    I use lower speeds on my sanding machines for old paint layers or other materials that tend to “melt” with the heat of sanding and clog up the sandpaper. Sometimes I lower the speed to have more control on small ridges or near glass windows.

    @PhoenixRevealed 2 года назад +65

    Hey James, interesting video. I have a single-speed random orbit sander and I've never felt I needed it to go slower. I just wanted to point out that moving the sander at 50% less speed actually doubles the time it spends on each spot, not 50% longer. The rule is Change in Time (over each spot) = 1/Change in Speed, so if you want to spend 50% longer on each spot (3/2) you need to move one-third slower (2/3) .

  • @Mike-bh7sh
    @Mike-bh7sh 8 месяцев назад

    Thank you for a well informed video.
    It is irritating to see so many videos out there giving bad advice on sanding.
    Yes, pigtails are simply the visible pattern of your sander. They are there no matter how you sand.
    If you sand to a high grit level then the pigtails are so fine you just aren't noticing them - but they are there - it is the sander's pattern.
    Badly visibly pigtails can be caused (as stated) debris under the pad (including corning from a finish or resin) or moving too fast (stretching your sander's pattern out - whatever the speed, moving to fast for that speed)... and bad sandpaper.
    Cheap paper will not have the same quality control as better paper and so you may have larger grits contaminating the mix.
    In any case (something not mentioned), why are people not sanding by hand for the final pass (unless you have a nifty inline sander)?
    We always finish with a hand sanding (we are only sanding to 180 or 220 normally).
    My routine will usually be to power sand to one grit higher than I want (so say 220). I will then drop back to 180 grit to do a quick hand sanding. This reduces the amount of time required to hand sand as you are not having to sand out the deeper marks of the previous sanding - you are sanding deeper marks... and removes ALL pigtails.
    For those who do not hand sand - I recommend doing a test board in your usual routine, and then do another board as described with a hand sanding to finish. Apply a stain (yes professionals are using stain ALL the time - another youtuber attempted to claim we don't), let dry, and topcoat. I suspect you will see a clearer more pleasing result in the hand sanded test board.
    I leave the sander at a highest speed unless I'm using a beast to shape wood and then I might bring it down to make it more controlled.
    I will turn it down when doing a wet sanding on finishes, reduces heat and so reduces corning... also do not want it to aggressive as I do not want to sand too fast and cut through.

  • @alastairstewart5527

    One thing I have found using an RO sander to sand small items like box lids. This can cause the edges to sand faster leading to domed lids. The outer edge of the disk moves faster than the middle. For every revolution the outer edge has further to travel to complete a single rotation. This can give some interesting features to a project

    @SAWimp1 2 года назад +8

    in cabinet industry speed settings are used in finish sanding. while some things are done by hand, as you suggested, large flat surfaces are done with ro. the speed settings are important because production finishes can be rushed and by changing the speed you are not just changing the rpm of the machine, you are changing the velocity of the orbit as well. velocity and friction are proportional at low speeds. less gumming of finishes that are not fully tacked or high in pigment content. it really is an important feature for working quickly in production finishing. even pneumatic ro sanders are variable speed.

    I bought a Bosch ROS20VSC recently. I just opened the box this weekend, put on some 80grit, and spotted the variable speed wheel. Then I did something rarely done by most, I opened the manual and there it was "for most sanding jobs leave the speed on the highest setting and only hold the sander, do not press it down onto the work surface with force". I joke but this is a necessary video for those that might have been using it for years or bought a used tool etc.

    It also should be noted that on regular, common sanders, the higher the speed, the easier they are to control because of the increased stability. Due to the mechanism of the random rotation, lower speeds can cause the sander to jerk around and be very difficult to control.

    • @tummytub1161
      @tummytub1161 2 года назад

      Hi everyone! If you are having troubles with a RO-sander jerking, here are a few things that can also be the problem besides speed settings:
      The sole isn't flat,
      The material has bumps in it,
      Or the sole isn't perpendicular to the material.
      Some machines have a bad balance. Check out Stubby's video on random orbit sanders, he is better at explaining than I am.

    It acn be noted that one reason not mentioned for a slow sander would be if you are using it for stripping paint. Slower orbital speeds means less heat which means more efficient cutting and less smearing/melting when removing an old finish.

    @RobertSandell 2 года назад +2

    This is the level of detail and explanations that I like and that few (if any) other channels do.
    I think though the actual reason for the non variable DW sander is at full speed is because both variants uses the same motor, and the speed selector is just a variable resistor. Put the speed selector on the highest number and there is no extra resistance on the circuit and it gets the same full speed as the other version. Put the speed selector on a lower number and it increases the resistance slowing the motor down. Same as the volume nob on a stereo amplifier.
    So there is probably less though put into what a good speed is and more about economies of scale ;)

    I've made a few wooden boats and paddleboards and during the process I'll need to sand epoxied surfaces. Just controlling the speed of movement is going to be a disaster. Sanding creates heat in the workpiece and if that workpiece is an epoxied surface the heat is going to start melting the epoxy which is not good. It'll also clog up sanding discs as well. Controlling the speed on the sander - I use the slowest speed - is an absolute must do. Oh, and Mirka Abranet sanding discs are the dogs doo dahs! This comment is not sponsored by Mirka :-))

    I have been refurbishing an old house lately, cleaning off the old exterior boards and repainting. They are New Zealand Rimu, which is about 120 years old, very dry, and very hard. I melt and scrape off the old paint, then sand to clean it. I found, by trial and error, that when using 40 grit disks, I needed to run the sander at its very lowest speed as even the best quality disks disintegrated at higher speeds - the backing hook-and-loop fabric parted from the sanding paper. This also meant a lot of cleaning of the hook-and-loop surface of the sander pad each time this happened. I guess the coarse grit and hard wood cause a lot of tension between the layers on the disk. Running at the slowest speed prevented this and also stopped clogging of the disk from remnants of paint and cleaned the wood quicker than using a higher speed, so the very lowest speed setting can be useful..

    25 years in the automotive refinish business. The only machine sanding is done on body work, and maybe prep work. Any sanding of base is by hand, as well as cured clear coat before buffing (although I do like a finishing DA for large sanding/buffing jobs).

    I've had my Dewalt RO sander for many years, never had one with a dial because why would you ever need that feature.. (It's all about adding a price point to the tool)
    Learn to control your speed, and you will get good results.. Also helps to work your way through the grits properly.

    As a new woodworker years ago, I purchased a random orbit sander, as I heard it was an essential tool to have in a wood shop. Alas, I was not aware of the variable speed function and purchased one without it. This is the only tool out of dozens that I've bought since, I regret purchasing.

      Don't regret your purchase. Instead...get comfortable and proficient with it. When you do...think about how much more skill you will have when it comes time to buy a new, variable-speed sander!
      As I spoke above, I only use the single speed tools. Just makes things easier for me. To each their own, right? No random-orbit sander, in and of itself, is really bad. Many problems and difficulties are on the operator...as sorry as I am to say that. Just grab a piece of wood, a pencil and a cold one and start sanding. You'll soon get the feel for the tool, and will learn how to get the most out of it.

    Thanks James for the deep dive on this topic. I like my Dewalt corded sander & always keep it set at 6. I also find that the two-handed sanding method is the most comfortable with this sander: one hand on the “neck” of the sander (not on the top), and the other hand on the dust extractor hose. I do wish that Dewalt would change the location of the variable speed dial. I find that I frequently, inadvertently, move the variable speed dial. Would I enjoy sanding more if I had “Team Green’s” ETS EC 125 or 150? Sure. Gotta sell a lot more workbenches to afford one.

  • @ARNM55-l9v
    @ARNM55-l9v 7 месяцев назад

    Interesting & informative video. When discussing sanders with variable speed controls you seem to have assumed that everyone just uses these type of sanders on relatively long pieces of unfinished wood. When sanding off some fillers, materials & sanding over old painted surfaces high orbit speeds tend to melt what is being sanded which clogs up the sanding disk.
    Physically moving the sander faster across a piece of material isn't always a realist option to control the number of orbits taking place in a given area. With the technology available today the user / consumer should be able to choose the OPM, with a speed control, that is best suited for their particular material or task. Not everyone has a wall full of specialty tools available to do a particular job better than a standard RO sander. I wish this message would get to the manufacturers.
    I'd bet the real reason that so many manufactures stopped building RO sanders without a speed control function is because it was easier & cheaper to make & not because some pseudo-scientific research on what speed the "average" consumer uses or needs to use.

  • @alfredklek
    @alfredklek 2 года назад +2

    I've worked orbital sanders out of my work flow almost entirely. I usually use bench planes clean up my saw marks which was what I was using the orbital sander for mostly in the first place. They do a better job and they do it faster providing the blade is sharp. I'm not entirely convinced, even, that powered finish sanding is any faster or more effective than hand sanding by someone who knows what their doing. The only time I use one is when I'm sanding decking plugs, but I'd probably be better off with a small belt sander TBH. The primary problem with an orbital sander is that it will always cut across the grain half the time and it will never look as good as wood sanded with the grain.

    I've been using ROS for 30+ years now. My first was teal. I spent a couple hours learning the tool and the difference between it and the quarter-sheet sander I was currently using. Thought a lot about the speed of my own movements and how much I "sat" on the sander. Did the 'pencil' trick multiple times to judge how rapidly material was removed. Got a reasonable muscle memory going on, and because of that, I use single-speed Random Orbit Sanders exclusively.
    I currently have two in my shop. One is teal, the other is neon green. Each has it's place and time. Teal is more for finish work on fine projects of solid and ply wood. Greenie gets abused...smoothing rough-sawn material, older reclaimed woods that may have embedded dirt, grit and gravel, and...wait for it...finishing off polishing old woodworking tools that have cast-iron tops.
    I use 100, 150, and 220 grits for 98% of my sanding apps. A minor step away from the 80-120-180-220 school of thought which allows my to skip a step in hardwood sanding, and two in softwoods. Rarely do I need to use 60-80 grit, and if I need a finish finer than 220, I'll break out the sheet stock and sand by hand.
    There's about a $10 difference between single-speed and variable-speed Sanders within a given brand. I buy a new RO sander about every 2-3 years. I take that savings and buy a $10pak of 60 grit which lasts 2-3 years...lol. I go thru about 3 boxes of 100...a box of 150...and a half of a box of 220 in that same time.

    I use my sander with 400 grit mesh to level my mohawk nitro lacquer on guitars. I have a craftsman, that's 12k i believe, it's up there with the dewalt but didn't have the dial. I think slowing down for using 400grit and higher grits could be beneficial for sanding lacquer on edges or sides of certain work pieces, as far as instruments are concerned.

  • @starfishsystems
    @starfishsystems 2 года назад +4

    I started out using my first orbital sander at top speed, pretty much for the reasons offered in this video. I wanted aggressive sanding over large surfaces.
    To my surprise, I found that the fastest cutting effect was at about 3/4 of the range. I don't know why for sure, but I had a sensation at full speed that the sander was almost floating on the workpiece, producing very fine sawdust rather than biting into the material. This was particularly evident on softwoods such as cedar and pine.
    Now I'm wondering if I formed a false impression somehow. I should go back and run some more tests using a micrometer and stopwatch so that I'm not relying on subjective impressions.

    • @gnarthdarkanen7464
      @gnarthdarkanen7464 2 года назад +1

      I know it's not a sander and doesn't seem even close... BUT it's probably relevant here.
      About a decade ago, I ended up with a chain-saw. It had the smallest tooth-set on the market, but someone had tinkered with it to over-rev' the engine... and it was funny, which was more why I bothered with it than anything... I knew that kind of arrangement would shorten the saw life.
      BUT... I sharpened the chain (something I'm quite used to on all chains, even the antiques with ENORMOUS teeth in comparison)... AND with a fresh tank of gas, I laid the cutting edge into a relatively ordinary length of poplar that had been laying in the yard for about a week... It shredded the bark fine enough... but then the teeth basically skipped uselessly over the wood at full throttle (the usual method for using a 2-cycle chainsaw... just squeeze and go)... Even engaging with the dogs and adding leverage didn't seem to fight the "speed-skip"... until I'd deliberately feathered OFF the throttle trigger, and running less than 3/4 full or so, where the chain near-instantly caught and dove right into the wood like a hot knife through butter...
      SO just before you dismiss your impressions... It IS possible that if your sander feels like it's "just floating" due to speed... It's possible you've just found a harmonic or whatever by which, basically, that's exactly what it was doing... floating or bouncing just about uselessly over the work instead of engaging and cutting into it. ;o)

    • @ScottCleve33
      @ScottCleve33 2 года назад

      I had the same impressions. It brings to mind an episode of Myth Busters where they tested if a car driving fast enough over rumble strips would feel the rumble less than someone going slower. In the end they found that if you go fast enough that you just go from one bump to the next without really hitting the low spots and getting the bump. I wonder if the same principle applies to sanding.

    some finishes clog the paper at faster speeds - slowing them down helps. Also smaller work that would otherwise fly across your bench can be controlled better at smaller speeds. (we sand small pieces of 3mm plywood!!!)
    Remember though the sander moves less in the center and has less than 100% coverage just outside the shortest paper radius from the offset so you're sanding in a square bottomed donut shape deepest just before the edge
