I've found the charts showing which limbs make what length bow on what riser. I'm trying to find a chart showing at what length which brands mesasure there limb weights, and is that bolts all the way in/out/half way, etc. Anyone know where to find a chart like this?

Ilf limbs are typically marked for different draw lengths on different riser lengths. As for where the bolts are. normally its with the bolts tightened down and then backed off 1/4 to 1/2 turn,

I'm not familiar with any chart like you describe. Most manufacturers list the weight of their limbs in the middle; some however, weigh their limbs at minimum preload.

I'm not real concerned on the bolt positioning, does anyone know where one is telling at what length W&W, SF, Black max, etc. measure there limbs? Surely someone jas put a list together.

Call Lancaster. They will help you out.On some Ilf risers you can turn the bolts out 4 turns safely, and reduce weight up to 4 lbs. When you take the bow down the limbs are flopping around.A lot of those limbs are based on a 25 riser for longer bows for Olympic style shooting,66,68,70 inches.Example, I have a 58 inch long Ilf set up with 17 inch riser, and short limbs marked 38 lbs. On that short riser my bow comes out to 44lbs. max with limbs cranked in tight.I can turn the bolts out four full turns safely, and reduce weight to 40 lbs.Your best bet would be to talk to a tech at Lancaster.

If you know what it is on a 25" riser, then it's just math by subtracting the riser length as you go down. Now when you get into limb pad angle changes, then you have another dynamic to consider. I think Tradtech has a different measure for theirs, so again...how can you have a chart. Call Lancaster and find out what you are looking for with your setup...they will know that. With the same riser configuration, it's a math thing.

I'm not even sure what the question is anymore.

Secret Squirrel calls the magic word "Pre-load", so much time, so few answers.

So everyone measures on a 25" riser but Trad tech? Is that accurate? Sorry I'm new to ILF.

Biathlonman, I believe the limbs are marked as such...X inches on a xx inch riser.

PM sent.

"So everyone measures on a 25" riser but Trad tech? Is that accurate?..."

No, that is not correct. "Most" ILF limbs are measured on a 25" riser, but some don't. Dryad is on a 19" riser; TradTech is on a 17" riser and Hoyt Satori limbs are measured on their 21" riser.

You first have to know what length riser the limbs are weight on, then, all you have to do is add 1# per inch of riser length for shorter risers and subract 1# per inch of riser legth.

Example: 40# limbs on a 25" riser will weight about 48#'s on a 17" riser, 46# on a 19" riser, 44#'s on a 21" riser and 42# on a 23" riser.

That should have been.... subtract 1# per inch of riser length of a longer riser.

Nothing is exact. Limb pad angles change how much weight the limbs will lose or gain, but generally the 1# per inch of riser length rule will get you close.

Thanks Jim, that first one was the list I was looking for!

There is no chart to give you limb weights on risers for the reasons mentioned above. Best you can do is use the rule of thumb Jim C gave you above.

Now if you get into a warf bow, that’s another ball game!

Many 'target' limbs show ratings for 23 and 25" risers. For instance one of mine says "23-38, 25-36." On my 25" riser they pull 36 +/- depending on set-up. From there it's 'guess-timation ;-)

Some 'hunting' limbs are rated on specific shorter risers, so that's a different kettle of fish...

Well..... look there. Someone did put together a chart--11 years ago.

Thanks monkeyball.

While the chart is standardized not all manufactures follow the chart. My new Dryad 17inch riser has long limbs that are 45# @ 28. Certainly not an expert here but seems in looking at the Dryad website they are taking the standards and tweeking them to specific riser lengths and their specific limb designs. Of course one can use the chart with the Dryad riser whilst looking for other makers limbs.

all Zipper and ask what the preload is on your particular riser and limb poundage gains for ILF limbs weighted for 25 inch risers and down.
