Forget figuring out how to secure your workpiece with cumbersome hold-downs. Mount a magnetic chuck to your machine and all you have to do is flip a switch and start working.
Of course you’re limited to working with materials that are attracted to a magnet. In reality that will probably be some sort of steel — does anybody machine nickel? Plus you’ll have to have a flat base for the magnetic chuck to grab.
This 12″x 6″ Cen-Tech magnetic chuck from Harbor Freight gets you started for $99. They precision-grind the steel top flat to 0.002″. Engaging and disengaging the magnet just requires a simple pull of a lever (which is not shown).
Could a reader enlighten us on why it is called a chuck and not a table?
