Uukha Weight Rating Problem

[StopMakingSense]

I'm very new to the trad/ILF world and wanted an opinion on this one. I ordered 50# Long Uukha Mazaalai limbs but the weight rating seems light and I'm now considering to open a warranty claim.

I’m only getting 50.1# OTF @ a 29” draw with a 17” Satori. I was hoping closer to 54# given 1lb per riser length and 2lbs per 1" above 28". Even tiller was achieved with top bolt maxed and bottom bolt turned 1-1/8 out.

I understand the tolerance for Nature is +-2.5lbs which gives me a range of 51.5-56.5#. This makes it seem out of spec compared to the Uukha calculator.

What have others found with Uukha Nature limbs on Satori's and stated weights vs DL & riser length?

At uukha, every shot is a celebration of excellence, a moment out of time. We believe in the power of a perfectly shot arrow, in the beauty of a mastered gesture, where every fiber of the limbs vibrates to the archer's rhythm.

In hindsight I should have just ordered Sigma limbs for a tigther tolernace because I did care about finished weight.

Call em up, or call the vendor you bought through. That weight seems fairly close to what I would expect, but only calling Uukka will let you know if they agree.

Another thought, my Satori has pretty chill limb pad angles. Maybe on a DAS or something with a more aggressive limb pad angle would get you closer to 54.

Thanks, this is the feedback I was looking for, appreciate the insight

@nevadabugle So what you're saying is the Satori doesn't have very agressive deflex in the limb pad angles vs say a DAS or CD WF17?

Yes. I always mess up reflex vs deflex in my mind, but some risers put more preload in the limbs than others.

I have no experience with the WF, but my DAS riser has more preload that my Satori riser. Its not dramatic or anything, but in your example it may give you an extra pound or two, which would put the limbs in spec.

I bet over on TradTalk Forums, you can find guys that know the actual limb pad angles of the most common ILF hunting risers.

The opposite. The satori is a pretty deflexed riser. I always lost 2-3 lbs on it versus something like an Optimus /f261, Gillo ghost, etc. Those are all 19”, but still.

What he said. He is agreeing with my input and why i used preload over reflex/deflex. The satori is a mild riser compared to some. Less preload means less draw weight.

Think about it this way, tightening a limb bolt gives more poundage and more preload. Loosening a limb bolt reduces poundage and preload. Some risers are machined with more or less preload.

Bingo! Or Yahtzee. Something. I got tired of my overthinking brain buying and then selling so I quit ILF, but a couple things. David Sosa said years ago not to go over 12 lbs over the marked weight on limbs. True, I’ve blown a few. It’s usually best to be 11/2 to 2 turns out. Bolts down doesn’t mean quieter usually, or any real benefit.
So saying all that, FOR ME, doing the math and picking limbs I think we’re a couple lbs heavier than my goal knowing I’d be turns out and could take more worked the best. Satori you have to be careful with though, their max turns out is less than some. I try to look at the bolt face and limb and try to have it pretty flat. Safer on the limb and quieter, and a limb not maxxed out( or over) on preload last longer and shoots quieter. But, I have a 31” draw, which could make all this useless info…..

My limited experience after literally 10 minutes mucking around with my first set of Uukhas this morning.

I have long Mazaalais rated to 45#, which is on a 19in riser obviously.
On a 21in Satori riser I have here they are pulling 40# on my fingers, which happens to be 28in draw.
I just put them on a 19in Tradtech riser and they're pulling 45# on my fingers.

My 55# medium Satori limbs are 55# on my 19in Tradtech riser, and 56# on my DAS 21in riser. I haven't rated them on the 21in Satori riser yet but I imagine it'd be around 52-53#.

This different limb angle stuff makes a mess of what I thought I knew about string length as well, so I think I need to switch some strings or get some new ones.

Dang it! Forgot where I was going with that, lol! So, shooting for a bit over goal weight gave me some leeway with riser geometry. Less deflex, bolts out more, a layer back riser( satori) bolts only out a turn turn and a half. Helpful on limbs where you’re not too sure what riser they’re meant for. Tip; look at the limb companies riser offerings if they have any. Many aren’t all that deflexed at all, some are. They’re making their limbs for their risers and maybe some of the more popular risers.

Thanks guys, you helped me make sense of this.

I guess I'll have to sell these limbs and go up to the Altan or Omega to get my desired 54# with the addition of having my limb bolts turned out a bit as well.
