The magnets should be fitted in non-ferrous surrounds such as aluminium, stainless steel or
titanium. The trigger wheel is normally made of the chosen material but various users have
reported good results when the magnets are set in a suitable non-ferrous surround and the
surround is set into a ferrous material.
The magnets should be set flush with or slightly back from the surface of the trigger wheel or
surround. If set too far back the magnetic signal may be too weak. The magnets should be set
in place with a strong and durable fixing compound such as high strength epoxy, Loctite stud
locking compound eg 603, or JBweld. Some users rely only on the fixing compound but to
ensure that the magnets remain in place but many prefer that they be retained by mechanical
means such as peening, and this gives an added safety factor. Caution: Rare earth magnets
are easily damaged and the peening process (or location by grub screws etc) should be
very carefully carried out so as not to damage the magnets. If damaged they will not
have sufficient magnetic strength or may fail magnetically or physically after a period of
time. If installed correctly the magnets will have a long life.
