Title: ILF limb and riser chart
Post by: ny state land on April 07, 2018, 12:46:13 PM
Not sure how much interest there is but here is a chart for putting together an ILF rig.

To further add to that chart, here is a chart for maximum draw length for each size limb. I advise people to first choose the best length limb to match their draw length and maximize the performance of the limb. Then marry that limb to the size riser to make the length of the finished bow you want from the first chart.

It's important to note that these are for recurve limbs.  Longbow limbs slide one length higher.

this is very Interesting, I need a much shorter riser!

I find that a lot of guys go too long on limbs for the sake of smoothness but give up performance.
I had the chance to test a Covert Hunter in 17" riser and medium limbs vs a 19" riser and short limbs.  Both with 28" draw.  The short limbs on the longer riser gave me 4 fps faster with 3# less draw weight.
I don't think the difference would be as much with a conventional limb but the chart shows you options based on your draw length.
I would still consult the limb maker to confirm the draw recommendations listed on the chart.

Are there similar charts to help you figure out draw weight amounts from what the limbs are marked to what they will be on a riser of a certain length?

No.
Some makers indicate poundage on 17" riser, others on a 25" riser.  Likewise some limb makers indicate poundage at 3 turns out, 4 turns out, half way, or even with limb bolts diwn tight.

Even then the poundage might be off from markef.
Industry standard is +/- 2#.  I have never had a set come in light, but several run a pound or two heavy

And there is why I can't wrap my head around ILF.  If I wanted that complicated I'd shoot a compound....lol.

Great charts bought my first ILF set up really nice Morrison mini 14 put a set of Trad tech glass wood limbs great set up.

ILF is really not that hard........once you set up it's just another takedown bow. You just have to find the right riser with a grip you can get friendly with. It's fun playing with different set ups.

Thanks for posting that!
I have a question though. It’s better to shoot a short riser and longer limbs correct? Won’t that make a smoother drawing bow, To have longer limbs?

I don’t understand the benefits of long riser n shorter limbs.

Such a set up will yield less performance and more vibration.  It is smoother (not working tips as much) so target guys tend to favor such.

Awesome info!  Was just thinking about this the other day.  Appreciate you sharing it.

Short answer, no. The limbs have to match your draw length so you "unwind" the curves and get the full "ooomph" out of the limb. If you have a short draw length and long limbs you will leave a lot of performance on the table. I'm talking recurve here since I know nothing about longbow limbs.

Again, choose your limb length based on draw length and then the riser length to achieve the length of bow you want to wind up with.
