I succeeded in fabricating a center shifter for the Muncie tranny

Anyway, since I certainly obtained the big hint from the Saginaw shifter I appreciate Weedburner very much.

 

Okey

 

Damn man it's a shame to cover that...

yeah..

 

I see a lot of great engineering in the whole car, nice job

 

I can see where the tight fit of linear bearings on the slide sections would require a swing mechanism. The original Saginaw version had long tubes for the rod guides which required a looser fit to allow for swing alignment. The Toploader version uses simple 1/8" long holes in the guide plates which can accomodate the swing and still maintain a tight fit. Much lighter than my original version too.

To accomodate for the swing at the shift levers, i threaded fixed studs into the shift levers themselves. The part of the sliding rods that engages the shift lever studs have a vertical slot to allow for the arc as the shift levers move front/back from neutral. Same on both versions.

 

This thing is pretty awesome, I would patent it

 

No problem at all, happy to provide the inspiration.

Like i told Tony, to me it's a lot like porting your own cylinder heads- the first port is mucho fun. Making seven more of the same thing kinda sucks.

 

Wow, that is impressive in both that one guy comes up with something that works and another half way around the world applies what he saw to his and makes a few improvements along the way.

The rest of the little roadster looks to be serious 100% hotrod too. No nonsense or extra fru fru just a well thought out pure and simple hot rod.

 

very nice!

 

Tano, thanks for the pics, awesome car! Love it!

 

Looks good, good job there

 

I have no idea on what you're sayin', but I'm impressed as hell with the fab work, the pair of ya.

Does not look in any whay amature. Very professional. Iceman

 

If the stud is not used, I think that the Saginaw shifter of Weedburner was also functioned well.
Incidentally, my shifter doesn't have the bearing.
I attached linkage by the pin which the friend made, and the clip of Muncie without using a stud.
A pin does not interfere with the movement of the linkage like a stud.
And pendulum mechanism is more important for the top of a rod than a lever rather.
The pendulum of a rod was made so that it could exchange easily, when it wore out.
In fact, I had a different plan for center shifter.
The shifter that my friend had designed had the quality of a formula car that used the rod and Heim Joint.
And, reverse had a similar linkage to not the rod type but 1st - 2nd.
However, Heim Joint deprives of the space for the gas pedal of tight model T.
Therefore, I misappropriated the design of the shifter of Weedburner.
I got the space for a gas pedal by flat pin and simple linkage.

And, to drive the road of the snow, I need to cover tranny.
Therefore, to give priority to the space of the gas pedal including the cover, I have
improved this shifter. HaHa

 

If tranny is not covered, my foot becomes a chilblain.. HaHa..

The pictures in the snow are great!

Great work on the shifter, too.

What about using spherical bushings for the front rod guides to allow for the slight angle change?

If i were to re-design the Saginaw version, i would install vertical rod ends directly into the top of the cast iron maincase, and eliminate that big plate i made to mount the rail guides.

I was going to install vertically mounted rod ends in the top cover of the Toploader version, but felt the tin cover would need reinforcing to be stiff enough for that. In the end, simple holes in the topcover reinforcements were lighter than using rod ends, and easily accomodated the angle change. I did make a plate aluminum top cover for the Toploader with vertical rod end guides, but it's quite a bit heavier than the reinforced thin SROD "heco en Mexico" cover that i went with.

 

Borrowed from another thread on here, here's another way to do a center shifter...



The big difference between this and the topmount version Tano and myself are using... my shifter has a total throw of 4" at the top of the knob. The 12"-14" throw of the sidemount above might be more traditional, but the ergonomics of a topshifter are tough to beat when it's time to bang some gears.

 

Because the shifter was an obstructive protuberance my right leg was always uncomfortable.
And linkage rod was also a troublesome protuberance.
I did cut out the cover reluctantly, in order to step on gas pedal.
However, because the linkage rod and the shifter had moved, wide space was secured.


This structure is named Tano shifter. HAHA

 

The top of the rod swings 0.4 mm by the cam mechanism.
The linkage lever does 0.2 mm slide up and down.
And the shifter side can swing 0.2 mm by only the pin and the clip.

 

I attached the pix.
Please set up the rod to the center surely.
If it is not correct, you cannot adjust the rod.

 

It should be level in order that a rod may go in and out correctly.
Please measure the range where the rod top and lever swing in your tranny.
The shifter functions smoothly if the top and the joining section are faithfully built in those measurements.

Because my English is poor, I am not convinced whether it is possible to explain correctly of it....

 

The more I look at this, the more I can see what a well made item it is.

Well done.

Mart.

 

I work in the semiconductor field and some of our equipment is made in Japan, as well as the manuals. I have to say how much I enjoy reading your Japanenglish. It is very polite and descriptive while being precise. Have no worries about your English as far as I am concerned.

 

Hi again Tano.Thank you again for the excellent pictures of the shifter fabrication.
Also a BIG thank you for the pictures of your rod.Looks very well thought out and assembled.Hope you enjoy it for many happy years and miles.
Good luck.Have fun.Be safe.

very nice, i'm fighting the same thing on my 39 coupe with a top loader 4 speed and hurst shifter

 

I have to agree there. I was impressed the first time I saw it and the more I look at it the more thought and engineering I see in it.
