Tom mentioned a while back he uses a washing machine centrifuge.
Some front load washing machines spin at 1200-1500 RPM.
About twice the speed of uprights.

The secret in making front load washers work is in keeping the
containers in place when it's not spinning.
Voila... my old sleeping bag (don't use down-filled bag... too fluffy;
the old, heavy, 3lb polyester filled ones are just right).
Fold lengthwise in thirds, then tightly roll, tie, stuff into the drum
(make sure the metal zipper is not touching the glass window of the
washer; the zipper on mine is tucked in the inside fold), then untie and
allow to expand to fill the empty space.

Fill the bottles to the brim and cap tightly.

Fill ALL open positions in the drum circumference so that the load won't
shift during spin ramp-up and ramp-down. Balancing the load is very
important. Put tightly capped empty bottles in all 'unused' positions
(keeps 'em from collapsing when full ones press against 'em).

Capacity: 48 ounces to about 5 gallons (Nine half gallon PET plastic
juice containers, plus three 16-22 oz PET plastic drink bottles).

Pros:
Four spin cycles almost completely clears gross lees from 5 gallons of
wine (great for noveau-style wines, where ya don't wanna wait months for
gravity settling).
You can go from milky haze gross lees to clear wine in an hour (three
centrifuge/racking cycles).
Undetectable vibration during spin.

Cons:
The lees are compacted onto one side of the plastic bottle, which means
some lees get resuspended into solution while pouring out the wine after
spin [second generation will use cut foam pockets so the bottles stand
radially... compacting the lees into the bottom of the bottles. This
will reduce the load capacity a bit, but hey, the motor does get kinda
warm after a few spin cycles with 5 gallons load.]
My washing machine doesn't have a 'spin only' cycle (and I have to turn
the water off at the spigot to keep it from injecting water during
spin). [Guess what I'm doing when the warranty is up.]

The best part? "Honey, what are you doing?" (My wife's precious
puzzled remark as I'm experimenting with the best way to fold/insert the
sleeping bag into the drum).

P.S. While googling (+spin +rpm +centrifuge +wine) I came across a
funny blog titled "Things I wish I had in my kitchen". Hope you enjoy
it as much as I did.
