Back to this gear change.......

There as got to be someone on locostbuilders that as made their own push button gear shift ?

Would you share your secret ?

The prices I'm been quoted seem a bit steep for a solenoid and a couple of buttons.

Jon,

I seem to remember Martin's brother who's the electrician making is own with two solenoids, can't remember his name though, is it Keith??

HTH,

Check out Pathfinder's photo archive - he's making them now.

Was always going to do it but never got round to it. Plenty of 2 way solenoids on ebay. When we loooked at it we found some great tiny little micro switches from maplins. Cost next to nothing and would be ideal for a solinoid operated paddle shift.

Jon,I used two starter solenoids,one for up and the other down activated by two buttons on the steering wheel.I still have the parts and they are yours if you would like to rig them up.This was used on a formula three sprint and hillclimb car that came 5th in the British Sprint Championship.the gearbox was a Staffs sequential.We used an ignition cut for full throttle changes.The sequential mechanism was not as fast as the Bike boxes but we got it to shift.It was not 100% reliable occasionally changing two gears in the heat of competition but for road use it may be fine.

Martins brother Steve did make his own push button gear shift. Might be worth having a word with him Jon.

Yea, I remember seeing it, I also know how busy he is at the mo, may pop over Saturday for Pie n Peas and an arm twist.

I just paid £200 for my Kliktronic, was used a few times on a project at Queens University Belfast, first saw it on E bay where it did not sell, so they are about at almost sensible money

I did a circuit of my own for this using starter solenoids and a few micro switches on the solenoids to momentarily cut the spark while they were actuating, not fully tested it though, as i have more projects to do than time.


I don't do electronics but would I be correct in thinking I just interrupt the supply to the coils ? Would one coil do ? How do/would I make it so quick to be worthwhile and at the correct time ?
