i ma having a hard time keeping my brass inserts in mt gt's.  i glued them with goat tuff.  i have heard that i need to use hot melt.  what do i need to use to keep them things in and stay?

I have had good luck with the amber colored hot melt.  I also cleaned the inside of the shaft with some alcohol on a  q-tip before gluing.  Only apply the heat to the insert and get the glue warmed up on the insert before inserting into the shaft.  No direct heat (flame) to the shaft.

I used thick gel superglue on mine and seem to be holding very well...Terry

I second cherrybow.

I use JB weld, it works great! Just make sure to clean the inside of the shaft and the insert with alcohol before glueing, have not had one come apart with the JB weld yet.

I use epoxy...after swabbing with alcohol.  I have had broadheads and arrows break, but inserts are still in there, LOL!

Hooked is right on the money.

Some sort of epoxy....I use Araldite

I have used both JB weld and slow cure epoxy, don't use 30 min epoxy it wont hold as well. The key is getting both the insert and the inside of the shaft as clean as possible, your prep work will determine your results.

I use a .270 cal. bronze brush to score the inside of the shaft, then clean with denatured alcohol. I also rough the inserts up with sandpaper and clean. Then I glue them in with JB Weld.

I tried Powerbond, but had several inserts come out in a day of stump shooting.

Cleaning the shaft really helps.  Rough up the inside with some coarse grit sandpaper, then clean out with alcohol.  Also rough up the insert a little.  I have used the epoxy sold for bowyers by 3 Rivers with excellent results.

I second Pickngrin,and it's a lot less trouble to remove.I use a 22 cal cleanig brush for the inside of the shaft,rinse good and it will hold till the cows come home.

Make sure inside of shaft is clean, use Q-Tip and alcohol before gluing insert.
Are the points you are shooting larger in diameter than the shaft? If so, they may be hanging on the target when you pull the shaft out, pulling inserts loose.

I have had great luck with Gorilla glue, apply a thin coat and let dry overnight. Also, make sure that you clean the inside of the shaft and the outside of the insert before glueing, I use Acetone.

Slow set (30-43 minute) epoxy - NOT 5 minute epoxy.

I use Gorilla glue also, but it's very hard to ever remove the inserts, without damaging the shafts.

Sand paper inside of shaft and outside of insert, clean with a cleaning solution then use the longer setting epoxy.  I use the 60 minute and they work fine.  Like Rob said, don't use the 5 or 10 minute epoxy.

i am not wanting to use any epoxy or anything that i can't get out readily.  i was going to use the glue pot i got from 3 rivers and thier glue today, but never got around to it.  
my dad had used gorilla glue on some of his and they are holding well.  i will try the hot melt and then gorilla if all else fails.  maybe i did not clean the shafts good enough--goat tuff will glue the world together.

I have tried just about everything...superglue-works but doesnt seem to hold up for a long time, hot melt- works but not very durable, Bohning (cant remember the name but you got to keep it in the fridge) -works good, JB Weld- excellent, 5 min-2 hour-10 hr-24 hour epoxy- did ok. I am now using some kind of new Elmers premium glue like Gorilla glue- so far so good.

JB kwick weld works great
