Bare Shaft Result Help

[Big Boy Blue]

Guys

Many thanks, all the advice it has helped realise that I need help (badly). So this afternoon I will be going to my local archery store for an afternoons session.

this makes you wonder about all the methods used to tune, no substitute for good old suck it and see added to getting the basics right.

However you dress them up there are only two basic tuning methods.

and they are?

Fletched arrow flight (aka walkback) and compared fletched/bare shaft arrow flight.

Other possible approaches like doppler radar and arrow speed measurement require specialist kit not available to the majority.

The key words in the post by cliveanne was 'release aid' you cxant expect a release aid to give the same results as fingers.

Don't quite understand as Phil is tuning a recurve/finger release.
Arrows fly exactly the same way however they are launched so I'd go for there being two tuning methods whatever the launcher.

I have to give a big vote of thanks to Stan at Chiltern Archery who has spent 2 hours with me this afternoon helping me sort things out.

When we finished at the end of the couple of hours the bow is tuning nicely to the 1816 spines without any problems. So what did he change, well its as follows.

1) String Change from 18 strand FastFlight to 14 strand FastFlight.
2) Reduction of the brace height from 22.4cm to 21.6cm.
3) Softened the plunger by 2 full truns.

The unfletched are now landing about 1-2 inchs away from the fletched in the 7-8 o'clock position. My fletched grouping has also improved nicely.

As for the comments in a previous post regarding the experiments which concluded that no matter what you do the unfletched group will allways land in the same position. This is completely contrary to what I have seen with my own eyes today. All of the changes made above had a visible effect on the position of the unflecthed group.

Again thanks to all for your comments.

Congratulations - here come the scores (but there goes one excuse )

Bit of serious 'bow bending' but a reasonable result - just have to remember next time you buy arrows if nothing's changed to get weaker arrows. (contrary to popular opinion weaker is better than stiffer)

The tekkie comment above does not validate/invalidate the bareshaft approach - sometimes taken that way unfortunately. Whenever you see the words 'coach opinion' time to get out the garlic.

Did anyone actually say that?
