    I'm not a sawyer but I am an engineer and as you were showing the waves in the wood I noticed that the waves were mostly coinciding with the knots in the wood. I say this as another person interested in all other professions/hobbies. As always you tell people in a way that everyone knows what you are talking about. Thank you.

    • @sawingwithsandy
      @sawingwithsandy  2 роки тому +3

      Thanks for that Ken. I believe the knots which are more dense than the rest of the wood causes the slight diving of the blade to be more obvious than other parts of the log when getting dull

      I cut primarily white pine and they have those knot clusters about every 3-4’ I noticed that the cut is typically thicker in those areas. I did have an issue with leveling as well on mine, although I have the bushlander which isn’t as easy to level.

    As much as the blades may be dull, slowing when cutting through the knot clusters will help prevent the waviness you showed.

    One other thing I found with wavy cuts ( on my HM130 Max ) is if I get too much gap in the blade guides with a dull blade it amplifies the issue. The blade guides do help to keep the blades from twisting and rising/diving. Great video.

    I have a HM126 and was cutting a big maple log into slabs a week ago. I knew my blade was reaching the end but thought I could squeeze one more log out of it. Wrong answer, it looked like a roller coaster. I put a new blade on and it was back to arrow straight and also much easier to move through the log. I will be changing out my blade more frequently from now on. Thank you for the video and your other videos. As a relatively new sawyer still learning the ropes I am always watching this type of video. I am sure I have seen most of yours.

I’ve been told this is one of the worst woods for that problem? I also ran without blade coolant for the first hour as per Woodlands instructions.

      @richardlee2488 2 роки тому

      The log will deflect as you release tension. If you cut a number of boards from each side before turning the problem gets more extreme. Either you need to allow for a truing cut later or turn after every cut is better but takes time. The conventional guides have also all but disappeared on commercial sawmills and are replaced by pressure guides which physically push the blade offline.
      The better mills and resaws are also fitted with blade deviation monitoring. The instant it happens its put right. A change of blade or feed speed through wild grain but it's just crazy to push on with a blade that's lost its edge.

  • @jasons.248
    @jasons.248 2 роки тому +1

    I think the greatest factor in the waviness of a dull blade is going to be wood grain which is most apparent when you come to a knot. Also, I did notice your blade guide wasn't in close to the cant, is it non-adjustable? If it was closer, it might help a bit, but you're obviously right with your assessment that most of the issues stem from blade sharpness.

  • @lawriestewart6377
    @lawriestewart6377 2 роки тому +9

    Like your Videos. From an Engineering perspective, I think the adjustable blade guide should be much closer to the log than you have it set up. This way it has the potential to reduce the blade flex that my be created by blunt teeth or knots etc. Just my thoughts.

    • @sawingwithsandy
      @sawingwithsandy  2 роки тому

      Good point. In the video the blade guide is as close to the log as possible. Although some manufacturers have blade guide rollers that contact the blade, in my case the blade guides are really close to the blade but don't actually touch the blade while cutting (at least they shouldn't unless the blade deflects a little bit)

    Sharp blades are key for everything. Sawing, surgery, cooking, etc. Most important kitchen tool I own is a knife sharpener. More cuts can be attributed to a dull blade. I did notice when you used old blade, even from a distance, how the sawdust was blowing out intermittently on the side, revealing the high spots in the board. Then when you changed blades, the sawdust blowout was consistent. It cut like it was butter. All the extra steps you take on everything, makes a big difference in the end. Kudos on another nice video Sandy.

    Yes, you can really see the waves as you were drawing the carriage back to the start position (at 5:50 in the video), while the blade hovers over the wood, the gap fluctuates like crazy. When I see that happening (outside of tolerance), I change my blade for sure. Thanks for the video! Cheers.

    Same thing on my Norwood LM30. Once my blade gets dull, i'll start seeing the wavy cuts. Over time, I've learned to notice two things that tell me the blade is about to be dull enough to start doing this.
    1 the head get's harder to push.
    2, I'll start seeing cut lines across the cant as I do the cut.
    Once I notice these two things, I start looking for the wavy cut and once I see it, I change blades.
    Sometimes, I'll get 3 logs before this happens, sometimes it's on the 5th log.
    Many variables affect this. The type of wood. The size of the log. How long has the log been cut.

  • @joesinakandid528
    @joesinakandid528 2 роки тому +1

    So Sandy,
    If the heated blade changes tension through expansion then in my pea sized brain the real answer would be to rely less on final tension with the torque wrench and rather re-design for a final tension relying on a 'blade tensioner' using a spring. In our modern vehicles we all rely on proper tension for the serpentine belt being regulated with a 'belt tensioner' which compensates for varying belt conditions (ie belt length fluctuations due to temperature changes or even just some wear over time). All that Woodland Mills would have to do is spec-out a tensioner and use the existing system to get close to final belt tension before switching to the new belt tensioner.
    Just a thought, Sandy, just a thought. Something like that would seem to be well worth offering on any band saw blade mill as a useful option.

    On my hm130max, waves, blade tension loose, dull blade, pushing to fast especially thru knots, log deck not perfect, portables mostly, blade guides adjusted properly to much gap allows blade to rise an fall. Drive belt an follower belt need replacement. Also more on portables use level on saw head mine would move after travelling. I used 6 inch torpedo level parallel to the uprights on saw head, adjust as needed tighten bolts up after .These problems tormented me before I rechecked everything after moving. Your channel is perfect for these mills keep up the great work.

  • @carlmclelland7624
    @carlmclelland7624 2 роки тому +5

    VERY interesting video, Sandy. You're actually dealing with Several different factors here that show up as waves in the cut lumber. I also saw in the video, the blade waving when it encountered a knot. This would indicate to me, a change of density in the wood fibers. Your blade, like any fluid, will travel the path of least resistance; as governed by the mechanical tension on the blade. If you could, please comment this, and list the distance between blade teeth, and the velocity of the blade in feet per second, or minute, whatever spec you might have. (I need this to run some calculations).
    I don't think heat would be a factor unless the blade gets extremely hot during cutting. The coefficient of expansion for (generic) steel is 0.0000065 inches for every degree Fahrenheit temperature change, or one one-hundredth of a foot in one-hundred-feet for a fifteen degree temperature change. (In other words, minuscule in this application). The only way I can think of to test for this is (one) measuring the blade temperature and (two) measuring the tension (torque) on the blade during cutting. Another way to test for this would be pushing your worn blade very slowly to prevent heating, and see what happens. A final way that 'might' work to test this theory. Make a cut with the worn blade at 25 foot-pounds torque on the blade, immediately increase the torque (say 35 pounds) and make another cut. Is the cut straight on the second cut with the same blade?
    Another factor on the worn blade would be the relative sharpness and pitch of the individual teeth. When you sharpen your blades and reset the tooth pitch, do you notice a difference between teeth that pitch 'UP', versus teeth that pitch 'DOWN.'
    If you could comment with that information, I'll run some calculations and see if I can find an answer. (If so, I'll email the results. They'll be far too lengthy and complicated than another comment post). THANKS for the challenge, buddy!

BTW my hm122 has the same style of belt tensioner as yours. First time I used a tork wrench to set it and marked the position on the shaft and housing. After that I just tension to the mark . I have replaced several blades and never had to make a tracking adjustment. Also you can make fine tension adjustments to adjust the tracking of the blade if you need to without massing with the mechanical adjustments. Great channel. Keep up the good work!

    I also run a HM130 Max but I cut large cherry, oak, maple and walnut. It seems that the larger diameter trees (+20") and knots cause this wavyness. I've had brand new blades do it on wide logs. I've resorted to cutting extra thick boards just because I have to run it through a flattener which sometimes takes off 1/4".

  • @SuperRistopaha
    @SuperRistopaha 2 роки тому +5

    Hello Sandy,
    I have been sawing on the same model this summer. One more way you can notice that the blade is getting dull (can be seen in your video also) is the sawdust is finer and comes out of the opening in the blade compartment with more speed when the blade is sharp. As the blade gets duller the arc of sawdust is shorter and there is a tendency to get the opening clogged with longer (non cut) wood fibers. I imagined that the wavyness comes from the fact that the blade getting dull happens at the cutting points pointing up and down or away from the centerline of the blade. This basically causes the blade to not cut but rather rip the wood at the cutting edge of the blade and therefore it will not empty the kerf voluntarily. Now that is is doing that it will go the path of least resistance, that is to where the wood is softer or more easy to cut. After going off track for a little bit a lot of tension will be created forcing it back the other way, but because it is not freeing its own cutting path it will continute past the proper cutting line and dive into the other direction. Of course there is a bit of randomness in that you might be hitting hard or soft spots and changes in grain direction etc. during this. But I have pictured that this is the problem, the blade not clearing its own path properly and therefore wondering off it. These changes in tension due to waving up and down are probably a lot more than a bit of temperature change could cause, the wood and the water are cooling quite efficiently, I have not noticed the blade getting warm. Another great way to keep track of your blade wear is to follow the cut quality at the exiting point of the blade out of your lumber. It will pull fibres out if dull, if sharp you get a nice clean edge. Just my two cents! Greetings from Finland!

    We ask these questions. 1. What is the typical life of a blade before it is dull. 2 are your logs dirty? 3 Is one of these mills worth buying? You can buy alot of lumber for $7k. 4 Do you plan on selling it or just using it yourself? You can use anything. You cant sell everything. 5If you are building a house ,do you want to saw or do you want to build? you cant do both. I sawed lbr. for my outbuildings. I bought the lumber for my house. Remember your lumber is green,not dry.7 if dull the blade will waver on knots. Knots are harder. Spruce knots are very hard.

    It can also be the heating under use which causes the blade to stretch during use, this happens with cheaply made blades which inferior metal was used in the manufacturing.
    Breaking can also become an issue with cheaply made blades when the blades are really cold from the weather and then the blade gets hot quickly under use.

    Wow I learned a lot on this one! Thanks for all your info on this topic! I’m definitely keeping all these things in mind going forward. One thing I noticed as you were sawing with the old blade vs the new Sandy, was the sawdust exiting the mill.. old blade had minimal dust flying way out and to the side.. it was basically from what it looked like, just falling out in clumps somewhat as you were going.. maybe this was due to something like rain on the log before hand but nevertheless it’s something I wanted to point out.. the fresh blade.. the sawdust was flying right out of it and way out to the side. Also, a thought that I had on the waves in lumber, I agree with all your points but to if the old blade is having a hard time keeping up, it may also be trying to go to the path of least resistance in the lumber so that could potentially appear as waves maybe along with what you said as well.. just wanted to throw out there.. but totally may not be that all.. anyways thanks again for having us over, cheers!

Reasoning sounds good but am wondering (the question part) how it would work in the real world to help with correcting wavy cuts.

      Hey Jack! Good questions. I haven't tried the 1.5" blades as my 1.25". blades have cut good and flat consistently. However, I wouldn't be opposed to 1.5" blade but my main question I have is whether it would be any better than the 1.25" since a 1.5" blade would leave more of the blade unsupported by the band wheel belts. It's certainly something I'd want to try in the future though to see if there's any difference

    Sandy I cut pine here in Florida and I got to ask with the new sawmill how do you like the loose belt on the follow pulley for the blade? Personally I think it's a horrible design after I cut two or three pine logs the belt starts to get a little bit sticky build up at the top and jump my blade off. It's fine when it jumps to the outside but I've lost three brand new blades because it jumped to the inside. Do you have any suggestions or did you ever have this problem with the older sawmill?

I ended up using next to no water to cut and haven't had my blades jumping off much at all

  • @Propsman416
    @Propsman416 2 роки тому

    The harder wood surrounding the knots is causing the blade to deflect. It's like starting a cut into buttery pine and then suddenly hitting a patch of hard maple. A brand new blade can overcome this drastic change, although you will no doubt feel the cut speed slow, but no blade will remain sharp enough cutting through knot after knot. Additionally, the whole blade isn't going through all the knots for the same period of time, so the blade is dulling unevenly. Add to that the sloppy distance of the guide bearings from the work piece, and the blade ends up fluttering up and down giving you those waves. If that's as close as the guide bearings can get to that log then it is definitely a design problem that is compounding the waves. Also, as you mentioned, blades do stretch, so it's a good idea to recheck your tension once you've been cutting for a while.

    • @sawingwithsandy
      @sawingwithsandy  2 роки тому

      Thanks for your insight. I think if the blade were to be running against the blade guides blocks as is the case with blade guide rollers then I’d agree that having the blade guides able to move closer to the log would be ideal. However in this case since the blade guides don’t actually touch the blade I’m not sure if the more would be a noticeable difference

    • @Propsman416
      @Propsman416 2 роки тому

      @@sawingwithsandy With the guide blocks, as opposed to rollers, the blade still rides against the blocks, but only when it has been deflected into doing so. The guide blocks act as a "stop" limiting the abound the blade can get deflected in either direction. If the blade is properly tensioned it would, theoretically, bounce off the guide block and then once again find its equilibrium between the guide blocks and resume running true. But, if the space between the guide blocks is too great, the blade will wander too far back and forth and produce the waves. Similarly, if the guide blocks are set up too far away from where the blade is in the work piece, the blade will wander too far, as you are only limiting the flex way out past the piece of wood being cut rather than where the blade is doing the work. The 1/16th" of travel space between the guide blocks can end up allowing 3/16ths of an inch in flex in portion of the blade that is in the middle of the wood. A 6 inch open span of saw blade with 25ft lbs of tension is going to flex a lot less that a 20 inch open span of saw blade with that same 25ft lbs of tension.
      The blade is always going to follow the path of least resistance. What exactly that path is, is a result of how sharp the blade is, the character of the wood, the tension on the blade, and the amount of flex in the blade due to how much of it is supported vs unsupported inside and outside of the cut. The sharpness of the blade makes a huge difference, as you rightly point out, but the other factors still apply. If the blade is sharp enough and has tension on it the least resistance will be in cutting straight through the knot. As the blade dulls, it will be more likely to wander rather than cut straight through the knot. Increasing tension may help it run straight again, but that's because you would be changing the path of least resistance. Too much tension and you could see your wood burning, as well as put too much stress on your machine.
      Knotty wood will mess around with any blade, and you touched on the fact that the blades are likely unevenly sharp as a result of hitting knots.
      Anyway... I really enjoy your channel and appreciate all the videos and tips you provide us with. Please keep it up.
