Probably a bit OTT for d-i-y but in the short time each day between
sitting stationary on the M25 I've been using a large mower. It has a
horizontal shaft which revs at 1000 rpm and has a total of 60 fixed
teeth in 6 rows, within a width of 2.3 metres.
As the teeth wear unevenly, and are expensive, I replace them one at a
time but this causes the rotor to go out of balance. I can try to
remedy this by swapping part worn and new teeth around the rotor but I
would like to better dynamically balance the rotor by having an
insight into where the heavy spots are.
I'm guessing a dynamic wheel balancing machine works by sensing the
out of balance force, but how?
Would an accelerometer clamped to the mower, whilst it's suspended off
the ground, and linked to fire a strobe be a feasible, cheap, means of
identifying where to change a light tooth for a heavy one, or vice
