Someone asked for info on how I made the trigger wheel I sold recently so here goes.....

Take one Ford Sierra bottom Pulley



Remove the trigger part using heat on the trigger ring and some tyre levers



Trigger wheel laid on to mini 1275 bottom pulley



I fitted it separate to the damper by the following method (excuse the low quality paint drawings) its like a top hat with th top fitting into the damper recess



I got a mate to lazer cut out the following parts from 5mm steel plate



so I ended up with a disc with 5/8 hole in the middle and a ring

then assemble (sorry no photo) trigger ring with lazer cut ring inside then a piece of tube 65mm outside diameter with the disc on top

welded up then run up on a lathe just to tru it all up and painted



picture also shows longer crank bolt from minispares (note the allen key size is 1/2" imperial so not your usuall ones in your toolbox)

Finished item




welding could have been better but I personally ran it up to just over 6000rpm with no problems. If making again I would make the tube part slightly shorter as it was a little long and required the engine mount and lower rad bracket adjusting slightly

And questions just ask


Cheers

Ian

this is of great interest to me im just a little unsure what you mean , with no pictures could you elaborate please ?

also how does the special components and the kad kit differ ?

There are piccies, alas Udo's wheel involves some machining so not as home made as I hoped it might be. It is essentially the same as the other wheels you mention if not as pretty. I used a trigger wheels wheel on a turned down crank pulley http://www.theminifo...amp;hl=megajolt

so whats wrong with the premaid ones as id rather buy pre made. ?

i say this cause i was told the trigger wheel isnt right for the mini , is this true ?

Nothing wrong with them at all - just the cost!

Any 36-1 wheel will work, I've seen web articles ranging from diy folded sheet steel to the SC style bolt on. Each may have its merits but they all do essentially the same job.

Hi all, i had my normal mini pully machined to have notches in it...The pics not very good but you get the idea!

Works really well and looks the dogs!

P.s If anyone really interested i can get a betta photo!

Where did you get that done? did it cost you much?

[Sutty01]

as above and anyone have a picture if the standard mini wheel


also

kad or special components ? if you had the choise, pro's con's anyone ?

[miniboo]

i got mine from specialist components. its great

[Udo]

I didn't have to run it up on a lathe but while I was at it I thought i might as well, was fairly straight anyway as clamped it when welding and didn't try and weld it all at once and so get it too hot so you could do it without the lathe

This cost me very little when compared to the cost of the SC or KAD ones which was the reason for making it

£10 for sierra wheel
favour off mate for lazer cut bits but could be hand cut
£20 for welding which included the sensor bracket

[01smartc]

I had it done by a mate.. cost me a round of beers! lol

[Tomf]

Do you think he would consider making up another one? lol

[Sutty01]

i just hope this solves my lumpy running

[Udo]

No, mate moved to Holyhead island to work for a race team or something so dont have access to lazer cut bits anymore and i'm not cutting them by hand
