inserts for grizzlies

[J-dog]

What size insert for grizzly BHds? The ones I have now stick out a bit, not that it will hurt anything, just wondering of they make one that fits more proper.

Thanks Yall,

J

That is normal for Grizzlies on 11/32" adapters.  Grizzlies fit on 21/64 adapters like a glove but they are very hard to find in that size.  We used to have them but can't get them anymore, and the quality wasn't there compared to the Magnus adapters anyway.

I use 2413 aluminum to foot AD Trads. The footing fits over both the shaft and the insert flush to the end. I'll use a Grizzly over a 100grain steel adapter screwed into this footed AD Trad arrow. I do not like the small portion at the base of the adapter that extends from the back of the Grizzly ferule. What I found was that the same 2413 aluminum shafting that I use for footing also perfectly fits over this portion of the adapter that protrudes. I ended up cutting a .160" length of the 2413 aluminum making a small spacer that I glue onto the adapter behind the Grizzly ferule. The outside diameter of this 2413 spacer is just smaller than the ferule and it fills the gap making a smooth and snag free transition to the arrow shaft. I stick it on with hot melt at the same time I hot melt the Grizzly to the adapter.

In the future, I will be searching out someone to manufacture a one piece brass adapter/insert to specificaly fit the Grizzly ferule at the taper while inserting into the AD Trad shaft for a smooth transition to the shaft. This would eliminate the extra joints as well as any gaps or shoulders, and would provide the needed weight to replace the adapter and insert.

I got a better fit after I used a small grinder on my dremil tool to clean out the inside of broadhead.

Good Idea Gil! I think that I will give it a try.

Im a machinist and I turned the 5 degree down about .01" to makem fit,I was thinkin about turning some down to sell...

[Daddy Bear]

Recurve Jim,

I'd be interested in a one piece brass insert/adapter like Muzzy makes but to fit the Grizzly directly to the AD Trad shaft. Not sure if others have given it much thought, but replacing an insert and an adapter with a one piece unit of the same weight would be just the ticket in my book.

Ive seen the muzzy adapters,are you talking about a 5 degree to insert into the grizzly,that glues onto a wood shaft?Im not sure what the AD trad shaft is...

[RecurveJim]

was that arrow dynamics?

[Daddy Bear]

The AD Trad is a carbon shaft which requires an insert to accept a screw in point. I shoot a Grizzly with a screw in adapter to thread into the AD Trad insert. Muzzy makes a one piece brass unit that on one end is the insert that fits into the carbon shaft with the other end having the 5 degree taper to mount the broadhead. The Muzzy unit is for a different shaft and does not fit the AD Trad.

I'd like to see one made to fit the AD Trad with the correct 5 degree taper for proper fit with the Grizzly. This would duplicate the weight of using an adapter and an insert, but would do so in a one piece unit without any gaps, shoulders, or steps. The Grizzly would then fit the AD Trad shaft with more of a seamless connection like you would have on a wood shaft. Simple, strong, and snag free.

Daddy Bear I am thinking the same thing except for the easton axis FMJ made of all steel I was going to see a machinist next week.The weakness seem to come from the threaded and joined sections. A 200 225 grain 1 pc unit would give you the EFOC and no joints or seams.(I'm trying to make a bulletproof arrow Its a personal thing)  Recurve Jim if your looking for a test monkey I would be glad to purchase some and do some testing.

I chuck my steel broadhead adapters in a standard hand drill or drill press, while they are spinning, I use 100 grit sandpaper folded over and gently lay it against the spinning adapter.
Try to maintain the same taper, and it doesn't take much to get them to fit all of the way into the griz. ferrule.
Keep checking often, and only a few seconds at a time with the sandpaper should do it. I just did a half dozen yesterday, took about 15 minute.
When you get done, you'll have plenty of depth in the grooves of the adapter to hold the glue.
I then just clean out the broadhead ferrule with a wire bore brush and then a q-tip with acetone.
I then acetone the adapter and you are good to glue.
I thought about "reaming" out the ferrule to make them fit, but thought it may weaken it.
Hope this helps.

Reaming out the broadhead in my opinion would be a mistake.I had to turn over .01 an change the angle of the ferrule.I guess you may have gotten different screw in ferrules than me,but if I reamed my grizzly heads out so the ferrule fit the wall thickness would have been around .005 on the head and to me thats not good,not to mention the heat from grinding that much off,youd need to dunk it in water or risk weakening the temper.Ill try to get a cut off from an ad arrow so I can get the i.d. an o.d. and see about machining some of those heads.
