I'm sorry if this has been asked before but the "search" function is driving me batty!!

For those of you who've done an electric reverse, which make/ model starter motor did you use.....?? (pictures welcome!)

Thanks in advance

The best starter to use is.... whatever will attach to the ring gear you're using

I know my bro has made a few using blade starters and ring-gear. Only trouble is trying to machine the ring-gear it's bloody tuff stuff....

Thanks guys.

Is it starter motor first then ring gear or vice-versa? Also, I can't see the starter motor details listed (Fiesta 1.4? Micra? Scooby?)

I would of thought that the motor was first on the list and then get the gear cut to suit?

(Oh, and, any idea where/ who to cut the gear?!)

I recently saw a whole car flywheel sandwiched between the diff flange and cv joint with a starter motor attached to it. Probably quite slow, definately crude but it did work.

That's an option I've looked at but have decided to try the "front end ring gear between the prop and sprocket adaptor" method

If you are running a bike battery it might not be sufficient to run a car starter. I tried a Vauxhall 1.4 starter with mine , bike battery strugled to turn it even with the ZX9 doing 6000rpm !
I now use a ZX9 starter with ZX9 first reduction gear engaging with a Suzuki gear fitted to the engine end of the prop, the starter and first gear all mount on a sliding cradle, it works well.
I made mine but you can buy this ready made , can't remember who sells them
And bike starters weigh a lot less than car

dont know if this has ever been mention but one of the best ways to cut one off gears i know of is to wire erode them, we have a wire eroder at the engineering centre i work at and it cuts through basically any metal no trouble whatsoever, and can cut straight corners as near as makes no difference (no tool tip radius)
