A few years ago I got a ‘Mini table Saw’ from Mr Ali’s express. Similar to the ones you can find here
It came with a chunky and (so far) reliable 9->24 adjustable power supply and a bunch of accessories:
I’ve used it quite a bit now; mostly for cutting pieces for boxes and rough sizing prior to laser cutting. so here are my thoughts:
Build-wise it is just fine; simple but strong; all pressed steel, sturdy bearing mount, a 775 series 24v dc motor with a belt and ‘loosen the motor mount and slide’ adjustment. The simple guide and guards it came with are OK, but only for simple and small jobs.
The big negative is the lack of adjustable blade height; and I’d recommend going for a more expensive machine with some sort of blade adjustment if you can.
I have made some ?sensible? improvements; firstly I have enclosed the dangerously open blade chamber and motor electrics in some acrylic (which I cut on the machine itself, of course.) There is a magnetically closing hatch for the blade chamber, and I fitted a reversing switch to the motor. There is a attachment point for my ‘shop vac’ that somewhat helps with dust collection.
I made a base plate that the unit sits securely on, and is easier to clamp to my workbench. It has a rest for the sanding wheel, and accommodates the drill too. The flexible drive drill is really useful for some jobs, but spun the wrong way until I added the reversing switch 
I also made a saddle for it, running in the slot for the original ‘guide’. I put some effort into this, the ends are laser cut to shape and there is a t-nut slot for the clamps, thumb guard, and big scary warnings.
- It also has a removable ‘lifter plate’ that goes underneath it and reduces the cut height to something more sensible for most jobs
I have used this for some large jobs too, I took the photos above after cutting some big lengths of inch-thick mdf.
I’ve also cut aluminium sections to length (using the wood blade on slow speed…) and quite a bit of PCB too, which I use the cutting disks for. And a good face mask.
Negatives;
- It is hard to find blades other than wood working ones in this size.
- Has definite limits; size wise and power, it is fast with that motor but doesnt have huge torque.
- Tablesaws scare the ***p out of me… I give this a lot of respect once the blade is spinning.
