glue on adapters for carbon arrows

[Thebear_78]

I'm currently shooting gold tips arrows with 125gr heads and weight tubes.    I have been shooting the magnus stingers but have decided I would like to try a single bevel broad head.  the only problem is there aren't any out there as light as 125gr.    The lightest I have found was the grizzly 115gr.      

I found a tapered glue in adapter for carbon arrows that weighs 20grs.   so doing the math 115+20= 135gr,  pretty much the same as my current setup 11gr adapter and 125gr stinger = 135gr.    Any of you guys used these tapered glue in adapters?     Are they as strong as a standard screw in ferrel?

The glue in/ glue on adapters are likely stronger than a screw in aluminum adapter as the weakest point is eliminated.

Since your also replacing your insert, you gain a little weight because the insert weight is gone, so the insert/adapter you pictured is only adding a net of 9 grains over the screw in point insert if it really weighs 20 grains.  

The little green Grizzly has never impressed me, even my kids have managed to bend them, you'd be better off tweaking your set up to shoot a 125 Grizzly (which would still only be about 135-140 grains with the insert adapter).  There's a really good chance for a mere 15 extra grains on a carbon arrow trad set up you won't even need to tweak your set up at all.

Hope this helps, Tim

I lost an elk on a shoulder hit because the screw-in adapter broke at the base of the threaded portion and the broadhead twisted sideways, splitting the first 1/2" of carbon shaft. I only got blood on the first 1/2" of shaft.  I don't know, but am guessing that I did not hit the bone squarely, causing the aluminum shank to fracture.  It was a bad mistake and it will not happen again.  There is no doubt in my mind that the glue-in/glue-on adapters are far stronger....especially in brass.  If I ever use a screw-in again, it will have a steel shank.....but, I'd have to test that proposition, because the base of the threads would still be the weakest point.   I know, the best solution is to shoot straighter....I plan to do that too!

I agree with Tim about the lighter Grizzlies. I'd not worry too much about matching my field point weight perfectly.....from my experience with CXs,I'd suggest dropping the weight tubes, and going to 125s, or even heavier on the bhd....even to 160 if you have to.  Honest to goodness, when you get them tuned right, it doesn't hurt your trajectory nearly as much as you think it will!  And the 125 Grizzly is a good head, but the 160 is significantly more substantial.

I use the glue-in-glue-on adapters for all of my carbon and aluminum arrows these days. I like them.

I have been using those adapters for carbons sine 2001, aluminums prior to that. I love them. They work extremely well.

You'd be better off going with a steel adapter and ditching the weight tubes.  What do your weight tubes weigh?

Then again, it would change your spine, so that might not be the answer for your current arrows.

Those are stronger than screw ins....


BUT, you can make screw ins stronger by seating them tight and with epoxy.

weight tubes come in around 150gr.    I would have to stiffen up the spine of my arrows quite a bit to add that much weight up front.
