    Building a racecar from Menards. Vol. 45. Remote Shifter

    After strapping myself into my new seat, and pulling the shoulder harnesses tight, I noticed one thing... I have to stretch to reach 1st, 3rd, and 5th gear. Fine for autocross when I'm in 2nd gear the entire time, but for open tracking when 2nd through 4th are typically used (or when just driving around on the street for that matter), this wasn't going to work.

    Solution? My latest project:
    Remote shifter...ScotWithOne_t style.

    I started out just wanting to just build some sort of spacer to mount the stock shift lever on, moving it back and to the left a couple inches. This works, but also increases the overall length of the lever, meaning an even longer throw.

    Back to the drawing board.

    I did some research online for custom shifters, and found a plethora of stock style short throw shifters, but nothing that relocated the actual shift linkage. MGW makes a custom shifter that is adjustable up, down, and radially, but this still wasn't good enough. A little more research led me to corner-carvers, and I found out that what I really needed was a "remote shifter". To my knowledge, only one company makes one (link), but there is two problems with it…well…three. First, it is designed for a first gen Mustang with a T5, so the linkage would be too long for my application. Secondly, I just really don't like the design of it. It looks pretty, but the bolt holding the flat machined part of the shaft against the shifter stub is also acting as the pin for thrust, AND as the element that bears the moment from moving the stick side to side. Thirdly (and for those of you that know me, most obviously), it cost $200.

    So I set out to design my own remote shifter. I tried to come up with some geometry to reduce the throw, but I determined that it is impossible without it binding up when you move it side to side. So I'm stuck with the stock throw, but in a better location. That can always be fixed later on with a short throw shifter with positive stops (which I should get eventually anyway). My design makes use of 1/4" X 1" steel flat bar, nuts and bolts, and one 1/4" heim-joint. Using one piece of flat bar sandwiched between two other pieces, and a 3/8" bolt through them, I am able to get fairly slop free thrust, a rigid moment, and since the two outside pieces of flat bar are spaced with another small piece of flat bar, the joint spins easily even when the bolt is tight.

    Here is the concept sketch:


    The throw should actually be slightly less than stock, since the total lever length is slightly less than the effective length of the funky shaped stock lever.
    I'm about half done. Had to stop because the bolts that hold the stock lever on are not long enough. I thought they were standard 5/16" bolts, but they must be metric. The thread pattern matches a 1/4-20 bolt, but it is 5/16" diameter. Going to have to swing by the hardware store tomorrow to get new bolts. I also have to figure out how I will mount a shift ball to the top of it. I'll probably end up cutting the flat bar just above where the linkage connects to it, and welding on some of the same 1/2" tubing to the top that I used for the horizontal link, just to pretty it up some.

    Here is the progress so far:

        Yeah, I needed a spacer. Works for now. Maybe I'll eventually replace it with some Delrin, or aluminum.

            Nice. I have one of the remote shifters from MustangsPlus in my '68. Everyone always asks wtf is that.

            I like how you sandwiched the bar in the farther back handle, as i would think it creates less bind. The problem with my shifter is that you cant tighten the bolts too much or else they make it impossible to move/spin and harder to shift. I dunno if that makes sense, hard to explain

              You should think about using shoulder bolts- perfect for your application.
              When we got to my place, I already had a candle burning. It was by "Glade", which I think you pronounce like the singer Sade, because it is an exotic candle that smells just like real pine.

                Nah...that makes perfect sense. That is one of the reasons I don't like the mustangplus design.

                A shoulder bolt MIGHT work, but you would probably have to bore out the holes on the horizontal link, and the shoulder would have to be the perfect length, otherwise you'd get a bunch of slop moving side to side.

                  i see how it will work to shift forward and backward. but i don't understand how it will get the side to side movement?

                    I saw this too. There is an incredible amount of twist being put on the factory shifter to move it over. The joints of the design won't take it that long either. If it twists at all, you're done.
                    Do I have something better? Not yet, but I'm thinking.

                      It is quite rigid. Try to twist a 6" long peice of 1/2" steel tubing. The joints are made from two peices of 1/4" steel flat bar which are welded to steel spacers about 2" apart. hard to explain in words, but it would take a tremendous ammount of torque to deform it.

                        I understand the made part, I'm just worried about the factory shift lever. Is it pretty robust inside the tranny?

                          the design just doesn't look like it will work very well to me. it might work, but not very well. i don't see you banging 3rd gear basically

                          like miekk said, any twist in the factory shifter.. or any play or movement in any one of the many pivot points will just multiply any input movement you need to make.

                            The factory shifter is prett tough as far as I know. I won't be slamming the shifter any harder than I did with the stock lever attached to it.

                            Or are you asking what would happen if the alignment is off slightly, causing bind? The answer to that is, not much. The alignment can be totally off and it will still push and pull just fine, but side to side it might bind if the raduis of the arc that the end links make are different...however I tried to make them as equal as possible. If the radii are off by a half inch or so, it doesn't change the position much when rotating a mere 13 degrees.
                            I had originally thought about putting the joint on the rear stick about 2" above where it is now, which would result in a much decreased throw foreward and backward, but I soon realised there would be significant binding when moved side to side.

                              Do you understand that without a vice, and a huge channel-lock pliers, it is nearly impossible to deform the horizontal link? And if you're talking about "twist in the stock shifter" meaning if you were looking straight down at it form the top, and twisting the stub clockwise or counter clockwise....that doesn't matter. It could be on a ball bearing and the axial load of the horizontal link would still be translated into the stock shifter stub, thereby rotating it about it's horizontal axis and moving the stick from 1st to 3rd or 5th positions.
