Found these people, missile motor services, based in Croyden, they zap ceramic magnets in the can for £1.50. Dont know if they can do HO stuff but worth a phone call. For an ultrasonic clean, comm true and precision balance all for only £4.75 we should all be able to do it in all classes, lol.
wast of time and money dont feel any stronger to me and all the motor mags naw force apart insted of pulling together
well you win som you lose some i will send them back to him and hopfally he will sort the motor mags out
Zapping magnets simply restores magnets to full strength.
You'd expect they started out from new at full strength, and may deteriorate a bit with age and use.
If the mags are more or less still at full strength, there's no point in zapping them.
Magnets should be zapped in the direction they are already magnetised. If the operator makes a mistake and puts them in the machine backwards the direction of magnetisation will be reversed.
Bat-Jet / BRP do a simple one, or you can build your own with the simple plans here for less than a tenner. You wont get a true calibrated gauss measurement, but you'll be able to match magnets and compare strengths.
Another way to measure magnet strength is one of these:
Blast from the past in terms of threads but Jon and I have been mucking about with Tycos so I was looking at some of the older threads for some advice.
Anyway magnet zapping. All well and good and it makes sense to me in theory but how do you know which magnets are deteriorated and therefore need zapping? How do you tell if they are deteriorated or were just weak in the first place?
Also, does anyone know what value in grams, a Tyco magnet new would read as?
For example my motor magnets variously read between 25 and 30 grams of downforce on an On Balance DK-1000 scale. Is that good or bad?
My traction magnets are between 12 and 14 grams.
Anyone have any idea what good values are?
