Forgive the clumsiness-I'm doing it one handed-not recommended!

Eric, 
You need to find a hand-cranked grinder...
Or one driven by foot oedals.

Waterwheels and windmills are also acceptable...
 
Maybe, just maybe, a mandrel driven from a hit-and-miss engine via a flat
leather belt would get the nod.

Hey Eric

I have a large vintage 2 x 17ish wheel with crankshaft and all sitting 
in the garage I can sell for a good price! ;-)

Eric & GG's,

You've heard of "flattening the back?"  Applying a round abrasive wheel to the
back of a blade, freehand, cannot be good for flatness.

Deburring ? 

Surely a deburring wheel would be leather, or a stitched mop well charged with a
medium  coarse grade of abrasive - enough to manage a serous strop and remove
the burr.  The video sounds like a conventional grinding wheel contacting the
surface.
 

Richard Wilson
whose only burrs these days are the sort that a strop removes, and leaves edges
too sharp to feel.

Eric,

It looks to me like a good gentil-ish cleanup before a final flattening. 

Nice grinder! 

Watching the loose jacket close to the spinning grinding wheel kinda givin’ me
the willies.  Careful. Don’t want that spinning beast wadded up in your armpit.

A deburring wheel is quite unlike a grinding wheel.  It is composed of a fibrous
material, presumably in a slurry of  grit which is then compressed into a wheel.

While I have never measured it's "grinding ability" I have been using these for
years and never experienced any "gouging" as one would expect from a grinding
wheel. From my metalwork experience, I suspect the clean-up passes in that video
don't even remove more than .0001

Ah, that’s OK then.  Now I’ve learnt something, and in our best tradition of
tool demonstration and description - I want one!
