Surplus Center has these wonderful motors that I would like to use for a wire-brushing operation. (imagine that) They have a 1/2" dia. nine-tooth splined shaft 1/2" long. Have any ideas how to mount an arbor on that shaft?
I machined a broach to fit a pulley to an ANSI-splined hydraulic pump shaft. While it worked, the required effort was only justifiable as toolmaking practice. The difficult part was grinding a lathe bit cutter to the 30 degree involute(?) groove shape.
Afterwards I found this tilting vise that made angular fly cutter grinding much easier.
It shifts the problem from grinding the cutter to measuring it.
I think it could help grind lathe bits to Law-approximation gear cutters using conical stones to achieve the correct diameter easily, with automatic relief below the edge. jsw
Damn! I didn't notice that, thanks. That's a deal killer. I need to get two brushing stations operational in less than a week. Without an off-shelf solution and the intermittent DS, I'll just buy from Grainger.
1) Bore to just larger than the diameter at the root of the spline.
2) Use the lathe as a shaper and index off the bull gear (or a real index head an real shaper if available) and cut a matching spline.
3) slit down the middle of the thin area of each spline.
4) Clamp around this to grip the motor's shaft as well as possible. (probably add bearing-mount LocTite for extra grip.)
Or (depends on length of arbor -- for a long one)
1&2) As above.
3) Mount the wire brush between two sealed bearings, and mount bearings to the face of the motor.
Probably other options as well. Just what came to mind on reading your question.
WELLLLLL, I might. I'll just buy Grainger after I call the local rewinder...just in case he has 2 of something laying around. I have to clean rust from 4,500 lbs of flat wire for a NY company that was flooded by Sandy. The wire is on 200 lb spools. I'll run the wire from spool to spool and wire brush the top and bottom in between. We are good as handling flat wire and have the tricks to spooling and unspooling. I'll try 5 wires at a time.
