Those brushless Consews are annoying to reverse, like for threading, because you have to go through the settings on the menu to do it. You can hack it with an Arduino but it’s not instantaneous.

I have mine with footpedals for speed and direction which I like but it can be kind of clumsy.

A DPDT toggle switch can be used to switch two of the motor leads and that will reverse most brushless motors.
Could just put a small mini box in a convenient location and that will reverse it without an extra foot pedal.

If that mod were done I would be careful not to hit reverse while the motor was still rotating.

Yes Reverse is a pane, especially the first time if you did it often I do not think it is that much of a problem.
I have been "thinking" of some sort of switch.

Of course I would like to have automation, controlling the spindle speed with a micro and
DS1803 (digital pot) and then Reverse using Mosfets.

Another problem is stopping the spindle, there is no instantaneous stop, there is a large capacitance
that needs to be run down before the motor stops.
Actually when I move my manual 10k pot down the motor stops more quickly so there might some
reversing in the control box.

It would be nice to have a schematic, I really do not have the time to reverse engineer the
control box.

It might be simpler to do away with the Consew controls and substitute a
ESC (Electronic Speed Control) of course I do not know the motor voltage,
I suspect they might be 110v.

Still, for the total cost of both motor and speed controller which is quite low I think it is
a viable alternative power source for a power tool motor.
