receiver?

yooper, that could be true that you could get a decent offset using the straight clamp, however, it will depend on the size of the arrow shaft that you have. For instance, I can get a great offset on my 2613 shafts, but very little on a carbon arrow (same size fletch).

Like others have said, the helical that you get will depend on the shaft, and you wont get that much adjustment on the helical. I can' t even use it on my 2613 shaft because I just won' t fit correctly.

Yooper if your useing super knocks with uni-bushings you can just turn the knock where you want it. the advantage to the cock vane down knock reciever is on a straight clamp it ahlines the cock vane with the center of the knock groove and on a helical clamp it ahlines the center of the vane with the knock groove.But you can turn the knock where you want if you have uni-bushings so it does' nt matter which knock reciever you use.Hope this helps.
