Aluminum footings on carbon arrows?

[Chumster]

Ok, I have searched, read, watched all the how to's on footing carbon shafts for use as stumpers. Can't figure out if the footings are:
1) Glued even with the existing insert?
2) Insert glued into aluminum footing?

I'll pick door number one.

Slide the footing onto the carbon shaft prior to installing insert. Glue insert into the carbon shaft. Put some glue on the outside of the carbon shaft where the footing is going to sit and push the footing flush with the back of the insert. I also beveled the edges on the footing and deburred the insides before sliding them onto the carbons.

Yep, what Fred said. If you choose the correct size aluminum footing it should just barely have enough room to slide onto the carbon shaft, then the insert will stop it from sliding off. If your inserts are already glued in, not to worry. Just take the nock out, strip the fletching off and slide it on from that end, and I use super glue around the end of the shaft where the aluminum footing will sit. Just be careful not to get any inside the threaded insert, or you'll have a heck of a mess on your hands.
Forgot to specify, the insert is glued into the carbon shaft and not the aluminum footing, the footing slides down on top of the insert and that's where you want it to stay.

Most carbons I use 2117 alum arrow pieces Glued with epoxy over end of arrow flush with end of carbon arrow makes them bomb proof.. Favorite epoxy is plane old JB weld

OK,,, now I'm going to sound like a big dummy.

What the heck is all this supposed to do????

Thanks for the help and pics. Very clear now! From what I understand the 2117's should work well on my GT 3555's.

Troy, When a carbon shaft breaks its usually right behind the head. Footing it stops the carbon shaft from splintering right behind the head when stumping if you hit a rock or other hard object.

Fred,

Now it makes since. Most of the damage I had to carbons has been from hitting something hard and splintering the end of the shaft when the insert gets shoved in.

Until now I thought it was just a way of making carbons easier to pull out of targets.

This should also help with breaking shafts behind the insert when the broadhead fails and shows in some of Dr. Ashby's reports.

Anyone ever tried this on MFX Classics?

Chumster, I shoot GT traditionals 3555 and the 2117's are what I use.

Troy, Never shot MFX Classics but I'm sure it will work with all carbons provided you use the correct sized footing.

That's what those in my pic are, and footed with 2117 shafting. A piece that's 2.5" long will weigh right at 26gr. and I was shooting for 25gr. so it came out real close and fairly easy to get them all within +/- 1gr. of each other.

[Chumster]

Semo, I was thinking 1 - 1.5" pieces, would that be enough length? Not worried about the gr. at this point. These are stumpers first.

Chumster, the ones on my arrows are just shy of 1 1/4" and weight 12gr. They do not effect arrow flight.

[SEMO_HUNTER]

You can make them whatever length you want to. I actually needed about 25gr. more weight up front to get the spine where I wanted it, so that's why I cut mine at 2 1/2" long.

[Chumster]

Thanks 1/4 away, you've been a great help.

The issue with long footings is it changes the spine and the extra weight is not predictable as far as the increased weight does not offset the increase in spine.

I think that's pretty much a non issue when your talking about a 32" arrow full length for a 28" draw. If I had them cut down to 29-30" then yes it could be an issue, but the extra 25gr. up front from the footing did do exactly what I wanted it to and the arrows fly like darts.

[PaddyMac]

Yeah. I footed some 5575's with 1-1/4" 2216s thinking it would limber them up a little and it did exactly the opposite.

Now I have 18 or so chamfered 2216 footings waiting patiently in my tackle box.
