ILF tuning question

[Bluenose]

Hello everyone. I recently purchased a set of ILF recurve XL limbs that are marked 45 # @ 30, which is my draw length.  Installed them on a 17" ILF riser at 8 1/4 brace.  Currently at even tiller as I am shooting 3 under. Draw weight is approx 53 lbs at 30 inches. My question is, how many turns out can I go to get down to the 45 lb weight? I have turned them out 3 turns and draw weight is 48 lbs. Any responses would be appreciated.

Not an ILF expert by any means, but it seems like 5 turns out is usually the maximum recommendation.  Sounds like your limbs are either slightly heavier than marked or were measured on a 19" riser in which case they would gain 2#'s going to your shorter 17" riser.  You might not be able to get them safely to 45#.  Might be 46# or 47# is the best you can do.  Hope I'm giving you accurate info.

I was told by Mr. Morrison that his limbs, on his risers to expect a change of 1 pound per full turn of the limb bolt. I was advised to expect 4-5 pounds as the maximum difference from highest to lowest setting.

Thanks for the replies. I was also told that the maximum turns out should be limited to five (5) turns.  One would think however that the bow would certainly not perform to it's maximum if turned out the five turns. These limbs are supposed to have been built for a 17 " riser and were a custom order. I was hoping to be able to reduce the weight from the marked 45 lbs to around 40 lbs but I guess I will have to either buy a 19 " riser or another set of lighter limbs.

The number of turns out is dependent on your riser. Unfortunately there is no standard. I've had an Excel a Titan and a dryad and they are all different. Six turns on the Excel, five on the Titan and four turns on the Dryad. So you need to find out from the maker. By the way, at a 30" draw length, your limbs should perform very well turned out.

Risers from different manufacturers may have different limb pad angles so weights will vary. No problem shooting them wound out. Bow scales can also vary. Don't think you have to turn them all the way in. Also limb maker can give you and idea on best brace range on your riser. I am usually running 7 1/2 on my 17" riser.

Thanks for the replies everyone, I'm still rather new with the ILF system but the ability to tune to my release has really sold me on ILF. As suggested, I will contact the bowyer and get a recommendation on maximum turns out.

When mixing and matching ILF limbs and risers you need to be aware of the conversion weights for the combo.  For example if using our limbs (rated on a standard 19") you will gain 3 pounds on Morrison or our risers.  Other 17" risers will gain 2 pounds.  Also we rate our limbs in the mid setting.
