I have and have had a few takedowns using the bow bolt system. On one bow when unstrung the interface between the two halves is very tight. However when strung there is a very slight gap on the back side, minimal, just enough to see light through or about the thickness of a piece of paper. Bow shoots great with no creaks or undue vibration and the gap doesn't bother me. Gap has not increased in size and the bolt is completely encased in micarta. My only question is wondering if this is normal for this takedown system? I should add that's it's a reputable bowyer and all aspects of the bow are impeccable. Thanks.

Very difficult to machine a light tight gap when something is under side pressure like that. It is most likely the little tolerance slack in the threads. Without getting into specifics male threads are cut to slightly smaller size than female threads or they would not go together. There are different classes of thread fits though. Finer threads are generally tighter tolerances. From a machinist not a bow builder's perspective.

It's a difficult build especially afterwards.But if it doesn't change there's not much to do but shoot it.

Yes, I had that on one once. It was the only bow bolt I ever had so can't say if it is common or not. Shot that bow for almost two years and no problems and was a rock solid hook up. I put a leather two piece grip on it and then you could not even see the little gap when strung.

Black Widow manual says normal to have a very slight gap

The older bows that I have are like that because the bolt us centered. The newer ones have the bolt closer to the front of the riser, and there isn't any noticeable gap when strung.

I believe the gap is common. If it bothers you, put a Shur-grip or bicycle innertube over it that is quick and easy to roll down for disassembly.

thanks for the responses guys. Great explanations. Like I said, it doesn't bother me, I was just curious as to the prevalence.

The gap is common in many of the older ones, Most of us that still use it have adjusted the positioning of the Bow bolt to help fix this issue. It is part of the learning curve when building them. We have them in some bows up to 70lb. and they are holding tight.

I had that problem on a take down I made. Scared me, reassured here by fellow wallers and have had no issues. John

Thanks again for the info guys. See that's it's a non factor in the bow and will continue to enjoy shooting it. Wish you all the best of luck this season!

I’ve had at least 5 or 6....Toelke, Turkey Creek with no problems....I like the added weight in the grip.
