Bareshaft Impacts

You get a flow inversion (lift goes negative) at around 50 metres and at different times/position for the bareshaft and fletched arrows so, in theory, I would agree with this - I'd put a 40 metre upper limit on the bareshaft tuning method to play safe.

Close, but not quite...

What, in particular, (apart from the fact it's yellow!) is the difference between Jay Barrs's bow and most others in the world?

Bingo!

So while low and left may be good for Jay Barrs, it's actually on the WEAK side.

Most right-handed people who tune for low left, are therefore putting their arrow on the STIFF side.

Whether you choose to follow someone else's method of setting a bow up is entirely up to you, but if you're going to follow, at least do it properly!



(I've personally always shot weak arrows because the only ones that come out stiff are ACE 400s with 2 inches off the back. God knows why...)

Dam, I was keeping that quiet so I could be a smart **** later

I too am left handed and find especially with ACE's that they group better if they are slightly on the weaker side. I think I remember Easton did suggest this many years ago.

This is a straight question as I do not know the answer.
When Jay barrs did his tuning and published his results, is the low left being taken out of context?
Did he do his initial tuning to get the bare shaft in the group? Did he later do some fine tuning to get best groups? Did he then find that after the fine tuning, he repeated the bare shaft test and found it was now low left?
I think the low left bare shaft would then be a quick way to get his best results without going through both processes again. Copying his results would seem to me to cut out the fine tuning, assuming that it would be the same for everyone. Which may or may not be correct.

Hi Geoff

He went through all his tuning and found that when he went back to 18m this was the result. This was also done at a time when A/C arrows were quite new to the market, not withstanding that he is left handed showing that his arrows were on the weak side and somewhere it has been translated to RH archers. You are right the final 18m bareshaft test was so that in future if he had to tune quickly he could just shoot at 18 and replicate his result.

Thanks for the confirmation , Whitehart. I thought I had read about the process and it involved more than bare shaft tuning.
Amnesia! What amnesia? I don't remember anyone mentioning amnesia.I've forgotten how to spell it and would you believe it, it isn't in my dictionary. Perhaps they forgot.

why should you accept bare shaft planning at any distance? it can with patients be completely eliminated, you get greater energy retention in your arrows that in-turn creates less effect of wind drift and improved (though only marginally) sight-marks

Perhaps it was because the wise man couldn't get his own bow tuned

Personally, a bareshaft tune at 30m is reasonable for me at my skill level. I've shot a few at 70m just as a check, normally they're in the group if I've got the tune right elsewhere.
