Title: How to set up tiller on an ILF system
Post by: bearhair on December 03, 2007, 05:38:00 PM
I recently purchased an ILF riser from Bob Morrison and a set of his limbs.  Shoots 42#@28".  I was wondering about playing with the tiller but I really don't know what to expect as far as what effect different tiller will have. I've only ever had a 1pc recurve.  

So I guess my question is, do I just set the tiller slightly positive for split finger and foorget about it or should I be tweaking it to find a "sweet spot"?  But then how will I know when I hit the "sweet spot" as far as tiller is concerned?

Thanks.

Most of em I have played with liked an even tiller and I shoot split finger. Against the rule but thats what I have found.

A bow's tiller is usually has the lower limb shorter than the upper limb's tiller.If you don't want to mess with the tiller and want it to remain as is and want to increase poundage,always turn the poundage adjustment screws equal amounts.

I set mine to even for three under or 1/8 pos.for split finger.Shouldn't have to adjust any more unless you are trying to compensate for bad form and then it would be better to fix your form.

The sweet spot comes from adjusting preload to match your draw length.You are trying to find the flat spot in the force curve and match it to your full draw anchor.The reason is that small variations in draw length won't have as much affect on arrow impact.

All that is fine but probably won't make any difference to the average shooter at 30 yards or under.If you can shoot a group at 30 yards that the shafts all touch it might be worth the effort.

My Morrison ILF is set at even or 1/16" positive tiller top limb and I shoot split finger. Try different tiller and nock point combinations to get the lowest nock point and still get clean and straight arrow flight. Have found with my style of shooting that I get lower nock point with even or just slightly top limb positive tiller. Normal 1/8" creates higher nock point.

Thanks for the explanation guys.  Now that I have my basement 15yrd range set up I'll have all winter to tinker.  Even though I know she isn't set-up perfectly she certainly is a sweet shooter.

Just for fun, I put the top limb on the bottom and the bottom on top of my morrison shawnee. They're dakota limbs. I strung the bow and did not notice any difference at all. I told Bob about it and he just kind of laughed. I believe you can get any bow to shoot good by moving the nocking point up or down for proper arrow flight.

The safest thing to do, and the simplest, is what the folks at 3Rivers recommend for the Dalaa. Bottom out the limb bolts and then back them out 2 full turns. That is the maximum stress point for the limbs. At that point if you want to adjust the tiller/draw weight you can fine tune it to suit yourself. I find that even or zero tiller works very well for me and others....you may be different.

I had my last fita rig set at even tiller.  I tinkered around a bit with it, but always came back to even.
