Just did a writeup on converting Happ Shifter from single button to dual

[arcadepcnut]

This writeup is a modification to the Happ Shifter that has a single microswitch that is triggered when putting the shifter into high gear.

This shifter is very cheap and easily attainable but didnt quite do what I wanted it to.

Please read my writeup if you are interested in any of the following.

Highlights of this mod:

*Shifter clicks when pushing up and down
*Shifter is held manually in position the same as holding a button down or shifter can be momentarily   pressed in a direction to press a button
*Shifter returns to center
*Shifter is still as strong and robust as the original
*Shifter can be returned to original with minor effort
*Shifter used can be found second hand for cheap as it was used all through the 80's till current.
*Parts are cheap for the mod

Please get back to me if the mod helped or hindered you or any suggestions for improvements. Right now I have it installed in my breaktime racing cabinet and it works great.

My breaktime project can be found below. My cabinet in its current form looks much different than the webpage below shows. I intend to update soon after I get done adding the Fanatec force feedback wheel.

Cool! Looks good - read through it. Only one thing caught my eye

You say: "But if you have more money than time this mod might be right up your alley."

I think you meant it the other way around. No biggie, I just read the sentence a few times.

Very nice writeup and nice for you to document.

Excellent mod.


How are the square tubes mounted to the unit though?



It looks like it is just a bolt between the spring bolt and the tube wall, but seems like it would not be a very sturdy mount, as there would be a lot of extra space in there.

You are correct in your mounting assumptions. its sandwiched there between the bolt and the nut. It isnt going anywhere. not even with a hammer. I tested it

That's cool, and I guess for the great cost savings in doing the mod, it certainly wouldn't hurt to have to at worst occasionally tighten the bolt, and it isn't like it is going to be under the abusive circumstances that an actual cab on route would have to endure.

I was actually looking at the shifter right now to see what you are saying. if you notice when the stick is pushed left or right (up or down) it is actually pushing against the bolt that is holding the spring guide block in place. so I dont see how anything can move and even if the bolt was to loosen the pressure of the springs would hold it in place. Maybe Im thinking wrong. But I actually loosened the bolts a tad the ones that go through the unit and moved the stick lup and down from high to low and nothing moved. so I dont think it will be a problem for anyone. thanks for the tips though!
