Okay,

sharpening

, this is going to be one of the longest chapters in this video, the main reason is that if you can't sharpen, you're going to have a terrible time turning, you're not going to be able to get the wood to cut right, you're going to have to. sand 10 times more and it will be twice as much work. There are several different options for sanding or grinding to keep tools sharp. Some people think you can sharpen them and keep them going forever, right? You can take them to professional

sharpening

services, but the problem is that you go back and use a tool for 10 or 15 minutes, it needs to be sharpened again, so this is something you have to learn to do on your own, it's a little intimidating at first.

If you're not familiar with sharpening but after a little practice, like with a bowl, Turing everything becomes much easier, there are several different ways to do it. I have what I would consider specialized sharpening centers and these are more geared. just for your wood turning tools, they are generally not suitable for your fine tools, like your bench planes or your chisels, but you may get away with sharpening them, like your lawn mower blades, and then they are what I would call multipurpose sharpening systems. and these will sharpen almost anything in your shop again, from lawnmower blades to bench planes and chisels, so let's break them down and look at a number of different things here.

More Interesting Facts About,

sharpening grinders wheels jigs etc by reed gray aka robohippy lengthseconds 1758 ownerp...

You know you're a turner when your table saw is basically a place to store all your other wood turning accessories and I'm definitely no exception in this case, but this is the easiest place for me to display all the different

grinders

from high speed, slow speed, variable speed you want eight seven or six inch

wheels

, it really doesn't make any difference. I think most people find it easier to use the low speed grinder just because they are less intimidating. High-speed

grinders

would be particularly useful if you want to do some serious shaping on your tools. and you want to remove a lot of steel very quickly, if you don't have one like that you might like if you want to take a scraper and round it a lot more than what your profile is, take it to your local saw shop. and most of them will have grinders that they can take it off with and very, very quickly, so this is the first grinder that you get.

It's a no-name eight-inch grinder that goes on sale a couple of times a year. I think it was about 80 dollars when I bought it there about 90 right now it's not a very high quality machine but they work well. One of my woodturning buddies cries every time he sees me bring this to the turning demo because it has gotten so dirty that he is right behind me when I turn and turn a lot of wet wood, so of course this collects a lot of flies of wet wood. I love this type of three-quarter horsepower heavy duty grinder, it's one I can use and abuse.

I'm not going to break it or slow it down and one of the things I like most about it is that when you turn it on it just purrs. This is not just the

wheels

that are there. I never dreamed of having to screw this or clamp it to make it work better because it's not going to move. I just love them. You know if you have the money, they are worth every penny, especially if you are doing production work because they will last forever. Okay, this is a different kind of job. a honing system this is what i would call a wet wheel it is a very slow speed system the channel that contains water keeps the wheel lubricated and fairly clean it runs at very low revs I don't have water in there at the moment it also has a honing station on this side so you can sharpen like your chisels and carving gouges.
It works pretty well for wood turning tools and I think it must work pretty well because there are a ton of clones of this on the market right now. I don't particularly use it very often and it's something I need to experiment with more with those who use it, I just love it, they rant and rave about it and say you get a sharper edge, the edges last longer and I really don't. I know if you want to sharpen a platform this is a little adjustable platform set up and down, this arm moves in and out so you can change the angles and it also has a nice little gouge jig that can sit on there so you can sharpen gouges. pretty much any profile you want, nice little machine.
I actually bought it long before I started turning. I only intended to make my bench chisels and simple irons and I moved away from the world of flat work when I bought my lathe, but it's a good system and it works well this little tool here it's called a workstation sharpening one of the things that I love about your company is one of their mottos is a dull chisel is just a screwdriver which pretty much sums up sharpening and how you use your wooden tools. I would consider this sharpening everything in your workshop, from axes to chisels to bench planes.
They use abrasives and grits from 80 to about 6000 so you can put almost any type of edge on it. what do you want this is a new product for them this is actually a prototype but this is a jig to mount your tormek sharpening guides this is adjustable up and down and in this particular one we are going to show how to make a gouge jig in him so this can change your angles and you can change the angles there so you can get whatever type of profile you want and Jeremiah shows you how to use it.
We are actually very simple to use and runs at a fairly slow speed. so there's no intimidation factor at all, basically if this gets boring just pop in another disc, you don't have to worry about cleaning it or chewing it up like you do with your matrix type wheels and these are also mounted on a glass plate so which is really flat, you get a good consistent surface, well, Jeremiah just showed me this part of this machine, this glass plate, you can put abrasives on both sides, the nifty little things is this, which is an attachment for chisels which apparently is not set up for bias chisels, but has a very useful template for adjusting the ankle.
Can you show how it works? It's a little release lever and it locks, so if you want to sharpen your bench chisels, that's good because the oblique chisels will sharpen it with the tormek

jigs

, so they put braces on. on both sides and again they have a wide range of abrasives that you can put in to be able to sharpen anything on this, okay, this is another variation of what I call the long arm type of gouge

jigs

. I think this was the first one that was made. I once put the long arm this way. I don't use this anymore.
I used to use it a lot because I went to sharpen the deck, but it basically sits on a rotating center. Here you set the slot to the depth you want and I think this was originally set to about two inches for my depth stop. I actually had a little angled bracket like this placed on the board that would give me the depth I wanted. You can change how hard an angle is or what point you have. angle by making it a little bit deeper or a little bit shorter this would go on a swivel center here just take it and turn it if you want it a lot more swept back just turn it a lot more along the edges it works pretty well there are all sorts of homemade versions of these, I just don't use them the more I talk about sharpening our tools, one question that always comes up is what grit stone do you want and of course the answer is that everyone does. a little different on the course site.
I think some people use 60 grit stones for the fine side, some of them go up to 180 320 or some people actually sharpen their cutting edges and I don't know if that makes a huge difference is one of the things I was thinking about was turning the wheel. I was chatting with Mike Mahoney and I mentioned to him that when you sharpen freehand it seems like you're using a pretty rough wheel and he says yeah, I like a more serrated edge because it helps. the wood cut better and I thought hmm. I never thought about that before I started playing with it and most of it probably wouldn't be noticeable to 99.9% of Turners out there, a lot of people have an 80 grit wheel. that works great for scrapers that are a little coarse for my taste. for the gouges this one is 180 grit it works great 120 grit I used them for years the hoenn I don't know if that makes any difference I think the main thing to keep in mind is that you don't want an edge that you have shaved and that works great for your bench, chisels, your bench planes, if you stop and think about it, and with an hour lawyer you can get miles of chips and a A really fine, very delicate edge with which you can shave your face it just doesn't work so it won't hold up to that kind of abuse and the 120 to 80 grit works great these are the original grinding wheels that came with my Baldor grinders work they are not designed for the type of tools that we use, they are rough, one is 36 grit, which is maybe a step or two above the sidewalk, the last one is 60, some people use 60 grit wheels and apparently I have changed their materials because they are a different color .
These are the ones that come with the new one. They will work if you have nothing else, but there is more. They are specifically made to sharpen our sharpening tools and work better. Well, a few years ago I started looking for the best grinding wheel. I bought some add-ons or some in stores that are better than the ones that came with the grinders because most of the ones that come with the grinders are not designed. For the type of grinding and sharpening that we do, I spoke to some of the big names and grinding companies or those that make these types of grinding wheels and they told me that you have two options, one is diamond and the other is CBN.
CBN is cubic boric nitride. I guess I really don't know exactly what it is. It is very common in the medium grinding industry. It is mainly used to make things like molds or blades where they want a profile and it is a very hard material. It does not tarnish and is designed to polish steel. Your diamond works best for carbide or really hard metals. I chose the cbn. Now this is a die type wheel die, meaning it had about 3/8 inch of die. so the abrasive particles, the abrasive particles, are in this mixture, it is placed in an aluminum hub, the aluminum hub has a balanced spin, it will not wobble and will never fall apart, much safer, this particular wheel will wear out a little bit, they cost me Originally, about three hundred dollars was a little expensive, but consider that my wheel is on this side.
I've had this for about six years of production, spinning, still has about half the die left, developing a bit of a run. -They ran out of heavy use and I asked about that and they told me that if you figure your motor shaft has thousands or you have run out of bushing, you may have another thousand or two of wear out and then your hole in the axle in your wheel could have another thousand or two, it had millions of revolutions in the engine and that's going to develop a little bit of runout in your wheels.
You can't fix runout with a diamond grinder, it will eat up the diamond polisher, that's how hard it is to fill and what they gave me to clean the wheels. This is a very, very hard Lumina simulated side grain. This is what they use to shape the wheels and align them when they wear out. I take them out once a year to have them adjusted. It's kind of a pain to do. You know, it's easy for me because I happen to live in the city. Basically, take this and that's all you have to do. do to align the wheels and I have not tried Cindy Drozd as a method of using an oil or a damp bath on these while I am grinding to see if that keeps the wheels clean and one thing I have noticed with these is the 150 grit wheel.
They can make them with any grit you want and the other wheel here, my coarse wheel is 80 grit. When I compare them to the other two steel wheels, their 80 grit is much coarser than this one and the 180 grit which is a disc fine grain for them, it's coarser than this one and I really don't know why they both leave a very nice surface. It tends to look a little more polished than with the aluminum oxide discs but these are very nice because they will always run very very smoothly and it will on any type of grinder you can put it on of course this grinder is brand new and it doesn't have hard dirt, but I need to do extensive testing on this, another excuse to buy more toys just to see which grinding wheels work best.
I will go back and forth between them, but you know they last a long time, you have to pay a lot of money for them, but they are worth it, okay, this grinding wheel is a custom wheel, they have been very common in the metalworking industry, very rare for We in the wood turning industry, as far as I am concerned, this is the wheel of the future, the number one reason it is It has been balanced, so you will never have to worry about it wobbling because it is not balanced. correctly. It is made of one piece of steel, so it will never become eccentric like this.way, you will never develop any runout and the material is here.
It's called CBN, which is cubic boron nitrite or something like that. I'm not sure it's particular, but it's galvanized on this wheel. Security issues. These wheels will never explode. Are there any defective parts? There's no need. I worry about getting hit, my pieces flying and it holding its shape. I have also noticed that it runs much cooler than the standard die wheels and I just like them a lot more, they are more expensive, this was over a hundred and eighty. dollars, but it will last a year and I love them. They come under the heading of specialized grinding wheels.
This is relatively new to the wood turning industry. They have been around in commercial business for a long time, but this is known as a diamond matrix wheel. This is an aluminum cube and this is a matrix, which means a mixture of fine diamond particles that is bonded to the aluminum cube. The good thing about this is that it is already spinning. Balance so you never have problems with imbalance. They are true this way and they are very, very slow. The main advantage is that you will not have to change them. You won't have to move templates.
Because the wheel is wearing out, they last a very long time. I have not worked with the diamond wheels. I use CBN which is another best cleaning material I have ever seen. If you look up Cindy Drozd on YouTube, she does an oil bath with a brush that keeps the wheel clean, they don't seem to develop hardly any wear out, good tool, but I prefer the CBN, okay, this is another type of grinding wheel, this one It's an array, so it's a mix. of aluminum and ceramic particles, this was actually designed and manufactured with wood in Turner's mind for our high speed steel tools.
This is a matrix so it's a mixture of abrasives and some kind of compound to hold it all together if you look at these here. They are small bushings so you can move them for different size shafts depending on the shaft size of your motor, they work great and if you were using a type of die wheel like this this is probably the type that one of those would have. security. Problems for this type of wheel. This is a die wheel, so the abrasive goes into a compound of some kind that they press or heat or whatever to cure it into a nice solid wheel.
One of the warnings that came with my belt or grinder said when you first turn this on, stay away, there are chances it may have cracked or chipped during shipping. You don't want to be in the line of fire if it's a cracked or chipped wheel and if you have cracks or chips then it's time to throw them away. There is another reason to keep all the blade guards in place when using this and many people will usually have a safety shield here at the very least. wear a face mask when you are grinding with one of these this is one of the safety concerns with this type of die wheel that when you change the wheel or put a new wheel on you don't want to overtighten this nut this week Right here what happens It's the same thing that can happen if you tighten it too much when you're wearing your Chuck at 10:00 or at recess, you can break it or bend it or put it under enough tension that any additional tension is going to cause it to break, so I tighten it with my fingers and then I just barely tighten it it doesn't need much to hold it doesn't need much to seat it and keep it in place and stable and firm if I just don't I don't want to tighten it too much, this is a three quarter horse power which is pretty standard.
I consider that a good amount of muscle for these mills. This 3/4 horsepower mill is not as strong as this 3/4 mill here. The biggest difference the horse makes is that if I put a good amount of pressure on the tool when I'm grinding, as trying to remove more steel at once than I normally do will slow it down quite a bit, but not this one. but this one costs a lot more money. I convert wet wood, one of the problems with wet wood and the iron filings you get from sharpening will leave rust stains on the wood.
I like to have this piece of wood here because after you sharpen it, hit it. a few times and that removes most of the iron particles, so hopefully it will remove some of those little black spots that you mysteriously find on your wood a day or two later, so check the list to make sure the wheels are working properly . take off the wheels see how well the axles are working if they are working quite true put the wheels on see how they work you can't because the wheels wobble from side to side it could be because the wheels are not round this way that is A problem: a Sometimes you are mounting washers in there, they may be crooked and if you turn the wheel a quarter or half turn and then tighten them again it will work fine, sometimes it will be one wheel and not the other.
You can never really know and it's actually better to do the leveling with one wheel on, take it off, level the other wheel and then put both wheels on and run them together and see how they work. Another problem that you may encounter with wheels that are not working properly, these are bushings that go inside the wheel and on the motor shaft. Plastic bushings like this are generally not very high quality. For starters, they can get a little drained and can cause some extra vibrations in others. What can be a problem is that sometimes the motor shafts are not straight or perfectly straight and have too much runout, so no matter how true your wheel is, it will never work properly or if your wheels balance is still not going. to be correct because it starts out crooked down there to begin with, if it's that bad sometimes you have to remove them and get another grinder when you first turn these machines on, the wheels can wobble a little. to keep your grinder running smooth and clean, it makes it much easier to keep your tools on the disc when it's moving and there will be several reasons why your discs wobble and I'm going to go over them right now first.
There is something to check and I do this without starting the engine, turning the wheel and seeing if it moves or wobbles, if not that means it is at least half decent if you want to see if it has any eccentricity or wobbles. take a pencil, barely touch it, turn it and you will see that they are marking a little, which means that the wheel is not perfectly round, if it is not round it will wobble, another variation of that is also your side. -Wobbling from side to side again, you can do the same, put a pencil and if you get marks on the side, this one is not so bad, little bumps around that need to be leveled, there is one of the things that can cause your grinder to break. wobble, your wheels wobble and vibrate while you're trying to sharpen and that makes it difficult, this is how we fix it.
You know, I turn this on, it doesn't move that bad, not enough to make this thing move. from the bench, but I like to hold this one or screw it in now to adjust the wheel. This is your average Diamond Dressing Cane, it's not high tech, but it works. If you want to eliminate wobble, you can't just dive in. Put it in the wheel, you have to insert it gently so that it reaches the high points and then gradually work it in a little more, a little more, a little more, until your wheel, since it's round, okay, so I'm on tool support here. move it in, it just starts touching itself.
The main thing it does is hold it steady so it doesn't bounce around. I'll reduce it this way, that won't make it perfectly round, but it makes it a lot better. You can do it. Same on the sides again, use very gentle pressure, move it in until it's barely touching and the other side slows down, so these wheels are generally not very high quality, they will work, you can get upgrades. Pay more money or just go ahead and use this one until it wears out and then get a better wheel later, that's one of the ways to eliminate grinding wheel wobble.
Well, a couple of items on the maintenance of matrix type wheels or your standard aluminum oxide grinding wheels. It is very important to have them perfectly round or as close to them as possible and you need to keep them clean. If metal starts to build up, it won't cut as well, so this is a one-way tool. Again, there are several variations of these on the market, this is one that will align the face of your tooth and clean it up a bit. The nice thing about it is that from the pivot point it keeps it square, so I turn it on and it just does it. the smooth sweep requires very little pressure, so this one is a little off this way, so the view stands out more.
You can screw it back into another tab and continue doing this until the wheels are perfectly clean. If your wheels aren't brown, your brain is going to shake and vibrate all over the place and that just makes it harder to use your tools when you're sharpening. Yes, more toys for the store. This is another type of sharpening station. There are several variations of these. This is like the smallest one. homemade version one instead of your grinding wheels you are using an abrasive strip or sandpaper basically your cloth the advantage with these this will not be unbalanced or true they tend to run a little clearer and cooler than most your drains. wheels, this one is made with an adjustable platform, it comes loose, it has a lock on the back so you can set it to a particular angle that you want if you come down here, this is actually for setting up a couple different types of gouge jigs that They make a nice little system.
If I had one like this in my store, it would work well. The main thing I would like to use on this would be to sharpen the unidirectional tip of your chlorine blades because I think they work a little better flat. This also doesn't leave any concave on the beveled side of your gouges and tools. Some people say it works better. Some people say it makes no difference. I don't really know, I've never used it, but it's a nifty little set and I like that you can preselect and repeat angles through the platform here to sharpen your different tools now I prefer platform sharpening.
This is the adjustable one-way platform here they usually get very close to the wheel and lock it in place a little bit. people will really take and polish this up a little bit so it can come in from the sides. Cautionary note: you don't really want to polish the sides of the wheel, it tends to put lateral pressure and they're not designed for that, but you can adjust the angle to whatever tool you're going to use, lock it in place, just another variation on the platform , Alright. I'm going to have Jeremiah here demonstrate this particular sharpening system, this is not one that a lot of people use.
Use them and there are several similar products, but this is one that he is familiar with so Jeremiah, go ahead, okay, this particular design has a lot of control to adjust the amount of sweep that it will achieve. This is done by adjusting this adjustment bar here up and down depending on what your angle is. If we take this all the way forward, we'll increase the length of the sweep. If we raise it, we'll shorten it, so I have this one. set up for this bowl gouge and I'm going to go ahead and demonstrate how easy it is to use and repeat the sharpening angle which makes it pretty easy, even for beginner Turners, to get that repeatable profile.
This is the depth stop it tells you. how far your tool should stick out beyond the edge of the template here so you can get repeatable language again. Another thing to keep in mind with this particular jig, same with sharpening, you have to control the shape of the profile, but with this. one allows you to use the full width of the wheel, whereas with the single wheel, you're stuck wherever you go where the jig will hold it to the wheel, so some people like the fact that they can really use the whole the width of your grinding material, yes
