Too light of arrows

[tecum-tha]

You take one shaft, go to Menards, Home Depot or Lowes and check for Poly or braided nylon cord that fits snuggly into the shaft(pull nock out, most 1/4" work with 5/16" carbons).
Take a grain scale and weigh 1 inch of cord.
Then determine length needed to get to the weight you want. If the length is less (about 2/3" of the shaft length or so), then heat your field point and pull insert out as soon as you can pull it. Heat, try to pull, heat some more, etc. you get the picture. Pull out nock. Clean broken down glue from inserts, pull a long piece of serving thread through the shaft. make a loop and pull cord through shaft until about a little bit before it would hit the insert (just measure insert lenghts and a little bit).Pull serving thread through insert, put 2P-Epoxy on insert and a dab of it on end of insert. Push insert all the way in. Pull on serving thread to seat cord on back of insert. Take sharp knife, cut serving thread in insert as far down as you can and screw in a field point with waxed threads.
Let epoxy harden with nockside down. You now permanently fixed the cord to back of insert and if you do 1/3 or 2/3 you gained more FOC.
Cost: $1 Dollar Store 5 min Epoxy
$7 cord to do at least 18 arrows (50 ft)
Weight tubes cost money and change spine. Cord is cheap and does not change spine.

Hey Mr. Wessel do you glue the weedwacker line into the shaft?

[talltines]

No.  I put the line in and cut it so that it will allow the nock to go back in the shaft.  Btw, stop the Mr. stuff. : )

I think you are fine at your arrow weight. Especially for whitetails and other light North American Big game. The only time you would need to up your arrow weight is for something like a moose and the like.

500 grains is perfect. I have killed 5 deer the last 2 years with 500 grain arrows out of a 50 pound bow. One was at 25 yards...the buck in my avatar. Blew right threw.

If you want more weight add it on the point and dont worry about going up in spine. Carbon shafts are stiffer and can handle more than people think. When Muzzy was developing the brass inserts for carbon arrows I was involved in the prototype testing and I loaded up to 400 grains to the front of an arrow without any change in flight except for the drop.

Didn't read all the posts, but I would switch to the GT5575 trad next time you get arrows.  Low price, heavier, and way more durable.

To use what you have maybe build out your side plate a little and go up to 100gr. inserts.  That will get you a little more weight without a change to broadheads.  You can do the same thing by adding larger or second set of silencers.  That will take off some efficiency so stiffen your arrow a little more plus quiet your bow more.  Then you get quieter bow and can up your insert a little more in weight.

I have not seen where weight tubes are that great.  Weed whacker string was okay if bent some to keep it somewhat quiet.  Rope settled on me and shot lousy.  

If you can cut your arrows more and add another 25 gr. in insert and point weights do it.   I don't like the larger than 175 field points much, but I love heavy broadheads now although I do really like the 175 VPA and try and tune to it when I can.

I see no real problem with what you have now.

[Iowabowhunter]

I am going to try the weedwacker line as I just can't justify getting new arrows, and I have a doz VPA 175 grain heads that I can't afford to replace. If not then the weight tubes will be up next

[VictoryHunter]

I personally wouldn't go any heavier. As they are you should be just under 10gpp which will give you the best combo of speed and KE.

[Iowabowhunter]

I'm not worried about speed, quiet kills. I draw 29" which makes a 57# bow, with 500-505 grain arrows they are pretty quick but I want them quieter. I got out of the compound thing because all anbody cares about is speed, I'm shooting fast enough as it is, I want a heavier arrow to help with sound dampening and a harder hitting arrow. I want to be as close as possible so speed doesn't matter a rip to me anyways.
