You can hangup the straight jacket

[Troy Breeding]

#6031

Nope,, no one will need to locate a straight jacket for me. I finally broke the barrier and now have the golden tipped “HAMMER” in my hand.:D

Thats right boys and girls I’m setting here looking at a finished arrow that flys like a rocket and has a UEFOC of 40.38855%.:shock:

To some the final weight (992grs) may seem a bit high, but once you see it fly I doubt you would even consider it a problem at an average hunting distance of 20yds or less.

Of course, I approve of the name of this new arrow.

And it sounds like if you ever break a string or snap a limb, you can just throw the arrow at your quarry.

The biggest laugh I had today was while doing the test shooting at the local wheelie shop. One fellow walks into the shooting lanes to watch. When I turn the shot loose he replys “sure wish my bow was that quite”.

:D:D:D if he only knew what we know.

Congrats on making 40%+ and good flight!

Scout,

I’m using a 55#@29″ recurve I built. I wanted to shoot the arrow thru the chrony while at the shop yesterday, but it was on the blitz. I’m interested in knowing what kind of mominium I’m getting.

Been thinking for afew hours now and finally desided on the final name for the arrow.

I’m going to call it the “AIRHAMMER”

I found a use for the new “AIRHAMMER” arrow. It might be a big help with this little fellows wake up call.:D

Troy,

Where do you get a tip of that weight?

[james gilmer]

#47718

what materials did you use to achieve that weight and efoc?

[Raymond Coffman]

#47730

Troy —

I am curious also at the speed—

what broadhead / field point combo are you using?

Scout

[Troy Breeding]

#47732

The point is a makeup of a 275gr steel point adpt. (that I made out of a 300gr screw-in fieldpoint) and one of Joe Furlongs 300gr brass fieldpoints. Total weight 575grs.

The shaft is a Victory VForce HV 300 shaft, carbon internial footing, 100gr brass insert, and aluminium externial footing. I fletched the shaft with three 1.5″ A&A feathers and the nock is a std. Easton Supernock.

Total weight of shaft, shaft add on’s and point is 992grs.

I’ll use the same weight adpt and one of Joe’s 300gr broadheads to make the same weight BH for hunting.

If I can swing a hog hunt this spring I will be carrying atleast one of these arrows. I’d love to see what it would do on a nasty ol’ thick shielded boar.

Troy —

I use the 225TH now, saw that Joe had come out with a 300gr —

Have not had a chance to purchase/workup any Hunting arrows with it.

Have you shot “AirHammer” enuff yet at varying distances to note If? when the drop becomes significant? ie – need to get closer than 20+- yards ————

Scout

[Troy Breeding]

#47771

Havn’t been able to shoot past 20yds. Thats the length of the local shops range. I couldn’t see much difference in my gap between 5-20yds indoors. It’s been so windy around here latly trying to do tuning outdors is almost out of the question.

Just guessing, but I’d think anything beyond 25yds will show a big drop. Thats due to the overall weight of the arrow.

I can say that this arrow flies as flat as my 700gr 33.46% FOC arrows at 20yds. I had two fellow recurve shooters watch the arrows from the side to see which seem to be flater in flight. They stated that they thought the 40% arrow might have even been a tad bit flatter.

Troy —

Very interesting —-

The old saw — “heavier arrows use more of the bows power” [ or words to that effect -haha]

seems to be occurring–cool –at least at Tradbow range

I like as much penetration as I can get.

Troy,congratulations! You said you were going to do it,and you did.It is amazing what purpose and conviction will accomplish.Will you have the AIRHAMMER at Kazoo?

You can bet I will. Ed would skin me alive if I didn’t bring it with me.

Scout,

Finally got a calm day to do some backyard testing. I checked the drop in the 40% arrow as well as my hunting 33% arrows.

This is the 40% arrow at 10yds.

Here is the 33% at 10yds.

40% at 15yds

33% at 15yds

As you can see not much difference. I’ll make another post with other distance.

I can tell I’m gonna have to get off my butt and practice alittle more. My groups and left and right are lapsing.

Troy

[Troy Breeding]

#50069

Here is the 40% at 20yds.

33% at 20yds.

40% at 25yds.

33% at 25yds.

40% at 30yds.

33% at 30yds.

I tried my best to hold the same gap on each distance. Even though my gap is different for the 40% to the 33% arrow I still tried to hold the same gap with the same arrow at different distance.

As you can see bothe the 40% and 33% had little to no change in impact out to 20yds. Yet both arrows started to drop at 25yds and dropped even more at 30yds.

Troy

#50108

Troy —

Thanks — Very interesting ! I am shooting a 31 % arrow and my drop at Yardages shown is similiar to your 33% [and 40% apparently]. I found my PBR { point blank range – at my avg accuracy level} to be just under 25yds [22 for small WT]56 -60lb Bows.

You need to get a Big Pig now! — head to TX! haha

Scout

[Troy Breeding]

#50114

Scout,

If I can swing it this spring I plan to see what the “Airhammer” will do.

I also did alittle speed testing with my own chrony afew minutes ago.

The 992gr arrow shot 136FPS average at my 29″ draw from my 55@29″ recurve.

I also tested a 803gr 31% arrow that went an average 148FPS.

Along with those arrows I tested my 700gr 33% hunting arrows and they averaged 159FPS.

Now I have to look up Ed’s notes so I can figure my mominium of each arrow.

Troy

[Raymond Coffman]

#50151

Troy –

I have My own Chrono also. My 31% arrow [730gr]is running 159fps out of a 56lb@27″draw shrew. What interests me is that at Tradbow Yardages[-25yds]that widespread of FPS,and what a lot of people would consider slow does not effect [Practical]Traj and you have a lot of momentum in the “Airhammer”!

Scout

[Troy Breeding]

#50233

Scout,

I was alittle surprised when I got those low speed numbers with my recurve. I’ve got a three piece longbow of the same weight that I made that had better speed.

If I did my figures right my 700gr arrows has .494 slug ft

The 803gr arrow has .527 and the 992gr arrow has .599 slug ft

Troy

[Raymond Coffman]

#50256

Troy –

Yeehaa – .599 slug ft! The “Airhammer” would make short work of “Hogzilla”. Will be looking forward to a “Field Report”

Troy if you visit http://tuffhead.com/education/formulas_momentum.html

there is a calculator to figure momentum .It makes life easy:D

Troy just received a email from Dr Ashby informing me that the calculator is not correct…..It is right now……He did not mentioned your name but I figure there are not many that could see or have the interest to tell it was not correct.If you caught it Thanks! If it was some one else Thanks to you.

Any way all is good:D http://tuffhead.com/education/formulas_momentum.html

Yep, it was me. While posting back and forth with Ed I told him about the difference in the decimal point. He said he would contact you about it.

Hi Joe,

A question about your momentum chart. I have not chronographed my arrow, so I just wild guessed at a speed, 150, and entered my arrow weight 560g, and got .373. So what does that mean?? Is that somewhere in an Ashby report?

Thanks for the calculator. They really help.

Troy,

Someday they’ll make a honeycomb shaft with a smooth skin filled with helium to help you get up to about 75%. We’ll really hear the cork pop then!

dwc

[codger]

#53190

with that arrow weight the penetration should be insane! what are you going to hunt with those?

[Troy Breeding]

#53399

Codjer,

Since the deer around here must think it’s taboo to come around I guess I’ll have to use them on the ground moles this spring. The moles are making a wreak out of my yard. I stomp down their runs and can watch them hump back up as they make their way around the yard opening them back up. I’ve set traps, I even put out posion.:evil:

I figure all I have to do is stomp down a run and wait for it to start humping back up. When it does I can ease close to it and shoot just in front of the hump. With that much weight and momentum I should be able to get good penetration into the ground and hopefully thur afew of those little scutters.:D

Troy great work ….it looks like you dont have a turb ring on the 40% arrow Thanks Shane

#60366

At the time of posting the pics I hadn’t put the turbo band on yet. Since then I have put one on. It was flying pretty darn good and now it seems to fly better.

Troy

[Crystalshrimp]

#60619

I noticed only 3 feathers. Do you have a helical on them?

[Troy Breeding]

#60995

Leo,

My fletcher is a helical fletcher, but with such short feathers there is very little helical to them.

I been ask by others about three feathers vs four. I look at it as I don’t want anymore weight on the tail of the shaft than I have to. Besided, if three will handle the arrow then why add more.

Even with the minor weight of the three feathers my FOC was reduced by over 1%. It’s really amazing how such a small amout of weight can change your FOC when you get close to or exceed 40%.

David,Yes Dr Ed explains this in one of his articles you can find it at http://tuffhead.com/ashby_pdfs/ashby%20ours/PDF%20Momentum,%20Kinetic%20Energy%20and%20Arrow%20Penetration.pdf.

Momentum is concept that is hard to understand. The two variables are mass and speed. The heavier the object the more momentum it has. Momentum is why the driver of a car applies the brake to stop the car rather than just taking his foot off the accelerator. The car has gathered momentum and will continue to move forward after the driver stops accelerating it. The greater the mass of the object, the more the momentum. It is harder to stop a large tractor trailer than it is a small compact car. Freight trains take much longer to stop than a short passenger train.

The measurement of momentum is the slug. A slug is equivalent to 32lb ft/sec . The higher the value in the formula means your arrow has more momentum than a arrow with less slugs. This is an over simplification.

Hey Troy,

If we can’t use the straight jacket, can we use shock therapy 😯 lol good job really.

I see you use a gap system, what is your point on?

I’m guessing around 20-25 yards for split fingers and a lot less if your 3 under.

Just curious.

[Troy Breeding]

#17973

David,

Point on with the “Airhammer” is a tad over 30yds.

Two word on shock therapy,,,,, H*!! NO!!! can’t stand electricity… Thats the only thing I consider worse than being attacked by a grizzly…:D

Got back from K’Zoo yesterday and I wish all of you could have seen Ed’s face when he held the “Airhammer” in his hands.

I’ve seen some happy faces on him, but when he held that arrow it was like someone had given him a million dollars.
