I know this has been done to death but I believe I just found a way to do it. What I did was take an old sprocket, chopped it up and drilled 2 holes in it to mount an arm / lever. the brake arm is on the other side. It seems when this sprocket / arm moves backwards it will stop the wheel with a fair amount of force so I'm working up something that will pull it back. I have a cable and some bolts here. I'm gonna rig up something to attach the cable end to. thinking of using an old V brake arm :p

now I know I could save myself a headache and buy a Sturmey-Archer XFD or something but I wanna have some fun with this.

There was a thread about it a few years ago on ratrodbikes.com. I believe he connected the torque arm to the fork as you have. He somehow permanently mounted a piece of bike chain to the sprocket. The brake cable attached to the piece of chain to actuate the brake. I may try to use a coaster on the front myself.

I saw that too! I just got down screwing around with the brake. seems like mine will work without a chain so far. I rotated it the same way a cable would pull it again and it still stops. I'm going to do a ground test once I'm finished. hopefully I don't go over the bars if it works out. if it does a gradual but fast stop I'll consider putting it on a motorbike
