Tell us about yourself!
Drill a hole in a block of Aluminium or something else hard with a clearance hole perpendicular to the base & the same size as the tap. Hold it hard against the work & start your tap, once you are in a couple of turns you should be right.

Hi, very impressive. If you don't have access to power you could rig up an old bicycle & treadle power it instead of an electric motor. Put the kids to work lol (or your partner) . Good exercise too. Plenty of old bikes thrown out on hard garbage council collection these days.
Great idea, I am always loosing my chuck keys. I have been a computer tech for 30 years & have stacks of old hard drives lying around, we use these magnets for fridge magnets,but never thought of this, what a dummy. Seeing that is a Hafco drill you must be an Aussie!
Of coarse you would need to balance it some way. I could also just be a smaller frame with a couple wheels on the side that extends out but still attached to the Bench drill frame.
Why not have the Bench Grinder on a sliding rack that can come out either side & slide back when finished. You could even have it swing out & up if you didn't want to bend over to use it.
