Swat,

I know your problem. I have used Magnus extensively for years now and here is what I would suggest. I am assuming that you problem occurs when removing an arrow from a target.

First remove the heads from your adapters. Remove all hot glue. Install the insert (without the blade) to your arrow shaft tightly. Mix up a small batch of 12 hour expoxy (not the clear stuff). Scuff up the adapter and the inert of the blade with a gun cleaning brush ( I use a 243 caliber brush).Clean insert and blade with 91% Rubbing Alcohol. Put the expoxy in the inert of the blade. Use enough so you get a little bit coming out around the edges when you install the blade to the adapter. I usually press the blade in on a small piece of soft wood.

Next align the blade on your shaft as desired. Also, very important is to spin check the blade while the expoxy has not hardened, and make adjustments as needed.

Procedure always works for me.

FWIW. I always buy the blades and adapters seperately. I don't like the hot glue that is installed with the screw in blades. I have never had a problem with the larger adapters (about 43 grains) and spin checking the arrows. I have had some problems with the smaller adapters (about 20 grains) and spin checking. I believe the adapters that come with the 100 grain head are extremely small and only fit well with the 100 grain heads. Personally, I use a 145 grain head with a 43 grain adapter. That combo works great for me.

Hope that helps somewhat. It takes a little extra time to do this, but it is fun for me and works great.
