xcaliber, I have a package of the 100's that I will test this weekend. When assembling them there is the main ring that goes on after you load the blades and then there is the 'O' ring. After the 'O' ring there is a nother very thin ring with a large bevel on it which seems optional. Do you know wha...

xcaliber,

I am checking out the 85 grain Thunderheads as they have a nice short profile which looks to be very aerodynamic. I am thinking with a 110 grain front insert they may fly real nice. Have you ever tried this combination?

Thanks for the feedback!

I have a question regarding 100 grain Thunderhead Broadheads. I have never understood what the purpose of the 'O' ring is but when I tighten the broadhead down onto the bolt the O-ring really compresses and squeeze's out beyond the diameter of the bolt.

is this normal or is this a concern?

Thanks Don,

I used the calculator and based on the results they are using the formula that includes the broadhead in the overall length calculation of the arrow which is what makes the mold sense.

My FOC is coming out at just over 20%

I have noticed two different formulas online that are used for calculating FOC. One includes the broadhead in the overall arrow length measurement and the other excludes the broadhead from this measurement. The difference between the two is roughly 5%. What one of these two formulas is most commonly...

Yes, I made a few extra bolts so I could do a destructive test on the adhesion and it was exceptional. Even with pliers I could not pull the vanes off.

MeatEater with Steven Rinella, the Western Hunter with Nate Simmons, Solo Hunter with Remi Warren and shows with Randy Newberg. All these shows depict real hunting on public land.

I would like to thank everybody who provided feedback regarding best fletching methods. I finished up my bolts and am very pleased with the results. I used Zombie Slayer shafts, removed the decals, Bohning Insert Iron for the front inserts and Goat Tuff CA adhesive for the Bohning Blazers. I used th...

Will temperature change my POI?

If I am shooting dead on at 40 yards on a June day with 70 degree temperatures can I assume my POI at 40 yards will be the same if it is 28 degrees in November?

Is there a solid mount available for mounting a Go-Pro camera to an Excalibur crossbow?

When building ones own bolts is it truly important to spine index them or is this mostly hype? If truly important how are you performing this task of spine indexing? Is there a jig or tool that is used?


Thanks,


Don

Thanks for the feedback everybody. It was very helpful.

Normous, How do you clean your vanes after scuffing them?

Also, how much adhesive do people use? Should I use enough adhesive so that is spreads out a bit onto the shaft beyond the vane?


Thanks Again,


Don

Seeing as I am stuck home for the next period of time I am going to take advantage and build some bolts for the fall. I was wondering what people find to be the best adhesive for fletching and do you also use an adhesion promoter to go along with the adhesive? I will be fletching Blazer vanes onto c...

Hi Don,

Thanks for all your help! Happy birthday and have a wonderful Xmas.
