When I ordered an original DAS riser I had my own limbs. David told me to look at his site because I would have to send them in to ensure they would fit onto the riser. When I got them back the limb butts had been ground down in order to provide clearance with the riser wall. No biggie but it wasn't a secret back than. I guess because the risers aren't produced any longer people must have forgotten this.

Jinks, I know those limbs can be made to quiet and smooth. My friend Scott string walks. His bow was setup without any silencers and was pretty quiet and smooth. Sometimes things like string material and strand count can make a huge difference. It may be as simple as trying a softer material to get a smoother, quieter bow. Some of my favorite bows and setups took me a good month or two to arrive at the right spot. I've had bows that I was frustrated with for the first couple weeks but I'll keep working at it until I get it right. It isn't until I've had one for a few months that I'll consider selling it because it may take that long to figure out if it'll work for me.

One other thought, why use light arrows if you stick with closer shooting? Nothing wrong with a heavier arrow if the bulk of your shooting is 30 yards or less.

Than again, nothing wrong with sticking with the wood bows either.
Two key notes in this Post from Chris for Ya, Jinks...#1...Try a string made of D-97, if you haven't already done so, or 452-X..I've found both of these string materials to be quiet on my bows, 14 strands of D-97, and 16-18 strands of 452-X...#2...The heavier arrow thing...If most of your shooting is done at closer ranges, in your yard, You might be better off running a heavier arrow..???....Worth a shot....pun intended...;)...........Jim

Thanks Str8!...and BTW?...I really appreciate when you chime in during moments like this as you have a spot permanently secured on my shortlist of those I consider to be my...."Voice Of Reason Mentors"...just wanted to point that out and say thanks for that! ;)

Moving Forward:

My thoughts today relating to this latest dilemma of a rig here included but were not limited too...

Thought #1. Cut your losses and sell it all...everything I have left that's ILF...which ain't much but is this DAS Elite Riser with the RCX100 Limbs and Robertfishes custom limbs...just to be done with all things ILF.

But then stevelong came along and mentioned...

"Also, it was not long ago this red riser was the cream of the crop, you had your friend's (?Robertfishes ?) limbs on it, and it shot great, quiet, and all of that.
GO back there, to that configuration.
as with all things, there are things to the left, to the right, and there's the middle.
PROVERBS teaches - avoid the extremes, it's all about BALANCE, in all things."


and that tugged on a heart string of mine cause he's right...I loved this riser with Roberts shorts on it...real smooth drawing (especially for shorts) and fantastic performance without the noise...which led too...

Thought #2: Put Roberts limbs back on the DAS they were made for and sell the RCX100's...but then I....

Thought #3. Wondered who's going to want to buy a new set of RCX100's that I whiddled away on to fit my DAS Elite?....which led too...

Thought #4. Take these limbs and put them on the riser they were designed for and just buy the matching RCX100 riser to go with them!

But that scared me cause then I thought about just how Pi$$ed I'd be if things didn't improve then...and then I thought...cause you know that would require extensive tuning to get it right as well...which landed me on...

"QUIT BEING SUCH A PU$$ and Deal With What You Have!"

"MAKE IT WORK!!!"

so?...that's when I engaged what's left of my stroked out my pea brain and started getting proactive about what positive moves I could make and they are....

1. Lose The Glove!...I forgot all about the fact that I've dropped well below 40#s Hold Weight...and at 36#s?...no question...I should be using a tab!:cussing:

2. Cut the new rubber cat whiskers that came pre-installed on the new 21strand BCY-X string and lett'er sing and when you get it right?...install puffs instead...after all...I've found cat whiskers to be both heavier and louder than puffs.

3. These RCX100's have a fair amount of curve too them for what's considered to be standard profile limbs and as such?...have beyond a fair amount of Flemish Braided String End making contact for quite a ways on (what seems) the limbs longer than normal string grooves...yarn wraps would be a great idea there.

4. LIMBSAVERS!

5. I'm also questioning myself about my rest as...why am I shooting fantastic preforming limbs on what I feel is a world class riser and doing so off a leather strike plate and shelf?....I'm thinking a high end stick-on flipper with a decent plunger would be more fitting on this particular set-up cause the one thing that did make a positive improvement last night as I wrapped things up?...was mounting up my 10" BeeStinger stab...that move alone seemed to eradicate about 1/3rd of the noise.

6. Wind the Limb Bolts in too max 38#s again.

7. Tonight?...I'm also going to try it out with the limbs on upside down...that's how I accidentally first shot it over the chronograph and it seemed much quieter that way than it has since I switched them too right side up...and if that's a fact?...my next move will be trying to remove all the logo's without damaging the limbs cause upside down looks stupid.

Cause it hasn't sounded this quiet since I shot it that way...you know...back when I was still actually impressed? LOL! ;)


wish me luck. ;)

I have no doubt it will all work out for you JINKSTER one way or another.

What grinds my gears is the fact that you were forced to carve up a brand new set of top end limbs just to get them to fit on your riser, only to find out they might not be what you anticipated when you ordered them. Had that not been the case, you simply could have packaged them back up and sent them back. No harm, no foul. Happens every day.

Instead, it takes the best option off the table which is to just return the limbs. Second, like you said yourself, who is going to want to buy a brand new set of limbs that have been whittled on? I know I wouldn't.

Fortunately, Robert knew you were using a DAS and built his custom limbs accordingly.

Yep, it ticks me off every time I see someone go through this. Sorry you had to experience it.
 
I know the fact you had to hand fit the limb to the riser is annoying and something you weren't anticipating (I wouldn't have either), but it seems like a pretty nice bow at this point.

Glad it worked out, live and learn.

Whoa...hold up a second here...while I appreciate your sympathetic demeanor?...

Let's take the DAS Riser out of the equation...or better yet?...let's say I spent 1/2 hour on a Bridgeport and milled away more than adequate clearance to accept and depth U-notch limbs out there...because than that would leave me...

"Still Whittling!"

because the U-Notch width wasn't to spec dimension either at .371" wide and is supposed to fit a standard .375" diameter limb bolt how?

And the same situation existed with my Hoyt F7's...their top of the line limb...but worse...their U-notch measured .368 wide.

You speak of "What Grinds Your Gears"...well what grinds mine?....(especially as a life long precision machinist)...is when there are B/P's out there with hard basic dimensions and folks take it upon their self to stray from them...for whatever reason...but there's simply no GOOD reason....in a word?

"UNACCEPTABLE"

and who gets to pay the price for their tomfoolery?...us.:cussing:
 
Jinx, at least you know enough to make the needed mods. Those of us that are skill and talent challenged vapor lock at the thought of pulling out a file and making the limbs fit. I am never sure whether the initial fit issue is the bow, or something I am doing wrong. I liked how you took Zeuss completely apart and rejiggled it to make it straight. I would not have had the nerve to do that. I would probably get it back together and find a few extra screws and washers left over, with no idea where they were supposed to go.
 
Why not just rebuild the plates so that it'll take standard limbs? Could do them in 303 while you are at it for a bit more mass...

Grant
and what about the limb bolt holes that are threaded clean through the riser?

long before I did that?...I'd simply mill away .100" extra clearance off the riser itself....but then?....all that extra clearance would look pretty dumb when I used limbs that were made to specified dimensions...and they are out there as well.
 
In that original video the bow sounds acceptable to me, good luck Jinks and let us know what you come up with.
 
Just so you know, my DAS one of the last ones by David has the same problem. Like I said earlier in this thread, spend some time with it and see where it leads. But you didn't wanna hear it at the time.

.
The limbs don't register on the bolts so it really wouldn't matter. Making new plates would be simple as pie.

I did a bunch of Googling to figure out what B/P's are. Never found anything pertinent to machining and then figured out on my own that it was blue prints. I was so pleased with myself. I was never good at acronyms.

Okay...silly me....what was I thinking?

Everyone knows that there are absolutely NO BLUE PRINTS OR HARD DIMENSIONS anywhere for this International Limb Fitment, I.L.F. limb attchment system that dozens of major manufacturers make world wide?....and with no blue prints huh?

Well I gotta hand it to you folks cause that would most assuredly explain QUITE a lot! LOL!

but ILF Rox huh? :lol:

well you couldn't prove it by me! :lol: ;)

Still doesn't.
You're right....I don't...and here's why...

First things first so let's get this cleared up right up front...it is my understanding that my DAS Elite is one of the few originals that were supplied as ILF ready and are not aftermarket ILF adapter plates like these offered by 3 Rivers...

Image


Here's mine...

Image


in this next pic?...please note that while there are no "Load Bearing Witness Marks" on the radius bottom of my ILF Dovetail Slot?...(not even any missing or distorted finish)...that there is Load Bearing Witness Marks on my Brass Limb Bolt Bushings...

Image


and in this next pic?....we can clearly see that the minor diameter of the ILF dovetail stud lands well before the end of the dovetail slot....

Image


with the limb well positioned and abutted against the limb bolt bushing.

Image


now...you were saying? ;)
