Nice presentation on blade sharpening.

thanks. back when I first got my digital camera and then
being set free from the cost of film I took lots of pictures
of most everything.

I can go into my picture folders and look at the dates of
the pictures and tell when equipment maintenance was done.
while looking at a picture of the 302 motor in the F150 I
noticed a vacuum line disconnected. went back out to the
truck and sure enough the picture did not lie, so I
reconnected the line.


I bought a 6" bench grinder earlier this spring to sharpen my lawn mower
blade.
It was fairly easy on the first side, as in your illustration, ie right side
of the grinder.
(although I hadn't worked out a good solution to hold the angle as you have)
My grinder came with a wire brush on the left side.

that wire brush comes in real handy for removing the
sticky buildup wild onions leave on a blade. every
spring it's always the same tough job of removing that
stuck on wild onion goo.

When I went to sharpen the other side of the blade I...
I...
well I got confused as to how to go about it upside down.

Your grinder appears to have a finer wheel on the left side.
How do you handle sharpening the other side of the blade?

both ends of the blade are sharpened on the right side
wheel of the grinder. with your grinder not running place
one cutting edge of a blade up next to the grinder wheel.
now lift the blade up and rotate the blade from it's center
mounting hole to simulate the same rotation the blade would
make while bolted to the spindle on the mower. after one
full rotation notice how the other cutting edge of the blade
is now just above the same right side grinder wheel.
