Tiller - What does it do actually? What is its purpose?

Mike,

That certainly helped me better understand what tiller actually is, thanks.

If I did it would have to have the title 'NOT DEAD YET' but getting close

All the best for the new year Tracey

I sit with bated breath for your proof, mathematical, or otherwise, that the tiller on a bow should be the same for both limbs (popularly known as zero tiller). If you can't provide this proof then a retraction woiuld, i feel, be appropriate.

Don't state your opinions as fact unless you can back it up.

I have just attended an excellent seminar delivered by Keith Gascoigne of KG archery who categorically stated, and demonstrated with the limbs he builds that a recurve bow requires a tiller of approximately 5mm greater dfference on the top limb.

I will leave it to the likes of Border Archery to explain the mechanics behind it because they too build tiller into their limbs and are much better at explaining it than I.

If the upper limb tiller is (or should be) greater than that of the lower limb, is there a manufacturer's recommendation, or is it simply a matter of tuning?

Actually (this is just very quick reasoning, and may be wrong) the riser is not perfectly symmetrical top to bottom, so one would expect a difference in upper and lower tiller. Wouldn't one?

Emdrum in No 10 reply gives a good explanation for it all, and this may explain the fact that the manufacturer can only give recommendation as a guide line, as no two archers shoot exactly the same, just simular.....

Because each bow's geometry is different, the manufacturer's recommendations make a good starting point, but because of the reasons above (i.e. your individual grip and hand position on the handle and your fingers on the string) this will rarely be exactly right.

Generally, if the centre of effort of your grip is lower then the tiller would be greater. If the centre of effort is closer to the arrow then the tiller would be reduced. By how much is down to the individual archer and the equipment They are using.

And yes, Keith Gascoigne does know his stuff. In the absense of other specific information, 5mm top tiller over bottom is not a bad place to be.

Cheers,

Mike

I shoot unlimited compound only and the info as far as I know for this style of bow is correct? The member asking the original question did not state what style of bow he uses. If you have problems with this, that's your prerogative. Should you wish to take issue then I suggest you contact the pro shop that sets up both my bows for me! a shop Nottinghamshire.

Please though, do not get onto what looked like an arrogant, supercillious pedistal, which is the impression you gave me. I was only trying to help.

[emdrum]

Pete-60 has a good point here. In my previous post, I was referring to tiller on conventional bows rather than compound bows. I have a Bowtech Guardian and the tiller on that is set to zero, as advised by a shop. It shoots great.

I would surmise that issues of cam timing and bow symmetry override the tiller issues in the case of the Guardian, but this is only a guess on my part. This may not be the same for all compounds and, once again, I would advise following manufacturer's recommendations for the bow that you are shooting.

Cheers

I think this is very unfair, Pete-60 was expressing an opinion based on what he was told by Simon at a shop who setup his bow. If everyone on this thread only posted what they could prove factual then it would be a very small forum indeed.

Your tone and attitude may put genuine members off answering questions such as this.
