I have a hand cranked bench grinder. it's just right for that kind of thing. it turns slow enough to be able to grind close to the edge without worrying about taking too much metal or overheating. besides, it's a hand tool ;)

I must say that I haven't experienced the virtues of the Washita yet, despite trying. Mine is really too slow, or I do something wrong which is very well possible. At the moment I prefer a manmade oilstone fro the coarse step combined with an Arkansas translucent and a strop.

Go with whatever works, I guess. I do grind more often with a washita than I would with some other stones, and I have had a bunch to pick from and generally go with the fastest ones (which tend to have a lot of mottling). Still, a grind is good for 4 solid honings, at least, and since the grind is only a little at a time, it's quick.

Bridger; you also use a milling machine. What's the issue with not using a powered bench grinder . !!

Stewie, what has gotten into you lately? I don't think Bridger's comment is one intended for a debate contest.

I have never come across a nice hand cranked grinder in the wild, or i might have one instead of the uber expensive (not to some, but to me) baldor with a pair of wheels, one being cbn. Not that the baldor is functionally any better than the $40 ryobi grinder with gray wheels that preceded it, but at least it runs without needing to be clamped down.
 
Hand cranked doesn't make sense to me - unless you've got somebody cranking it for you. You only get out what you put in so why not apply your energy direct to a flat stone? Also it leaves you with one hand to hold the blade. I suspect these are the reasons they are not so common. I've never tried one, I could be wrong.

But a flywheel would help. The obvious design would be something like the potters kick wheel, then you are using your feet as well as your hands.
Wouldn't be difficult to bodge up something like this:

You are all missing the point. Bridger has given it in his post. It's about control, being able to creep up to the very edge of the blade without removing the tip. When you get close it's simply a matter of slowing the wheel. Not overheating the blade. Hard to have such control with a powered grinder. It has a great many different speeds, decided by the operator. There's a polished band of steel left by the polishing stone. The idea is that you remove all but the very edge of this. One hand, two hand, it doesn't matter. It's just another skill, doesn't take long.

They don't even have a tool rest. None of them do. True freehand sharpening. The usual hand crank is a breeze in comparison.
 
My first student was very Keen on all things Krenov.

He found a nice hand grinder, built a JK type rest and soon became very proficient with it.

Charnwood Forest? Isn't that where Sir David Attenborough found his first fossil, as a youth? :?:

What like is it as a huntin' ground for landscape painters Lurker? :mrgreen:

I'm trying a ceramic sharpening stone, on a whim!

Cheers
:D

I have an old electrified sewing machine still with its foot treadle. That would be good for a 'goer', I could convert my Tormek? (hammer)

Hi John
very old (even in fossil terms) and rare fossils have been found in the forest but not by DA.
The scenery is quite spectacular for a small area, lots of Bluebells at the moment in the woods.
You could tuck in some wood related stuff too like a visit to Charnwood tools showroom and a couple of hours at Stoneywell cottage where there is some wonderful furniture made by Gimson
If you come next Friday (20th) there is also the David Stanley auction :lol:

Thanks Lurker. Me and my wallet would be well-served by keeping clear of Charnwood Tools; they have a dinky 8" table saw, that would fit my shop, and the reviews are tolerable. I couldn't get that under the radar! Sadder though is I can't go anywhere special; the Doc won't pass me as fit to drive after a suspected 'mini-stroke', on the grounds my BP is too high. He's ramped up the rampiril!

It looks like living on rabbit food for a while, to get some weight off! :x


Cheers.

no issue at all. I also have some 6 or 8 powered bench grinders, depending how you define bench grinder, and I use them. but for what DW was describing, quick frequent light grinding of the primary bevel to take the load off of the honing process, the hand cranked grinder hits a sweet spot of slow variable speed, no messing around with water cooled wheels and minimal throwing grit around the shop. if I'm doing something involving much metal removal I'll use a powered machine.

Most treadle grinders are of course large sandstone jobs with a simple pitman arrangement; pretty much time honoured tool.

https://www.youtube.com/watch?v=9nx2Ut7K8Is

But there was the famous (depending on the circles you move in) Heyden AllBall treadle grinder.

https://www.youtube.com/watch?v=ErMs--ZJAqo

It works via a recirculating ball bearing drive, very complex, but absurdly robust and reliable.

It almost defeats the object of a hand (human powered) grinder, because in adverts it claims to run the grindstone at the manufacturers full rated speeds (which might leads to more heat). With enough RPM the grindstone is its own flywheel, of course.

My local bike shop owns and uses one.

I suspect that the main reason for the highish prices paid for genuine Charnley Forest stones today is the value put on then by collectors rather than users.

But .... whatever.

Sorry wrong suspicion. Theere are few collectors but not as many as straight razor honers. Those straight razor guys love them (yes i am one of the as well as collector with deeper interest in specifficaly this type of hone) and that is what drew prices up for good stones. However there are now many which are not good enough for razors.

Fair enough! I suspected wrongly. Thanks for the correction.
