clamshell catches

Here's an imperial one:

'Might be a bit long, and a bit loose in the holes.

Ok, the binder pins have arrived.

See photo. I have replaced the missing long pin on the catch on the left.
Compare the original circlip pin (fitted to the catch on the right) with the binder pin and binder pin fastener/bolt.
The binder pin does the job, and it's solid metal all the way to the threaded part.
I chose 5mm x 30mm.
From this listing:

The only worry would be it unscrewing itself. So some good quality thread lock or maybe even epoxy might be a good idea?
In the case of a used catch, after the parts have been refurbished, obviously.

Looks good. So these are for the ones with the circlips and not the central one which seems to be riveted in on my catches.

Just some decent thread lock would do the job I would have thought.

Yes, that's right.
I don't need to replace the short one myself. The end of the short one is crimped as OE.
The overall width of the fitted OE crimped pin is 25.5mm.
The depth of the threaded (hollow) part of the binder pin that I have used is 6mm approx.
So the same pin might possibly be used for the shorter crimped pin. As long as it's possible to crimp/crush the hollow end?

You'd need something like a brake line flaring tool to crimp the short pin.
Some sort of tooling at least? Rather than just squash it in the vice.

I have a flaring tool - good idea. I might give it a go. Nothing to loose really.

Started to do this yesterday. Dismantling and cutting the back plates down for the levers. On the first diagrams shown on the first page of this thread the extra hole position looks like you would need to grind the small post/stop from the base. It's not shown on the diagrams at all. But Andy's pictures show the hole higher up and the post is still there.

Just so I'm clear. Do I leave the post in place or grind it off?

Cheers.

Yes a very very little light "splash" of blu Thread lock and if possible replace the bolt with an button allen bolt ( could be easier to unlock compare to a screwdriver ?)
