Right or left helical ?

PRB · Post by **PRB** » Mon Apr 03, 2006 7:19 pm

If you wanted a bolt/arrow to turn clockwise after it leaves the bow so that it will tighten the insert against the head upon impact instead of loosening it then is it right or left helical to be used ?
I have mine turning the correct way from using the straight clamp at an angle but dont know what I have to correctly call it

and was wondering what true helical is used to accomplish the same thing...left or right ?

I was just wondering which way you look down the bolt to tell if it is a right
helical?

Ya don't

you read the clamp

From looking at my jig, the fletching /vane would be twisted from back towards the front/tip of bolt or arrow clock wise.

Gentlemen,
I'm kind of new at this, so please indulge me. Why would one put helical fletching on a crossbow bolt? Wouldn't this have a tendency to slow the bolt down? I seem to recall that traditional helical fletching was/is used to provide a more forgiving arrow to recover from "paradox" off the shelf/rest? What would be the advantage on a crossbow bolt? Please feel free to enlighten me.

Regards
Joe

GaryL, if I look down the arrow or bolt from the nock towards the tip the
vane should twist clockwise for the shaft will tighten up on the brodehead on
iimpact? Just to clear things up for me thanks!

Im not sure if anyone uses helical on theyre bolts or not. I have a straight clamp. I really should have asked in reference to right or left hand offset and/or degrees.
Does anyone out there use helical ?

Ayep thats correct hikerman.

pokeynojoe I do not know of any that use a TRUE helical fletching on a xbow, however that being stated one could, as long as you did not put too much twist (helical) on the feather as to rub the rail. With feathers I have been told one can go 4deg. helical but have not tried that.
