Mini Grinder for Ultimate Scrapers

About This Item

Fast, simple sharpening for our Ultimate Scrapers
The grinding wheel is the correct diameter for maintaining the hollow-ground edge of the Ultimate Scrapers. The second wheel is an abrasive fiber that's useful for cleaning and deburring metal parts.

We added a custom steel table to our Mini Grinder, created solely to support the Ultimate Scrapers while sharpening. These beefy scrapers are thicker than standard scrapers, and with two cutting edges they present some challenges when it comes to sharpening. If you use our Ultimate Scrapers, then our Mini Grinder is the tool you need for a quick and accurate edge.

Less time sharpening = more time building
An incorrectly sharpened scraper tends to leave scratches and a rough feel, but a properly tuned one will leave a glass smooth surface with no extra sanding required. The tempered steel Ultimate Scraper holds its edge longer than most scrapers, even when working with hard woods.

Sharpening our Ultimate Scrapers has never been so simple: Place the scraper face down on the large table and move the edge slowly and easily across the wheel—in a matter of seconds it will be sharp and ready to get back to work. Grinder setup and sharpening instructions included.

Overall dimensions: 6" x 10" (152mm x 254mm)
Custom steel table: 2-1/4" x 4" (57mm x 101mm)
Grinding/sharpening wheel: 3" diameter (76mm)
Fiber/polishing wheel: 3" diameter (76mm)
Eye shield for each wheel

Perfect for scraper

After buying the scraper I really needed this grinder and does a great job.

Good, but Pricey

By

Verified Buyer


This little grinder is set up just for sharpening the heavy Ultimate Scraper. I found one that looked similar at my local home store and originally bought that one for about $40 (it might have been on sale). I used it for a while and it worked, but it was a little anemic, bogging down easily. I decided to get one directly from StewMac, thinking it might be a little more powerful. Apart from the special guide, it was pretty much the same machine. It works well, but is not very powerful. I'm not sure how useful it will be for other tasks.

I love the scrapers, but am more ambivalent about this grinder. I suspect someone will find a better solution. Until then, this machine works well enough. I wonder if a finer wheel on the left spindle would be helpful.

Not o/s for its torque but nice little grinder. Be great if it shipped with flexible shaft attachment!

Not a review but a suggestion

I have a similar grinder that I purchased elsewhere (before stewmac offered this one). I changed out one wheel for a cotton buffing wheel and use it for nuts and saddles. It's perfect for this task as you can regulate speed for plastic (slow), tusq (medium) or bone (medium high) speed. Also used it to polish machined acrylic parts after wet sanding to make them transparent again. Grinder works great on small parts too!

Love this little guy!

It is very small - the motor is smaller than a Coke can but there is a lot of power. I read some reviews that said the unit they received wasn't powerful enough. I guess that was the luck of the draw, but StewMac will exchange it. So if you get a weak one just have them replace it. Anyway, I love the small size - if you are like me, you already have too many things in your work room, but you can store this away in a corner, drawer, or the back of the bench. Don't expect to sharpen your lawn mower blade with it, but for scrapers, it's the deal.

Great Idea: Disappointing Results

By

Verified Buyer


I purchased this tool because I have three Ultimate Scrappers that I use daily building violins, Dobros, Mandolins and Guitars. I tried it out today and was disappointed in the rough surface the Stew-Mac grinder left on my scrappers. I usually sharpen these scrappers with excellent results on my Tormek T-7. However I wanted to have a dedicated grinder to avoid the set up time. The Stew-Mac grinder leaves a rough surface on the tools that produce dust when scrapping. The Tormek leaves a mirror finish and a sharp properly functioning scraper. I will return this item, but would welcome a professional quality soulution for a dedicated grinder.

Tiny but good

This cute little grinder has a composite and a fine wheel, both 3". It has already seen a bunch of use in the first week, for small jobs that it was perfect for. You do have to keep the speed turned up and use a light to moderate touch or it will bog. Plan appropriately and use it for the jobs it is sized for and you will be very happy.

Has a specific use making it worth having if you have extra $

By

Verified Buyer


This little beast is totally underpowered, but has 1 use that makes it worth having. It just went on sale for $25.00 less than I paid last month, but I'm still happy to have it. It's saving grace is that the wheel is just the right size for sharpening Ultimate Scrapers. I've used those scrapers for years and have learned to sharpen them somewhat by hand with a diamond stone, but this little grinder does a much better job. And, it is a nice red color too!

It Does the Job

I almost didn’t buy this 3” bench grinder because of the last three poor reviews… I drove to that Cheep Chinese Tool Store (you know the one) and looked at their version… I couldn’t say that this grinder is better or worse than the ½ price version that you find elsewhere… What you are getting here for the extra $40+ is the larger custom platform to place the scraper on while sharpening… and I will say that the larger surface is needed to smoothly slide the large curved scraper around during sharpening.

And yes… if you have a piece of scrap 3” aluminum angle and an hour or two to fiddle around with it, you could make a larger platform to go on the cheaper version that would likely work just as well. But this unit worked for me in about 15 min from opening the box which is what I wanted.

Concerning the complaints that it bogs down and doesn’t have power to take on “normal tasks”… It took me less than 1 min to sharpen my scraper once I got it set up. I would guess that if you are bogging it down while sharpening your scraper, you may be putting too much pressure on it. A couple light passes on each side and I had a nice sharp edge.

Just know that this little grinder “is what it is”… an inexpensive solution for sharpening your scraper... It probably will not become your go-to bench grinder that you hand down from generation to generation and use for a large array of shop tasks. It works well for the task of sharpening the scraper…. And for that use, I recommend it.
