I've seen threads on this before and have, heretofore, believed that removing an insert from an Axis or MFX shaft was undoable, especially if they were epoxied in. I recently received some used Axis arrows in a trade that were 1/2 inch too long. So I simply started to cut that !/2 inch from the nock end of the arrow. However, one of the arrows was unfooted and the shaft was damaged at the point end. It couldn't be used as it was so I tried an experiment...and it worked! I was able to remove the insert without damaging the shaft. I finished the rest of the arrows in the same manner andI took a couple of the redone arrows out for some stumping today. They showed no signs of weakness or damage. Here is what I did.
I had a 2 1/2 inch 8/32 threaded bolt and so I tightened it up in my vise.
Then I screwed the damaged shaft onto the bolt until it was tight enough that I couldn't tighten it any more.
As you can see there was enough room to heat the bolt without getting too close to the shaft.
As I continued to heat the bolt I kept twisting the shaft as if I were tightening the bolt into the insert. After what I would guess to be about a minute I could feel the shaft begin to turn as the epoxy weakened. As I continued to twist I then started to pull the shaft as if I were pulling the insert out...and as it turned out that is exactly what happened. The insert was out. I cut off the 1/2 inch, replaced the insert, footed the shaft and shot it today.
Hope this helps. I am very pleased.
