Been working on a new pulley and brake system for a SB 9A. The brake will be used for emergency stop and for preventing coasting when doing some tight to shoulder or metric threading. I haven't built the step bar, or brought in the contactor to disable the motor yet, but finally finished getting the pulley and bracket built. Because I don't have the original plate from the lathe that allowed side to side, the motor requires the pulley be pushed farther out on the shaft than I care for. Ran the cable sleeve, but haven't run the inner. That will wait until I start on the pedal.
The brake seems to work well even without the pedal. After the pics I went back and chamfered all the holes in the rotor. Really crappy work on the brakes. I checked the hole pattern between the caliper mounts (bought 2) , they also didn't match (like the rotors). This is super low budget low quality hardware. I hope it doesn't come back to bite me.
I'll trim the bracket at the back before I paint it, it needs to be rounded off to match the boss it's attached to.
covid's still affecting me so I really don't get much time to work on it. I am only good for a short time.. Covid sucks.
