shop-made kitchen tool

Metal content: this contribution to the creative culinary craft of
cooking was made by TIG-welding and Cd-free silverbrazing of the
finest stainless steel wire I could find hanging on a nail just below
the oil filter wrench:

While I admire your inventiveness, there's just something "wrong" about using the same tools for both dental care and food prep. It's a nebulous sort of "wrongness," and if called upon to explain it further I'd be hard pressed to do so. It's vaguely like the "wrongness" of dishes containing both chicken and their eggs. One or the other, but not both! :-)

So you are saying it would be wrong to have a chicken and cheese omelette? ;o)

The devil sure finds work for idle hands, Don.
Next time I have to "mix the nearly unmixable" I'll try putting the stuff in the bowl of our little untrasonic humidifier which has been gathering dust in a closet ever since I added central humidification to our HVAC system.

spit and dentifrice with enough
It's not at all unpleasant to
that works better than all competition.
Most toothpastes contain sodium laurel sulphate. Some people, me for one, have problems with getting cold sores from the stuff. When I complained to my dentist about this, he said to loose the toothpaste and rinse with water followed by a final rinse with about a fluid ounce of 10 volume hydrogen peroxide after brushing with just water. The nascent oxygen released byt the H2O2 kills the bacteria that cause plaque and the H2O2 is cheap like borscht.
A month after starting this, I had another appointment to fit a crown. Gums greatly improved and no trace of plaque.
Don, you said, "Awright, so it didn't work real well first try. Nobody said inventing was easy." What did you change for second try? How well did that work?

I didn't. This was just foolin' around -- I was just curious to see what would happen. I'd just replaced the brush so I had an old one to play with. It only took about 10 minutes to cut off the plastic and weld on the bits of wire.
The Soni-Care is a rather ingenious mechanism. There are two small (0.2" x 0.4") NdBoFe supermagnets mounted side by side with about 0.2" between them on a little platform at the end of a lever. They are oppositely poled. The lever is pinned partway up; the pin forms a torsion spring. The brush (or whisk) is at the far end of the lever.
Inside the sealed plastic handle is (I think) an open E-core, facing outward, with a winding on it. It's fed 260 Hz AC from internal elex, which produces alternating lateral force and very small movement of the end of the lever. The lever arm and mechanical resonance (more the latter than the former) magnify the motion on the other end to maybe 1/2" peak-to-peak. My whisk-lever obviously wasn't "tuned" right so I didn't get much motion -- and the internal circuitry is obviously fixed-frequency rather than having its frequency determined by the mechanical resonant frequency.
In truth, it's a great toothbrush but probably wouldn't make a good whisk. A whisk operates in heavy liquids that would provide a lot of viscous damping which would damp the mechanical resonance.
It was fun to play around with, though! Tattoo gun anyone?

this type of need was addressed about 40 years ago with "wand" tipped with a 1/2-3/4" rippled solid beater running several hundred rpm. sorta like a miniature milkshake machine.
they were at all the major fairs for year. worked well, but you could sure make a mess with one. --Loren
