Briefly on my radial drill I had a pantograph arm fixed to it with a champher ing drill mounted on it I could change out the head and mount a hydraulic tapping head Now that was the meow of the cat The heads could be changed like the tooling on an aloris QCTP Drill the holes with a drill guide , flip the guide out of the way. T hen champher , switch out the heads and tap all of the holes without ever moving the part
The drill presses I have now do not currently have reverse but that is one thing I really need to change . I am also thinking that the handle switch that Almarghi made could be installed on all 3 handles but as momentary contact switches the forward position could be interconnected to a latching relay while the reversing position would break the contact and if held in the on position would run the drill in reverse then no matter which handle was at the comfort O'clock the switching control would be a thumb's flip away.
