this is nice, not fast shifting, but a nice cheap option!
The Holinger box is more for Race freaks!
True its nice looking and a interesting option, but with 20kg extra weight and cost of over 4k euros its rather steep this is nice, not fast shifting, but a nice cheap option!

I imagine its also a normal foot clutch operated system
I keep thinking about this concept, and cant wait to see one in action.
If you can make it work, I want one.
Have you thought about making the selector levers like a yoke, with a bearing?. Firstly, to reduce friction, but also centralize the forces on the lever and avoid any flexing that may be encountered with a pin system + lever on the side.
Obviously the paths milled into the wheels would have to go all the way through, and may need to be modified slightly so there is enough meat left...

very nice, am I right to assume that you need some switch indicating whether your are in neutral and rear ?
This system would go from all gears from R to 5th right in steps of 1 gear ?n I am about to change my gear selection based
on some beared mechanic that would make the selection more precise but keeping the H pattern. Just waiting for the registration of the
car......no changes on the working piece before that.

Hi, I looked to rollerbearing, but it would make it a bit lumpy.
I'm looking at another way to do it as we speak.
Don't have a groove, but a profile on the outside of the disc, and springload the roller onto the disc.
For the actuation I need 20 kg springload.
If I make 2 discs, one could make adjustments between the two output actuations. So not finished yet.

Jeff,
Off topic I know, but as one man in business to another, how are you finding the Banks your end?
In the UK there is the fact we have a base rate of 0.5%, but the Banks who are under pressure by the Govt, are still charging a WHOPPING absolute min of 11.5%, if that is, you can get it that low!
No wonder Businesses are put off borrowing money!
Generally Business would expect around 3-4.5% over base, so yet again the banks are trying to profiteer on a humungous basis!
Before anyone complains - If we cannot get reasonable rates, support our hardworking Staff and do reasonble business - this impacts our chance of finishing our Ultima builds! So there is the link Mr Stig!

It's a bit early to post, but I'm currently working on one. Have the first tests done on some simple base, and I'm quite pleased with the result.
It's a simple solution which only replaces the H shifting pattern towards a front backward moving one, so avoiding wrong shifts.
Still need to operate the clutch like normal, works on a motorcycle gearbox principle.
Aiming lowbudget pricing since it ain'tmy business just my hobby.

Hello. This is Rishi from INDIA and yeah we have also designed a same type of disc but havent manufactured. but i have a few questions and i guess u may answer it.It's a simple solution which only replaces the H shifting pattern towards a front backward moving one, so avoiding wrong shifts.

the first ques. what was the angle between all the gears from Reverse neutral first second third fourth and fifth sequentially.?
Is selector and shifter disc are in equal angle measurement?
what is the distance of travel of the shifter rod when a gear is engaged? will it be equal?
what is the mechanism you have used to shift the gears? ratchet and pawl? or any other mechanism?
we have done but the mistake which we have done is the the angle which we gave for 180 degree disc is too steep. so if u can describe in detail so that it will be useful for me,
thanks
