I have a rear crinkle hub that has a slight gap between the two halves where they come together. It seems one or more of the rivets may have loosened. They come back together when clamped. I was thinking of drilling between the two halves at the joint in 3 or 4 spots with a 3/8" drill bit almost down to the inner sleeve, then welding in the hole to fix the two pieces together. Anyone think of any reason why I should not do this?

The wheel is already apart. The hub is not about to fall apart. The gap is really minor and would probably be ok as is but would be better repaired of course. We're talking a couple of thou. in one spot only.

As I recall there are three versions of the crinkle hub, plunger type, pre unit swingarm type and the later threaded speedo drive type. Many vendors do not know what they are selling.

The roadside repairs make for the best post ride stories.

I'm not sure what type of hub I have. It has flush rivets and a threaded bearing retaining ring on one side only. The hollow spindle looks different to what is in the manual. The bike is a plunger GS but a bit of a bitsa so who knows what the hub is from.
