The thing with bench-mounted power tools is, they tend to take up space! That’s not a problem if you have unlimited space, but if like me, you don’t, then this might be one possible solution!
This is a rotating circular wood disk riding on rollers on a workbench surface. These wheels help the table turn freely completely around. The pivot in the center of the wheel is a hollow threaded pipe – hollow, because this allows for the wheel to be tied to the desk without lifting or shifting, and a power cable passes through it to a plug-box or power point mounted on the wheel to supply power to the tools you choose to mount on it.
I used a hollow pipe that was threaded on the outside for the axle, and fitted it through the top of the work bench using washers and nuts top and bottom to make it immovable, and then another washer and nut above the wheel itself.
As you can see, I chose to mount a bench grinder, a drill-press and an angle grinder cut-off saw on the wheel. The idea is that all three tools occupy less space, and yet the same space – and when you want to use one of them, you simply turn the wheel so that tool faces your working position.
Of course, you can’t have the wheel turn right round and round – the power cable running down the axle will break eventually – so you need to improvise a stopping mechanism, which I did by fitting a screw in the edge of the wheel at a pre-set position, and another one in the surface of the work bench! The idea is that at the extreme end of the turn, the two would act as a stopper so you would turn it back the other way again to use the other tools.
Sometimes while working, say while cutting a pipe or while you’re pressing an object against the bench-grinder, the tool might move to the side, turning the wheel – and you can stop this by adding a ‘brake’ to the wheel. I did that by fitting a moveable flange that pressed against a screw fitted to the wheel, to hold it in place.
It’s important to measure and lay things out as you see I did in the photos – you don’t want the wheel to be too small, or too big for the workbench, or for it to be off-center and too close to the wall behind the workbench for example!
As you can see from the photos, I removed all the plugs from the power tools and connected them to one plug – I did this because well, you’re not going to use more than one of them at any time anyway, but you could clutter the interior space up further with adapters if you prefer!
I’ve used this set-up for a number of years now, with no issues, but if I can suggest one improvement, it would be to cover the roller or wheel wells above, to prevent metal sawdust or other objects from dropping through and fouling up the wheels. Similarly, I’d also recommend some kind of skirting around the circumference of the wheel to prevent grit and obstructions from creeping in underneath. Otherwise, all good – and it’s a great little space saver!
