Digi Speedo Magnets

[Johnnybizzle]

Hi Guys,

Finished mounting my digi dash and speedo pick up ive now got the task of sticking magnets in place to the sprocket adaptor flange, got six magnets in the kit tried all six but way out on calibration, guna keep trying with fewer magnets till its right, does any 1 know how many to use and what spacings (equally i assume) to save me some time????

Regards jono

One magnet glued to the prop yoke with araldite. Two may be better and the gap as close as you can.

if you use a thing called a proximity switch (rs online) you can switch of almost any metal part

i have seen theaes used on motorbike in disc bolts to run speedo

come in loads of diffrent sizes and can be made real small sme are like a 1 inch m4 stud with a wire coming out

thay do need a 6-24v dc supply but v low ampage :)
