Re: Give Me A Brake! The Update.

I finally have made good progress on designing, producing components and fitting such into a working brake for my Mancha recreation.

Any real machinists should avoid looking too close at the following pictures, strictly self-taught backyard machiner here.

A drum was cobbled together from an existing spare sprocket with homemade spokes and rolled rim. Because this won't fit my lathe I had to grind up on the workstand. This was a one-off and pretty rank in the symmetry of the spokes, mind you the sprocket hub was only for expediency.



Machining the mating surfaces without paying someone...yay!! The handwheel keyway was broached by hand, something I haven't done since highschool.



Test fitting and shaft design workup since the proper Mancha has a screwturned bandbrake application/release to a flywheel mounted on the motor endshaft.



Small "L" object at upper centre is the pin/key for the threaded section cut from a bolt and turned down to fit in the end of the staff. Sure beats threading the end of 1" dia. rod with a handheld die. This also is the key to secure the brakewheel.





Brake band and linkage has been fitted for testing "next fine day".
Elbow has tab projection for mounting a microswitch to cut power as soon as Brake is applied.
Temporary cardboard for lining the band during testing, proper lining won't be applied until the results are in.
Brakes are applied and set in these views, there is sufficient over centre weight in the linkage that may not require the 2 release pullback springs to be fitted.
