Someone on here might have a need for the hardware/linkages. Or...you could have fun destroying it :devil:Appendage said:I'm done with my MkIII. Even if I were able to find another replacement rear triangle, it would only be a matter of time before it would break. I'm going to harvest the parts and put them on something else.
So...what to do with the front triangle and all the pivot hardware/bearings/links? Does this stuff have any value to anyone? I would think there would be plenty of this stuff available from guys in my situation.
What to do with a MkIII carcass?

you looking to sell is complete?? let me know
Naw.
Nope. Gonna move the parts to another frame.cth978 said:you looking to sell is complete?? let me know
no i mean as in a complete frame. like with bearings etc. no actual parts. minus the rear triangle
I bet you could get some money for it even though it's broken. I'm sure there is someone out there who could weld it back and re-use it. I have some extra carbon fiber laying around, I wonder if the broken part of the triangle can be wrapped up like a cast.....It seems like it woud'nt be too difficult. Do you have any pics of the break?
put a price on the linkage and bolts and see what happens. i'd be interested for the right price, but i'm not sure what that price is at the moment.

This must stop. No way ever will placing another material over a fatigued and failed material, be they the same or dissimilar ever be considered a fix. Only a strengthening to a perfect foundatation, but not a patch.
And weaving Carbon Fiber around it--laughable and absolutely ridiculous. If you even mean lugging the frame and making carbon fiber stilts it is nothing which you would be able to rely upon. The metal would just fail at the next closest spot. Those tubes are not butted for the stresses of a different tensile-strength joiner.
I don't fault your want for a ride, but these are some very unsafe measures being considered.
What I hear you saying is...
Uncle, are you saying that repairs of cracked frames are bogus? I don't know anything about metallurgy or welding, but there are shops out there that will (in some cases) repair a cracked frame. That said, just looking at the location of the crack, it seems like a tough place to weld, and some form of gusset would be in order to distribute some of the stress. Then there's heat treating and paint/powder coating. Not gonna be cheap even if it's possible. Still, if someone could come up with a decent fix, there's plenty of customers...Uncle Jemima said:This must stop.

Not exactly. What I read was the desire to have someone wrap the cracked metal with Carbon. Still with the cracked metal underneath it seemed. Even with inference that the failed union of tubing would be removed and Carbon Fiber put into the void via traditional means would not be feasible. Not be feasible because of cost. The only true way to repair a failed tube like on the Mark III is to replace the entire length of tubing. And I do not see that as being done proactively, it would be best to fabricate a entirely different back-half but that will introduce all the cost and mock-up time which is what 'DD' and yourself seem to be wanting to avoid. Understandable.Appendage said:Uncle, are you saying that repairs of cracked frames are bogus?

Not feasible
Yeah, I dunno, I'd be will to spend money on a new swingarm if I had some confidence that wouldn't break. Too bad about all this, the MkIII was great in concept but seriously flawed in execution.Uncle Jemima said:...it would be best to fabricate a entirely different back-half but that will introduce all the cost and mock-up time which is what 'DD' and yourself seem to be wanting to avoid.

I would get it welded, gussetted, other welds inspected and gussetted, and then heattreated.
That's Plan B
That's Plan B. Plan A is to see if I can get another frame altogether for a comparable price. If I do get it fixed, I'll be sure to post all about it.

What size frame? What year is it?
It looks like he's willing to work on MTB frames, but specializes in BMX. I might give him a try when the rear triangle on my MkIII breaks.Uncle Jemima said:
Thanks for posting the link.
05 frame. Size large.

Just throw some magic putty on that bad boy. RIP Billy Mays......
