Refurbishing a B&S Magnetic Base

admin

Some while ago, I inherited an old (1950's?) Brown and Sharp Model 750D Magnetic Base.Its magnetic pull has decreased over the years so it needs to be re-magnetized. I just got off the phone with the Hexagon Corp. which owns the B&S brand; after talking to three people who didn't even know what a magnetic base was, I finally was told by the service manager (who also didn't know what one was or was used for), that they don't service them.Usually I do things like this myself, but thought it might be easier to have the refurbishing done by someone else, for a change; guess maybe not, based on the call. I don't have time to do this for a while so thought I'd ask for good suggestions here, either about anyone else who does such work, or for the best way to do it myself, from anyone who has done so or knows how. At the moment, I don't remember the specific internal arrangement (i.e. the assembly method of the rotor) and have no pictures, but assume I just need to work on the rotor and the main block separately.Any ideas?
Reply:Not much different from recharging the magneto magnets on an old hit & miss engine as far as the magnetic end goes.You'll probably need to weld up a magnet specific core or machine one out, and then wind it with some damn heavy coils.  Generally the magneto chargers are wound with #12 or heavier wire.Then you just need to take the SOB apart set the magnet into the charger and put DC to the coil for a period of time.  Of course the kiddies at the manufacturer don't know what the hell it is, they wouldn't if it fell on their foot because it don't say CNC on the side of it.
Reply:Oh boy,Is it the one that looks like a coffin?If so it can be helped by a lift magnet while assembled (get the poles right).I'm having a devil of a time remembering, but I think it may have an internal keeper and the outside is the magnet, so when not being used the magnet is set to off (this is the opposite of split units with an internal magnet which are stored magnet on and clamped to a keeper).Matt
Reply:places that rebuild loud speakers have the equipment to re-magnetize magnets. they might be willing to help if you built the pole pieces . . . .-- fredLincoln 180C MIG
