I never will understand permanently gluing in inserts in a product that can't be heated hot enough to remove them. Seems rather nonlogical doesn't it? If you get them out, get you some low temp hot melt to use....and they will stay in if put in correctly...even shooting foam.
If you look closely as he’s pulling the last point at about the 2:12 time frame the insert looks very dark/ blacked to me. I would guess it was hot melt and that darkness was caused from smoke when heating the hot melt for installation. But that is just a guess on my part.
Usually if I don’t get an answer that means either they don’t know or want to share info. Of course they or any one who sells their shafts would rather you buy another dozen. Never tried the drill bit trick, seems to me if the glue lets go with that motion it wouldn’t keep the insert in that well anyway. I am referring to the arrow impacting the target over many shots. I wouldn’t count misses that may mean hitting hard objects.
I will admit I was a “low melt” sceptic but after a year of constant use and that means bouncing arrows all over the desert floor I haven’t lost an insert. I am somewhat anal about shaft prep and insert cleaning which I have always done no matter the shaft material or insert type.
I insert a target point and heat that, transferring the heat to the insert and then use a rifle cleaning rod to tap on the insert from the nock end. Most give up the ghost and release. There are some that do seem impossible.
X3 on the drill bit. Just did it a couple of weeks ago. Word of caution: Bit and insert become projectile when the adhesive finally gives way completely.
The drill bit work sometime and sometimes not. I have only used hot melt on Carbon, wood, aluminum and fiberglass. I have talked to a couple people who epoxied them in and the tip grip stuff who tried the drill bit trick and end up pulling the inside of the shaft apart. As George said above, why not use hot melt?
I have used the drill bit trick on epoxied-in inserts but I had to heat the point first. They do become a projectile when they come out. I was thinking of inserting the proper size screw into the insert and tieing a length of string to it to keep it from flying around the room. Even putting a soft towel on the floor doesn't tame them.
The drill bit method has worked for me but never on the first swing. I made a “catchers mitt” from surgical tubing to catch the insert and drill when all hell breaks loose. Otherwise, you could “knock an eye out”. Or break a window. Or loose an insert and drill bit. LOL
