Braze or TIG this part

I am going to have the reaction arm anchor moved from the top of the CS to the bottom. Currently it is brazed on. Once removed, could it be TIG welded on? Frame material is 4130.

Either way should work just fine.

I'd braze it (because that's what i do better). But understand that the reaction arm's forces will try to open up the slot with the bit on the underside of the stay. So beef up it's thickness or don't have a slot, just a tab with a hole through it and pull the bolt out for wheel removal. Andy.

That may give you a little trouble if you are trying to stop from going backwards!

Or saw it off and add a coaster brake typestrap// nutted hub is not QR anyhow..
<[I'm using a ball detent pin, on the reaction strut of my S-A Drum brakes , now for 20 years .

so I only need the 15mm spanner to pull the wheel.. after pulling the ring, that pulls the pin.

the Arai drum unscrews when you brake going backwards , ..
but for it being quite tightened from stopping forward motion.

When Arai brakes were available they came with such a brake arm strap. A very well made one. Since so many of these brakes were sourced through the builder of tandems most consumers never got this strap. Andy.
