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.
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.
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.
Measure the diameter of the spline.
turn and thread a shaft to fit hole in wire brush.
drill ID of reverse end of threaded portion, and then bore to size of
diameter of above spline .000/+.003
Drill and tap for (2) setscrews over ID bore
Install on splined shaft. Use hammer if necessary to drive to full
Install (2) setscrews with Loctite (blue)
Turn on motor and use wire brush
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.
