How do I stop "mushrooming?"

Speaking of Golf clubs, Golf Club epoxy is probably the BEST stuff for glueing in inserts.  My money would be that would fix your problem completely.

I've been thinking about using the 2 part shaft epoxy too.... Holds real tight, and definitely designed to take the impact. Only problem is that it's a 24 hr drying time unless you get the fast set stuff (I never tried it). If you want to remove the insert, just heat a point up and spin it in. Wait a couple seconds while it softens the epoxy and pull it out... don't twist! The only problem is cleaning out old epoxy... If you consider it permanent then no biggie. And the standard  bottle  is big enough to do hundreds of arrows!

Speaking of adding weight and footing a Carbon shaft, has any one used a steel tube rather than aluminum? I have some CX maximas, and CX blacks shafts with aluminum inserts already epoxyed in that I want to add a couple hundred grains too. Looking at weight tubes as well as footing them...

Just foot them with an aluminum shaft of the correct size, as Larry said they are not steel rods, but this will help a real lot. I just footed a binch and my Heritage 150s, I shot into a concrete block at 10 yards, 54# bow at my draw and they held up fine. Shawn

Thats intresting! i will have to experiment with this idea.Using them to also add weight may bethe ticket.

I'd suggest you first clean the inside of the shaft w/ denatured alcohol, then allow dry. Do the same to the inserts. Use JB Weld slow dry epoxy to glue in brass inserts  I've used the bemans and Axis shafts and not had any problem since using JB weld.  

For Axis 340 & 400 I foot the shaft using a 3 inch section of Easton Aluminum 2018 and for the Axis 300 I use the 2117 Aluminum. Clean both glueing surfacinga again w/ denatured alcohol first.  

Mushrooming is occurring due to the insert moving inside the shaft.  JB Weld is the key here.  I know of no finer adhesive for carbons.

I have good luck using amber hot melt on the weighted inserts.I also clean mine and use a 22cal barrel brush for the inside of the shaft.But I'm curios how you get them out with jb weld or do you get them out?

[JOKER]

I too clean mine with a gun cleaning brush, ruff up the insert with sand paper and then use AAE Fastset gel. The inserts will not push back into the arrow, HOWEVER, you will never be able to get them out again.

I've gone to jb weld and it fixed most of my mushrooming problems. However, I don't think you're going to find anything that will fix your problem completely at the distances (very close), with your bow poundage (heavy), at a very hard target (even golf balls are very hard).

[Shawn Leonard]

I did not see ya tried the footing, ya have to position it right and make sure it is longer than the adapter inside. I put it so it is to the back of the insert where it meet the head. Shawn

Honestly, I've never had a carbon shaft mushroom like that. Split like a banana when I hit a steel plate? Yes. But never a mushroom like that from normal wear and tear.

I just footed a bunch of my ICS 400's with 1"pc's. of 2117's for the upcoming Muzzy shoot this weekend.  There's no tougher test of arrows...we'll see how they hold up.....
