please do a build thread on this?
Im not sure its worthy of a thread but I will post in the made today thread. It will be a 20mm OD, 15mm ID acetal tube, a single magnet stuck to a shaft that slides inside the tube. And a 40mm nylon washer on the shaft to stop swarf following magnet.
I think these 15x8mm magnets might be much stronger than needed, the 8mm dia x 25mm may have been a better option

Im thinking it would be useful a long flat one for sweeping the floor to clean up swarf or grinding dust.
