Another thought: Is there anything in the method or geometry of moving long lever that could change the ratio. I can't see it and am going under the assumption that as long as the lever connect point is at the distance to provide a given ratio, it doesn't matter what the shape of connection piece to pedal is. Currently instead of straight across, I have an "L" shaped piece between pedal and lever.(snip)


There would be no difference in the (parallel) plane of motion. Of course, if the lever mechanism is not strong enough, then the lever could twist or bend and that could change the ratio depending upon where the deflection occured.

Thanks, Craig. I didn't think so either but was throwing it out to see if I overlooked something that was obvious to everyone else.

I am concerned about flex as well so have made it very beefy. Probably way more than needed but will most likely keep it that way. Final design and dimensions still in progress but makes it so much nicer done this way instead of having a straight across rod as was in one of my early pictures.

Flex???? Just use any modern car/lite truck (of equal size) that u already own to compare dimensions of material used. Should not have to go any heavier than that.

NOTE that the F Explorer pedal assembly i'm using had thin nylon bushings in the pedal hinge which seems skimpy to me but it holds up just fine.

Use any modern or even not so modern production vehicle as a model for materials needs and applications. How could anyone go wrong with that????

You're right, but I'd rather err on the overkill side and also need some thickness in that piece for the bearing I'm using. Another benefit is to keep the different metal sizes needed to just a few pieces.

Am not saying this is the best or only way. Assuming the possible bleed problem is solved and actually get some numbers that are reasonable, will photograph and provide details and measurements of what was done. If anyone else wants to try one, this will be a starting point and any changes can be made they feel appropriate or more comfortable with.

I'm still not sure about the nearness of shift linkage, but have decided to go with what I have. The Ultra rod looks like it will clear barely but could be bent if needed. The stick maybe a lost cause without having one to look at in detail.
