Outside shelf wear
« on: June 10, 2020, 11:22:16 PM »
I have a buddy who is shooting a bw bow he has a short draw length 26" it's 48lb he's shooting now 500 spine shafts with 200 grain up front. Have noticed that the outside of his shelf is wearing real bad. Confused as what the issues could be. Arrows fly good but I'm thinking his shafts are just a little stiff as he does have a tendency to shoot left he tried some 600's with 145 grain and got.good arrow.flifht also...was wondering.if anyone had any suggestions? Thanks

It might be helpful if you could attach a photo of the worn area.  It's a little hard for me to visualize what's going on.

It’s a good photo; shows exactly what’s going on.  Typical BW calf’s hair combination rest/strikeplate with the hair worn off on the high point of the rest.  I can also see wear on the strikeplate, but not as much.  To me, it doesn’t look like wear on the outside of the rest.  BW rests are very narrow, and it looks like wear on the normal place the shaft would rub.  How long did it take for the hair to rub off?  I’m not sure there’s really anything wrong here, although maybe someone will see something I’m not seeing.  One thing that could cause this other than just normal wear would be if the shooter is using a split finger grip and is pressing down with his index finger on the nock of the arrow, thus causing excessive pressure on the arrow rest.  In this case, the hair would probably be removed while drawing the bow with excessive downward pressure on the arrow nock, rather than when shooting it.  The problem is not so much wear on the arrow rest, but the rebound of the arrow away from the shelf when it is shot, which would show a persistent nock high if you were to bare shaft tune, and some loss of accuracy.  If he is doing this, the cure is to lower the string elbow a little and make sure that the drawing pressure is straight back, string hand relaxed, without downward forefinger pressure on the nock.

Thank you very much for your feedback..he's been shooting that bow for about 8 months I guess..he shoots 3 under but he does have a high elbow so possibly some of what you mentioned is actually the reason...once again thank you ..

I wonder if it could be something as simple as pressing down on the arrow with the forefinger of his bowhand while he is drawing the bow to keep the arrow from falling off of the narrow BW arrow rest?  I have that problem sometimes myself.  I take it as an indication that I haven't sufficiently relaxed my drawing hand, which usually solves the problem without any help from my finger, but if there is wind blowing the arrow off the rest, sometimes I have to keep it in place with my finger.

Another possibility is feather contact. I have a similar wear pattern on one of my Widow recurves that I shoot arrows that are 4" 3 fletch. My other Widow shows no wear pattern and I shoot 4-4" feather fletched at 90 degrees. I've seen more than a few Widow recurve shooters that shoot 3 fletch with the cock feather in or they rotate the nock slightly to allow fletch clearance on the outside of the shelf. I think there is a video on the Black Widow site or on YouTube that has Ken Beck showing some different tips for better fletching clearance.

Could be several things causing the hen feather to hit the shelf; nocking point too low or arrow too stiff. Might be as simple as turning your cock feather in to eliminate the contact. The hen feather should be showing some wear.  If an arrow is properly tuned, the feathers shouldn't show any wear from shelf contact.

Here's a video that shows how a "properly" tuned arrow will clear the riser.  It's been my observation that most "traditional" shooters use arrows that are waaaaaay too stiff.

No wear on feathers he did change knock point guess now just have to wait and see as he's changed shelf material also. Been no sign of poor arrow flight that's was why the question thinking has something to do with him and his grip too...lol thanks again
