While I'm laid up form shoulder surgery, I've been doing some cleaning (more like "detailing") and gettign everything all fine-tuned and pretty for State and Nationals, I discovered an alarming crack on the X Module on our Furious cam....

BOTH X Mods on both cams are cracked in the exact same place:

Obviously, I'll be taking this bow out of the service until it can be rectified.

My wife is shooting a ShadowCat/Elite/Nitrous and a ShadowCat/Elite/Furious was her "back-Up" bow. We are getting her ready for State and Nationals.
Even though this is a most in-opportune time for this to happen,I'm glad I discovered it before anything bad happened.

Anybody seen this failure before?

What concerns me the most is that in looking at the Furious-X cams, there is very little material in this area after all the machining is done. Seems like a high stress area such as this would have more re-reinforcement than less.

I thought I'd jump on the Furious Band-Wagon, but after this I think I'm going to need to stock up on all the Nitrous Cams I can find! Especially with four competitive shooters in the household. We just cant afford to have a bow go down like this.

Upon closer inspection and dis-assembly I found even more worrisome damage to the X-Module.

Apparently there is just not enough material left after machining out the adjustment screw holes.... Whether this caused the "rim" to crack or vice-verse, remains a mystery.

I'm definitely check all the Nitrous-X bows I have for similar damage and would advise all of you to do the same.

Hopefully this is an isolated incident somehow caused by a ham-fisted shop-drone at the local archery shop this bow came from, way back when.


Will need to call Martin in the morning! Do their tech-support folks at least monitor (I understand why they don't post.) the boards here, and might be aware of the issue before I call?

Man, that's some ugly looking pictures there. They're sure to take care of that one for you. I have never seen any cam or module get that bad.

2 of the 4 Scepters I have use the X system. Because Martin insists on drilling both sides of the cams to make them ambidextrous you are left with very little structural integrity. One of my systems is cracked and I've heard the same story from just about everyone I've talked to about the X-system. Frankly I hope Martin is coming up with a re-design because these are way way way to fragile.

I've talked to a Martin staff shooter who has just give up on them. The screws either loosen up on him or he cracks the cam when he tightens them down. been through three sets and has given up.

Well then, this must be some kind of problem with the Furious cam then. The Nitrous cams never seemed to do this, or at least I never heard anything like it-----and mine all had the X system.

Have you let Martin know about it? Sometimes they don't know what's going on out in the shooting world unless it is brought to their attention. Get enough complaints and they'll recognize that maybe things need to be reengineered.

I examined all the Nitrous-X Modules we have, and none show any signs of this failure

This afternoon, I went to the Church, where I store all the bows for my Youth Archery Program I run there, and checked the Furious-X we have... Sure enough the center "web" between the adjustment screw holes is all fooked up. I know it was not like this 6 months ago when we purchased the bow. I'm very critical (some call my hyper vigilant) about inspecting any equipment before putting it in the hands of a child entrusted to my care.
At least the outer string groove has not cracked, yet.

That's 2 for 2 - Not looking too good for the Furious-X.

Sure wish Martin still made the Nitrous cams, I'd gladly exchange all the Furious-X cams I have for Nitrous-X.

Yes it appears to be just the "X" mods.

Yeah, my wife is a real bruiser, same goes for the 14 year old girl at the church that shoots that Scepter. I think that pulling all those 35# @ 27" and shooting those (0.372" O.D.) Victory X-RingerHV (350 spine) shafts with those monster 80gr. stainless steel bullet point tips was too much stress for the X-Mods to handle. Now that I thing about it, the X-Mods never stood a chance against those ladies!!!!

:p :p :p

Gotcha!!!! A bit of sarcasm there, huh? I agree with you. The ladies sure aren't hurting the equipment.

Martin's World Class Support comes through.

Never had a doubt.

This belief is this issue is most likely being cased by over torquing the X-Mod set screws.

When I install the replacements, I'll take the lightest strength loctite and put just a drop on the set-screw threads and allow it to completely dry, then stall the screws with "just enough" torque to seat them well, but not place undue strain in the fragile webbing between the set-screw holes. Hopefully, that will bring final resolution.
