Carbon Express Brass Inserts

[mooseman76]

I got a couple CE Heritage shafts for tuning and the brass inserts are impossible to put in them.  I pushed one in with no glue to check the fit and I cannot get it back out.  Then on the shaft I cut, I put a little epoxy on the insert and could only force that one in about half way.  I couldn't get it back out so now it is epoxied halfway in.  What am I missing here?  I've had no problems with the Axis arrows that I used brass inserts in.  Thanks...Mike

if your using the 150,250,or 350 shaft a .244 insert should work fine...if you are using a ce90 it will be too big and youll have to get the custom inserts from john at sipsey river

[mooseman76]

These were 250 and 350 shafts.  I got the arrows and inserts from Sipsey River.  I was wondering if I need to ream the shaft or something before trying to put the inserts in.  Anyone else have them with an extremely tight fit...Mike

Yep! same problem here, they fit my GT 55-75 trads just fine but will not fit my Vapor 4000.

I destroyed two arrows today trying to get them in, I ended up beating on them with a hammer and they blew out the sides of the shaft! Oh well live and learn, all 5/16" shafts aren't created equal.

Take a drill bit just big enough  to fit in the shaft and slide it in the nock side of shaft. Now try to swing the arrow down to the ground and the bit will drive the insert out, sometimes. It can be tricky if they are glued good but I have removed alot this way. I had this problem also had to put the inserts in a drill and take just a tad off so they would go in easier and split the side of my shaft.

I've never had that problem, and I've gone through a few CX Heritage 350s and 100 grain brass inserts. Sorry, I can't help.

Sipsey here...This is the first Ihave heard of this. We sell tons of these things. I have seen some fit  slightly tighter than others, but that is due to some inconsistency in the shaft wall thickness. I have never seen them so tight they will not push in. Are you sure there is not something inside the shaft?
If they are a used shaft, maybe there is some glue residue from old insert. On the ones I have seen that are tight, I just use a shaft cleaning tool to lightly clean the inside of the shaft.
It might be possible we got a bad batch of inserts, but I would think they all have to be the same if cut on milling machines.
I get the inserts from 3Rivers, I will check to see if they have had any complaints or bad bad inserts.
If you want to ream or change anything, I would suggest you put a field point in a drill or drill press. Use  some sand paper to lightly sand the insert as the drill turns it. Better to thin down the insert than weaken the shaft wall.

Yep!

I always use a "carbon prep tool" attached to a cordless drill, and score up the inside of the shaft.  It is surprising how many times I actually knock something off the inside of the shafts.

I also believe that it helps with adhesion of the insert.  Using this and goat tuff, I have never had a brass insert pull out.

[mooseman76]

Nothing inside the shaft.  I've been doing my own shafts up for 20 years now and this is the first time I've had inserts fit so tight.  I have one insert halfway in a new, freshly cut 250 and I have an insert in a new, uncut 350 that is not glued and that I cannot get back out.  Not a big deal, but I'm hesitant to buy these shafts if they fit so tight.  I've had no problems with Axis shafts (well, I had some tuning issues, but nothing with inserts).  Guess this is why I always come back to aluminum.  Thanks for the suggestions...Mike

I too had this problem with cx 250s what I now do is put a field point in insert insert into cordless drill and turn down with a file and sand papper easy to do and necessary for proper fit cannot say why no one else had heard of this problem as I thought it was common for brass inserts to be a little oversized for cx shafts

[JSimon]

I'm with you. I had the exact same problem with CX 250's in the spring. There again, no one else seemed to have had an issue. I ended up chucking up a field tip in a drill as mentioned to turn down the inserts with a piece of sand paper. I had to take quite a bit of material off to get them in. There was a decent amount of dust when I was done. Even then, I debated whether or not to even bother with glue because they weren't coming out. Mine were brass converta point inserts from Kustom King. Said they were good for 5/16" carbon.  Where did you get your inserts from?

[Gordon martiniuk]

I was useing Muzzy 100gr inserts and they are excellent spin true and I have never lost one a eazy fix good luck

I had these problems with some of my first dozen of 150s that were very tight.  Probably you happened to get some that were on the edge of their allowed tolerance.  They are great shafts however, and I've bought a couple dozen since then and not had any problem at all.

If things are a bit tight, I take a round file (a larger version of what I use for filing nocks in a selfbow), and file the inside by hand.  Eventually you will get it to the point that the insert fits right in.
