i just bought a bow for my wife. it has a bushing for a plunger button. will setting it up to shoot off shelf change the tiller too much or have any adverse effects?
she shoots 3 under.

the arrow will be at least 1/2" lower if i set it up to shoot off the shelf. ie- much closer to her hand.

The tiller will be fine. You will just have to adjust nock height. Make sure the contact point is directly above the deepest part of the grip, this will make the bow less sensitive to the tiller.

thanks. i'll give it a go.

Clint ...
i find its nearly always  more a nocking point issue than a rest issue .....
And good going getting the wife a new toy... i bought my missus one ...been fired just the once....in three years !!!!!

cheers

Clint,  if it affected tiller, no one would ever be able to string walk with any effeciency.  Small movements in rest and/or nocking point, have little effect on the tiller...or the tiller on them.  What you usually find with an elevated rest is limited contact and better flight characteristics...along with the ability to use several spine variances more easily.

If shooting barebow/instinctive, it only takes a few shots to get used to the difference.

good point george. i forgot that some people are string walkers.  

Hopefully you will be able to tune it to shoot off the shelf.  I once had a Hoyt Gamemaster II that I couldn't tune to shoot off the shelf.  The bare shafts would nosedive into the ground, even when the nock point was set at zero.  The bare shafts flew fine from a rest about 1/2" above the shelf.  I even tried reversing the limbs, in case they were marked wrong, but no go.  Since I only like to shoot my bows off the shelf, I eventually sold that bow to someone who wanted to shoot from the rest.  It's possible that someone who didn't bare shaft tune might not have minded, as the fletched arrows seemed to fly okay from the shelf, but I wasn't happy with it, knowing that the bare shafts wouldn't fly well from the shelf.

The same sort of thing is true in trying to re-tune a bow tillered for split fingers for 3 under.  Most of the time, they will retune okay, but there is the occasional bow that won't.

Last summer I removed my rest and tried shooting off the shelf.  I was kind of worried about it because I had never tried it before and wondered how it would affect my shooting.  

It didn't take many shots for me to get comfortable with it and question myself why I had a rest in the first place.  I mean the rest worked but I shot just as good without it.  

I always carried an extra stick on rest when hunting but now it is just one less thing to worry about.
