Classic & Vintage - Hotrodding Canti brakes - Hey Luker

Reading through another thread, I came across this Luker quote:

"The canti posts for the universal 61's were a fairly standard way to hotrod the performance of the brakes, and I have seen that detail on several bikes of the '60's."

I have a bagful of cantis laying around and was considering putting them on a dirt-track-capable, sorta-cyclocross, sorta-rivendell build of an old Schwinn Super Sport. How does one hop up such brakes.

i feel like this is referring to using canti mounts for center pull brakes? The placement is specific to this though.

here is an example

There was a NOS Mafac Raid brakeset on eBay recently that came with the mounting posts, ready to be brazed on.

I just found it:

I'm pretty sure that you could build your own setup, using standard cantilever posts. As singleDebile sez, the post placement is unique to the cantilever brake you are using; cantilevers are not mounted in the same place. They really do stiffen the brake, allow for better modulation, and take care of most of that nasty squeal; and they are cooler than heck.

Unless you have a body of experience with a torch, I gotta recommend not learning on brake parts, though. I was rooting through a bolt jar today and came across a lone cantilever post...one I brazed on a Ross clear back in 1981. It is the last remaining part of that bike. It was the part that I retrieved after my brazing let go on a big downhill.
