I'm workin' on the DS7 today, and while trying to "persuade" the foot brake lever over to clear the exhaust...


the Fucker snapped off:fireangry:

I pretty much had it where I needed it, but I got greedy and tried for just a little bit more.Slap12
I dropped it off at a welding shop to see if it can be repaired. Repaired would be the preferred solution, since it'll already be bent. I could buy another lever for roughly what I'm paying for the repair, but I would still have to persuade it over also and run the chance of breaking it again.

Keep yer fingers crossed:o

Thankfully, I emerged Victorious!!

The lever repaired just fine. While I was there to pick it up, I had him put the second bend in it to correct the toe pad angle. Got home, bolted everything up... works like a charm :D

I have some more pics of the linkage set-up. But it'll have to wait for the update in the build thread this weekend ;)

Too bad that Austin's Dad's farrier wasn't in the neighborhood with his forge to fix it like Fitty's shifter.

Looks good, though!

Looks like it has some character!

de welded it becomes weaker and will brake again... Order a back up one and have it handy.. Just my 2 cents worth!

I need to hit it with a wire wheel and clean it up, but otherwise I'm happy with it.
I had heard a while back that a properly welded joint will be stronger than the metal around it. Did I hear that wrong, or does that only apply to steel? (which is what we were discussing when I heard that)

Either way, once I find a set of chambers for it I'll be able to put stock levers back on it since they route differently and won't be in the way.

If it was heated properly before welding, it'll be fine. If not preheated, get a spare

Thanks Evil. I didn't watch the guy weld it, but he's been in business there for over 20 years.

It has to do with cooling more than heating.... otherwise known as tempering and annealing....

If allowed to cool to fast after reaching a certain temp... basically a dull red glow the metal becomes extremely hard and brittle. ie the welded area is temped and becomes a brittle spot on either side of the weld. The other way is annealing which is basically heating to a much lower temperature and allowing to cool slowly. This softens the metal and allows it some bend before breaking. When making something such as a knife with a tempered blade, in order to keep the blade from breaking under heavy use, the whole thing is tempered and then annealed from the backside so the edge where the cutting happens is hard and the metal behind it or the "spine" of the knife is actually soft and the combination of the two keeps the blade sharp and from breaking. This free lesson in tempering and annealing has been brought to you by sallie mae student loans and my 7 years of education which I will soon be repaying. :respect:

That applies to steal.. Welded joints can be stronger if done properly .. That shifted is not steel and when welded gets weaker .. Might hold for now but I would search eBay for a spare before it breaks again..

Not only to steel, all metals work that way in one sense or another however most applications of tempering applies to steel (gold, silver, bronze and other precious metals are annealed to be easy to work with in both dentistry and jewelry making). It looks like it is cast steel or what I like to call pot metal, however pot metal doesn't weld well and yes can get weaker. If it is cast aluminum, depending on the alloy, it could also become weaker as the joint might be more rigid and brittle than the rest of the shifter. Point being, I would get a back up as well.
