Grindstone Trimmer.

[Shaggy]

Started sorting some of late father-in-laws things in his shed and come across a Huntington B1 Grindstone Trimmer (whatever one of them is ). At first didn't have a clue what it was but a quick google told me what it was, but not what to do with it :? .

Do I need one? How do I use it? Should I bin it?

It's used to dress the edge of the grinding wheel by removing a little of the worn and possibly clogged abrasive. It's intended to be hooked over the edge of the tool rest with a small clearance between the rotating discs and the grindstone before starting the grinder and lifting the handle to bring the discs into gentle contact with the wheel. Eye protection and a dust mask are essential wear.
They are a bit alarming to use initially because of the noise and dust.

Work well if a bit aggressive. Great if people have been doing things they shouldn't like grinding wood or not dressing the wheel and wearing deep groves etc.

Yes as already said.
I use mine occasionally and it does a great job but pretty messy, go gently or your stone will be rendered smaller very quickly :wink:

Used it last week as it happens because I'd abused wheel shaping a piece of aluminium bar :roll:

Replaced these days by diamond dressers which do a much neater and smoother job without reducing the wheel to nothing.

It's not very often I use my bench grinder so it will be a long time before it gets clogged up or put of shape. I think I'll keep it in the back of a drawer just in case, after all it doesn't take up any room :wink: .

Surely you only remove what needs removing whether using a wheel dresser, a diamond dresser or a devil stone? :?

Exactly!

My warning was to be careful as like most tools you have to learn how to use it. Mine takes only a couple of seconds to dress the stones. It is faster than either the devil stone or diamond tool I have though.

Diamond dresser was a game changer for me. So easy and effortless to take off a tiny amount and get the wheel straight and cutting good again.

Oh yes absolutely but with the aggressive methods you take off too much just by their nature. A fine diamond dresser is much more controllable so you take off the bare minimum.

The wheel type in the OP hacks off a lot of material really quickly and leaves a fairly coarse surface that itself wears faster than the smooth flat surface left by a diamond stick.
