Cutting arrows
 

I recently ordered a dozen Carbon Express Maximas and was wondering what i can use to cut these guys down to size. I really would like to do it myself if possible. Can i use a dremel with a cut off wheel? Also how long is the recommended length for a 29" draw? My current arrows are cut at 29" and they are even with the front of the riser giving me about 2" to the rest. Should i cut them back another 1" to 1.5"?

Another quick question..

Will the difference in the lighter arrow weight increase my speed enough to maintain the same Ke put out? I know that i am currently shooting 220fps and these new arrows are 7.3gr per inch and might be shorter where as my old ones are 8.9gr per inch assuming that the knocks, vaines, inserts are the same weight.



Thanks for the help

Vince, I would leave your arrows at the 29" length. An 1 1/2-2" beyond your rest is fine. You should finish up with an arrow wt. of approx. 355 gr. with a 100 gr. tip. If your original arrows did in fact weigh 463 gr. you will pick up some significant speed and yes I think it will be enough to match or exceed your current KE.

As far as cutting your arrows. If you can have a shop cut them. It's not that you can't use a dremel with an abrasive cut off wheel to cut them it's cutting them square. Unless you have a way to affix your dremel to a board or piece of angle and then rotate your arrow into it like the way true arrow cut off saws work I'm afraid you will not cut them square. I'm assuming you don't have a squaring tool such as one made by g5. You could make a squaring tool by using a fine file affixed in a bench vise and then checking it with a square. Squaring the end you cut is important so if you do decide to proceed go slow.

Do you have a fletching jig?

No i dont have a fletching jig. I guess i will just go to the local shop to have them cut. I want to see how fast they shoot anyways and will need to use their chronograph.

I sure wouldn't cut anymore past the riser. I don't recommend the dremel tool. Most are not fast enough and I highly doubt you will be able to get the end square and highly doubt they will be the same length. I mean most shops only charge like 3 dollars to cut a dozen.

Get ya a decent apple cutting saw.

Take them to a pro shop. They will only charge you about $.50 per arrow to cut them. You would be real upset if you screwed up a $140 set of arrows wouldn't you?

No. You will increase your speed but you will decrease the arrows kinetic energy as well as the arrows momentum.

As you decrease the weight of the arrow the bow becomes less efficient at transferring its stored energy to the arrow. Because the bow transfers less energy to the arrow the arrow stores less energy.

In layman's terms.... this means your bow is going to be louder... noise, string buzz, slap, vibration etc... all of that is just wasted energy... Newton's laws being adhered too.

Tremolo, we will have to wait and see what kind of speeds you get with the CE Maxima's. I'm thinking you'll be in the 250 FPS range and if that's the case you will match your current KE according to BowJackson's KE calculator. Your current setup of a 463 gr. arrow traveling at 220 FPS produces 50 ft. lbs. of KE. After you get your arrows cut and fletched by your local shop hopefully they will allow you to shoot a few through their chrono. Don't forget to have them weigh them too.

My arrows should be here on tuesday so if all goes as planned i will try and have them cut, weight, speed, and sighted in by the end of the day.

Does this saw cut arrows good?

How light is too light when talking about hunting arrows? I find it hard to believe that anything wound not have enough Ke/momentum (stored energy) to be an effective deer hunting setup at 60lbs draw with today's bows and arrow selection.

Not trying to start any arguments here just trying to educate myself here and make sure I have an effective hunting setup. Guess we will see when I have the numbers.

Thanks for the help guys.

I have this saw and it works great with my aluminums and an ASD device.....not sure about carbons though!

Nothing is to light (with bow manuf. minimums) when the shot is executed perfectly and the shot is placed on the animal perfectly. The difference between the heavier/lighter arrows comes into play when shot execution/placement don't go as planned (of course that never happens :wink:). The heavier, slower arrow is much more forgiving of errant shot execution/placement and outside factors such as wind. IMO light and fast is great when you are flatfooted on the ground and using good form to shoot a target but, when you are up in a tree, twisted around, angling down, cross breeze, heart pounding, etc. I'll take my slow and heavy any day.

Got the Idea For the Saw From GGMAT And I am pretty sure he is cutting carnbons with it. It is the Same speed as the Apple saw, so I am guessing good to go, I have not bought it yet, I am waiting for some fundage

The saw works great on carbon shafts . You can easily make an arrow cutting jig ...........

I've been cutting arrows with my dremmel since the advent of carbons, and never had a problem.

Tremelo, I think your current setup with the Carbon Express arrows that weigh out rt at 355 grains will be fine for a whitetail hunting rig. Get the numbers for us and we'll go from there.

Dan

I have used the dremel and it was fine, just hard to keep straight. I bought one of the harbor freight saws and it is fine. It is a little slower than the dremel, but works fine if you take your time. My rig looks a lot like the ones pictured.

tremolo everyone has their own views on arrow weight.I prefer a min of 450grs for any animal.Both for ensuring adequate penetration and being easier on the bow.

Well got the arrows cut and shot at the shop yesterday. Arrows weigh in at 374gr. and shot 250fps. calculated to 52 ft. lbs.
