I bought it with hose clips - he had them on it for use on the trainer.

trogedon, Jun 11, 5:17pm
Under engineered sadly. No impact - original carbon forks and wheels.

I did too and thought it quite nasty and for no real reason.

trogedon, Jun 11, 5:18pm
Ok, I'll go for 2/ or 3/. Thanks.

not sure if there is enough room to sweat a band around the outside.
you need to reinforce it some how otherwise even if you weld it, heat treat etc, its still going to fail due to poor design.

tweake, Jun 11, 5:28pm
quick question
is there any sign of rust between the frame and the steel bushing?

trogedon, Jun 11, 5:29pm
That seems reasonable and I'd be riding along looking at it wondering when, not if it would fail.

Meh piece of wee wees to a decent engineer like Bruce from Brugar
turned interference alloy sleeve welded on to outside. shaped to fit.

Sorry for repeating the obvious -shesh! Sorry for not paying attention
Ive welded my downhill bike frames lots
Thats a speciaized big hit at the head set and the bottom bracket
I can weld it for you , ive got an old ships clock that needs a once over - keen for a deal?

tygertung, Jun 12, 7:48pm
Could weld it, and then machine up some bands with an interference fit to tap on the outside, but the thing is, with all that effort, it might be easier and cheaper to find a replacement frame.

try Machine Part Welding in Penrose,got an aluminium repaired there.Was welded etc.

Fraser Cars Beachhaven. They know what they are doing when it comes to metal and they have TIG.

2nd that - I've taken welding jobs to them that have been in my opinion quite tricky - cast and aluminium etc and it is never a problem .

never heard of an alloy boat builder without at least 1 tig, did you offer to supply the tap to re-tap the inside thread after welding, can of worm no one will go near that unfortunately, that tube is so thin there will be defiantly some distortion

Id say a Aluminium wheel repairer or a specialised welder shop for the welding.
But its going to need reinforced & some sort of sleeve push fitted & welded on to each end.

tygertung, Jun 16, 8:26am
There shouldn't be any thread, the bearing cups just slide in there.

trogedon, Jul 1, 6:18pm
Thanks for the ideas on this guys. I ended up taking some good parts off it and selling it.

I still could have welded it, its ashame, the ships clock I have was working good so probably an easy fix, came out of a ship that sunk in the wellington Harbour

I would say a new front pipe needs to be machined so it can handle the forces and then welded to the frame like it originally was meaning it will need repaint the neck after also.
My racer bike is from about 1982 or so and its like 8kg or something i can lift it with one hand and its made full of steel pipe I recon its one of them 20.000 deutchmark triathlon bikes or something . i got it in 2003 for free its got glue'on tyres they want 180 doller a tyre in nz i found them for 40 bux in europe and got me few to keep me going. as i sure as hell dont pay more then car tyre for a push bike tyre.

trogedon, Jul 2, 10:59am
Yes, it's seem it would be more complicated than just welding. Your bike is cool. They did and do some amazing steel frame bikes.

trogedon, Jul 2, 11:00am
Sorry for the late reply. Thanks for the offer to weld in exchange for doing your clock. I'd be happy to look at your clock for free if you're out West.

There's a few other mid 2000s Scott frames on the net with cracked head tubes. May have been a thing with them.

Aluminium under cyclic loads (no pun intended) work hardens and cracks. No getting around it. If it's cracking there it will be about to be cracking elsewhere it gets loaded. Like an aircraft part, a finite lifespan.

ronaldo8, Jul 3, 6:42pm
50% clueless guff.
Heat treating isn't tempering, its stress relieving.

caleb.b, Jul 16, 2:54am
Yep, exactly, likely to crack again after welding due to weld stress. The joy of these fancy alloys finding their way into everyday items
