I cannot recall where I had encountered the article. I had the same question as you in 2014 as I was preparing for a hunt in New Zealand. The article would have been written in 2014 or before. Personally, I have had numerous bare shaft-only sessions out to 40 yards shooting multiple +/- .003 shafts. The +/- .003 shafts have never been an issue. Can't even say with any certainty that any +/-.006 shafts that I have bare shafted caused me any issues.

I'm a very amateur bowyer. I built a bow every few years so it doesn't pay for me to get the expensive finishes.
I am wondering what rattle can finish is being used?
I did my last bow with several coats of Dupi-Color wheel matte clearcoat and then a couple of coats of Krylon colormax flat crystal clear and it has cracks on the belly side after shooting just a couple of times.
So any suggestions????
Thanks

Made some progress today. Got grip rough cut and limbs initial profiled until I verify string alignment.

Mike, ya home yet or ya gotta stay a day or two?

Kirk, I had the epidural steroid injection between L4 and L5 last August 20th and it really helped me out. Now I gotta get one in the right hip May 1st. There are times when it hits me that I need crutches to walk for 4 or 5 days.

Kirk, here you go. The tapered lam has a .003 forward taper and the last 6 1/2 inches before string nocks goes into a .004 reverse taper, kind of a integrated wedge.
Specs: lengt 64 inches ntn.
From belly side:
Bjorn glass .040
European Walnut thin veneer
Tapered bamboo
Riser 22 inches
Bamboo parallel
Bamboo parallel
Stabil kore
Walnut veneer
Bjorn glass
Riser is made from 3 pieces of Jatoba glued in I beam configuration.
As this one is the first off new form we shall see how it work out.
Have adjusted it today so tiller is dead even on both limbs measured from three points both on brace and 20 inch draw.

Spine target and consistancy are the more important factors.

A study having 5 Olympic archers shooting 50 yards whole increasing the straightness. All 5 were able to keep the arrows in the bullseye until the shafts exceeded +/- .005.

I'd be interested in reading that study. Do you recall where you saw it?

Agreed Kirk. But, if you are able to stabilize the wood thourghly first, I have had zero issues with the wood moving next to the composites. I have risers that sit in my garage or shed year round in Iowa from high humidity 100*+ to very dry -10* temps and no problems at all with the stabalized bows.

But......not all wood stabilize well, especially the oily varieties. Bocote is one, I stabilized some of it one time, and while it stabilized OK, it ruined my batch of Cactus Juice. You could literally see the oil coming out of it with the air and it turned my juice into Root Beer.

For those of you interested, here is a link to my supplier. Been very happy with them. If you are just using the G10 for accents, limb pad caps, and tip overlays etc, it pretty reasonable. I use .031 alot. For I-beams the .375 will run about $20-$30 per riser depending on the size of your riser block.

I never got into stabilizing wood much using cactus juice. i got set up years ago with a vacuum chamber and messed with it a bit, but it was short lived.

I buy my G-10 FRP in 2-3' X 4' sheets. in 3/8" & 1/4"  directly from Professional plastics with no shipping cost.... Yes... Its expensive, but i use it on ILF risers , Bare Foot risers, and my Sasquatch Special with a full overlay G-10 back, as well as I beams.

I have pretty good luck if i cook the riser after it's rough shaped in the spray booth for a couple days at 100 degrees. if it's going to crack or open up, it does it then and i can fill it before finish sanding.  I could probably do the same thing in my hot box, and have a few times.

I'm repairing a B&W ebony one piece right now that shrank real bad. That material has been bone dry for quite a few years too. Sometimes it makes no sense at all....   Kirk

Nice looking bend to that one.

Did you use tip wedges?  and....What taper rates did you use?

Thanks

Microdisectomy removing herniated disc off a nerve going down my leg.

I feel your pain brother... literally. I've been battling bulging discs for many years and dodging surgery. i've have had epidural steroid injections about every 4 months the last 2 years that has kept things to a dull roar, but my last shot just before Christmas didnt do a damn thing.  So i've got an ablation  therapy scheduled for early May.

I'm hoping this works or i too will be looking at the same surgery you are having.  Good luck on that one...   Kirk
