Can the magnet in a magnetic chuck be recharged if so how is it done? I have one that does not seem to hold well.

......and I assume if we're talking a mag chuck on a surface grinder, it would be a good idea to re-cut the chuck to eliminate any error from the "flip over"?
I learned something today, thanks Ray! atty I would say yes to that. Be sure to turn on the mag and grind with a open dressed wheel and lots of coolant. In some of the real old chucks before I grind them I use a sharpened pin bunch to lower the lead as I have found it will plug the wheel if it's off a few thousands. Be sure not to reef the T bolts down to tight as you can break the T-Slot and warp the table on the little machines.
Thanks, Ray. I have an old Kent KGS-200 that's probably 20 years or so down the calendar, and I'm sure the chuck has never been removed from the day the factory bolted it on. Never knew that a flip was in order. 'Nuther project to the add to the list.
I need a 6X12
Probably a dumb question but I'll ask anyway.
Could a 6x18 PM magnetic chuck be shortened to say 6x16.
Or , I just thought of this, how about milling the chuck face one inch on each end
below the surface to make the effective length 16 inch. How much lower
should I mill it down.
Reason for this is I have an Abrasive 1-1/2 manual surface grinder that
travels are made for a maximum 10x16 chuck. I was given a 6x18.
6x12's are common -a standard size. Check eBay. Also, I've seen some new manufacture ones at Shars and other discount houses in the $2-300 range.
