Tuning a new batch

[skinner biscuit]

I made a new batch of arrows with some goals in mind. First, I didn’t want to build out the shelf plate . Second, I wanted to go back to a screw in broadhead, so my brass inserts are all the same in relation to field tip/ broadhead.(plus I want to replace broadheads with field points in the bow quiver when practicing) I’ll number them to keep track. Lastly, I wanted a lower brace height for more power stroke.My Boyer’s recommended brace height is 6 1/2” to 7 1/4” and I settled on 6 3/4”. I’ve done the straight line on the target and got fair results in the past but also a bucket of too stiff arrows as well ! I find this method a time consuming/head scratching ,not  at all dummy proof . A better method I found , is to put a block target chest high with a dark shaded background. I take a 14’ step ladder, mount my I phone on a tripod on top and set it to slo mo video.I take 2 bare shafts, shoot twice , standing in front of the ladder . I don’t care where my shaft hits on the target and I give full concentration to form and release. Shoot twice. Watch . Analyze. Cut. Do it again. When I was satisfied with my results , I fletched up three arrows and grouped tuned, to check my results. I shot a little to the left but as you can see the bare shafts are impacting pretty much the same. Brace height 6 3/4” shelf plate .125. Arrow weight 694. 1”aluminum footing.Point weight 300. Brass insert 50. Broadheads  will be 225 Tuffheads with 75 steel insert. I posted a couple years back about this method and Clay has a similar one now on Twisted Stave.

Have not tried this method myself – but definitely looks like an easier more fool proof ( and quicker ) method, than the ones I have used in the past. I will try it for my next bow / new arrow work up . A good use for modern technology —–

I did some fine fletched arrow tuning. I ended up lowering the brace height to  6 1/2″ (lowest recommended setting) and cutting off a 1/8 inch.The bow is centershot ,putting all the energy from the limbs to the arrow as opposed to building out the shelf plate. No feather noise whatsoever and perfect arrow flight. Total weight 692. FOC 26%

Both bare shafts are stuck in the target nock left as compared to the fletched arrows.  This might indicate a weak shaft…  But as heavy has your points are, I expect they will sink all the way though whatever you hit with them!

Steve’s  comments are spot on as usual. What spine shaft are you using? Although it looks like the arrow set up you have, will work fine.

Your foc and arrow weight are where i like to have mine.

I totally agree! All those arrows in the pic ended up getting a 1/8” spanking on the cut saw for misbehaving!! Arrows are gt 340 XT traditional.

Roger that. Sounds like you are on top of it, and have it were you want it. It is handy to be able to go back and forth with different tips that are tuned. My carbons are all set up similar to yours.

Happy Arrows ! As they say in Argentina —

Finally figured out how to post a video ! Thanks web mom! If you try this ,one cool thing is you can stop and use your finger to manipulate the frames of your image or blow it up . I can actually see the archers paradox and when I first watched it I thought I was plucking the string . Stopped the frame when the  arrow was well past the riser and to my relief my string hand is firmly anchored to the corner of my mouth.

Haha, way cool—– Self – coaching — the wonderment of the modern cell phone

Amazing , still have a hard time wrapping my head around the magnitude of the technology, in that small device and in so short a time period.—- BUT— beyond this place there be Dragons!

Happy Arrows

Here’s the results of my endeavor. From 10 to 25 yards . Starting with a cold shot at 20.(target set at elk vitals height … )

Yeeehaaa! Excellent shooting . I think you are there. You’ve inspired me to go out and practice– grabbing my bow and heading out to my backyard range.

All ya all have a great holiday, and get out and shoot some arrows!

I did something similar to your set up. 50 gr inserts, 225 tuffheads, 75 gr adapters, 300 grain field points, and for stumpers, 100 gr inserts, 125 gr adapters and judos, with collars fore and aft. Makes a very durable stumper, but dang hard to pull out sometimes. They will snap if I side swipe a tree, especially a sapling. They seem to pretty consistently snap off clean about 3 1/2 inch from the head.

David, here’s a ace hex head 2oogr . Hit a solid and split the casing. Arrow no worse for wear ( lucky it didn’t crack the nock end) Shows how tough a carbon shaft with a brass insert is ….when footed!!!

That’s pretty tough. I never tried footing. I did try hex heads a couple of times and they just destroyed the shaft. Judos sink in a bit and these things just bounce back. I bet they’re great for small game though. dwc
