whisker biscuit and center shot?

[liquidorange]

what is the correct way to set up the biscuit and arrow knock. should i find dead center of the string by measuring the string and cutting it in half then setting up the whisker biscuit ? i always thought you had to have the knocking point a little high but my local pro shop says if your shooting a caliper release to have your knocking point dead center. also on my bow there are screw in type burger button holes on the rest i think?. in setting my bow up should my arrows and rest be set up so the arrow is level with these holes or should i go by dead center of my string and not worry about the holes lining up.

I' m no expert, but incase your wantng some sort of answer today-
Do not ignore the burger holes. Set up your arrow so it cuts through them dead center and then is perpindicular to the string. (for starters)

A tip I saw on Arhers Choice went like this.
Set your bow up to somehow be held vertically (they used a fancy bow holder, I imagined jamming the lower limb into a couch cushion and then leveling the string w/ the front of the riser gracing the couch back cushions)
and the use a level on the string until it' s pefrectly level (perpindicular to the floor).
Then place an arrow on the string and use a level on it to find the nock point.
When the bubble reads true, mark it and then place your nock/ loop.

I think a lot of confusion is created with the word " nocking point" , some people refer to the location of the brass nock pinched onto the string. Some refer to the arrows nock on the string.
I don' t think this was an issue before the string loop became so popular. (I could be wrong as I have been before)

Now the words " center shot" refers to the amount the rest is away from the riser.
You can eyeball it for starters. put an arrow on the string and hold the bow from behind. Line up the arrow with the string and the string with the upper and lower portions of the riser. at least that' s how I do it before fine tuning.

Did this bow shop not set up your bow for you? or was this over the phone advice?

the shop set my bow up while i watched but my arrow is not in line with the holes mentioned. is it safe to say those holes are dead center of the bow? i was using a ultra knock( i call it a horseshoe) but switched to a string loop because the guy at the shop said the ultr knock could be a cause for not so tite groups which is the reason i brought it in. i never had real tight groups probably average.i wanted to learn myself so thats why im asking everybody i can on proper set up of the rest and knocking point. the other thing i need to know is how to set the knock. i was always told to set the knocking point so my arrows are 1/8 to 1/4 inch high but this pro shop guy swears it should be level with a release. also im looking for an opinion on a peep site. im using a rifle type site called erradicator. do you think if i add a large peep to my string to it making it a 3 point sighting system accuracy will improve? sounds like im gonna have to try everything just out of curiousity

If your wanting to learn for yourself, a good place to start is with the Easton arrow tuning Guide. If you go to eastons websight it will have a link for a downloadable version of their guide. It covers most everything and is a great place to start.

Dead center sounds like a good place to start. But you need to tune from there and yes you may need to raise your nocking point, but only as a result of what your arrow needs (tune with the arrow your gonna shoot).

Liquidorange: There is more than one way to tune a bow. This is how I do it. The first thing to do is to verify that you are using the correct spine arrows for the bow. Too light of a spine arrow and it will bend and flex as it goes through the rest and thats not good. With the whisker biscuit you want a loose biscuit to arrow fit, a tight biscuit is not good. I usually start by setting the bow at an even tiller. I just back off both limbs three full even turns from max and that is close enough to work. Bolt the biscuit on the bow. The biscuit shold be parallel to the bowstring, not tipped forward or backward. Nock an arrow on the string at a 90degree angle to the bowstring and place a single nockset above the arrow. Adjust the windage for the rest by grouptuning for the narrowest group. On most righthanded bows the nocktravel is forward and to the left about 1/8" or so on account of the cableguard stressing the right side of the bow, so adjusting the rest about 1/8" left of center will probably have the bow shooting its straightest and narrowest group. Leave the arrow nocked at a 90degree angle to the bowstring and adjust the tiller if needed to get a level arrow in the target. If the arrow is hitting nock high the upper limb is doing more work than the lower limb so you would tighten the lower limb bolt to correct the tiller. If the arrow is hitting nock low the lower limb is doing more work than the upper so you would tighten the upper limb bolt to correct the tiller. You don' t need to be adjusting the nockset on the bowstring to get level arrow flight with the whisker biscuit when this can be accomplished by correcting the tiller. A properly tuned bow and rest shooting the correct spined arrows will usually put both fieldpoints and broadheads in the same hole. Liquidorange, good luck tuning your bow. I hope this sated your curiosity a bit. Good luck hunting!

thanks for the info and now for some more questions? im shooting gold tip carbons in the correct weight range and are cut to stick through the biscuit with an inch overhang so im assuming spine is good. i set things up to the best of my ability and have my bow shooting much better. i went back to my ultra knock instead of the rope loop (dont see any difference) how do you figure out how to set the biscuit the 1/8 inch to the left as i am righty? is there a tool or gauge or is this a set up by eyeing it up? also i have trimmed the back side of my biscuit as discussed on this forum and opened the ring up just a hair so the arrow is not snug or too loose.
