Ugh just great

Thats a Big Buck Bummer.

Definitely if you own an excal you should have a 2nd set of limbs. They seem to give it up with no real rhyme or reason. They are quick to change.

If you have a second set you can just keep warrantying the failed ones and keep a fresh set on the bow.

i know we can be passionate about our theories but i didnt say the recoil plates cut the limb the recoil plates job is to cushion the limb and to minimize overtravel of the limb after firing. when you honk down on those plates youve changed the stress points.for a limb to take full advatage of its power the length is crucial. tighten down too much on those recoil plates and youve just shortened the the length of the working limb.now the plates are acting more like the main limb bolt. the Micro doesnt have a dipped painted riser so having too much coating has nothing to do with no enough room. in fact most of my experience fitting limbs has found plenty of wiggle room in the limb to riser pocket fit.I had an issue with my first GEN limbs and replaced them with no issues in 2 years. a little birdie indicated to me that many of the issues that year showed up at the recoil plates but on the back side of the limbs. since ive had no issues the cooked limb theory i will have to go by. I LOVE MY GEN 1.

So if i get what you are saying the shoulder bolts or new spacers we shouldnt tighten down all the way and leave play?

You mentioned a camo finish on the riser, as well as camo finish in the limb pockets.. I have never seen a micro, either gen 1 or 2 with a camo riser and rail but would sure like to have one.... Any ideas where to look ? Or who to have do it ?

I just sent my gen 2 back to have the screw holes in the rail repaired and a new set of limbs put on to get my performance up to 335 with a 350 gn test weight arrow.

I asked of the possibility of having both the rail and riser dipped while there and was told that was not an option..... I was kind of bummed, as I was figuring on a one of a kind Micro. But I will be happy none the less.

The people in Excaliburs CS and repair facility are definately the best.

It's completed now and on it's way home... I can't wait to be shooting her now that I know she is up to spec.

My post about possible excess coating in the limb socket obviously don't apply here. I don't see where your limb was cut by the socket at all.

Two sets of limbs failing in a short time period (or at all) indicates that something may be wrong with the riser socket though. I would send the entire riser in to an expert for analysis if I were in your shoes.

Hope you learn the cause and please share any intel you learn so that myself and others will be helped.

Very good point made there about overtightening the recoil clamps! I agree with all your points and I'm sorry I jumped to conclusion. Thanks for all that!

Just curious how you over tighten those shoulder bolts? Or nlthe new setup with spacers?

There is a rubber strip that belongs between each recoil clamp strap and each limb. Ideally, the rubber strip under each clamp strap makes contact with the limb, but is not squashed out from under the strap at all, indicating an overtightened assembly. Whether your riser has the new style bolts and spacers or the older style bolts, the result should be the same.

As foofoo noted, overtightening those limb straps effectively shortens the working length of the limb! Bad stuff can happen then, because moving the limb anchor point from the large limb bolt out to the clamp does not allow any limb flex in the riser.

I am not an Eng. but there are inch lb specs torque on the shoulder strap bolts. I have had Excals fer 20 yrs n never have had limbs shear. Yup newer short limbed models have more stress on them. Still the limb pocket thats torqued properly should not have any problem wid shearin. Those recoil straps n air brakes would be more in-line wid that than limb pockets bein set correctly

Sure its shorter limbs more stress,but some members sound like Alfalfa Desperados ,Your making the Micro look like a Corn Calf some need to lay off the Arbuckle's a few days and use your Ankle Express and relax. [/quote]


SAY WHAT ??? I guess I'm too old to understand any of that .... I just like shooting my Micro and it in no way resembles a "Corn Calf"..

What ever that may be????

i am fully aware of how they work and are to be set up.
So..... can you tell me what the point of shoulder bolts or the spacers? to prevent overtightening correct?

I think a few people need to lay off whatever is in their coffee and get out and shoot some deer.

[paulaboutform]

That sucks Matt! I still dont think thats a riser issue, those limbs arent supposed to break clean like that. Should never happen. I was hoping that wouldnt happen when i saw your tiller last week, at least for the season.
I would insist on a spare set as well.

I 100% agree Mike. All this talk about gen 1 risers and gen 2 risers is simply FALSE. Excalibur doesn't recognize the risers that way either, they're simply the original or new designs.....and neither is responsible for broken limbs or limb issues. That makes absolutely no sense and I don't buy it. If it was a design flaw, every set of limbs would have issues. Those limbs have over 250,000 individual strands and with a properly prepared and made limb a break like that would be impossible. I believe that something in the process has changed be it resin, epoxy, glass, cure....something. Either a supplier has changed a source for a cheaper alternative that Excalibur isn't aware of, or proper care isn't being taken when mixing agents to make the limbs. Whichever it is, I believe any issue lies in the limbs, not the risers. That just makes sense to me. Hopefully my micro 355 limbs are great...but I do havea sspare set (just like I have for my Exomax, 380, and 405).

If you are aware of everything why the continuing line of questioning?

Your thinking statement may be flawed, as it is based on admitted assumptions.

You suspect correctly. He has posted the Acorn Calf crap on three forums I have seen so far today.

I felt the same, but I am glad it was you two who finally busted him. Too many thin-skinned ones whining this weekend.
