Paper Tuning Questions

[canopyboy]

So maybe I'm not good with my search skills, I'm sure the questions have been asked before but I can't quite find everything I'm looking for.

Tried paper tuning this morning on the way into work during a quick stop at the club.  (It's Friday...)

Question 1 - By what distance should the arrow be flying true?  If I step back far enough, the feathers take over and it's wonderful.  I was shooting paper at about 10ft.  Should it be closer?

Question 2 - For a RH shooter, fletching tearing right would mean over spined, right?  I didn't have different points, so I changed the brace height.  Lowering it helped, and I eventually went from a 2" tear at about 6.75" to close to perfect at 5.75".  But I think that's a bit low, I was getting good wrist slap, and I think the specs call for something above 6 or 6.5 (Hoyt Dorado).

Question 3 - So if I'm correct that they're overspined, I have three options that I know of.  The brace height is one (already tried).  Point weight is another (add more).  But don't they adjust a plunger sometimes?  Which would mean I could change the thickness of the strike plate?  Of course being close to center probably means I would only be making things worse.  Or am I smoking crack?

Question 4 - How sensitive are arrows to say 25gr changes in point weight?  I'm at 125 now with a 30" arrow (Beman 500).

I also have a lot of stuff at home in books, but I'm at work and it's eating at my brain.  Any education would be appreciated!

The Elite Arrows website has very good paper tuning instructions. I have found them to be absolutely "dead on" instructions. Click the "proper arrow" tab on the Elite Arrows website.

This is a great resource.

25 grs of point weight can be a lot,as much as 5-7 lbs of spine.

I personally use the planing method rather than paper tuning as form issues when finger shooting can influence results.

I use the tuning information on bowmaker.net.

Yes tearing right is overspined.
I see often to shoot about 7 foot in front of paper.
Make sure you are shooting perfectly "broadside" to the paper. Both left-right and up-down. Otherwise you'll get false readings.

I don't know much about tuning carbon as far as this many grains does what to effective spine.

I know out of my bow cut slightly past center a 43# spine spruce arrow with 125grn tip flies good.

also a 55# spine spruce arrow with 190 grn tip flies good.

Good luck

That site was awesome.  Thanks Jim.
