Bitzenburger question

[Gump21Bravo]

just wondering if clamps are interchangeable between bases?

[normf]

Yes

[Forrest Halley]

Yes. However any offset needs to be zeroed out for use with helical clamps.

[ISP 5353]

Yes

[Gump21Bravo]

Thanks guys.

Not if you are talking about the early, ball bearing clamps and bases from the original Bitz's.  

The original base only has a single detent for 3 x 120 whereas the later models have 3 detents.  

The late model clamps attach to the early base but will not place the quill square to the shaft centerline and vice versa.

Cast clamps go with 3 detent and steel clamps go with the single detent.

Not to hijack the thread, but is there a significant difference between the different nock receivers when you're using the helical clamps?  I.E. straight nock receiver with left helical?

[Hobow]

I'm not sure what the difference is but would like to know as well.  

I do right helical, left helical and straight offset all with the standard nock receiver and get good alignment.

[Hobow]

Cat. #1000 Straight Jig & Clamp: includes standard nock receiver and straight clamp; used for straight, and right or left offset fletching. (Recommended for target shooters)

Cat #1002 Right Helical Jig & Clamp: includes right nock receiver and right helical clamp. (Recommended for compound shooters and overdraws)

Cat #1004 Left Helical Jig & Clamp: includes left nock receiver and left helical clamp. (Recommended for compound shooters)

Cat #1006 Straight Jig & R.H. Clamp: includes standard nock receiver and right helical clamp. (Preferred by the traditional shooter)

Cat #1007 Straight Jig & L.H. Clamp: includes standard nock receiver and left helical clamp. (Preferred by the traditional shooter)

I'm guessing that the offset nock receiver rotates the nock a little to the right (or left) to keep the nock centerline aligned with the fletch midpoint to clear the type of rest used on some compound bows that require the fletch to pass through a slot.

If the majority of the fletch were to one side of the shaft centerline like on traditional arrows (rather than equally on the left and right of the centerline) it could not pass through the rest cleanly.

This could also affect the recurve target shooter depending on the type of rest used.

According to their guidelines above, if shooting off of a knuckle, shelf or weather rest, the straight nock reciever is what we should use.

I just went out to look at my Bliz's and clamps-none of the jigs have any of those numbers on them. I have mine marked as to L and R and 4 fletch, but for all I know they coulda' been the wrong ones and none of my arrows are 'Trad'.   :mad:    :mad:    :mad:  
That's like finding out your stainless steel fridge is aluminum!

In a conversation I had with the folks at Bitz any clamp may be used with the standard indexer (jig).Having used all three indexers, the lft. and rt. do indeed reorient the nock (fletch) and this was done primarily for compound shooters. Some vendors still maintain that you must have the same indexer as the clamp. Again the folks at Bitz told me that is not the case. IMHO I don't think for the majority of trad shooters there is a significant difference in performance no matter which you choose to use and that it is a matter of preference.

[Hobow]

Hahaha, CHINESE aluminum at that!

I'd better apologize in advance for all of the future threads arguing over who is more "trad" than whom because of their nock receivers....    

The only place that I have ever seen those numbers is on the box that the jig comes in, identifying the clamp/receiver combination that it was built with.  

Most shops that I've been to only stock the jigs with the straight receiver.   I buy used jigs quite often and have yet to come across one that does not have the straight receiver, even when purchased from the compound guys.
