Gus, Im in Oz. Retailers are Hare & Forbes, Total Tools or CarbaTec.
Mine is a Tormek but there are others available. It will sharpen everything from a pin to an axe & various jigs are available. Would make an interesting shop exercise making the jigs. I have had mine for over 30 years - purchased before I got into hobby metal machining, & in that time I am on to my third stone [ used commercially ] so not a cost consideration. I would reccomend them to anyone. Not cheap but my favourite tool & has saved a lot of anxt over the years. I always know my edge tools are sharp, & that makes fo easy working.

I could say you guys are a bad influence . But that would not really be fair. I have thought about a wet stone grinder for a long time . and this thread has inspired me to order one. I ordered the Scheppach 10'' Wet Grinder/Sharpener System from sears.com . seemed to be the best overall value . Grizzly has a copy that is $30 dollars cheaper but when you add shipping and a tool clamp(included in the one I purchased) the over all cost would be higher so I am getting a German product cheaper than a Chinese one, go figure. My intent for this is more for knives and other edges but I expert I will use it for lathe and shaper tools as well.

So for $212 delivered including tax and shipping to my house (38 lb package ) do not think it too bad.

Olli: Thanks for the info do not remember seeing the Scheppach brand before. And now have one on the way.

we do not want to get it that hot. like others have said hold in your bear hand when it start to get warm cool the tool.

Which raises the question of how are people holding HSS bits when they are getting them red hot on the grinder?
Gloves should never be worn when using a pedestal grinder or similar, as the fabric or leather of the glove can get caught between the wheel and the tool rest and drag your fingers into the wheel.

Grind bare handed and you will have no trouble with overheated HSS as it will require dipping in water regularly just to hold the stuff.

I use a 2" x 48" belt grinder with aluminum oxide grit to sharpen my HSS bits. I take it slow and dip the tool in water frequently but the belt grinder cuts pretty fast. A lot easier to set the angle against a flat belt surface than a curved wheel.

Gus I believe Lenard is using one of these he will have to tell you the model.
the Japaneses water stones are dear at $250 each but with care should out last the operator.

IMHO Sharpening supplies.com offer good value and ships fast htis is the place I purchased my Norton white stones.

Tormek Sharpenter
This one pictured is about $380 plus shipping.

Hi Tin,
Went shopping for Sashimi Knives for my son. Found a Japanese Wet Stone Grinder and it cost a bomb--------US$600. Foto show a mall selling nothing but kitchen equipment. Sashimi Knives sells for 300-------300,000 yen.
All bonafide Sashimi Chefs must have one very expensive knife to measure to class.:wall::wall::wall:Bought my son a cheapy version at 7,000 yen.

Your captioned sharpener looks very tempting and I am drooling. No budget for now.Will have to work hard to make some returns on next portfolio of shares.Will K.I.V.

 

[Tin Falcon]

Well Gus as you may have noticed I ordered the Scheppach 10"
about a third of what you are talking
for $600 you had better get a Japanese water stone installed top end motor and bearings and a sliver plated angle gage and yes gold plated contacts on the switch.


the one I orders has a 250 mm alox wheel 250 grit a 200 mm leather hone wheel
1/4 hp continuous duty motor . seems to be a good middle of the road machine and German made.
Guess will have to do tool review when it arrives.
Looking at the pictures again the one I purchased and the grizzly look an awful lot a like. So is this German manufacturing or German engineering ? the good thing is it appears the jigs are pretty standard and the jet, grizzly tormek and Scheppach all use the same jigs. and likely wheels and other parts interchangeable to some extent. HMM

Here is the Hare and Forbes link for the above mentioned grinder.

TiGer-2500-Wet-Stone-Grinder-250-x-50mm/35610/ $319 AUD including tax.
I want not looking for this link but since I found it thought maybe someone down under would appreciate it.

Hi Tin,
Sashimi was a very difficult cuisine to accept and like.As kids we were so ingrained about eating only cooked and raw food is
bad. My first mouth was like torture.Forced to eat raw fish.When dipped into sushi sauce laced with wasabi,it tasted good and different. The Japanese are so fanatically religious on their Sashimi Food Culture. Been watching them fillet and cut fish into smaller edible pieces.A Sashimi serving is so well done with minimal herbs.
Sashimi knifes are also religiously made with very fine grain steel. Sharpening is done by specialists at the Tsujiki Fish Market.The fish vendors have no time to sharpen knifes.Was at same market three years to spy/learn sharpening knifes.

Here is my son's Sashimi Knife. Bought the cheapest--------6000 yen US$60. The edge is razor sharp.Knife seems bit too long(300mm) but right length to cut sashimi at one sliding stroke.

Today is our last day and tomorrow we go home.:wall::wall: There is a very nice looking 100mm Mitu Digital Caliper to look at.And the price is right.

The power of the pen Tin.
I do hope the Scheppach is as good as the Tormek. Look forward to your review.
I dont have any experience with the Scheppach grinder, but do have a Scheppach thicknesser which has given excellent service.
My woodworking equipment from a previous life gets good use again now as I like to incorporate wood into my engine models - handles, bases, framing etc.

 

[Tin Falcon]

well at half the price of the tormek I expect some differences. I expect this to be at least well engineered. many of my power tools are DeWAlt they are imports but well engineered and well made.
The next question is how bad to I need the tool holder set for knives axes etc.
they seem to all be about the same price for a basic set $70. the IPB(Ilusrated parts breakdown)shows plain hat bushing bearings for the shaft but for 100 rpm use that should be fine. and if it gets used an hour a day on average I would be surprised.

Grind bare handed and you will have no trouble with overheated HSS as it will require dipping in water regularly just to hold the stuff.

I have seen the advice that it does not matter if you turn hss blue or even hotter and that you should grind it agressively. When it gets too hot to hold, pliers were recommended. But NOT to dip it in water as this causes microscopic cracking. It should be allowed to air cool (I suppose until you can hold it anyway). I have been bold enough to try this technique occasionally, and it seems to be OK, but I don't really like it.

Hi Lennard,

I visit my daughter in Glenhuntly,Melbourne and sister in Hornsby,Sydney every year.
Please advise names of vendors nearby these cities. Have not seen in Bunnings.If it is not too heavy will buy one and fly home with it. I dabble in carpentry as a young kid watching my uncles in their carpentry shop hand making furnitures.Till today I can't cut straight lines.Now cheating with a Makita bandsaw.

This is the grinder I have, it has gearbox so got the fast dry wheel and the large wet wheel running at much reduced speeds.

 

[gus]

No budget to buy Tormek or the very expensive Japanese eqv,bought these diamond hone files and make do to hone HSS
for fine finishing cuts with Tapmatic Oil.. :hDe:
A DIY wet stone grinder will take up too much space.:wall:

 

[Tinkerer58]

That's easily solved Gus, get a bigger shed so you'll have room for that grinder you're dreaming of.

I originally used a 6" grinder with Norton wheels (don't remember what grit wheel but it was coarse) and it was fine. It did seem to take a bit of time, especially when removing a lot of metal for the trepanning bits.
Coincidentally, my HF 1" belt grinder decided that it had done enough and stopped working. No amount of fiddling would revive it. As I consider most HF stuff to be disposable (IIRC, with coupons, sales, etc. it was about $25) I was going to get another when i started reading about the Kalamazoo 1"x42" belt grinder made in the USA. Their standard motor is a Baldor.
Apparently, most of the knife makers use it exclusively and love it.
Mr. UPS arrived with it yesterday. Based on the knife making guys recommendations, I had ordered some Norton Norox (some ceramic-abrasive blend) belts in 60 and 120 grits and a few Trizact belts in 220 and 400 grit.
Fired it up late last night. I'm sold and finished with the bench grinder for tool bits. The 60 grit Norox removes HSS at an amazing rate. It seems that I can hold the bit longer before io have to cool it.
Took a .25" bit from start to a thin trepanning bit in less than 5 minutes including a belt change to the 220 belt)
Mark me as amazed and a satisfied customer. I was contemplating replacing the HF bench grinder with a 6" Baldor. No need now.

Wait. I forgot to add this. When I was doing wood, I bought a Tormak wet grinder for chisel and plane irons. Its been sitting under its yellow Tormak dust cover since I caught this metal affliction. After reading all of the posts here I'm going to fill the trough and try using it (in fine grade wheel mode)
to give a final honing to the belt-sanded bits. May even go completely around the bend and finish with the leather stopping wheel on the Tormak.
I'll report.

Hi Tinkerer,

I have a better idea. Buy the house next to my sister's in Thornleigh,Sydney.It has a 2 car garage.Now to look for money. Make money from the market.That will be a cool A$600,000 minimum. If I park the car outside then I have a two car size machineshop.Sweet dreams.

Convert the Bosch Bench Grinder to take a worm/wheel gear box to take the water stone. Gear box will be DIY. Another sweet dream.

So many options to look at acquiring a want and not a need.
