Isn't it a tad unusual to have the grinding wheel axis of rotation
perpendicular to the table on a surface grinder? (Unless it is
intended to grind vertical surfaces, that is...)

Relatively common actually Tony, fitted with a cup wheel.  Quite often
on this type of grinder the grinding head swings round instead of the
job being passed under it.  More useful for large flat areas, as
obviously it covers more area at a time than a more traditional type
of surface grinder.

OK - that makes sense.

and can't really make edges or useless trying to dress a profile onto the
wheel. Mostly used for resharpening punches.
Don't you call that a Blanchard grinder?

No, I call a Blanchard Grinder one with the name "Blanchard" cast in to it
that is 4m tall, uses a 1m diameter wheel and a 2m diameter rotary table.

Other than that, they are quite similar :-)

Tony,
         Model Engineering Services ie the suppliers of the Quorn and
Kennet castings also supplied castings for a small 'Blanchard' type
grinder.

Actually, mine has a 'fixed' head and the work table works to and fro
with a ratchet.

This suggests that I should put a new wheel on it and flog it on E-Bay
as it is a nice thing to flatten castings prior to machining.

I believe that JS has a something similar.
Earlier, another correspondent and I tried to get more info as we had
identical machines but no drawings or manuals.

Interesting tool, though
