Have several carbon arrows that the points are rusted and oxidized tight to the alum inserts. Does any one know how I can remove them without destroying the arrow? Denny Sturgis Sr
I heat the tip of the point until the heat is enough to either let the point unscrew or heats the glue on the insert glue enough to pull it out then put in a new one. I now put string wax on all my tip threads to keep them from locking up , hope that helps..

Yup on the string wax. Learned that one shooting the Stainless Steel Bear Razorheads with the aluminum ferrel's. They didn't get along with the aluminum inserts very well and would seize right up. After that I've put string wax on everything.
Need a good penetrating oil, something that cuts rust. I'd be careful of heating up carbon too much.
Try soaking that end in liquid wrench for a day. I've had some success with that.
If the inserts are installed with hot melt, I'd just heat the head enough to pull the insert out of the shaft. After that, you could put the head in a vise, which would keep the head from over heating and heat the insert until it loosens.
Soak them in white vinegar for a day or two,it will take the rust off.
I put a small amount of anti seize on when I assemble them after having the same problems several years ago.
Heat it... A torch has saved me many times...
Thanks for the input. Have tried the heat with no success, will try the penetrating oil. wonder how long should soak the points and will it effect the carbon?
You can try PB blaster
Most penetrating oils shouldn't be a problem. Don't try to force it though. Let the oil do the work.
If you are concerned about the penetrating oil being a petroleum product try WD-40, it's fish oil based.
Go shoot some hard targets, like a semi-rotting stump. I had one stuck the other day and loosened up the point in just a few shots. It was an arrow shot many months or even years before that was lost, but then found. Fletching was gone (fletch tape was still strongly attached), but after shooting it bare shaft into a rotting stump a few times the point loosened right up.
One time at work we had some valves and fittings rusted up pretty good, wouldn't turn with a 24" pipe wrench and cheater pipe. Someone said to use a half motor oil and auto transmission fluid as a penetrating oil. Long story short after about 30 minutes everything broke free with very little trouble. I have used the same trick several time with same results, never on an arrow insert though.
Auto Transmission fluid might be a bit too aggressive for this. Might mess up the carbon. That is a good trick though I've used it before on stuck auto parts.
There is a WD-40 Penetrating oil. I've used it with success on screws that haven't been turned since they were installed 70+ years ago. Should work on you're insert. You could help things along by tapping it between a hammer and an anvil. Not hard. just enough to break up some of the rust.
