SamKidney Posted January 13, 2013 Report Share Posted January 13, 2013 Right, I recently purchased another Ice 2. I love the frame, and Im all too aware they're hard to come by now, so I want it to last. My previous one cracked at the bashplate weld ends, so I intend to remove them to eliminate the stress riser. My method would be to use a dremmel, and cut along the inside of the welds just enough to remove the bash mount and its gusset, but not go through the downtube, and then file away the remaing welds until theyre flush with the downtube. Would this be the right way to go about it, or would I encounter any problems? Cheers. Quote Link to comment Share on other sites More sharing options...
customrider-Rhys Posted January 13, 2013 Report Share Posted January 13, 2013 i saw on faceyb that jamie williams just grinded on the welds lightly with a normal grinder until it came off! http://www.facebook.com/photo.php?fbid=4099373567136&set=a.3854370562214.2140887.1366825506&type=1&theater Quote Link to comment Share on other sites More sharing options...
Jake. Posted January 13, 2013 Report Share Posted January 13, 2013 If it was me, I'd keep the gusset and just file/grind off the bit the bolt would usually go into. Quote Link to comment Share on other sites More sharing options...

Surely then you'd just have a random weld that's a stress point but isn't useful in anyway 2 Quote Link to comment Share on other sites More sharing options...

JD™ Posted January 13, 2013 Report Share Posted January 13, 2013 Yea that's the right way to do it, same way I smoothed everything off the zoot. As you're filing, you'll get to a point where it looks like you're going through the frame - you're not, that's just the hole in the weld. Don't freak out like I did!

Jake. Posted January 13, 2013 Report Share Posted January 13, 2013 Surely then you'd just have a random weld that's a stress point but isn't useful in anyway Hmm, I thought it would be stronger if you had an extra plate of metal there?

williams Posted January 13, 2013 Report Share Posted January 13, 2013 Hmm, I thought it would be stronger if you had an extra plate of metal there? Just a thought Nope, it creates a stress point.

Pugson Posted January 13, 2013 Report Share Posted January 13, 2013 How could it possibly create a stress point if you're not applying a force to it. If u just didn't put a bash plate on it would be no worse than if you ground it off. It just won't be as aesthetically pleasing. 1 Quote Link to comment Share on other sites More sharing options...

Pugson Posted January 13, 2013 Report Share Posted January 13, 2013 im sorry but this is just ridiculous, if your not landing on it because you havent got the bash plate on, you havent got the applied force on the underside of the downtube. how have you created a stress point?

trials hoe Posted January 13, 2013 Report Share Posted January 13, 2013 quite the opposite. doesn't it affect the frame in the same way 4 bolt mounts affect forks? ie. a place for crack to start. 1 Quote Link to comment Share on other sites More sharing options...
SamKidney Posted January 13, 2013 Author Report Share Posted January 13, 2013 (edited) Exactly. Ive cracked 4 bolt forks when running a disc.. I never ran a bashplate on my previous Ice, and that cracked there, and my Echo cracked on the two weld ends of its headtube gusset.

Jake. Posted January 13, 2013 Report Share Posted January 13, 2013 quite the opposite. You stated this already, no need to state again im sorry but this is just ridiculous, if your not landing on it because you havent got the bash plate on, you havent got the applied force on the underside of the downtube. how have you created a stress point? If you hit the bit that sticks out on a bash mount, it causes a higher chance to crack/snap due to a much smaller pressure area. Quote Link to comment Share on other sites More sharing options...
SamKidney Posted January 13, 2013 Author Report Share Posted January 13, 2013 (edited) It's being whipped off tomorrow. As for the stress point, it is exactly like how a fork breaks. The stress a fork goes through ideally needs to be dissipated as equally as possible. The 4 bolt mounts on a rear of a fork interrupt this dissipation, and the stress is diverted to this point, causing a weak point. I.e, the stress riser/point. Thats what I can make sense out of it. An example of this would be try-all having a line of weld from the mounts up the leg up to the crown on their forks in an effort to evenly spread this stress. I dont know if it works, someone who's ran both examples would have to comment. Disc forks tend to last far longer than their 4 bolt counter parts because they dont have the mounts welded to the back of the legs. Im hoping, in applying the theory to my frame and removing the mount, I eliminate its weak point and prolong its lifespan.

I think i'd rather have my forks snap at the 4 bolt mounts after a few months than the steerer to fly off later on Quote Link to comment Share on other sites More sharing options...

Either snap has the same outcome haha Quote Link to comment Share on other sites More sharing options...
chris_trials Posted January 13, 2013 Report Share Posted January 13, 2013 Actually, the weld doesn't create a stress point. If anything it adds strength, however, if you were to file/grind the weld so that it sits flush with the frame then that would create a stress point where you've thinned out the frame. All I would do is remove the main body of the mount and leave the welds alone 2 Quote Link to comment Share on other sites More sharing options...
bing Posted January 13, 2013 Report Share Posted January 13, 2013 Sam, you are reading way too much into this. frames break, it's a fact of life. the damage on your old one was more than likely already done. cut the bolt hole thing off, smooth it off and leave it at that. mine has that, and it's not cracked in the 3 years me or josh barker had it 2 Quote Link to comment Share on other sites More sharing options...
SamKidney Posted January 13, 2013 Author Report Share Posted January 13, 2013 It wouldnt be thinning the frames tubing. It would be filed so the weld is removed, with as small amount of tubing as possible. Like I said, I'll be going ahead anyway. If it lasts longer, great. If not, then it can only last as long as it would with it being there if the stress riser hasn't been removed. Sam, you are reading way too much into this. frames break, it's a fact of life. the damage on your old one was more than likely already done. cut the bolt hole thing off, smooth it off and leave it at that. mine has that, and it's not cracked in the 3 years me or josh barker had it Its something Im genuinely interested in, and dont mind finding out about. Im all too aware that frames break, I went through 5 last year. Quote Link to comment Share on other sites More sharing options...
Rockman Posted January 13, 2013 Report Share Posted January 13, 2013 Surely the frame was made with the mounts on, welded and everything then heat treated.. So it'll already be weakend, and removing it will make no difference? We need Rob Leech to see this. Quote Link to comment Share on other sites More sharing options...
BradJohnson Posted January 13, 2013 Report Share Posted January 13, 2013 I'd use a hack saw to cut off the thick, then do the rest with a dremmel and/or file. That way it eliminates the chances of slipping with a grinder and taking chunks out of bits you really shouldn't. Quote Link to comment Share on other sites More sharing options...
SamKidney Posted January 14, 2013 Author Report Share Posted January 14, 2013 (edited) Well, its done. Ground the welds down until I could just see the divide where the weld met the gusset, lifted it out, then filed the remaining welds down. All smooth.
