Tuning a whisker biscuit?

[ND Smith]

Hello all, I'm new to this website.

I recently purchased a Hoyt Vectrix. I shoot it at 70# and 28" draw. My arrows are Goldtip 5575s and a 90 grain tip. I also installed a whisker biscuit. I am having trouble paper tuning it. No matter what I do, it keeps giving me a 1" high nock tear. Any suggestions on how to improve this?

Thanks!

I had the same problem but the guys here helped me out really well.
Is this your first bow, have you shot a bow before, is your drawlength correct......some of the questions they'll ask you in order to get the problem fixed....
I'm no pro but I think you might want to shoot heavier tips on those arrows.
do your arrows have enough clearance going through the whiskers, the arrow should only be touching the black whiskers underneath.
And is your nockingpoint in the right position ?

Was it installed by a pro shop, or did you do the install yourself? When these rests are installed correctly they usually work very well. Sometimes need a little fine tuning. Normally, adjusting the height so the center of the arrow is running right down the center of the Berger button; and setting the left-right so the center of the arrow is about .800 from the shelf is a good place to start. Once the height is set, adjust your nocking point to be about 3/16" to 1/4" above the point on the string where the arrow is square with the string.

I'm looking at your arrows. Gold Tips are notorious for being underspined. Try this for a check. Turn the bow weight down about two turns and see what happens. Try tuning the bow this way. If it's better then I'd suggest that you have an arrow spine issue. Then you'll have a choice of shooting it at less poundage (not a bad choice) or getting stiffer arrows.

By the way, I always suggest this because it's a free way to check things.

I agree with BGfisher, the spine is likely quite weak. You should also make sure the hole in the biscuit is much larger than the shaft diameter. If you do this and are getting a tear, then it's likely due to form, tuning or spine issues.

I had the exact same problem with a whisker biscuit set-up. I had a 0.5-.75 inch tail high tear that I could not eliminate. I spent days shooting through reams of paper.

I had to move the biscuit in the opposite direction of 'normal' as defined by the Easton Tuning Guide. The Easton TuningGuide mentions this remedy in small footnote that I had not noticed previously.

Here's the paragraph:
[align=left]For archers using release aids, it may, in some cases, be[/align][align=left]necessary to apply adjustments opposite from those[/align][align=left]described. The type of arrow rest and release aid[/align][align=left]combination used can alter the dynamic flex of the arrow[/align][align=left]to produce tear patterns contrary to those indicated[/align][align=left](although it is uncommon).[/align]
This is the tear that I had. Imoved the biscuit down - worked instantly.
