Just received mine and put it to the test on a 12" miter blade. After throwing out the written instructions, and only watching your video, I am now a proud owner of a well sharpen miter saw blade. Thank you so much!
Hi Dave, I came across your video while searching blade sharpening. I have a 20 year old 10" SIP table saw which has done me proud, and up until now I had its two blades sharpened at the local 'facility' for less than a fiver for 63 teeth...but they moved away so am having to make a tool to do the job. I have a small lathe and milling machine, but what I didn't have a clue about was whether it's practice to sharpen the faces, or the tops, or both....and yours is the only video I've found that told me this, thank you. I was considering making a seperate deck access panel for the saw with the grinder assembly built onto it for in-situ sharpening.....which would have been simple if face sharpening was all that's needed, but this style looks the way to go, for flexibility, as I also hope to incorporate a jig saw blade sharpening function into it as well. It's also got to do the 4" dia HSS slittling saw blades for the mill too if it works! All the best, Allan
I'm kind of feeling that there's something a little wrong here it terms of the precision of all teeth being exactly the same distance from the center axis. When you "Roll" the tooth off the grinding wheel by hand, do you not allow for there to be a slight difference in that point to axis? I know its an extremely small amount I am talking of. Maybe a 32th of an inch. But just the same, when you have a guide and machine with the possibility of a template plate to slide, is it not possible to make this more precise? Fact that the teeth are on angles, if one tooth is just a touch longer than the rest, That's the one that will wear and make the blade wear unevenly. Also I see you are rolling is the not a chance you have an uneven back slope to each tooth? Just thinking a template slide plate might help. My Dad is cutting very hard words and at times plastics and aluminum where he has taught me the importance of a precise blade. He uses a Milling machine. Just asking. I think you for the post.
Ah James Doyle, I was hoping someone would comment on this. I am thinking that you may have a better grasp of what the problem is here than I but here is what I thought. With the setup as I see it, everything should be locked down except the slide going straight to its stop and straight out again with no rotation of the saw blade. The angle of the diamond wheel should be such that it makes the 15 degree top angle and the desired relief angle on the back slope. By rotating the saw blade the cutting edge is moved around to the part of the diamond wheel that is grinding the relief and removing the entire relief angle.
Wonderfull! I watched your videos and decided to búy such a machine. Its amazingly cheap for the quality, and with your 3 videos Im ready to sharpen many years of dull blades. Thanks.
I really like your teaching style. Easy to follow and well worded narrative. I bought one of these sharpeners a year ago and learned how to use it from you. I like it and just bought two more diamond wheels.
Just bought one too, and the manual that came with it is pretty much useless. These tutorials came in handy and are very thorough and understandable. Thanks for the effort.
Excellent video. All my self sharpened blades seem to drag when cutting. All the previous videos have ignored this step.. Back to the sharpening job. joeB
I have the same sander in my joinery and have been sanding for quite some time, but I have never sanded the top edge of a tooth like you did into an arch. If you don't put the top of the blade on the grinding wheel straight at the right angle, then you will devalue the blade. All you have to do is apply it lightly and the blade will be sharp. I don't like running the blade lengthwise on the grinding wheel at all and would never do it. But maybe it suits you.
Could I not just turn the blade over instead of changing the angle of the motor? Same pitch right, since I flipped the blade by 180 degrees? Just curious have been looking at this machine myself nice to see it in use. Thanks for the hands on info. Jim
great video however you should have a stop set in place to limit the forward movement of the top alternate bevel grind for both directions. this will ensure an even grind on all your tips for symmetry.also do not rotate the blade through the grinding action but rather simply press the tip onto the grinding wheel in a straight in and out action , in until you touch your stop and then back out again. it is best to set your stop to your worst tip and then bring every tooth to the same reference indexing point.
Carl Kellogg Hi Carl and thanks for watching yes i got one off ebay, this is what i typed in as my search 125x10x25x8mm Diamond #150 Grit CNBTR Straight Flat Disc Grinding Wheel Cutter And it came up with many
In order for the face and the back of the tooth to be sharpened in the same way and to be in one plane, as you yourself show, the tooth stop must be set so that when grinding, each tooth can only be ground to a certain depth. If you only grind your teeth by hand, then it will never be sharpened the way you show it should be. I have the same sander in my joinery and I sand quite expensive discs, I would never dare to sand it without a stop. And I've been doing carpentry for 40 years and I'm 68 years old, so I should already have some experience.
I wonder what grit is the grinder blade, what diferant grit wheels can you get and where from. and how do you sharpen other edges of the blade that got blunt as well. You have done nice job, but machine does look less than acurate.
Hello, Since you changed the position of the grinding wheel from the right tooth to the left tooth, are you sure that the diameter of the right tooth and the left tooth is the same?
My chop saw crosscut blade was cutting ok ish but I decided to sharpen to get a better cut. I just sharpened the face, not the tip as well. I didn't put any angle on it. The result was a very difficult cut after I was finished. Any thoughts on what I did wrong
Hi the blade should give you the answer as to what angles to use as for topping the blade I do this if I have any damage or any rounding of the tip which will stop it sharpening
David , as many other say great vid, i was watching your vid , one thing that alarmed me was how much movement there was on sharpening stone. have you noticed it,
Greetings David. Many thanks for sharing your knowledge with us. However I do have a Q for you. When its time for cleaning the diamond disk do you clean with a rubber or do you just use liquid cleaner. Once again top marks for such a good video. OK well I do have another Q where does one buy a new grinding disk. Kind regards.
You seem to be grinding a curved radius on the tip when it should be a straight angled cut so as to get the correct clearance. A curve would cause "rubbing"
I agree. This is because you are "pivoting" the blade which cause a radius cut. Oh indeed. Thus the top grind is NOT flat but slightly curved. Also, there must be a "stop" somewhere; that references each tooth equally with respect to the wheel. Otherwise, one's hand can exert different pressures when grinding. This means that each tooth is NOT ground exactly the same.
@@MrPatdeeee the radiouse is so big in relation to the tip of one tooth that if it create a curve it would be negligible and have no effect on the cut this I know from doing hundreds for blades this way already and using them, but what this action dose do is wear your blade evenly to proelong it's life, as for a stop like with most sharpenings practice removes the need for aids butbthats for the observations it's good to have others views
hi david, awsome video's and information about this. but what kind of blade you have used to on you sharpener? could i use a regular steel blade to sharpen or are there more specific blade to sharpen these? thc in advance
Thank you for your video very educational I enjoyed watching and I purchased one of the machines knowing I would have to do some work to get it running smoothly on the mechanical side The problem I have is when I switch the machine off it trips my power in the workshop every time any ideas thank you Ken
David Gladden I think we’re on the same lines here I brought it home and tried it in doors does exactly the same I re-removed the switch and connected the wires direct and use the plug to switch on and off and it still done it without a switch
@@MRKENNYBOY2 well Ken only thing left is the motor its self. Send it back and get a working one lol, ive never had any issues with mine so i think you was just unlucky to get a dud
It's how I do it and I haven't noticed a problem but now you have mentioned this I will pay attention to it and see if it has any effect on the the blades performance thanks for the comment Ricky
If you look in my playlist for sharpening you will find the full video on this machine this video has a link to the company that sell them, please dont forget to give me a like
Please note, in the video I show piviting the blade on the disc this is Not correct and should not be done, the tooth should go straight in and out of the disc and using the stop to equal the grind on all teeth
Did you know you are a star dave, Yea. Take a look on Alibaba to see who,s video they are using to advertise the sharpener you are doing a how to on.. good price to
Sick Vic the first video ( link at the end) introduces you to the machine there you will find the information needed this video and the following one's cover the use of it and blade sharpening in general, hope this explains enought to help
Thanks for making these videos and nice tutorials I have the Holzmann model which is the same as yours but I Still have a problem and I am looking for help if any one can I will send him a explained email.
@@dmgladden oh of course thank you When I put the blade on the machine then setting the angle ok it is perfect then I finish the operation and looks nice and shiny but from the top side the teeth is razor sharp but the other side is poor I done by my nail The grinding wheel not many uses as what clients say is the blade died after few cuts.
NO disrespect, but you are grinding the tops of the teeth wrongly. The angles of the tooth (in both directions) MUST be ground using a "register" (reference). This is very important. Also, do not move that blade over that wheel. Just move it into the wheel; that the "stop" (on your cast iron ass'y) takes care of. Do not pivot the blade. Let the wheel grind the tooth and then go to the next tooth, etc.. Now that pin ("Paw"l) is extremely important in making sure that EVERY tooth has the exact same angle, both left and right. This can NOT be done unless you reference the tooth using the pawl. If you do not, you ruin the reason for the two angles; that manufacturer have "honed" over many decades. I can not stress this enough. Again, NO disrespect atoll.
Thank you for the pointer, after a bit more research I can fully agree with you, it would be the correct process to not pivot the blade I did discover this sometime after making this video which overpowered the previous teachings I got on preserving the grinding disc which in it's own right has a good point but the purpose is after all topping a blade not preserving a grinding disc.
I just one of these sharpeners and i got stuck trying to figure out the indexing pawl /pin and how to set it up . Sadly this is the third video Ive watched and haven't learned this process. the pawl / pin together with the stop ensure the tooth is offered to the disk same each time. Grinding the front of the tooth is a bit odd.
