I have finally had enough of fighting with my MKII power sharpener, and am moving on. One of the only veritas tools I own that I am truly disappointed in. So...I need a replacement power sharpening system, and am trying one of the Viel grinders. I have a motor, its rigged so the belt grinds down (direction) and have figured out a simple way to set bevels. I have a couple quick questions for anyone.

What grits of belt would you use? I have a trizac belt I really like, so I would likely stay with thos ones. They come in 240x, 400x, 800x, 1400x, and 2000x (nominally.)
Would you bother with a micro bevel? It would be simpler to set the rest to 25 degrees and carry on. Micro bevels would be simple, I would just prop the blade up a little with a shim like a popsicle stick. But still, are they really necessary if I'm not worried about the time savings they offer? I am thinking they aren't.
Would there be any benefit to a strop? I have the stropping belt for knives, would there be anything to be gained on edge tools?
Is there a simple way to reverse an AC motor? Would make stropping with the tool rest much easier.

I am committed to power sharpening. My hands are too screwed to hand sharpen (even though I get a real sense of joy from hand sharpening, and am reasonably good at it) and then do any woodworking on the same day. Sucks, but there it is. I can do quick touch ups on a strop or my 8000 gold stone, but that's about it. Oh, and I don't trust my hands enough any more to use a grinder.

Any suggestions are deeply appreciated!

I have an old bench grinder that I fabbed up one side of as a belt grinder to use 1" x 30" belts. it's a bit of a kludge, but it works fine. I think if I were in your shoes I'd set up a bench grinder with 2 belts, one pretty coarse for the primary bevel, one quite fine for a microbevel, with rests to match.

If I were in your situation, I would do a 23 degree or 25 degree primary bevel and then use the 2000x trizact afterward with a microbevel a couple of degrees higher. Any more work than that won't get your a sharper or stronger edge, and will be inviting heat problems - especially with a trizact belt against a platen. You'll quickly find out just how much heat they can make quickly - in a second if you pause, you'll see the edge turn orange if you have a fine belt and any pressure against the platen.

It's my opinion that you want the edge feeding into the tool, and you can finish and hold the tool edge down then to strop. I have a viel grinder that was made by some carving outfit (or put together by one) and I attempted to switch the wiring so that I could get the belt to go the other way, and I toasted the motor and eventually just got a kalamazoo grinder (which has a much better belt speed and miles better motor, but the rest is not made for sharpening woodworking tools.

For grinding, you'd be fine with the cheapest aluminum oxide belts you could find. You could do a lot of in between touchups with a 2000 grit trizact belt before you had to grind again.

I personally think switching the belts on the grinders is a pain, and would rather have one doing the grinding and something else doing the honing part just to avoid switching the belts.

Given your issue with using your hands to sharpen I really am not sure about power sharpening to achieve a suitable edge for woodworking. My only recommendation would be to go with a Tormek but the system you have now may be workable, I just haven't got the experience to tell you otherwise.

But as far as your motor goes, it depends on what type it is. Single phase AC motors can sometimes be tricky to reverse but should be doable. You will need to open up the end of the motor and find your coils. There should be a starting coil on your motor and these are the two leads you will need to swap in order to reverse it. Some pictures would be really helpful for me to explain better. Maybe if you google how someone may have a tutorial on the process.

Tony, I can do fine work with my hands, its just the act of scrubbing on a stone hurts them terribly. So accuracy on an edge is ok. In fact, I just did an experiment where I ground a paring chisel (already reasonably sharp) on the viel, and got a very serviceable edge in quick order. The motor runs fine, and I think I'll leave it be. I can strop by hand, if need be (rather not!) or maybe pinch the blade against the belt right at the platen.

David, I agree with you about switching the belts, but I don't mind just doing it once per sharpening cycle. Do you think I could get away with a "grinding" grit, say, 400 or so, and a honing/polishing grit, and call it a day? The polishing grit would remain on almost all the time I would think. Do you think I need to strop?

Paul, I'm not thrilled with the Veritas Mk II power sharpener either for a variety of picky reasons, but I can make it work. Just wondering what the problem is? Getting the PSA adhesive off the aluminum platter without ruining them? The support bar isn't level? More steel removed along the outside out the platter than the inside? At least those are some of my gripes.

That said, I have never blued an edge on the Mk II. Can't say the same for the Viel 1 x 42. I agree with David about the Trizact belts. Prefer the others. I know lots of people get great results with that grinder, but I don't. I do think it is the best thing I have ever used for knives and axe heads because you're using it above the platen. But I have heat problems using it with the metal platen.

I don't have a Tormek, but based on the grinding thread, I am about to follow Derek's lead and get a CBN wheel for my slow speed grinder. I am debating between the Tormek Grinder attachment with the Tormek Jigs (around $300) and the Robo Rest from Reed Gray (Robo Hippy). Just found out about Reed's jig today and it looks promising. I have the Lee Valley grinding stand, but would prefer something where it's a little easier to get repeatable angles. I'll finish on stones, but it doesn't seem like that should be a lot of work with a hollow grind.

Just some thoughts.

Paul,

I am also curious as to the problems you are having with the MK II.

My problem at first was avoiding unwanted secondary bevels. I used the discarded backings to adjust the platen height to take care of that.

Out of square edges were easy to eliminate by using both sides of the disk surface. In other words sometimes they disk would be pushing grit into the edge and sometimes the grit would be pulling from the edge.

I sometimes freehand my lathe tools on the MK II.

I am convinced there isn't a perfect system for everyone. For my purposes the MK II covers a lot of my needs. Mine gets used to sharpen axes, shovels and even the points on an awl besides the chisel and plane blade work it gets.

I use the Viel with a 40 grit belt for coarse removal, I was able to remove 3/16" off a plane blade and change the bevel angle with that combination and the blade only got warm. I've tried to use the the Viel on a lark to see if It could handle an entire sharpening job. It works great for cambered plane blades/knives/axes. I go from 400, to 1k Trizact, to a leather belt with CrOx ( I wired my sander with a reverse for strop duty). My edge could pop hair so easily. I just don't feel the narrow platen and belts can maintain the geometric accuracy for straight edged tools like chisels, so I use my viel and the coarsest belt I can find for reshaping duties, then I go to a bench grinder for a hollow grind and follow up with stones. For tools with camber or curvature though, it is definitely nice.

Yeah, I can't figure out what I'm doing wrong. I can't get a repeatable edge without huge amounts of grief. My first bevel setter was strangely bent, so it wouldn't give anywhere near consistent results. Of course, Lee Valley replaced it happily. A little better, but it is still impossibly finicky for me. I even have trouble getting the damn thing tight enough that it won't wander around on the platter, which screws up my bevels. Having to run out all the way, leaving some of the tool hanging off makes it easier to burn the tools.
I have fought with it for 2.5 years, and kinda had enough. I really, really, really want to like it. But I just can't.

Christian, I have the Veritas grinding jig, and the holder does fit the slot on the viel. So keeping edges straight is pretty straightforward. I'm also not as anal about that as I up suspect I should be, so freehand works fine as well.

Im curious, did you rewire a whole sander for stropping, or put a switch on the same one you use in forward?

Christian Castillo
11-04-2014, 7:43 PM
I was free handing everything, I havent tried using the set up with the grinding jig, but that sounds like it'll handle the only problem I had with it. I wired it up to a double throw switch that I can flick up to have the belt rotate upward, or flick down to have the belt rotate down. I have been meaning to buy a foot pedal as well to make touching up with a strop really easy, or just make it much more convenient for knife sharpening.

Would you mind sharing how you wired that? I would love to be able to reverse the motor, but am stymied.

Many AC motors have a reversing jumper or changing of wiring will reverse the motor.

Remember you might get smoke and sparks if you try reversing an electric motor with the power on.

Paul,

It may be you are trying to make this more exact than it needs to be. A piece of wood will not know whether the bevel is 25º or 27º.

I would appreciate a different design on the knurled nuts. Wing nuts might be better. Do you tighten the nuts on both sides of the holder?

I seldom have any of the tool hanging off the edge. This is something I only do when working the edge of a shovel or maybe an axe.

No matter, if the blade feels hot, it is rocked back off of the abrasive and allowed to cool or is dipped in water. When possible it works to be working on a few blades at the same time. I have 5 holders to allow for this. That seems to be enough to allow for air cooling when working on blades. My set up doesn't get as much use as in the past. When I was buying a lot of blades and planes there was a lot of work. Now it is an occasional touch up or reestablishing a bevel. Most of my sharpening is free hand. Even on the MK II I will forgo a holder, use the rest as a guide and eyeball the angle. A couple slaps on an Arkansas stone and it is back to the lathe.

Typically I lightly tighten the nuts while the blade and holder are resting on the setup gauge. Then the blade is checked to make sure it is touching the side of the holder at both the front and the back. Then the nuts are tightened. I can usually work a pretty strong grip but if need be I would use some pliers. Maybe have a pair with tape on the jaws since there are enough things that need tightening but I wouldn't want the jaws to gouge anything.

The geometry of the thing is a touch odd. Because of the thickness of the abrasives the angle changes between the plates if you are using 4 steps of abrasive. If one wants a micro bevel, this could be an advantage. If one doesn't want a micro bevel, it takes a little bit of shimming to make it even.

Another thing that bugs me is the plate holding screw has a right hand thread and often comes loose. I found a faucet 'o'-ring that fits the bottom of the nut and offers a little compression to hold the nut better.

If you ever wonder down toward Portland, OR give me a heads up and maybe we can get together and figure out how you might get better results.

I just can't get the damn thing to sharpen with anywhere near repeatable results. I also can't get the bevel to be consistent. And I can't get it consistently sharp. Even after 2 1/2 years.
I have no problem getting the medium down without wrinkles or bubbles. The blade does have to hang off in order to get a reasonably even grind on plane blades. Maybe I'm just too dumb to use such a fine tool. :-)
Just to be clear, I don't really care about the angle, as long as its consistent. And I'm not 100% convinced I care about using a microbevel, (isn't that really to save time sharpening, more than anything? I know Leonard Lee wasn't too keen on them, for example) as long as I get sharp.
Like I said, $400 for a lot of aggravation. Still love Lee Valley and Veritas. Just not this particular tool.

Paul,

I know 2-1/2 years with the Mk II is probably exhausting, but I will make one suggestion that helped me. I still don't use it, but can get a sharp and repeatable edge.

I had three problems with Mk II.

1. The projection setting jig only works if the blade is perfectly square. So, use a square and grind the edge to make sure it's square before even starting.

2. When I place the blade holding jig onto the projection setting jig, I always press the edge of the blade firmly into the corner of the protrusion setting jig. But, as soon as I start tightening the blade holding jig, I find that the edge of the blade started rising out of the corner, so that the blade projection is changing. So, what I need to do is tighten the blade holding jig slowly, while simultaneously pressing the edge of the blade into the corner, so that the edge of the blade is still in the corner when the blade holding jig is fully tightened.

3. Last part is to get your square and check to see if the blade is really square in the blade holding jig. I found that it often wasn't and I needed to give it a few taps to make sure it was square. If you do that, you need to go back to the projection setting jig to make sure the edge of the blade is still in the corner. Otherwise, loosen and adjust.

That process id one of the reasons I stopped using the Mk II. But, if the edge if square to the blade holding jig and the edge touches the inside corner of the projection setting jig, the system should work.

I assume you've already done this, but you should also check to see that the horizontal tool rest is parallel to platter. The booklet has instructions on how to do that. It's pretty easy.

Finally, you do need to let the abrasive do the work, so don't press too hard. The instruction say no to let the blade go past the edge of the platter, but I find that to it's impossible to get an even bevel without doing that. So, I move the blade to the left and right, going part the edge, just being careful to make sure the blade holding jig stays firmly in contact with the horizontal arm. Eventually, you get the feel for how to move the blade across the platter to get a straight bevel. Once you've done that with the 80 grit, the rest of it seems to move pretty quickly.

Hope some of that helps. If not, I tried.

One more thing, which you may already know. The crepe blocks work fine to clean the more abrasive stuff, but they don't work with the finer grits and really gum up the 9 micron sheet. Use a white eraser for the finer grit sheets. Works like a charm.

Steve

Steve, I have tried almost all the things you mention. I even dedicated a small square to my sharpening area full time, cause the thing is so picky. I haven't tried the white eraser, what a great idea. I agree the tool can't be used without leaving the platter.
i think all the rigmarole with getting the blade square is part of my frustration. That plus the fact that my original setting jig was bent just enough to create a lot of grief.
i think part of my frustration lies in the fact that I get way better edges with the Viel, with way less grief, far more quickly. So I assume I am doing something wrong. Cause I think that shouldn't be true.

Not sure I should speak up here but on the off chance that I can spark something good, I shall. I have a Delta 1 x 42" belt grinder, a Worksharp 3000, a Delta 23-700 wet grinder and a generic HF grade 6" grinder. My hands are afflicted with essential tremors - makes even typing difficult and freehanding anything about impossible. I have come to the view that power is great for re/establishing a bevel. I flat grind so once a bevel is established I mostly don't need power again - at least for a long time. I use the belt grinder for knives, axes and such. With a leather strop belt, one can put a wonderful edge on knives in a matter of seconds. I haven't figured out how to jig it for chisels and such. The Worksharp does a fine job of creating bevels so I use that.

I use Stu's famous 3 stone Sigma kit for final honing with either a Veritas MK II or Kell honing jig. Takes a minute to get jigged up, especially with my shaky hands, but only another minute or two to go through the 3 stones for a wonderful edge. If your hands can handle using a honing jig I would like to respectfully suggest a similar approach.

You are on your own when it comes to turning tools - I don't have any. :D

I have a Veritas MKII power sharpener and along with some diamond lapping films I use on glass for the backs, this is the entire set up I have for chisels and plane blades. Honestly, I never had any issues getting sharp edges with this setup. Reading all the complaints makes me think whether there is something wrong with your setup or perhaps there is desire for more perfection than functionally needed. I can't question the latter, but not sure of the first.

Hope you feel you got all the help you needed from the good folks at Lee Valley to make sure there is nothing wrong with your setup.

Doh! I meant to say this since Paul is in Victoria, BC.

There is an LV store in Victoria. Maybe give them a call and see if someone in the store is able to help you with the set up.

That would be quicker than a trip to Portland.

Another thought came to mind. I do not remove a blade from the holder until that blade is finished through all the grits. This was one of my reason to buy extra holders.

Ok, I just tried all the suggestions you made, Steve. I tried the first one, and I'm now pretty sure my edges are and were square. Your procedure pretty well matches mine.
Your second suggestion is also very close to my regular procedure. I followed very carefully, and got a square edge, which is pretty much how it always came out. Of course, the second blade I tried slipped, and ground unsquare. Argh.
I do use a square with my jig. In fact, I have a small engineers square stored next to my MKII for this very purpose. I'm still getting really unrepeatable results. Of course, in one of my retries, I peeled the abrasive off. Another problem that thankfully doesn't happen too much.
For crying out loud.

I have finally had enough of fighting with my MKII power sharpener, and am moving on. One of the only veritas tools I own that I am truly disappointed in. So...I need a replacement power sharpening system, and am trying one of the Viel grinders. I have a motor, its rigged so the belt grinds down (direction) and have figured out a simple way to set bevels. I have a couple quick questions for anyone.

What grits of belt would you use? I have a trizac belt I really like, so I would likely stay with thos ones. They come in 240x, 400x, 800x, 1400x, and 2000x (nominally.)
Would you bother with a micro bevel? It would be simpler to set the rest to 25 degrees and carry on. Micro bevels would be simple, I would just prop the blade up a little with a shim like a popsicle stick. But still, are they really necessary if I'm not worried about the time savings they offer? I am thinking they aren't.
Would there be any benefit to a strop? I have the stropping belt for knives, would there be anything to be gained on edge tools?
Is there a simple way to reverse an AC motor? Would make stropping with the tool rest much easier.

I am committed to power sharpening. My hands are too screwed to hand sharpen (even though I get a real sense of joy from hand sharpening, and am reasonably good at it) and then do any woodworking on the same day. Sucks, but there it is. I can do quick touch ups on a strop or my 8000 gold stone, but that's about it. Oh, and I don't trust my hands enough any more to use a grinder.

Any suggestions are deeply appreciated!

I've been angry with this sharpener since I bought it. However, it is very accurate when it finally does get tight. The bonus is the 3 degree micro bevel wheel that works very well. I found a clear hose that jam fit over the adjusting knobs and cut them to length. Now I use vise grips to tighten it after I get it square with a small steel engineers square. I just did that today and will try to find a better device to tighten it.
I considered sending messages to Veritas because I think they may listen a little better than most, but this problem has been out there so long they have to know about it. The real problem is the threads are too coarse to tighten with just your fingers, as you know so very well. This is compounded by the nut being made of brass which may not take the pressure put on them with fine threads. If that is the case then they will probably strip out on mine with me using vise grips on them. If they do, I'll make some from steel with a through hole to put a nail through for tightening like I do my old Stanley #80 Scraper. Wing nuts would be ideal but I doubt I'll be able to find any the right thread size. I intend to look, but I haven't even ascertained the thread type yet.

Use a hacksaw to saw a slot in the knob. you can then use a screwdriver to tighten.

Does this work for you? I'm not sure I could get them tight enough with a screwdriver. I have to crank pretty hard with the vise grips.

Have you tried using a lock washer?

Are some people perhaps confusing the Veritas Mk.II Power Sharpening System with the Veritas Mk.II Honing Guide?

Two different animals and I think Lee Valley messed up by naming them as such. Similar to what Microsoft did with Office 365.

My Tormek taught me how to recognize repeatable results: it works consistently. My Sigma stones (along with a few Chosera's and Besters) showed me how much sharper I could get than with Tormek. With that said, my Tormek will achieve about a 4-5000 edge with polishing, and that's plenty good to work most wood. To work end grain, I use stones to achieve 10k+ edges. Such edges leave end grain with a satin shine of smoothness.

I've tried a bunch of methods (and have several grinders with various wheels). Of the grinders, Tormek is the slowest!!! Yet, no other stone grinder can achieve the edge sharpness without temper issues or with the same excellent sharpness of the Tormek. However, one friend with a quite pricey knife belt grinder can surpass my Tormek in every category (including price).

So, IMO, Tormek is king of the stone grinders but doesn't keep that honor compared to the results that can be achieved by ceramic stones or better quality knife belt grinders. OTOH, my buddy's knife grinder will tear up a digit in seconds while the Tormek is very safe. Each method works, has pro's and con's, and can achieve "acceptable" degrees of sharpness.

How would that help? The problem is the force required.
