Now can I quallify as a Home Shop machinist?
He needed his Pickup Truck, and don'tcha know it rt frt caliper was seized.

E R time I, got it all appart, while he went for calipurs, and I thought "why not",
Let's try a little trick, as he doesn't have time for rotor-work.

7" side grinder to the rusted inner face, where pads don't make contact.
Bout 180 rpm latter I went to the outter edges.
.003 T I R... Offset from the .003 T I R of the worn in area.
Not bad for eYe-bAll work.

Thanks, went for Jalepino Poppers with it, and pads seated in Pronto.
Next time it's my car, I'll try a 100% clean-up just for Kiks.

I mounted a H.F. 6" cross slide vice, and clamped a air die grinder in the vice,
with a stone, 1/4 h.p. motor on a board sitting on the ground, v-belt looped around rotor.

Good post OH - many thanks.

In its simplest form a Blanchard grinder has segmental insert grinder inserts and it has a vertical spindle with the work rotating on a magnetised chuck.

The spindle is slightly off-set from vertical to the chuck.

The Blanchard grinder is in effect a grinder version of a normal fly cutter - which can cut a very accurate flat face - simple as that.

I would go with you up to that statement, which I think is misleading.

A flycutter is essentially a single point cutter. A Blanchard grinder effectively has many cutters which are arranged in a plane . The cutting action is quite different and this matters.

Maybe he meant "The Blanchard grinder is in effect a grinder version of a normal face-mill".

But not realy either.
Blanchard work done correctly settles downward and cuts uniformly allong the entire
faces of the stones.

A face mill cuts only "in-plane" advancing latterally.
Blanchard grinding is A Bird all it's Own.

I take your point Bill as it I did say it was "effectively" as opposed to - saying - "actually".

Much the same was as an end mill cutting on its end is effectively a multi-toothed fly-cutter.
