    I used this technique on my first table saw (a half junk saw with thin sheet metal base) and it really did work well. Made a big difference.

    I used your method on my saw too - really made a big difference.
    Impressive that you still have the original blade. I would have cut that up into throwing knives or washers by now :D

    Most manufacturers set the quality dial at 'just good enuf'. Things usually will not improve unless customers voice the issues. So I encourage folks to give their feedback to the manufacturer - both good and bad - so that things can improve (if the manufacturer hears enough feedback, and cares enough.) Do your part, and let them know.
    Thanks for sharing Matthias.

    I used to work as an engineer at a marble factory where we deal with blades over 1 meter in diameter.
    The flange face that makes contact with the blade has an inner and outer diameter. The flange face actually should not be flat, i.e., less than 90 degrees from the axle. There should be a slight angle inward so initially, what should be touching the blade is just the outer diameter of the flange.
    As you tighten the nut, the force pushes the flange from the center. This actually "flattens out" the whole face. So if you grind it flat, the outer part will flare out as you tighten it and only the inner part of the flange will grip the blade, hence the wobble.

      That fricken flange was a rickety rocking chair. So Delta machined neither the flange nor the arbor. How are we supposed to machine a slight angle without a metal lathe. Delta POS sucks!!

    • @HamidA-to8vy
      @HamidA-to8vy 9 ปีที่แล้ว

      +boksbox Before anything, what is the acceptable tolerance? what is the reference or specifications that machine should comply to. For one digit of variations which could be due to to the motion rather than the flatness cannot be perfect more than that for this kind of dial. Then considering even within the bearing itself there is few microns of clearance. High precision bearings such as air and magnetic bearing are out of the price and application range of this machine. All in all, it looks well made machine. May be the blade need to be upgraded

    • @boksbox
      @boksbox 9 ปีที่แล้ว +2

      +Hamid A It is specified by the blade manufacturer. Typically around 0.25mm side runout for 275-350mm diameter blades.

  • @thejoshmoss
    @thejoshmoss 9 ปีที่แล้ว +2

    That is a fantastically tiny wobble, I only wish I had any tool that was so true that a .01mm wobble would be worth fixing. I'm glad you pushed on the arbor to show just how tiny the movement is.

    Thank you for the very helpful video. ( and many of your others which i have shamelessly copied from). I really appreciate the time you take to share your knowledge. Perhaps I can add a little to the conversation. I have an old old saw that has been beaten up by many previous owners. I too had really bad table saw wobble. Bought a new blade, now just had bad wobble (2-3 mm at blade tip). I found your video with great relief. I measured the arbour play and it was about 2-5 thou out. I was then all set to grind the arbour flange. But then I checked the saw flanges. I had two aluminium ones that fitted either side of the blade. Upon closer inspection they were knackered with over tightening and general abuse. So I hunted around the shed found an old substantial flange used for a grinding wheel that was flat. I ditched both aluminium flanges, had a quick file of the fitted flange, fitted the saw blade directly against the fixed arbour flange, put the newly found grinding flange on the other side, tightened the nut and my 3mm play at the saw tip was reduced to 6 thou. not perfect but i have just finished ripping 50 metres of hardwood with very smooth results.
    So my suggested contribution is before grinding away at the arbour flange, check your removable flanges and make sure they are not the contributor to your wobble.
    thank you again for guiding me to a good solution

    You got some nice results here! I have a 1974 Delta/Rockwell Unisaw that I rebuilt about 5 years ago. I checked run-out at that time and did have about 5 thousands. I used a similar method, but with a power grinder to true mine up. Well worth the time.

    Good technique,the machine shop term is "grinding insitu" which is used to achieve absolute runout on a variety of machine tool spindles.
    That last few ten-thousandths you are seeing is probably the accuracy limits of the bearings used in the saw's arbor.What you have done is probably as good as it will ever be,well done!

    I recently rebuilt my Delta contractors saw with new arbor bearings, arbor and arbor bracket. Noticed the arbor was NOT true. Put it in a metal lathe and turned the arbor face. Dialed in the tracking to the miter slot and made an incredible difference. LOVE IT. Had the saw since new in 1992.

    @stevenhardy2898 9 ปีที่แล้ว +1

    I agree with what you done so far Mathias. I would like to add to it a little. As you showed on the video, which is excellent ,just touching the arbor or tabletop would show a deflection. With this in mind, its easy to then understand that vibrations in the belt (s) can result in deflections in the blade, especially during the first 5-10 minutes of operation of the table saw. In the mid 90's I turned a sears table saw into a super smooth cutter by a couple simple ,not too pricey corrections . The first was by replacement of the original belt with a Browning FHP automotive belt (cogged) and by the addition of blade stabilizers to stiffen the thin kerf blades. Believe it or not ,the inexpensive Piranha blades could be made to cut extremely smooth on 3/4 inch red oak ,with or against the grain.( When I updated to a Rockwell Unisaw with new bearings and a Freud blade I did not get a smoother cut but just the ability to maintain that smoothness up to 3inch oak due to the additional HP) To test if you might gain from a quality belt is easy. Make a test cut ,then leave your tablesaw to run about 20 minutes doing nothing. Then do another cut. If there is noticeable improvement,there may be an issue with your belt/pulleys.....especially if any of them are crappy cast aluminum.

  • @GreenAppelPie
    @GreenAppelPie 9 ปีที่แล้ว +3

    It really grinds my gears that saws don't come with good alignment or a perfectly flat arbor, or even a decent blade. I worked with a saw that made rather poor cuts but got tired of it and finally researched it, I bought a depth gauge and honing stone. I found the Z alignment out by about 2 degrees (yes from the factory) and had about the exact same experience as you did with the arbor.
    I wholeheartedly recommend Frueds Diablo blades in the as-many-teeth-as-you-can-get variety, these blades are amazing. With all this, my saw cuts like it should, just like yours. You really feels no resistance when cutting soft woods and a great finish. If I built saws, they would leave my factory like this, there no pride in factory craftsmanship these days.

    Really made a huge difference!

    Used this method today on my 12" SIP saw here in Ireland.
    Picked the saw up a few days ago and noticed the wobble of 0.5mm over 12". Assumed it was the blade so I fitted a new Freud 10" blade I had in the garage (luckily both 10" and 12" saws here in Europe have 30mm shafts) the 10" had pretty much the same wobble. Put a dial on the arbour and found it was out by around 0.2mm (I have a metric dial)
    Found that the two holes drilled into the arbour flange had distorted the mounting face where the blade sits.
    Terrible design...
    Raised the arbour and set to 45 degrees and held my diamond plate against it for a few seconds with the 400grit side, it clattered a bit then stopped after a shart while. I wiped the face clean and then held the 1000grit diamaond against it for a few seconds. I now have at most 0.005mm on the arbour face. Whole process took around 5mins.
    The diamond sharpening stone/ plate also works great on the cast iron table and tracks.

    • @beanMosheen
      @beanMosheen 9 ปีที่แล้ว +1

      How to figure out if it's a bent blade or arbor: measure the high spot, mark the arbor and blade with a sharpie. Loosen the nut and clock the blade 90deg and retighten. Did the wobble follow the blade or the arbor?

    Mattias did you ever think that maybe putting in some good quality bearings might make a difference? The 36-650 and 655 were actually made with cheap bearings. Also straightening the teeth of a tablesaw blade to less than 0.001 works wonders.

    @ToolTalkCanada 6 ปีที่แล้ว +1

    Great video! I may try something this on my old Beaver table saw. Maybe I'm missing something, but wouldn't it be better to set the blade to zero degrees, clamp the stone to the table saw fence, position the fence so the stone will just kiss the arbor, and then raise the spinning arbor to touch the stone? Seems better than finding heavy steel bars and moving the stone by hand. Any thoughts?

    This might be irrelevant, but did you try cleaning the arbor after grinding it? By rubbing a wet paper towel against the arbor while spinning, you'll remove a surprising amount of leftover particles.

  • @esotericsean
    @esotericsean 9 ปีที่แล้ว +1

    Matthias, can you talk about why certain types of blades work better for different types of wood. I know you mentioned your Freud blade with square cutting heads once, but I'm curious about the differences with blades designed to cut plywood versus solid wood. I don't know when I should be switching my blade.

    • @Goggalor624
      @Goggalor624 9 ปีที่แล้ว +4

      +esotericsean
      Not Matthias but since it's been a week, I thought I'd help you or anyone else interested out a little. Typically with blades, the less teeth there are and the bigger the gullets between them, the better they are for ripping(cutting with the grain). They cut faster, too.
      A blade with a lot of teeth(like 60+) is used for crosscutting(cutting across the grain). The more teeth there are, the less tear-out you'll typically get. These types of blades are usually good with veneered plywood, too, since they excel with tear-out. The down side is they cut slower and can burn(there's also more teeth to sharpen when that time comes around).
      Most people hate switching back and forth between a crosscutting blade and rip blade so they buy a combination blade. These blades are designed to combine aspects from both types of blades to get the best of both worlds from the same blade. They're not perfect but they're a nice compromise. I personally use a Freud Fusion blade and find it to be excellent with both crosscutting and ripping.
      Beyond the type of blade, there's also the type of tooth grind on the blades. There's Flat grinds, Alternating Top Bevel, High ATB, Triple Chip Grind, etc. You can research those more if you like but just for a quick rundown you want a flat grind if you plan on doing things that need a flat bottom saw kerf like dadoes, splines, etc. TCG is used for harder materials like melamine, I think(never used them). ATB and High ATB are good for crosscutting since the high angles of the teeth score the wood fibers before they're scraped away by another tooth which results in less tear-out.
      There's more to learn but that should give you a decent start. Most combination table saw blades use an ATB or High-ATB tooth grind. My Freud Fusion uses a High ATB and I really don't change my blade much at all. I'll use it for plywood, softwood, and hardwood. I typically only change if I'm doing a dado, rabbet, or spline(which needs the flat top).
      Hope this helps. If I missed something or have something wrong, others can feel free to correct me.

  • @davexee270
    @davexee270 7 ปีที่แล้ว

    i had a same problem after doing the arbor i done the teeth on the blade in a similar fashion...changing the bearings throughout then putting a very fine grit whetstone (i remember 3k on both sides of the blade at the same time and then putting fine grinding paste on a flat true hard metal on both sides and it came out very close to zero after of course balancing the blade to zero

    I'm troubleshooting a recent saw issue after a tablesaw mishap that has left my saw cutting oddly. I'm looking at this to be the worst case scenario, when you had it at .0004" do you really think four ten-thousandths is out of spec? It seems a bit excessive to me. That's less than half of one thou, unless I somehow forgot how decimals work (quite possible). Anyway, I hope I don't have to go this route but thanks for showing me how!

  • @Patescot77
    @Patescot77 ปีที่แล้ว

    To correct my run out I affixed sand paper to a blade stabilizer. I put it on the arbour and secured it to a board on the table. I turned on the saw and pressed the stabilizer into the arbour. The stabilizer approach ensures flatness and 90 degrees to the screw part of the arbour. I was inspired by Mathias.

    Again, a great video! I've got a kind of unrelated question regarding one of your older videos and I figure since this is the newest video the chance of you seeing it might be the highest, that's why I just post it in here. You once said that you took off the rust of some of the handplanes you got at garage sales. I wonder how you did it. Did you also grind it off with a stone or is there a more "sophisticated" method? I wish you all the best for the coming year Matthias! Greetings from Germany.

      @DumitruUrsu 9 ปีที่แล้ว

      +Thomas Huber If you have stuck parts (I had on mine) it's worth trying to heat it - probably in hot water(or motor oil). I "unstuck" some of the screws with ABRO 80 (kinda like WD-40) but it took a while. A friend of mine suggested submersing it in diesel fuel with the wooden handles removed (but don't heat this, you don't want a fire).
      On the rest of the body and the blade/chip breaker, I used fine sandpaper, 800 and 1000 grit, and water. if the rust is bad, you may want to start with 600, or 400 and work your way up. Put the sandpaper on a thick piece of glass, or other flat surface.
      Then wash it, dry it, on oil it well ;)

    • @DumitruUrsu
      @DumitruUrsu 9 ปีที่แล้ว

      I wouldn't try it nonetheless. This friend of mine said to leave it to soak in diesel for 24 hours, and the rust will just wipe off. Electrolysis sounds like a good idea, but in my experience it didn't work that great. and it was kinda slow too (I did it on some badly rusted hammers, though)

    On a 1983 Sears contractors saw, I tried using a sharpening stone to dress out the .001" wobble on the arbor, but it didn't seem to take off enough material. That .001" wobble on the arbor turned into a .005" very visible wobble on the blade. I removed the arbor and asked a machinist to true it on his metal lathe. The blade now spins perfectly.

    Oh the irony! I was attempting the very same improvement to my Powermatic 66 when my Baldor 3 hp motor blew. Tripped the breakers, a puff of smoke and that was it. New Start and Run capacitors are not the fix, so I'll break it down and see if I can be as resourceful and pull a "Matthias" repair. Fingers crossed! I miss my saw.

    Thanks for the video Matthias. Is there any reason this couldn't be attempted on the skilsaw worm drive table saw? Is it preferable to take the flange out of the saw to turn it on a lathe?

  • @mevk1
    @mevk1 9 ปีที่แล้ว

    Your jig sanding on the arbor looked very wobbly. Do you think some sort of jig to keep you perpendicular to the arbor may have helped slightly?
    You used a different technique (moving saw up and down) with the 2nd more aggressive stone. I would think keeping arbor fixed, your 1st method, would have been better.
    Still, As you mentioned half a thousandth is way better than the POS that Delta gave you, and quite possibly the best that saw can do. Nice video, thank you again!

    @MattsMotorz 9 ปีที่แล้ว

    You will never have anything be completely run out free. A half a thou is excellent eccentricity, even from metal working standards and it there is no point trying to get better than that, especially for wood working. That is such a small amount of run out that you could very easily cause MORE run out by trying to make it better.

    • @beanMosheen
      @beanMosheen 9 ปีที่แล้ว +1

      What sucks though is that 1 thou at the arbor is 15-20 at the teeth.

  • @vernmitchinson2013
    @vernmitchinson2013 9 ปีที่แล้ว

    Matthias Try a Diablo blade. I did and am very happy with it. It runs true, smooth and cuts very smooth and easy. It is an 80 tooth thin kerf blade. For your box joints it is too thin but for everything else you will be satisfied.
    I will not be buying any other brands in the future. Its expensive to be poor. In other words cheep crappy tools cost more in the long run.

    • @allananderson5840
      @allananderson5840 7 ปีที่แล้ว +1

      If I carefully watch a thin kerf blade on even 1" oak... it appears to widen from vibration with feed pressure/movement. So the kerf widens and contracts with feed rate. Nice for low HP saws but my 3 HP unisaw never lacks power really. So I avoid thin kerfs.

  • @claeswikberg8958
    @claeswikberg8958 9 ปีที่แล้ว

    never thought i'd say this in a wandel video but your solution was not complex enough ;)
    if you use a grinding bit chucked in a spindle and lock that in a jig, you could true it up and use it to grind out that last little bump. preferable the jig wouldn't rely on you pushing it into the flange by hand, but rather using a magnetic base to secure the jig to the cast iron table and feeding the grinding stone with an adjustment screw.

    Hello Mathias! Could You explain or show the work mechanism of the delta circulator's ruler?

  • @MyRadDesign
    @MyRadDesign 9 ปีที่แล้ว

    I would suggest to mark the high spots on the arbor with lines that extend all the way across the face, then draw a continuous band all along the outer face of the arbor where it will contact the blade. Lightly grinding at this point will show you where you are removing material with your setup vs where you want to remove it. Vibrations in the arbor when running will limit your ability to get it to be the desired conical shape.
    As for why Delta or any saw maker can't hold tighter tolerance, manufacturers make products by specifying tolerance levels on the components they are made from, and only check a portion of them to verify that they are to spec. They cannot afford to expend as much time as you can to achieve close to perfect operation, as to do so they would be too costly for most of their customers.

    I think it is as close as you are going to get it, the problem may be in the bearings .0004 is better than the tolerances of your bearings.
    may be you could locate some ABEC 7 or ABEC 9 ceramic bearings they would add the precision you are looking for.
    then you need to think about balance and harmonics. great video keep them coming.

    Thanks Matthias, two wobble related questions if you would:
    1. Is there any point doing this with the arbor on your home made tablesaw v2? I know it'll never be as good as a cabinet saw, but could it be improved?
    2. My drill press has some wobble too. I can't think how on earth I can get rid of it. Any advice?

  • @mars1952
    @mars1952 7 ปีที่แล้ว

    Nice work. You could have ground the outer flange the same way you ground the arbor flange. Bolt the flange on the arbor in the reverse position to grind it. I am going to do this to my table saw but I am going to do both flanges with a convex grind like @boksbox suggested and I am going to flatten the grinding stone first.

    • @matthiaswandel
      @matthiaswandel  7 ปีที่แล้ว +1

      there's no guarantee the flange will lie straight when you do that (no good reference surface) so you may end up grinding much more than necessary. The sandpaper is much better.

    • @mars1952
      @mars1952 7 ปีที่แล้ว

      Matthias Wandel yes, that might be a problem. I am planning to check the run-out before I do any grinding. My Uni-saw is older and much more robust than yours and I am not anticipating much run-out or much deflection. Thanks for the ideas.

    Had you tried replacing the drive belt with one of those "linked V belts before your grinding process, and was there any noticeable difference ? They are marketed for noise reduction and vibration reduction.
    Just curious as to whether they make any impact on difference at all.

  • @kbo8029
    @kbo8029 8 ปีที่แล้ว

    I apologize if this has been covered elsewhere and I know it's an old video. I'm new to wood working and need to upgrade from a table top model I bought for home renovations.
    I was looking at the Delta models carried in the big box stores and wanted your thoughts on whether overall Delta's were worth getting? I'd like to avoid paying 100$ for shipping for a better model. The one I was considering would be the 725, another downside being stamped steel wings?

    • @matthiaswandel

      Seems like a cheaper version of the 5000. I'm right out of college and new to woodworking so I'm less worried about the power to chew through thick hardwood than getting the accuracy lacking in table top junk.
      Recent reviews I've seen all seem good but it's always hard to tell if they're applicable and Delta seems to have a bad rap.

      like Mathias said I too just don't want to take it out of its home and to have it replaced. Having to measure the fence against tge front and back of the blade is annoying as well. I'm planning on getting a better fence soon. it's really such a shame cause I like the fence other than the fact it won't stay square lol

    • @JustMakeIt
      @JustMakeIt 9 ปีที่แล้ว

      +Art Connolly I have the R4512 and replacing that POS fence was the best thing I did. I replaced it with a cheap t-square fence, but it's still way better. I plan on making Jeremy Schmidt's fence some day which is worth checking out if you can weld.

    • @cncwoodworxroc6881
      @cncwoodworxroc6881 9 ปีที่แล้ว

      Own a r4512 myself. Was fortunate it was true using a dial indicator straight from the box. I did replace the fence shortly after purchasing as the factory one is junk. My personal favorite is the Inca fence for accuracy and repeatability. Since its lead screw driven, even post movement the fence can be set to nearly the identical dimension easily. (no plug for them intended, just my personal experience )

    Whenever you buy a tool today you are not buying a Quality controlled product you are buying a mass produced overlooked product from a company name that has a very close eye on its wallet and nothing to do with the product it makes. It has its limitations but your home built table saw is as good a one of the plastic saws!

    Great idea. Thanks! Must do the same with a small Bosch saw, which is truly junk except for the sliding carriage, which I took apart in brave youtube fashion, and shimmed with bits of veneer to run parallel. With two dowel segments screwed to it, a box with two holes plops into place instantly, and I can cut repeated small parts, or incrementally bigger, with a micrometer held in with little blocks glued here and there (the magic of hot animal glue), using its handle as the depth stop. Cheap & fast
