Last week I noticed a surface crack on one side of my old Dawes Galaxy's forks. It could have been there a while and I wouldn't have noticed it. While taking apart the front of the bike so that I could get at the crack to repair it, the whole thing just fell off - you can see from the pics perhaps that it seems to be quite an old crack.
Now, I need to get it repaired. A couple of years ago a rear dropout snapped in half on this same frame and I just got a car mechanic to weld it for me, no problems at all. I spoke to a guy who builds bikes and does a lot of steel work and he said that he couldn't weld this kind of metal, and that it needs to be brazed on instead.
Oh and the handlebar stem is frozen, too so that makes it hard to access the fork on its own.
Here are some pictures. I've not embedded them because they're quite large so that you can see the area clearly.
Ouch, that is NASTY. I wouldn't want to have a go at repairing that, let alone riding the repaired item. Count your blessings that this hasn't had you doing a faceplant and get another fork. They don't need to be that expensive.
The hassle of fixing that as well as cost and then not even knowing if it was truly fixed would keep me from doing it. New fork can be had for 40 bucks. I'd be tearing that bike down completely and giving it a thorough look over too, maybe frame saver it.
It would be way more costly to have a new fork crown brazed onto the old blades and steering tube, than to just get a new fork. Plus, if the crown is that rusty, then the blades are probably compromised as well. You'd have to do it yourself, because a reputable frame builder wouldn't touch it.
