Building A Tiny Table Saw

If you want a regular table saw, you’re probably best off just buying one—it’s hard to beat the economies of scale that benefit the major manufacturers. If you want a teeny one, though, you might like to build it yourself. [Maciej Nowak] has done just that.

The concept is simple enough; a small motor and a small blade make a small table saw. [Maciej] sourced a remarkably powerful 800-watt brushless motor for the build. From there, the project involved fabricating a suitable blade mount, belt drive, and frame for the tool. Some time was well-spent on the lathe producing the requisite components out of steel and aluminum, as well as a stout housing out of plywood. The motor was then fitted with a speed controller, with the slight inconvenience that it’s a hobby unit designed to run off DC batteries rather than a wall supply. Ultimately, though, this makes the saw nicely portable. All that was left to do was to fit the metal top plate, guides, and a suitably small 3″ saw blade to complete the build.

We’ve seen mini machine tools like these before, too. They can actually be pretty useful if you find yourself regularly working on tiny little projects. Video after the break.

    1. And what? he has 915K subs (+1 with me now). So you can grow without being silly, narcissistic and diverting an Apple product ?

      Of course you can and if you can’t, that’s not an excuse to reach to the bottom.

  1. “800” watt motor in a small sealed enclosure. No overtemperature cutout. Clearly for low duty cycle work. But maybe that little belt (GT2?) is the safety fuse — maybe it will fail before you can load the motor to overheating, or get the enclosure to ignition temperature. Clever.

  2. commercial options exist- MicroMark and Byrnes used to make hobbyist specific mini table saws. but boy they are for “serious hobby” (AKA $$$$). Best I ever did was one of those adjustable blade guides for stripping my own project lumber from sheets. Was surprisingly good.
    But I wish I had the cool mini table saw

    1. Harbor Freight has a mini table saw too.

      I’m not sure what all the “battery speed comtroller” talk is about, DC “speed controllers” are available from $5-40 many places. Also DC power is DC power, the speed controller doesn’t care if it is battery or converter supplied

  3. Great build, but as that is still a serious blade with plenty of torque behind it and some heavier feedstock (the aluminum) shown, there should really really really be a riving knife.

    1. In my many years experience with a table saw, the riving knife, one-way pawls and blade cover have all caused more injuries and damaged stock than a naked saw. It’s dangerous, sure, but a drill press is a far more injurious machine.

      1. I agree. I have a lot more respect for my table saw because it doesn’t have any safety features. I go through a meticulous process every time I use it to make sure I don’t get hurt.

        Most important thing, use an inverted pistol grip style push stick.

    1. At the moment I have another Proxxon table saw on lend. Fet / 27070 which is a bit bigger model, and I don’t like it much. The inside looks quite well built, it does have a quite smallish motor, but these things are not made for high power stuff, so that’s OK.

      But I don’t like the accessories for this saw. They are very flimsy and not accurate. Also the guides built into the saw are made of wobbly plastic that bends too easily. Lookking at the price, it’s not on par with it’s quality. I would have expected better quality acessories and built in guides for that price.

      Overall, if you’re interested in a small table saw, I recommend you buy a regular circular saw, and then make a small table and make a bracket to mount the circular saw on the bottom. Add an extension cord with a built in switch and you can turn the saw on and off from a convenient position.
      On top of that, there are quite a lot of very simple hacks to extend the possibilities for hand circular saws. From long tracks, to various wooden squares for easy 90 degree cuts and more elaborate angle instuments or tracks. You can also plunge cut in the center of big sheet of plywood.

      A hand circular saw is probably one of the most universal electrical saws out in the wild.
      It’s biggest limitation is that it can’t get into corners. To get into corners a jigsaw is better suited, but I don’t like their vibrations and noise (Circular saw makes more noise, but somehow I find it less irritating). It’s also nearly impossible to saw straight with a jigsaw, and for corners, using a handsaw at the end where a circular saw can’t reach is plenty good enough for most DIY.

  4. If the saw is strong enough to move the piece, it is strong enough to drag your wayward appendage past the blade faster than you can regret it. A riving knife helps stop the material from closing up behind the blade, which makes it harder for it to lift and drag the piece. If you’re working with pieces this small, just acquire a benchtop jig saw. The vertical cuts will be cleaner anyhow, due to smaller workface and no horizontal actions.
