carbon shaft tuning question ?

[tnhornhter1099]

I am trying to fine tune some carbon shafts using different weight tubes inside the shaft, my question centers around the nock or the insert, if you use holt melt glue on the nock and or insert can you then carefully heat the carbon shaft to get tehm back out?  I used to do this often with aluminum shafts but has been afraid to try it with carbon shafts,  anyone got any ideas ?

It is fairly easy to heat the insert and remove it if you are careful not to overheat it.  Screw a good sized point into the insert, like a 145 grain, finger tight.  Apply the flame to the point for about 10 seconds, and then try to pull the insert out by clamping the point in a vise or something.  Repeat the 10 second burns until the insert pulls out.  DO NOT apply any heat directly to the insert or shaft.  If you apply too much heat to the point, you will know it because strands of carbon will pull out with the insert, and that's the end of that shaft unless you can use a short shaft cut off below the burn.

I don't know of any way to get a glued in nock out without ruining the shaft, plus sometimes nocks break and then you have a problem if it is glued in.  You can use a glued in nock insert, if one is available for your shaft, which allows you to replace nocks, but that is difficult to remove also.

Solid advise above.

You can try to snug up the nock fit by adding a strand or 2 of floss in the end of the shaft then sliding in nock, easy to remove. May tighten it up enough until you get tuned and can glue in weight tube to keep it from shifting.

I use bohning blue hot melt for carbons when I'm tuning. I keep a glass of boiled water out and just dip them in to get the inserts out. It works great.

crazy nate is spot on. I use the blue "hot" melt for tuning also. Either that or just put a small dab of superglue gel and remove the insert using the drill bit slide hammer method in the shaft...of course, that wouldn't work with weight tubes and a glued in nock. I'd stick to the low temp blue hot melt.

I will sometimes wrap a nock and the end of the shaft with Scotch tape to keep the nock from popping out. It isn't pretty but is a good non-permanent fix.

What McDave said, except that if you are using hot melt glue, you should never need enough heat to damage the shaft as he described. I hold the point in my torch flame for a few seconds, then grab it with pliers and pull out the insert. Keep a cup of water handy to dip it in after removal to cool it down. It's easy to damage shafts like that if you are trying to get inserts out that were glued in with superglue or epoxy.

I"ve nere tried to remove a nock with heat. Don't know that it would work without damaging the nock. If you crimp the weight tube every few inches, that will help to keep it from moving as much.

One option would be to buy nock inserts and use glue on nocks once you determined exactly what your setup would be.
I know carbon express makes a nock adapter because I've used them on aluminum Game getters.
You wouldnt have to worry about your nocks popping off but you can heat up
the nock insert and remove it if you ever wanted to get the tubes out.

If you've got a soldering iron, heat it up (30W setting) and put it *inside* the insert for ~30 seconds.  Then use a ramrod to kick out the insert.  Works great and doesn't involve putting flame onto the carbon.

Doesn't work for nocks, obviously.

Not a direct answer to your quesrion but i believe it would be better to just use heavier points to add weight to carbons.
