Grade of steel for bike rear dropouts?

Hi all

Does anyone know from what grade of steel bike rear dropouts are made? I have to make and braze on my own

you can cut them out of plate but it will have the same problem as your current dropouts. The Axle in a geared hub naturally wants to rotate and if free to do so will chew away at the metal. A cast dropout or something replaceable would be your best bet in the long term.

Ceeway (http://www.framebuilding.com) have a huge range. Or have a look and some of the Paragon works dropouts. www.td5.org

You can use the anti rotate washers that shimano and the like sell
To keep everything in place

If you made your own you could make a screw on replaceable section on them where they wear. I think most originals are drop forged.

Many thanks for the advice guys.

I have anti-rotation washers that came with the SRAM hub (geared and braking) - hence the new direction for the slot. However, I'm worried that plate won't be hard enough on a torqued-up tandem, even for them.

Ceeway look promising (great link) and I'll check out Ragley and Nukeproof as well tomorrow.

Cheers

Forgot to say - that was my idea too, until I realised the middle chainstay join had cracked (see photo), the whole structure was weak and I should replace the whole thing
